Koh Sulaiman Range falls into central part of middle Indus basin (Sulaiman basin) and is also located in the eastern part of Sulaiman Foldbelt. The Koh Sulaiman Range hosts the exposed sedimentary rocks which are Triassic-Jurassic Sulaiman Group comprising of Wulgai (shale, marl and limestone), Loralai (thin to medium bedded Limestone), Chiltan (thick bedded and massive limestones), Dilband (ironstone, ferruginous siltstone/marl and shale), Lower Cretaceous Parh Group includes Sembar (shale), Mekhtar (sandstone, Goru shale and marl/siltstone) and Parh (white limestones), Late Cretaceous Fort Munro Group represented by Mughalkot (shale and sandstone with rare limestone), Fort Munro (limestones), Pab (mostly marine sandstones; Dhaola, Kali and Sor Members, see below), and Vitakri (terrestrial fluvial shale/mud and sandstones), Paleocene Sangiali Group consists of Sangiali (limestone, greenish grey sandstone and shale), Rakhi Gaj (sandstone and ironstone of Girdu Member; shale of Bawata Member; both members have Deccan volcaniclastic materials) and Dungan (limestones), Eocene Chamalang Group consists of Shaheed Ghat (shale), Toi (marine to deltaic green to grey sandstone and shale), Kingri (terrestrial red to maroon sandstone and shale) and Drug (rubbly limestones) and Baska (gypsum and shale) and Kahan Group represents Domanda (marine shale), Habib Rahi (brownish white marl and limestones), Drazinda (marine shales) and Pirkoh (white marl and limestones), Oligocene-Pliocene Vihowa Group represents Chitarwata (fluvial ferruginous sandstone, conglomerate and shale), Vihowa (fluvial shale and sandstone), Litra (fluvial sandstone with minor shale) and Chaudhwan (fluvial shale, sandstone and conglomerate) and Pleistocene-Holocene Sakhi Group consists of Dada (high energy fluvial conglomerate) and Sakhi Sarwar (fluvial shale/mud, sandstone and conglomerate) Formations and Subrecent and recent alluvium (Figure 1 of [1] ; Figure 2 of [2] ). The etymology, description, contact relationship, fossils and age of formations are mentioned in detail [1] - [11] . The type localities of formations are shown well in Figure 1 of [2] [11] .

Beside the above exposed sequence, some relatively older geological formations were encounter in drill holes in the eastern plain areas. Some major hints and variations are mentioned as below. The PermoTriassic Wulgai formation consists of marine shale, marl and limestone mostly exposed in and around the Western Indus Suture. After this, the Early-Middle Jurassic Loralai Formation consisting of thin to medium bedded limestone with subordinate shale were deposited under marine condition. The Late Jurassic Chiltan Formation consisting of medium to thick bedded limestone with negligible shale were deposited under marine condition with relatively less fine clastic source. The Chiltan Limestone mostly forms peak of high mountains in Balochistan such as Chiltan, Takatu and Murdar Ghar ranges and Takht Sulaiman Range. The western slope of Takht Sulaiman Range lies in Balochistan and eastern slope in Khyber Pakhtunkhwa and South Punjab (Saraikistan). The limestone content of Parh Group is relatively low in Sulaiman foldbelt than in Kirthar foldbelt. The Formations of Fort Munro Group and Sangiali Group are being reduced toward west in the western Sulaiman foldbelt. The Mughalkot Formation has porcellaneous mudstone in the Rakhi Gaj Girdu section while it consists of shale and sandstone in the northwest. The Pab and Vitakri Formations are famous for dinosaur and other vertebrate fossils (as below). The sandstone of Ghazij Group is missing in the southeastern Koh Sulaiman Range while it is dominant in the north and west showing its source from the North West (from western Indus Suture and Afghan block). Dungan limestone is more thicker (best petroleum host) in the Zindapir and northward to Drazinda Shirani area, and also Kaha Harrand to southward, while it is thinner in the Rakhi Gaj and surroundings areas of Koh Sulaiman Range. Habib Rahi and Pir Koh Formations marl/limestones are thicker (best petroleum host) in the southern Koh Sulaiman Range (Mari Bugti hills) while Domanda and Drazinda Formations shale is more thicker in the north near Drazinda, Domanda and Mughalkot areas of Shirani.

Reference [12] (p. 132) first reported Cretaceous sandstone and crocodilian 2 or 3 vertebrae in olive shale containing bivalve Cardita beaumonti in Bara hills of Laki anticline (Sindh, eastern Kirthar foldbelt). This olive shale belongs to Early Paleocene Khadro or probably Bara Formations [13] . Later, [14] [15] described the Cretaceous sandstone from the Des valley, Mazar Drik (Balochistan; western Sulaiman foldbelt). References [16] [17] increased distribution of Cretaceous sandstone at Pab Range (western Kirthar foldbelt) where he named Pab sandstone after this type locality. He correlated the Bara, Pab Range and Des-Mazar Drik (Pazha area) sections. Reference [18] mapped the Pab Sandstone in the central and western Kirthar and Sulaiman foldbelt. The Geological Survey of Pakistan mapped (1:50,000 scale) most of the area especially the eastern part of Sulaiman and Kirthar foldbelts. Recently, present author ( [1] [2] [6] [11] [19] [20] and references therein) visited all these areas and reported distribution of Cretaceous-Paleogene boundary (Cretaceous-Tertiary boundary), Pab and Vitakri Formations. Reference [20] divided the Pab Formation into three members such as Dhaola, Kali and upper Vitakri Members. Reference [21] upgraded the Vitakri member as Vitakri Formation. Sor Member [11] of Pab Formation is well exposed in the north western part (Qila Saifullah Zhob to North Waziristan) of Sulaiman foldbelt [11] . In short, the Pab Formation is now represented by Dhaola Member (white sandstone), Kali Member (grey black weathered colored sandstone) and Sor Member (maroon shale and sandstone). The distribution of these 3 members are reported in many reports and also briefly mentioned as below. In Kirthar basin the Dhaola Member of Pab Formation is exposed in Bara and surrounding in the core of Laki anticline, the Kali Member (black weathering) is exposed in Pab Range from Karachi to Khuzdar and Karkh-Moola areas. Further north, one or only a few thick beds of Pab sandstone are exposed in the Johan-Dilband-Sor Range areas where it is included in Late Cretaceous Moro Formation. In Sulaiman basin the Dhaola Member of Pab Formation is well exposed on both limbs of north south trending anticlinoria from Takht Sulaiman area (in the north) to Maarri peak area (in the south of easternmost Sulaiman foldbelt). Westward from these anticlinoria the trends of Pab and associated other formations changed toward southwest and east west. From Waziristan-Shirani-Zhob-Qila Saifullah (northern Sulaiman foldbelt) the Sor Member of Pab Formation is well exposed (Figure 8 of [2] ). In the central east west traverse from Kingri Musakhel to Mekhtar to Tor Thana, the Dhaola Member is exposed in Musakhel areas while Kali Member of Pab Formation is exposed in the western part (Mekhtar, Tor Thana and surrounding areas). From Tor Thana to westward in the Karu-Sanjawi-Ziarat and surrounding (Loralai and Ziarat districts) the Pab Formation is missing. Here, only green and grey shale of Mughalkot Formation capped by thin unit of laterite and red to maroon and mottled clays of Vitakri Formation are exposed, while sandstone and limestones at the level of Mughalkot, Fort Munro, Pab, Vitakri, Sangiali and Rakhi Gaj Formations are missing. Here, the Vitakri laterite is capped by Dungan Limestone. This Mughalkot shale is graded further westward (west of Ziarat town) to Mughalkot shale and volcanics. Shifting traversing section further southward, the Bahlol-Chamalang-Hosri to Nana Sahib Ziarat to Sembar-Mazar Drik (Des valley, Pazha area), the Pab Formation is well exposed especially Kali Member in the north and north west of Pazha village and southwest of Nana Sahib Ziarat (southern limb of Sembar-Mazar Drik anticline). Pazha areas are found just on the south and southwest of Yaru Shahr and Ismail Shahr of Duki area of Loralai. Traversing southward extremity, the Pikal-Siah Koh to Dhaola-Andari ranges to Vitakri-Fazil Chel to Mawand-Gamboli areas the Pab and Vitakri Formations are well exposed. The sandstone of Pab Formation is dominant in the eastern Sulaiman foldbelt while westward the shale proportion is increasing (revealing source in the east/Indo-Pakistan shield). The footprints of dinosaurs and pterosaurs, large wood fossil and non-confirmed eggs were reported (see below). The age of the Pab Formation has been reported as Maastrichtian by many previous researchers on the basis invertebrate fossils such as Orbitoides (Lepidorbitoides) minor [16] [17] , Globotruncana aff. G. linnei, Lituola sp., Omphalocyclusmacropora, Orbitellamedia, Orbitoides sp., and Siderolites sp. [18] .

The Vitakri Formation [21] in type locality and surroundings consists of over bank fluvial two mud units sandwiched and capped by meandering river deposited sandstone two units [20] . The mud units are maroon, green, grey and mottled which weathered into maroon and green colors. The middle sandstone unit is relatively thin and have lenticular (pinching and swelling) nature, while the upper sandstone unit is relatively more thick and prominent. Both fluvial sandstone units are grey and white having quartzose and also muddy matrix while Pab Sandstone is mostly quartzose and marine. Their differentiation criteria are based on matrix and sandwiched fluvial muds. So far collected archosaur bones found mostly from the upper part of the upper mud unit, while lower mud unit also yielded a few bones [11] . In the Kingri area of Musakhel, the Vitakri Formation is represented by carbonaceous shale (commonly called Kingri coal) with some sandstone. Further northward, the Vitakri Formation is represented by a few centimeters to a few meters of laterite and carbonaceous shales. In the western Sulaiman foldbelt (Sanjawi-Ziarat and surroundings, Mina Tangi Sor Kach; Figure 1 of [3] ,) the Vitakri Formation is represented by a few centimeters to a few meters of laterite and lateritic muds. In the Bara Nala section (Jam Shoro District) of Laki anticline the Vitakri Formation is represented by a thick unit of red and maroon shale and sandstone. Toward west in the Karkh and Moola Zahri Range it is represented by a few to many centimeters thick laterite. This laterite of Vitakri formation in Kharzan Moola area is hosted by a bivalve (Pakiring kharzani, see as below) which is typical and unique in Pakistan. In the upper Indus basin (Kohat and Potwar-Kotli basin) it is represented by its coeval Indus Formation. The Vitakri Formation coeval in India is Lameta Formation. The Vitakri Formation has unconformable upper and lower contacts in the areas of laterite and lateritic clays while it has conformable contact in the Vitakri and surrounding areas of eastern Sulaiman foldbelt and Bara-Khadro Nai and surroundings area of eastern Kirthar foldbelt where it has reasonable thickness. The Vitakri Formation is found between the well dated Maastrichtian Pab Formation and the equally well dated Paleocene Sangiali, Rakhi Gaj and Dungan Formations and further, the presence of theropod fossils suggests a latest Cretaceous age [22] . The Vitakri Formation is considered latest Maastrichtian because it is sandwiched between well date Maastrichtian Pab Formation and Early-Late Paleocene Ranikot and Sangiali Groups of lower and middle Indus basins. The Ranikot and Sangiali Group are derived from volcaniclastic materials from the east and Deccan basalt during Paleocene. The Vitakri Formation was considered the latest Maastrichtian age (67 - 66 Ma) based on stratigraphic position, well dated upper and lower contacted formations and dinosaur fossils ( [3] , p. 47; [8] , pp. 40-41; [9] , pp. 76-77; [23] , pp. 416-418). After the deposition of Paleocene Sangiali Group in Sulaiman and northwestern Kirthar foldbelts, the eastern sources of clastic material and river direction changes from east west trend to northwest-southeast trend (or generally north south trend). The author found terrestrial fossils bivalves and archosaur in the Vitakri strata, and nautiloids and bivalves in the Sangiali Formation. All these field observations revealed that the upper boundary of Vitakri Formation in lower and middle Indus while the Indus Formation in upper Indus basin is the K-Pg boundary.

The exposed structures of Koh Sulaiman Range are represented by almost foldings with minor faultings. Traversing from east to west in the southern part of Koh Sulaiman Range, the first observed is Fort Munro anticline, then Phailawagh syncline, Moranj anticline, Beakar-Rakhni syncline, Siah Koh-Pikal anticline, Nisau-Jhabar-Kharcha syncline, Dhaola-Mazara anticline, Gambrak-Ishani-Lakha Kach-Rara Sham-Kingri-Drug More (Musa Khel) syncline, southern Fazil Chel-Mari Bohri-Vitakri Dome anticline. Traversing from east to west in the central part of Koh Sulaiman Range, the first observed is Zinda Pir anticline, then Barthi syncline, Fort Munro anticline, Manjhail-Pir Gahno Kharar Buzdar syncline, Rar Khan-East Drug anticline, Indarpur syncline, western Indarpur anticline, Kingri-Khan Mohammad syncline and anticline, Tangi Sar anticline contacted with high angle fault/syncline with eastern Drug More (Musa Khel) anticline, Drug More syncline, Musa Khel Bazar anticline. Traversing from east to west in the northern part of Koh Sulaiman Range, the first observed is Zinda Pir-Domanda anticline, then Barthi-Savi Ragha-Zamri-Sheikh Manda-Drazinda syncline and Shinghar-Dhana Sar-Koh Sulaiman peak (Shirani area of Zhob and D. I. Khan) anticline. The structures of southern part Koh Sulaiman Range and foldbelt is mapped and shown in Figures 2-7 of [1] and northern part is shown in Figures 3-8 of [2] . The detail description of structures especially foldings and faultings are provided by [1] [2] .

The reported area and surroundings host significant and huge mineral resources (Figure 1) which are shown as below. These minerals along with other natural resources can play a significant role for the development of area and country Pakistan [24] - [29] . Most of these mineral resources are the property of provinces. Keeping in mind, previously the mineral resources of Balochistan Province [30] [31] [32] , Khyber Pakhtunkhwa [33] [34] , north Punjab and South Punjab [35] , Sindh Province [36] [37] , Gilgit Baltistan and Azad Kashmir [38] [39] have been reported so far. Further, the mineral resources among basin wise were also presented for the researchers [19] . Here, the geology and mineral resources of Saraikistan area (South Punjab, Koh Sulaiman Range) is being presented.

Abrasives: Gritty sandstone from Pab Formation of Fort Munro areas and Kingri Formation in the northwest Sulaiman Range can be used for abrasive purposes. Some ochre deposits fit for abrasives while most of the ochre deposits found especially in K-Pg boundary, Habib Rahi and other formations are suitable for paint industry.

Lithium deposits: Lithium deposit in laterite of different horizons may host lithium and can be explored and analyzed in different lateritic, alluvial and other

formations. The laterites are significant because India is producing lithium from laterite just east of boundary. For lithium the Tor Ghundi pegmatite is significant for exploration.

Laterite and ochre: Low grade but large deposits of ferruginous shales/clays and ochre and aluminous found in Vitakri, Kingri, Drazinda, Chitarwata and Vihowa and other younger formations. The deposits of Fort Munro, Rakhi Gaj and its vicinity areas found in the Vitakri Formation (equivalent to Indus Formation of Upper Indus Basin). The disconformity in the Late Eocene Drazinda Formation and Early Oligocene Chitarwata in the eastern Sulaiman fold belt also seems significant for ochre and lateritic materials. The possible low grade but large deposits of Ochre/Iron from Chitarwata, Vitakri, Drazinda formations and Vihowa group of Sulaiman Foldbelt have been expected.

Celestite deposits: The celestite mineral showings are found in the Eocene limestone of D. G. Khan and Rajan Pur areas of South Punjab, so the Eocene strata of Sulaiman foldbelt are also significant for further exploration because the celestite associated with extensive gypsum beds/deposits which show further exploration for celestite [40] [41] .

Fluorite deposits: Previously fluorite deposits are found from Dilband and Zahri Range (western Kirthar foldbelt) and Mekhtar and Loralai and surroundings (western Sulaiman Range) in the Loralai and Chiltan/Zidi Limestones [40] [41] . Fluorite deposits are found in Mekhtar, Murgha Kibzai and Loralai area (western Sulaiman Range) in Loralai and Chiltan Limestone. In this way, fluorite can be prospected in the eastern and northern Sulaiman Range because of vast exposures of host limestones. The Chiltan Limestone are well exposed in the major peak forming anticlines/anticlinoria such as Shin Ghar, Dhana Sar and Takht Sulaiman peak and Wana (South Waziristan) and Razmak (north Waziristan). This belt started from Toi Sar Thana area (north of Musa Khel Bazar) and extended upto Shirani and Waziristan regions. The exploration of fluorite in these belts may be successful. The light green fluorite from Loralai, Pakistan is best for thermoluminiscence (TL) [42] .

Lithium, REE, gold and silver, zircon and heavy minerals in placer deposits: The heavy and resistant minerals like gold, tungsten/sheelite etc, titanium/rutile, zirconium/zircon, ilmenite, etc, may be found in placer deposits of Indus River which cover the large area in south Punjab. The exploration of these placer minerals may be beneficial. The exploration of Lithium mica and associated with other minerals as in laterite of India and REE in placer sand and fluvial deposits of Koh Sulaiman Range and its Daman area and also in Cholistan sand are significant.

Ironstone: Fort Munro ironstone deposits are found in Early Paleocene Girdu (Gorge beds) Member of Rakhi Gaj Formation [4] [5] . This iron is found in the eastern and western limbs of Fort Munro anticlinorium. Its chemical analysis shows Fe₂ O₃ 14% - 21%. The iron is found mostly as ferruginous sandstone and minorly as ferruginous shale. The greenish grey and red spotted and red wavy laminated sandstone show iron (alongwith phosphate) mineralizations found in both Girdu and Bawata Members. The hematite and possibly hydrous iron silicates (chamosite and glauconite) are major iron mineralization. This ironstone deposits are very large but low grade. It’s testing for steel, cement and other industries may prove worthy. The extensive iron beds thickness varies from 2 to 50 m. The highly anomalous thickness is found in Khar, Top Girdu, Fort Munro and Rakhi Gaj and its vicinity areas. Its reserves seem to be 400 million tons from surface exposure to easily mineable depth 200 m. Its mining is easy due to exposure above the ground surface, and at places low dips. This iron deposits seem to be feasible due to huge but low grade raw materials, favorable locations on metalled road and near to D. G. Khan railway station [4] [5] .

Gemstone and jewelry resources: Indus river placer is very significant for gold-silver-platinum panning and further exploration. The chalcedonic silica like Chert, flint, jasper, etc, along with other significant and beautiful pebbles and cobbles are found as detritial/placer in the conglomerate and conglomeratic sandstone/gritstone are found in the Oligocene-Pliocene Vihowa Group and also in the Pleistocene-Holocene Sakhi Sarwar Group in the Sulaiman foldbelt. These are significant for jewelry resources as found relatively easy. Further beautiful calcite veins are commonly found in the limestone of different ages especially the Loralai and vicinity regions.

Agromineral resources: The Sulaiman basin has extensive reserves of shales/clays, so Alum shales exploration may be encouraged. The exploration for rock phosphate should be accelerated because Pakistan is an agricultural country and its demands are increasing. The Tertiary, Cretaceous and Jurassic sequence in Sulaiman range were studied by [43] . They found black phosphatic nodules with 5% P₂O₅ in Domanda and Drazinda shales, which are encouraging for further study. The Rakhi Gaj area show nodules with 5% - 20% P₂O₅ and Zinda Pir area show 5% P₂O₅ of D. G. Khan district in Sangiali group (Sangiali, Rakhi Gaj and Dungan formations) and lower Ghazij/Chamalang group (Shaheed Ghat shale). Phosphate nodules are found in about 20 m shale interval of probably Rakhi Gaj formation. Nodules with <5% phosphate in Late Cretaceous Mughalkot formation in Karim Kach Khwar to the east of Kurgali (on Mughalkot and Dhana Sar road section) are found [43] . It has been reported from Eocene Chamalang Group (Ghazij Group), and Paleocene Sangiali Group (Sangiali and Rakhi Gaj formations) in the Sulaiman foldbelt [25] . There is little or no economic value due to its low P₂O₅ content [44] but indicates for large deposits. Further try should be made because Pakistan is agricultural country and large money will be saved by reducing imports. The phosphate from green and black shale and greenish grey sandstone of Mughalkot formation and green to greenish grey shale and greenish grey to red spotted and red wavy laminated sandstone of Rakhi Gaj (both Girdu and Bawata members) formation seems to be significant [4] [5] [25] .

Cement raw material resources and huge gypsum deposits: According the new hypothesis presented by [45] that calcareous clay resources of Pakistan can be used ecofriendly for production of cement instead of Limestone Clay Cement LC³ [45] . This Limestone Clay Cement (LC³) is commonly being used in Pakistan but ecologywise more dangerous and economic wise more expenditure. The clay resources can be used for cement industry ecofriendly. Previously clay is being used about 25% in Cement preparation. If new hypothesis will be adopted, the area has huge and vast clay/shale deposits for cement industries installation. Only Lucky cement at Pezu (Khyber Pakhtunkhwa) and D. G. Cement at Zinda Pir anticline (South Punjab) are working now. Cement Industry raw materials are huge in Pakistan and especially in Sulaiman basin. The rocks generally contain 50% calcium oxide, less than 5% silica and less than 1% iron oxide making suitable for cement. A small fraction of resources are being used by cement industries in Pakistan. More than a dozen cement industries can be installed in the Rajan Pur and D. G. Khan districts on the foot mountain of Sulaiman foldbelt. The cement industry suitability will be strengthens by the close occurrence of raw materials like limestone, gypsum and shale which will be provided to industry by belts and not by trucks. Pakistan has lowest per capita cement consumption and paying several hundred million rupees every year for calcium chemicals and also rapidly increasing population, it is highly desirable and vital to take step for extending cement, lime and calcium chemicals industries, so that the country will be self-sufficient with cheap rates and able to export these materials to earn foreign exchange. Inexhaustible reserves of limestone, shale and gypsum are found in Saraikistan area (as shown below). It is vital to take step for installing more cement, lime and calcium chemicals industries especially in Zinda Pir Ziarat, Zin, Mahoi, Gulki/Taunsa, Sorra, Kharar (Kharat), Pir Gahno, Kachiwanga Luni, Rakhi Gaj, Dalana and other areas of Taunsa area and D. G. Khan District; Chachar-Maarri, Harand (Kaha), Sakhi Bor Bakhsh and other areas of Rajan Pur District; Draban, Domanda, Mughalkot, Shirani, etc areas of D. I. Khan District; Sham, Phailawagh, Beakar, Pirkoh, Habib Rahi, etc areas of Dera Bugti District; Lakha Kach Rakhni, Kofi, Nodo, Ishani, Gadumra, Bala Dhaka, Bahlol, etc areas of Barkhan District; Chamalang, Nisau, Bohri, Safed, Mawand, etc of Kohlu District; and Kingri, Drug, Zamri and other areas of Musa Khel District due to close existence of raw materials limestone, gypsum and shale can be provided in wheel belts. Due to location in central Pakistan, these cement industries will provide cement easily to Balochistan and every part of country and also for export.

References [4] [5] [25] reported gypsum 764 mt upto 50 m easily minable depth and 28.5 billion tons of estimated total reserves (measured, indicated, inferred and hypothetical) of Sulaiman foldbelt. The quality of gypsum is good as impurities are less than 2% based on chemical results of 125 samples. Chemical analyses show that CaO content varies from 30.84% to 32.24%, SO₃ from 45.75% to 48.36%, and H₂O from 17.62% to 18.62% [4] [5] [8] . There are 4 to 15 beds of gypsum in Baska Formation with cumulative thickness of 5 m to 25 m in Sulaiman foldbelt while one bed (0.3 m - 6 m) of gypsum in Domanda formation in only southern Sulaiman foldbelt. Rajanpur District hosts gypsum deposits of Giandari-Chachar-Kaha Harand-Sakhi Bor Bakhsh-Khaan gypsum belt about 2 billion tons/bt upto 200 m depth and 33 million ton/mt upto easy mineable 50 m depth. It hosts Late Cretaceous Fort Munro Limestone at Khan Sakhi Bor Bakhsh (1 bt), Paleocene Dungan Limestone at Chachar-Maarri (1 bt), Kaha-Harrand (1 bt) and Sakhi Bor Bakhsh (small deposits) areas, and Chacha-Beakar-Kalchas (3 bt) of western limb of Fort Munro-Maarri anticlinorium, and Eocene limestone of Drug, Habib Rahi and Pirkoh formations in eastern limb (30 bt) of Fort Munro-Maarri anticlinorium. It also hosts vast and huge deposits of shale/clay (see below) in Shaheed Ghat, Domanda and Drazinda formations and others at Chachar-Maarri-Kaha-Harrand-Sakhi Bor Bakhsh-Khaan areas. Dera Ghazi Khan District hosts gypsum deposits of Rakhi Gaj-Khandor gypsum belt estimated 1 bt upto 200 m depth and 22 mt upto 50 m depth and southern part of Zinda Pir anticlinal gypsum (U-shaped belt) deposits estimated 2 bt upto 200 m depth and 44 mt upto 50 m depth. It hosts limestone deposits 1 bt of Late Cretaceous Fort Munro limestone exposed at Rakhi Gaj, Girdu and surrounding areas, 1 bt of Paleocene Dungan Limestone at core of southern Zinda Pir anticline, 20 bt of Eocene limestones of Drug, Habib Rahi and Pirkoh formations in Rakhi Gaj-Khandhor area and 20 bt of southern Zinda Pir anticline. D. G. Khan cement industry is also using this Dungan Limestone. It also consists of huge and vast deposits of shale/clay (see below) in Shaheed Ghat, Domanda and Drazinda formations and others at Rakhi Gaj-Khandhor-Ronghan areas and southern Zinda Pir anticline. Taunsa area hosts gypsum deposits of northern Zinda Pir anticline gypsum belt estimated 2 bt upto 200 m depth and 44 mt upto 50 m depth, Sorra-Kachiwanga-Jisa Sharif gypsum belt estimated 1 bt upto 200 m depth and 22 mt upto 50 m depth and Manjhail Kharar gypsum loop estimated 3 bt upto 200 m depth and 66 mt upto 50 m depth. It hosts limestone deposits estimated 1 bt of Parh limestones (Early Cretaceous) exposed at Hinglun-Burg Pusht area, 1 bt of Dungan limestones at northern Zinda Pir anticline, 3 bt of eastern limb of Hinglun-Rarkhan thrusted anticline (Manjhail Pachadhi nala, Hinglun and Kachiwanga Luni areas), 3 bt of northern plunge of Fort Munro anticline (Hikbai, Mubarki-Sorra, Pir Gahno and Kharar areas), 20 bt of Eocene limestones of Drug, Habib Rahi and Pirkoh formations at Sorra-Kachiwanga-Jisa belt, 30 bt of Manjhail syncline, and 20 bt of northern Zinda Pir anticline. It also hosts vast and huge deposits of shale/clay (see below) in Shaheed Ghat, Domanda and Drazinda formations at southern Zinda Pir anticline, Manjhail and Sorra-Kachiwanga-Jisa areas. Sulaiman huge gypsum deposts is considered among the largest deposits in the Global World. Recently, Reference [46] compared the chemical analyses of Zinda Pir gypsum (Pakistan) with Iran, Türkiye and Spain gypsum. The XRD studies [46] revealed gypsum, anhydrite, magnesite and dolomite minerals of Zinda Pir gypsum deposits, however, they [46] mistyped the two beds (instead of 5 - 7 beds) reported previously from Zinda Pir, while in actual author MSM in 2000 paper mentioned the Zinda Pir gypsum beds varing thickness 1 – 4 m and later the reference [4] on page 60 mentioned 5 - 7 gypsum beds.

Ceramic mineral and clay resources: Vast clay/shale resources are found in the area. Taunsa district represents Shale reserves are 4 bt from Cretaceous Mughal Kot, Fort Munro, Pab and Vitakri formations, 5 bt from Paleocene Sangiali, Rakhi Gaj and Dungan formations, 300 bt from Eocene Shaheed Ghat, Drug, Baska, Domanda and Drazinda formations and 50 bt of Oligocene-Holocene strata. Dera Ghazi Khan district hosts Shale reserves are 4 bt from Cretaceous, 5 bt from Paleocene, 200 bt from Eocene and 50 bt from Oligocene-Holocene strata. Rajanpur district hosts Shale reserves are 1 bt from Cretaceous, 5 bt from Paleocene, 300 bt from Eocene and 100 bt from Oligocene-Holocene strata. Various types of Clay deposits are found from Ghazij, Kahan and Vihowa groups of Sulaiman Foldbelt. Bentonite is non swelling type of clay with white, grey and brown colors and high calcium %. To convert them into swelling type, it is converted into sodium bentonites by Base Exchange process. Bentonite derived from weathering and erosion of igneous rocks. Presently it is also observed in the Gadumra (Barkhan) and eastern foothills of Sulaiman range of Rajan Pur, D. G. Khan and D. I. Khan districts. It is used for drilling mud. Fuller’s earth is nonplastic clay usually contain appreciable magnesia. The main producers are Taunsa area. Fuller’s earth was formerly used for fulling or cleaning woolen fabrics and cloth, its absorbent properties causing it to remove greasy and oily matters. Its modern use is reefing of oil and fats. It is greenish grey, bluish grey and greenish brown clay with soapy feel. The D. G. Khan deposits show SiO₂ 49.6%, 46.20%; Fe₂O₃ 6.66%, 8.76%; Al₂O₃ 11.94%, 22.86%; CaO 9.12%, 2.43%; MgO 3.13%, 1.94%; Na₂O 0.25%, 1.25%; K₂O 1.94%, 2.62%; and loss on ignition 16.18% and 12.65%, respectively [47] . This clay is relatively pure illite with a base exchange capacity of 50 compared with 40 for standard illite and 106 for English montimorillonite [44] . Reference [48] reported resistant, brownish yellow 1.5 m thick fuller’s earth/volcanic ash on the contact of Litra sandstone and Chaudhwan mud from Zinda Pir Taunsa area, Its chemical results (wt %) show SiO₂ 59.6%, Fe₂O₃ 2.27%, Al₂O₃ 16.98%, CaO 2.95%, MgO 2.91%, Na₂O 2.62%, K₂O 2.09%, TiO₂ 0.15%, MnO 0.03%, P₂O₅ 0.06% besides volatiles 9.32% [48] . Thick immense reserves of fuller’s earth upto 30 m thick are observed by Hilal A. Raza in Domanda and Baska formations in Rakhi and Sebdi nalas. The deposits upto easily mineable depths 100 m are more than 1 billion ton of eastern Sulaiman foldbelt [35] . Fuller’s earth is formed in the flood plains of Tertiary river channels. In recent years it is being utilized in oil refining and other industries in the country. With activation this clay may be used in vegetable oil and ghee industries. It is also being used in insecticide, foundries and steel industries. Its demands are being increased. Reference [35] collected samples of fuller’s earth from Domanda and Drazinda shales of western (Zin area) and eastern limb (Mahoi area) of Zinda Pair anticline, Tehsil Taunsa, Dera Ghazi Khan District and their chemical results show SiO₂ 50.86% to 64.01%, Al₂O₃ 9.79% to 17.18%, Fe₂O₃ 3.10% to 6.89%, CaO 6.41% to 12.20%, MgO 2.01% to 5.64%, P₂O₅ nil and loss on ignition/volatiles 8.87% to 12.60%. He estimated reserves of 10 mt upto 200 meter easily mineable depth in Zinda Pir anticline areas. Huge reserves of fuller’s earth are observed in Domanda, Drazinda and Baska formations in eastern Sulaiman Range. Reference [25] shows its existence from Dera Bugti-Rajan Pur-D. G. Khan-Musakhel-D. I. Khan and Barkhan-Kohlu districts. Fire clay beds are associated with many coal horizons in the Sulaiman foldbelt. The possible Fire clay from Chitarwata, Rakhi Gaj, Vitakri, Drazinda formations and Vihowa group of eastern Sulaiman Foldbelt seems to be significant. Fire clay is resistant to shrinkage, abrasion and corrosion under high temperature and withstands thermal spalling. It is very low in iron oxide content < 2% and high in alumina (24% - 45%). It is being produced at Kot Kaisrani (Taunsa). In actual the fire clay and fuller earth deposits are same (mentioned in fuller earth) mined from many places at Kot Kaisrani, Mahoi, Zin, and other areas.

Quartzite, millstone and silica sand: The hard quartzose sandstone of Pab Formation is considered as Quartzite. Its vast deposits (into billions) are found in Mubarki-Fort Munro-Maarri anticlinorium and Hinglun-Luni-Andarpur areas. Due to its high hardness it was previously used for floor mill. Quartzite can be utilized by steel mill. Large deposits of silica sand in the sandstone of Pab Formation and Vihowa group (mostly in Chitarwata Formation of Zindapir and others).

Marble, dimesion stones, decorstones, gemstones and jewelry resources: South Punjab hosts significant decorstones, gemstones and jewelry resources. Large reserves of limestone (commonly used marble and dimension stones) are found in Koh Sulaiman. Fort Munro limestones in Rakhi Gaj and surroundings, and Dungan limestones in Harand, Maarri and Chacha-Beaker-Kalchas of Rajanpur, Rakhi Gaj, Khandor, Fort Munro, Bawata and surroundings and southern part of Zinda Pir anticline of D. G. Khan district, northern part of Zinda Pir anticline, Hikbai-Mubarki, Kharar, Ronghan-Sorra, Poadhi and Pachadhi nalals of Manjhail to Pir Gahno, Hinglun to Luni Kachiwanga and Burg Pusht areas of Taunsa can be used as dimension stones and tiles preparation. Beautiful pebbles, cobbles, chalcedonic silica like chert, flint, jasper and others are found as detritial in placer deposits like conglomerate and conglomeratic sandstone/gritstone of Vihowa and Sakhi Sarwar Groups and also in terrace and present day river/streams/channels in eastern Koh Sulaiman Range and its Daman areas. These can be used in jewelry which contributes a lot for the development of South Punjab. These deposits are easily accessible from D. G. Khan, Rajanpur and Shadan Lund railway stations.

Construction stones: Large deposits of construction stones like limestone, sandstone, shale, conglomerate, gravels, sand and muds found from Taunsa, D. G. Khan and Rajanpur districts (Koh Sulaiman Range and its foot mountains Daman areas). Vast sand of sands are found in Indus, Chenab and Sutlej rivers and also in Cholistan desert. The large limestone deposits (see above) are found from Fort Munro, Dungan, Drug, Habib Rahi and Pirkoh formations. The large sandstone deposits are found in Pab, Vitakri and Rakhi Gaj formations and Chitarwata, Litra and Chaudhwan formations. Further gravel, sand, silt and mud are found from Chaudhwan, Dada, Sakhi Sarwar formations, terrace, fan and present river gravel and alluvium deposits. The gravels from Dada and Sakhi Sarwar formations and in alluvial terraces and in river channels are being used in Sakhi Sarwar and Taunsa crushing plants. Like this crushing plants can be installed in Lundi Saidan, Maarri and Kaha Harrand areas. The limestone deposits are shown in cement resources (as above) and shale/clay deposits are shown in clay ceramics deposits (as above). Taunsa district represents Sandstone reserves are 250 bt from Cretaceous Pab and Vitakri formations, 3 bt from Paleocene Sangiali and Rakhi Gaj formations, 400 bt from Oligocene-Pliocene Vihowa Group (Chitarwata, Vihowa, Litra and Chaudhwan formations) and Pleistocene-Holocene Sakhi Sarwar Group (Dada and Sakhi Sarwar formations). Dera Ghazi Khan district hosts sandstone reserves are 250 bt from Cretaceous, 3 bt from Paleocene and 250 bt from Oligocene-Holocene strata. Rajanpur district hosts sandstone reserves are 200 bt from Cretaceous, 2 bt from Paleocene and 350 bt from Oligocene to Pliocene strata. These deposits are easily accessible from D. G. Khan and Shadan Lund railway stations.

Coal resources: Dera Ghazi Khan and Rajan Pur coal showings are reported from Late Eocene Domanda and Drazinda Formations and Oligocene Chitarwata Formation in Sulaiman Daman. Reference [49] reported coal from Domanda formation of Rakhi Munh area, Dera Ghazi Khan District. Reference [50] reported Domanda coal from Upper Tuso, Nabi Bakhsh Thal Nala and Khan BMP post area of Rajan Pur district, Mahoi and Zain BMP post area of D. G. Khan district, Eocene Drazinda coal from Haft Gath/Shaheed Ghat area (Zinda Pir Ziarat area), Oligocene Chitarwata Formation coal in Khandor BMP post area of D. G. Khan district. Reference [49] reported chemical analysis of Rakhi Munh Domanda coal like moisture 11.19%, Ash 21.83%, volatile matter 34.63%, fixed carbon 32.35%, ADL 7.20%, Total sulphur 6.24%, heating value/BTU/lb 8617. Cholistan areas are significant and have vast areas for exploration and study of previous drilled holes if any for petroleum, water, etc. Further, in the west, Kingri-Aram-Gharwandi Coalfields (Latest Cretaceous coal), Kingri-Shikar-Tor Shah Coalfields (Early Eocene coal) and Toi Nala (Dewal-Ghoze Ghar-Savi Ragha) Coalfield (Early Eocene Toi Formation) have already described [5] [25] [28] . Further, the coal resources of area and surroundings were also reported [51] [52] [53] [54] . The drill hole log of Canteen area of Chamalang is shown in Figure 3 of [54] .

Petroleum resources: Petroleum are being produced from the Dhodhak oilfield/gas condensate field (northern part of Zinda Pir anticline) in Jurassic Chiltan Limestone [46] , Early Cretaceous Mekhtar, Goru and Parh formations (sandstone, marl and limestone), Late Cretaceous Mughalkot and Pab sandstones and Paleocene Rakhi Gaj sandstone and Dungan Limestone. Petroleum are also found in the drilled well of Savi Ragha and Jandran anticlines. The petroleum sources rocks like the Cretaceous Mughalkot and Sembar shales are widely found in Sulaiman foldbelt. The Mughalkot Formation have porcellaneous white to grey mudstone in the Rakhi Gaj and Girdu area which not seems to be sources of petroleum while in other areas it have blackish to grey and green shale which is significant for petroleum resources. Further, Mughalkot Formation acts as best host rocks because of shale and sandstone lithology, where shale is sources and sandstone act as reservoir rocks. That is the reason an oil spring found in Toi Nala of Mughalkot section. There are two Toi Nalas, one in the Mughalkot section and other southward located between the Toi Sar Thana area (Musa Khel) and Chitarwata area (Vihowa, Taunsa). The other major reservoir formations are Cretaceous Pab and Vitakri (as above), Paleocene Rakhi Gaj and Dungan, Habib Rahi and Pirkoh formation. The Rakhi Gaj Formation is well exposed in the eastern Sulaiman while in the west it has only shale deposits. Dungan Limestone is thin in the Mekhtar to Rakhi Gaj sections (poor reservoir), while it is thick in the north and also reasonable in the south (a good reservoir rocks). Habib Rahi and Pir koh limestones are relatively thin in the north (Drazinda and Domanda areas) and central (Rakhi Gaj area) and being increasing toward south especially in the Rajanpur areas and it is maximum thick at Dera Bugti areas and possibly in northernmost Sind Province. The Habib Rahi and Pirkoh being thick in the south can play significant role for the hosting petroleum reservoirs.

Radioactive mineral resources: Uranium can be explored from fluviatile cross bedded sandstones of the Oligocene-Pliocene Vihowa Group and Pleistocene to Holocene Sakhi Sarwar Group in Rajanpur, Dera Ghazi Khan and Taunsa areas. At present uranium is being exploited from the Miocene Litra sandstone in Dera Ghazi Khan and Taunsa areas. The uranium host Vihowa and Sakhi Sarwar groups traced along 200 km north south oriented outcrop along the Foot Mountains of Koh Sulaiman Range which host primary (uraninite, etc) and secondary (Tyuyamunite, carnotite, etc) uranium mineralizations. This significant uranium bearing rocks runs from Giandari (west of Rojhan) to Lundi Saidan to Sakhi Bor Bakhsh and Khaan (Rajanpur District) to Rakhi Gaj to Sorra to Fazla (Taunsa and Dera Ghazi Khan). Further, this host rocks can be found on the both limbs and plunges of Zindapir anticline. It may be explored in sandstones of Pab, Vitakri, Sangiali, Rakhi Gaj, Toi and Kingri formations in the Koh Sulaiman foldbelt. Iridium anomalies, REE and lithium can be tested in the Cretaceous-Paleogene boundary laterite, mottled muds and coal especially in the Fort Munro, Rakhi Gaj (and Kingri) and its vicinity areas.

Geothermal energy resources: Garmaf and Zinda Pir hot water springs of Taunsa area can be used for heating purpose during winter for nearby populations.

Forest resources and agricultural cultivation: The area is mostly barren of trees. Honourable Former Prime Minister Imran Khan Niazi started billion tree Project. Continuing this tree plantation and agricultural cultivation in barren lands and Daman areas of Koh Sulaiman Range and desert areas of Cholistan and Thal will shift the lands with greenery, rain will increase, pollution will decrease, weather will become better and income will increase which play major role for the development of these regions of Saraikistan area and ultimately for Pakistan.

Tourism: Fort Munro anticlinal peak areas from Mubarki to Hikbai to Fort Munro to Chitri to Dragal to Maarri belt can be used for tourism because of being elevated upto round about 7000 feet from sea level. Further, there are many mazars (tombs), forts and many other cultural heritages for tourism. Further, the locals and also foreigner can know and visit these tourism places and cultures. This tourism can play part of the development of the South Punjab and ultimately Pakistan.

Paleontology field museum and national and global geopark: Many famous paleontological sites fall in the Koh Sulaiman Range under the territory Taunsa, Dera Ghazi Khan and Rajanpur districts of South Punjab and adjoining Barkhan, Kohlu and Dera Bugti districts of Balochistan Province. These paleontological sites can be called as field museum of Cretaceous and also Cenozoic fauna and flora (see below). These sites are famous at international level because of discoveries of largest land mammals, largest marine mammals (walking to swimming whales), largest sauropods and theropod dinosaurs, mesoeucrocodiles, snake, pterosaurs and birds and other biotas. Many foreigner scientists like to work here. Their working here can be a source of foreign exchange. A Paleontological Museum should be established at Dera Ghazi Khan due to close occurrence of fossil host field sites. Further, the national and international visitors, researchers and scientists can visit and work easily at this museum and also can visit nearby field host sites. The shifting of fossils from field sites to museum will be relatively safe and breakage risk will be very low. Further, the Vitakri Dome of Barkhan District should be protected as National and Global Geopark because of being graveyard of latest Cretaceous biotas found just before the K-Pg Boundary extinction. This will save the destruction of exposed fossils, bones and host sites and horizon and will provide safe visits of national and international visitors.

South Punjab Secretariat and development-ease for peoples and Economic savings: Previous government lead by Former Prime Minister Imran Khan Niazi constructed the South Punjab Secretariat at Matital road, Multan and also at Bahawalpur. Further, make the functional South Punjab Civil Secretariat at Multan and Bahawalpur. Consequently, the transportation fuel, hoteling and other expenses were considerably reduced. Consequently ease of peoples of South Punjab started. Further extra burden on Lahore city and its pollution will be reduced. All these go to economic savings and the development of South Punjab and ultimately for Pakistan.

Water resources, smaller dams construction and energy resources: Rajanpur, D. G. Khan and Taunsa areas of South Punjab (Saraikistan) have vast potential of water resources because of mountainous areas with excellent topography, geomorphology and large catchment areas and also have downward vast barren plain but its needs proper preservation and increasing storage because significant portion wasted as flood. Storage as dams can also recharge the ground water of plain areas. South Punjab has mostly plain areas except north-south trended Koh Sulaiman Range. South Punjab has Indus, Chenab (include Jhelum river from Trimu and Ravi river from Sultan Baho/Garh More) and Sutlej (Source is Beas in Himachal) rivers. Sutlej and Chenab rivers join at Panjnand, and Chenab and Indus rivers join at Chachran/Kot-Mithan. These rivers got flood during summer after heavy rains. Koh Sulaiman Range has crossed numerous east-west trending streams/nalas/rudkohi which waste water as flood. Daman (foot-mountain) belt of Koh Sulaiman Range has vast barren lands more than 200 km north-south long and 10 - 30 km east-west wide. Here, smaller dams construction at mouth of streams like Kaura, Vihowa, Litra, Baathi, Kanwan, Sanghar (Sorra, Pachadhi and Poadhi Nalas of Manjhail/Kharar/Pir Gahno, Hinglun, Barthi/Hathi Mar), Luni, Drug, Sori-Zinda Pir, Dalana, Vidor, Mithwan, Rakhi Gaj, Khaan, Sakhi Bor Bakhsh, Kaha Harand, Chachar, Giandari and others can convert adjoining fertile barren lands into cultivation and greenery for sustainable development of South Punjab and ultimately for Pakistan. Further, these dams recharge the alluvial ground water resources which can be used during drought seasons. Honorable Former Prime Minister Imran Khan Niazi and Former Chief Justice Saqib Nisar initiated effort to start many large dams after previously long hibernation. On completion the peoples can get water for irrigation and cheap electricity, while previously thermal power plants run costly from coal (especially imported coal) and petroleum. Constructions of small water dams are vital due to congested and increasing population and large barren areas. Sutlej flood water should be diverted into Cholistan desert to increase the cultivation, drinking water and greenery for the development of poor local peoples. South Punjab has hot season best for solar energy and many large stream/ruds like Vihowa, Sanghar, Sori Zinda Pir and Kaha for small scale hydal energy via newly constructed dams to save costly thermal power supply and ultimately to reduce import of coal/petroleum which consequently save the foreign exchange. Coal, oil, natural gas, radioactive minerals, geothermal hot springs and geysers, etc. are exhaustable energy resources whilst solar, air/wind, terrestrial water, marine water/ocean, tides, waves, current, geothermal gradients of sea water, biomass, etc., are inexhaustable energy resources. Pakistan urgently demands the conversion of the non-conventional energy resources into those of conventional energy. Biomasses like crop residue (cotton stalk, wheat straw, rice husk), natural vegetation, trees, animal dung/manure and sewage are potential source of energy. These can be converted into energy by direct combustion and fermentation methods. The waste material is burnt in confined containers and heat is used for running boilers which produce steam to run a turbine generator. Biofuel like E-10 is a replacement of gasoline and can be produced by fermentation of biomass in digester tank by enzymes and decomposition in absence of air. Our global earth is receiving huge amount of energy from sun. Previously it was very expensive but now it is gradually becoming cheap. Nickel cadmium batteries can be used during night or cloudy days. The hydel energy is not sufficient due to increasing population; the development in construction of new dams and in solar energy is very necessary and vital in south Punjab and Pakistan.

History of discoveries of recently found biotas from Pakistan: The first ever bone of dinosaur from Pakistan was collected by MSM (present author) in early 2000. Later, on 100 bones/pieces of bones were collected with Philip D. Gingerich in Late 2000, pointing fossils on locality by MSM. About 1500 and 1200 bones/pieces of bones were collected by MSM during early and mid 2001, respectively. A large wood fossil and nautiloid were also collected by MSM. Many terrestrial bivalves were observed. The early history of discoveries of dinosaurs and other vertebrates during 2000 and 2001 were mentioned in detail ( [19] , pp. 108-109). About 400 recognized bones and a large wood fossil were published in series of papers [55] - [73] . Further walking whale fossils were collected during late 2000 under the supervision of Philip D. Gingerich [74] . Exploration and collection of titanosauriform 12 bones [6] [75] , a few vertebrates and invertebrates fossils [7] [65] [69] [70] and a sauropod footprint [3] [6] [7] [70] from Kirthar Range (lower Indus/south Indus basin) Khuzdar district, Balochistan were done in 2001-2003. Later on fieldwork conducted by MSM for dinosaur bone exploration during January, 2005 and March, 2005 in different sections of eastern Sulaiman foldbelt. Only a few fossils were also collected during this field work, while numerous bones observed in this field were left in the intact field place. Fieldwork conducted by MSM for dinosaur bone exploration from February-March, 2006 in Ziarat (Balochistan), Surghar (Mianwali District, Punjab) and Salt Range (Punjab). Footprints were also discovered during this field work [6] [7] [61] [68] [69] [70] [76] . All the localities of Balochistan and South Punjab (visited above) lie in the Sulaiman Range (middle Indus/central Indus basin) while Surghar and Salt Range lie in the Kohat and Potwar sub-basins (Upper Indus/North Indus basin), respectively ( [6] [7] and references therein). Further exploration and collection of about 100 basilosaurid fossil bones from middle Eocene Drazinda shale of Zamri area of Musa Khel District, Balochistan and 29 bones of large rhinoceros from Shagala area of Kamardin Kareez Tehsil, Zhob district and division was done in 2012-2013 [65] [69] [70] [77] . The exploration and collection of bones of large rhinoceros (Buzdartherium gulkirao) and crocodiles (Asifcroco retrai), and proboscidean (Gomphotherium buzdari) were done in 2013-2014 [6] [7] [65] [69] [70] . Footprints of late Cretaceous archosaurs from Sur Muzghai locality of Musafarpur, Qila Saifullah district, Zhob division, Balochistan was explored in 2013-2014 [6] [7] [63] [68] [69] [70] [71] . A footprint natural cast was discovered in 2018 from Maarri peak area of Rajanpur district, South Punjab [6] [7] [70] [78] .

Recently discovered fauna and flora from Pakistan: Recent paleontological exploration during 2000-2023 yielded 52 new biotas (mostly by me and in a few I was partially involved) from the Paleozoic, Mesozoic and Cenozoic strata of Pakistan (Tables 1-12). These prehistoric biotas include 3 fishes (Table 10), 31 reptiles (Tables 1-7 and Table 12), 9 mammals (Table 8 and Table 9), 1 bird (Table 10), 7 invertebrates (Table 11) and 1 plant (Table 10) [6] [7] . Round about 3000 bones/pieces of bones were collected from Vitakri Formation. Among these well recognized about 400 mostly large sized (with some medium and small sized) bones were documented so far, while the remaining mostly recognized about 800 mostly medium sized bones/pieces of bones and mostly non-recognized about 1800 small sized bones/pieces of bones were not documented so far. The small sized bones/pieces of bones (1800) and medium sized bones (800) belong to 25 localities of Vitakri dome, Mari Bohri plunge, Dhaola, Pikal and Fort Munro ranges. About 30 bones of central Alam skeleton are documented while more than 100 medium sized bones of this assemblage are not documented so far. The documented bones distributed as Titanosaurs 330, theropods 40, crocodilians 16, pterosaur 2, snake 7, bird 7, and mammal 1. The majority of the bones recovered from south, mid, north and top Kinwa, Mari Bohri, lower and mid Sangiali, Bor and Alam localities. The many bone assemblages and numerous bones observed in the south Sangiali (just above the mid Sangiali), Bor, Kinwa (south, mid, north and east/top Kinwa), Alam 19, east Alam 18 and Dada Pahi localities. Further excavations are promising here for yielding articulated and associated skeleton and complete bones.

The fishes found are Muzaffarabadmachli abbottabadi, Kahamachli harrandlundli and Karkhimachli sangiali [7] . The reptiles so far found are as below; poripuchian titanosaurs (mentioned as below), abelisaurian theropods (Shansaraiki insafi, Vitakridrinda sulaimani and Vitakrisaurus saraiki of Vitakrisauridae), crocodiles (Induszalim bala [6] and Pabwehshi pakistanensis [79] of Induszalimidae, Mithasaraikistan ikniazi of Mithasaraikistanidae and Sulaimanisuchus kinwai of Sulaimanisuchidae), Asifcroco retrai [6] [7] and Sakhibaghoon khizari [2] . Pterosaur—the flying reptiles (Saraikisaurus minhui [6] and Imrankhanuqab qaeddiljani—new genus and species (see below) of Saraikisauridae, and large paleosnake (Wadanaang kohsulaimani) [6] [7] , plesiosaur (the marine reptile) Zahrisaurus kilmoolai [7] . Mammals found so far are; possibly small mammal Mirvitakriharan haji [6] [7] based on posterior angular/dentary show close resemblance to Ausktribosphenids marsupial from Victoria (Figure 23(D) of [80] ), walking whales Artiocetus clavis and Rodhocetus balochistanensis [74] , swimming whale Sulaimanitherium dhanotri from Drazinda shale, and horse Hippomorpha Bolanicyon shahani, largest land rhinoceros (Buzdartherium gulkirao) and the Miocene Litra sandstone yielded the large proboscidean (Gomphotherium buzdari) [7] [65] [70] [77] . The Limb elements (GSP/MSM-RA-38-Taunsa to GSP/MSMRA-60-Taunsa; Figure 12 of [7] ) of Buzdartherium gulkirao (large rhinoceros) were collected and hosted by Rao M. Ayub (belongs to Gujranwala, previously mistyped Khoshab) of Pakistan Atomic Energy Commission, Taunsa (Dera Ghazi Khan). A paleobird (Wasaibpanchi damani of Wasaibpanchidae) [6] [7] was reported so far, however it may be possible the synsacrum articulated with pelvis of Imrankhanuqab qaeddiljani (see below) may belong to bird. Recently reported invertebrates [7] [65] [69] [70] are arthropods trilobite Moolatrilo chotoki, centipedes Nisaukankoil beakeri and Phailawaghkankoil derabugti and Echinodermata (star fish) Mulastar zahri; mollusks nautiloid Pakiwheel vitakri, Pakiwheel karkhi, and bivalve pelecypod Pakiring kharzani. The Late Cretaceous (Late Maastrichtian) Dhaola Member of Pab Sandstone yielded the large stem fossil of paleotree (Baradarakht goeswangai) [7] [65] [69] [70] .

Shansaraiki insafi Theropod: Shansaraiki is described by [11] but its best figures (Figure 2) and some description are provided here. The preserved medial side of dentary (GSP/MSM-5-3) has (preserved 2 teeth and one alveolus) consists of two large medial dental foramina (Figure 2). These foramina (located between two teeth) are large and more than 1 cm in diameter. These foramina approach to roots of teeth and used for nerve innervations and blood supply to dentary teeth, gums, muscles and tissues. These dentary foramina are among the autapomorphy of Shansaraiki insafi. Teeth are oval shaped and D-shaped asymmetrical (large size) to circular (medium sized). Large tooth have thick peripheral bone while small teeth show relatively thin peripheral bone while thickness vary in periphery. Further, teeth cavity of small and large teeth is almost same size. The teeth outer surface is wrinkled i.e. teeth outer bone periphery show long pipe type or hair type fibrous texture. The contact of teeth peripheral bone with core cavity is uneven and rough. The Shansaraiki insafi theropod dinosaur model (Figure 2, Row 3) was arranged by [81] . Shansaraiki insafi dentary from Pakistan has anterior weak symphysis closely match with dentary of Australovenator wintonensis from Australia [82] .

A new pterosaur (flying reptile) from the latest Maastrichtian Vitakri Formation of Pakistan and further evidence of avian/bird evolution from pterosaur:

Systematic paleontology

Pterosauria

Pterodactyloidea

Saraikisauridae [2]

Imrankhanuqabinae new subfamily

Definition: Imrankhanuqab; their most recent common ancestor and all of its descendants.

Included species: Imrankhanuqab qaeddiljani

Diagnosis: Imrankhanuqabinae is a subgroup of Saraikisauridae. It is more pneumatic than Saraikisaurinae. Further, Saraikisaurinae is edentulous during latest Maastrichtian which makes it unique. Diagnosis is same as genus and species Imrankhanuqab qaeddiljani (as below).

Imrankhanuqab qaeddiljani new genus and new species (Figure 2)

Holotype: Articulated synsacrum, left and right ilia and coosified spongy bony mass GSP/Sangiali-1175 (Figure 2) belongs to a single individual. Fossil is housed in the museum of Geological Survey of Pakistan, Quetta (but at present it is in Museum of Paleontology, University of Michigan, for preparation).

Etymology: Genus Imrankhanuqab established in honor of Imran Khan Former Prime Minister of Pakistan and Imran Riaz Khan distinguishing journalist of Pakistan for supporting the poor peoples and development of Pakistan especially Saraiki and Balochi Koh Sulaiman area which is host of fossils, uqab in Urdu and Saraiki languages for bird/eagle/falcon which are powerful and have high speed flight. In short it is uqab of Imran Khan. Imrankhanuqab pronunciation is Imran Khan Uqab. Species qaeddiljani established as, qaed in urdu and Saraiki languages for leaders (e.g., Dr. Shahbaz Gil, Habib Akram, Azam Swati, Shereen Mazari, Sanam Javaid, Khadija Shah, Dr. Yasmin Rashid, Irfan Hashmi, Shaheed Arshad Sharif, Waqar Malik, Haider Mehdi, Dr. Moed Pirzada, Sabir Shakir, Adv. Aitzaz Ahsan, Adv. Latif Khosa, Adv. Abdul Ghafar, Sami Abrahim, Sidique Jan, Prof. Dr. Shereen Sufyan Khan, Hisan Khan and others) for supporting poor peoples of the area, diljani in Urdu and Saraiki languages for sweat heart. Species qaeddiljani means the sweat heart leaders. Species name can be pronunciated as Qaed Dil Jani.

Type locality, horizon and age: Holotype was discovered in mid Sangiali locality (Figure 4 of [6] ), Barkhan District, Balochistan. The grid reference of type locality are latitude 29˚41'53.16''N; longitude 69˚23'55.39''E. The host horizon is the upper mud unit of Vitakri Formation of Fort Munro Group [6] [11] . Its age is the latest Maastrichtian [8] [9] [23] .

Diagnosis and comparisons: Imrankhanuqab qaeddiljani shares with Pterodactyloidea as heavily fused small sized synsacrum. Imrankhanuqab qaeddiljani shares with Saraikisauridae as pneumatic bones and adult large size agreement. Imrankhanuqab qaeddiljani autapomorphies are as below. It consists of synsacrum and articulated both left and right ilia (Figure 2). Synsacrum consists of heavily fused and coosified 7 preserved synsacral vertebrae. The cranialmost five synsacral vertebrae have distinct slender and narrow ribs/transverse processes/lateral processes. Anterior 5 synsacral centra are long and narrow while 6^th and 7^th synsacral centra are reduced and short. Caudal to the fifth synsacral centrum, the size of centra seems to be reduced rapidly toward the caudal terminus of synsacrum. While this feature is different than Muzquizopteryx coahuilensis [83] where caudal to third vertebrae the size of synsacral vertebrae reduced rapidly toward caudal terminus of synsacrum. The caudal segments comprising of 6^th and 7^th synsacral vertebrae of Imrankhanuqab qaeddiljani formed the richly spongy bony mass. Its anterior 5 synsacral ribs are extremely slender and narrow anteroposteriorly. The first vertebral synsacral rib is anterolateral directed while the second synsacral rib directed laterally, the third synsacral rib directed posterolaterally, the fourth synsacral rib directed toward almost lateral and the fifth synsacral rib is directed posterolaterally. The sixth and seventh synsacral ribs and also centra are fused. The rib of first synsacral is longest and then decreasing gradually posteriorly. The distal portion of synsacral ribs formed synsacrocostal yoke which is contacted laterally with left and right ilia. The sacricostal yoke (contact of sacral ribs and ilium) is maximum thick transversely at the level of 4^th sacral rib. It decreases anteriorly and also posteriorly forming asymmetrical arc shape (convexing medially and concaving laterally). This feature of Imrankhanuqab qaeddiljani matches with Coloborhynchus spielbergi [84] [85] . The posterior limb of this arc of Imrankhanuqab qaeddiljani is relatively more inclined outward than Coloborhynchus spielbergi [84] [85] which have almost subparallel to vertebral axis. The plate like bony mass (posterior part of synsacral) of Imrankhanuqab qaeddiljani is more wide and expanded transversely than Coloborhynchus spielbergi [84] [85] posterior bony mass. The four large apertures are found between the synsacral ribs of anterior and mid synsacral vertebrae. Then these apertures are being reduced as very small in distal synsacral vertebrae/plate like bony mass. Ilia are long. The ilium is arc shaped (convexing medially and concaving laterally. Ilium represents acetabulum just lateral to second synsacral. Fused spongy bony mass/bony plate is highly pneumatic. Bony mass is short anteroposteriorly and wide transversely, which is contacted laterally with ilium. Its synsacral vertebrae which are diminishing in anteroposterior length toward posteriorly, this feature matches with Pterodactylus which has diminishing vertebrae anteroposteriorly [86] . Its synsacral ribs are narrow and thin anteroposteriorly while the Huanhepterus quingyangensis [86] , Vectidraco daisymorrisae [87] and Coloborhynchus spielbergi [84] [85] have relatively thick anteroposteriorly sacral ribs/lateral processes. There are four large apertures between the synsacral ribs of Imrankhanuqab qaeddiljani while the Muzquizopteryx coahuilensis [83] has 2 large apertures, Huanhepterus quingyangensis [86] , Vectidraco daisymorrisae [87] , Anhanguera and Coloborhynchus robustus [87] have 3 large apertures and Coloborhynchus spielbergi [84] [85] have 4 large apertures. No any pterosaurs from India have synsacrum/sacrum for comparison.

Evidence of avian/bird evolution from pterosaur: The richly pneumatic and heavily fused synsacrum (Figure 2) with strongly thin and narrow synsacral ribs shows affinity to birds or evolutionary trend toward birds/aves. All the bones are pneumatic. Further, this coosified anatomy represents strong, powerful and speedy flight of Imrankhanuqab qaeddiljani. This fossil hosting strong coosified synsacrum with highly pneumatic bony mass (with articulated ilium) shows the early evolution of birds from pterosaurs. In this way, this can be expected as the Wasaibpanchi damani bird may be evolved from pterosaur Imrankhanuqab qaeddiljani.

A snout articulated with lower jaws and partial posterior of Gspsaurus and a snout articulated with lower jaws of Saraikimasoom, both these more advanced titanosaurs found from the latest Maastrichtian Vitakri Formation have no parallel in this age. Gspsaurus snout with V-shaped lower jaw is unique for Titanosaurian sauropods. Complete teeth rows of advanced titanosaurs are unknown so far while Saraikimasoom snout is unique anatomical wealth provide the dental Formula (4, 13/9-13). Rapetosaurus skull [88] material is disarticulated include incomplete maxilla. Nemegtosaurus [89] and Quaesitosaurus [90] skulls are older (not from latest Maastrichtian). Tupuaisaurus skull [91] is from Early Cretaceous. The first biconvex caudal of Balochisaurus and Marisaurus Balochisaurids from Pakistan matches with Pellegrinisaurus from Patagonia, Argentina and Alamosaurus from USA. The vertebrae and limb bones matches with both Gondwana and Laurasia showing Pangean distribution. The more stocky and transversely expanded proximal tibiae of Balochisaurus matches closely with late Jurassic Lusotitan atalaiensis from Portugal [92] and Late Cretaceous Lohuecotitan pandafilandi from Spain [93] and mid Cretaceous Diamantinasaurus matildae from Australia [82] . The robust tibia of Gspsaurus pakistani matches with Saltasaurus loricatus (Plates 45, 55 of [94] ). The slender flat proximal tibia of Khanazeem saraikistani and Sulaimanisaurus gingerichi matches with the Mendozasaurus neguyelap from upper Cretaceous of Medoza, Argentina [95] and Rapetosaurus krausei from the Late Cretaceous of Madagascar [96] and Igai semkhu from Egypt [97] . The large oval shaped ellipsoid (GSP/MSM-85-4) of Gspsaurus pakistani osteoderm from South Kinwa locality of Pakistan matches with large osteodermal ellipsoid of titanosaur (Plate 77 of [94] ) from Argentina, South America. The large oval shaped ellipsoid (GSP/MSM-84-7) armor bone of Balochisaurus malkani from south Zubra locality of Pakistan correlated with Malawisaurus [98] of Malawi. In short, the anatomy of Pakistani titanosaurs matches with Gondwana and Laurasian fauna showing Pangean distribution. Some elements of Pakistani titanosaurs are unique like the snouts of Gspsaurus and Saraikimasoom, and slender femora with inflected head of Pakisaurus and slender femora with concavity on proximolateral profile of Khanazeem, and diverse morphs of humeri.

The dentary of Pakistani theropod Shansaraiki insafi has anterior weak symphysis closely match with dentary symphysis of Australovenator wintonensis [82] from Australia showing affinity to Australian land of Gondwana but Savannasaurus sauropod [99] is contrasted having amphicoelous caudals while most of Pakistani titanosaurian are last most advanced Poripuchian titanosaurs which have procoelous anterior, mid, posterior and distal caudals. The Mesoeucrocodiles from Pakistan mostly matches with Brazil and Argentina (South America). Pterosaur from Pakistan matches with Asian and Gondwana showing global distribution (as shown above). However, the Saraikisaurus minhui, the edentulous pterosaur from the latest Maastrichtian of Pakistan is unique fossil in world. Some unique fossils are developed due to migration and isolation from other landmasses during Early to Late Cretaceous. Indo-Pakistan Plate was initially contacted with Asia/Eurasia at latest Cretaceous time which causes uplift and consequently the fluvial Vitakri Formation was deposited and terrestrial ecosystem evolved. Land bridges during latest Cretaceous formed on fluvial Vitakri Formation for land animals’ migration like Dera Ghazi Khan (South Punjab) to Vitakri-Sanjawi to Ziarat to Sor Muzghai Musafarpur to Sor Tangi of Sor Kach Zhob to Waziristan to Afghanistan and Asia. Second land bridge started from Amri-Bara (Jamshoro, Sindh) to Zahri Range (Karkh-Moola; Khuzdar) to Sor Range Quetta to Ziarat to Sor Muzghai Musafarpur to Sor Tangi of Sor Kach Zhob to Waziristan to Afghanistan and Asia. Due to these land bridges the well developed tracks and partial trackways of Ornithopaonia (and also Sauropaonia and Pteropaonia) are preserved on and around these land bridges [7] (Table 12). The close resemblance of partial and poorly recognized posterior dentary of Mirvitakriharan haji [7] [70] mammal from the latest Maastrichtian Vitakri Formation of Pakistan is found with the Early Cretaceous Ausktribosphenidae (Figure 23(D) and Figure 23(E) of [80] ) possibly placental mammals from Australia. Wasaibpanchi damani (member of Wasaibpanchidae) is a giant terrestrial bony toothed bird once ruled the skies of Indo-Pakistan subcontinent just before the K-Pg extinction [6] [7] . Early evolution of walking to swimming whale started from Eocene and Oligocene whale found from Tethyian deposited marine strata of Pakistan. The Eocene and Oligocene largest land mammals evolved from Pakistan and migrated toward Eurasia or may be vice versa. The Mesozoic fauna shows affinity to both Gondwana and Laurasia (Pangea), while Cenozoic mammals show link to Eurasia.
