Saraikimasoom vitakri is a very small sized stocky sauropod sharing with Titanosauria as procoelous caudals (except first biconvex caudal); forward insertion of neural arches on caudals, prominent olecranon process on ulna and vertebrae lacking hyposphene-hypantrum articulations. Saraikimasoom vitakri autapomorphies are very small sized spongy skull dorsal profile inclined moderately or 40˚ from horizontal; skull without anterior step; low angle palatine; premaxillary canal is reversely triangular and high angled V shaped; conical teeth converge and taper gradually from base of crown to tip; teeth are small, circular and slightly recurved: upper and lower U shaped teeth rows; dentary ramus anterior depth is slightly more than dentary at mid length: dentary with narrow anteroposteriorly symphyses; anterior dentary rounded (no chin or very small chin); dentary symphysis, perpendicular to axis of jaw ramus; dental formula 4, 13/9-13?; small braincase with sub rectangle shaped basioccipital condyles angles 120˚ (from skull roof) toward posteroventrally; Braincase has a prominent supraoccipital wedge and proatlantal facets; ventrally reduced broad caudals; trispinous distal caudals; and subcircular proximal tibia with equal anteroposterior and transverse width.

Very small sized skull interlocked with dentary is highly spongy. Its upper profile inclination is 40˚ from horizontal. It preserved cross section which shows ventral and dorsal palatal processes. Lower and upper teeth row anteriorly formed U-shaped (unlike Gspsaurus which have lower teeth row V-shaped). Teeth are circular to subcircular, relatively small, slightly recurved and conical-taper gradually from base to tip and tooth slenderness indices vary from 3 - 5.

Rostrum dorsal profile dorsoanteriorly inclined moderately 40˚. Skull is very small sized and highly spongy. Rostrum has no anterior step on premaxilla. Teeth are inserted on anterior and lateral rostrum (unlike diplodocoids). Low angle, broad reversed V-shaped palatal, and V-shaped dorsal palatal hook, each limb attached on the contact of maxilla and premaxilla. Palatal maxillary and premaxillary canals occurred. Dentary ramus anterior depth is slightly more than dentary at mid length. Dentary has short or narrow anteroposteriorly symphyses. Dentary symphysis angled 70˚ or more anteriorly to axis of jaw ramus. Anterior Dentary rounded (feeble chin or no chin). External nares retracted posteriorly. Eye situated posteroventrally to the external nares. Premaxillary mid line contact is prominent. Small braincase with sub rectangle shaped (unlike Indian braincases) basioccipital condyle. Cervical centra are broad. Cervical and dorsal centra are opisthocoelous. One dorsal centrum has bony septa in pleurocoel and pleurocoel is divided, while others have no bony septa (Gspsaurus have bony septa in axis centrum pleurocoel). Long dorsal centrum has deep pleurocoel with thick lip. Sacral centra are short, broad, pneumatic and have a ventral keel. All caudal centra are procoelous except first caudal. First caudal is biconvex, broad and long (while Gspsaurus has ball like). Anterior caudal centra are broad and have separated transverse process and did not extend to neural arch (except first caudal). Middle caudal centra ventrally reduced. Posterior ball of distal caudal centra is not restricted (unlike Gspsaurus restricted posterior ball). Trispinous distalmost caudal centrum, two oval shaped spines extend posteroventrally or posterodorsally and one spine upward or downward. Proximal humerus lateral limb is longer than medial limb. Distal Humerus has anteriorly expanded radial condyle. Pubis has small articular surface for ilium peduncle and large acetabular glenoid. Ischium has low and not expanded articular surface for ilium peduncle, followed by long glenoid and then area for pubis attachment. Ischium is thin and plate. Proximal femur is non-deflected. Distal condyles are strongly expanded with rugosities extended on medial and lateral sides. Subcircular proximal tibia has equal anteroposterior and transverse width. Astragalus, a synclinal fold type with both limbs and central depression. First mosaic type armour bone and second false jaw ramus type with embedded teeth type spikes as osteoderms and third large oval plate may be osteoderm or ungual.
