Gspsaurus pakistani based on associated skull (with conical teeth tapering gradually from base to tip), vertebral and appendicular elements found from Alam 19 locality of Vitakri area, Barkhan district, Balochistan, Pakistan, South Asia. Gspsaurus bears sufficient skeletal elements and can be used for evolutionary studies.展开更多

Here the holotypic snout with articulated jaw bones and complete teeth row of Saraikimasoom vitakri are being presented which has international significance and contributes to understanding the evolutionary relationships and paleobiogeographic history of the vertebrates of Indo-Pakistan subcontinent. The completeness of the skeleton, in particular the presence of a well-preserved skull has a significant influence on resolution of titanosaur phylogeny. Here Saraikimasoom vitakri holotypic snout from South Kinwa, and referred jaw with articulated pointed and rounded teeth along with associated postcranial fossils from north Kinwa, and other associated materials from Mari Bohri, mid-Sangiali, Zubra Basti Nala and Grut localities of Pakistan are being presented. All these assemblages show consistent results.展开更多

Further titanosaur crania associated with postcrania are again negligible which prevented for its higher and lower level phylogenetic studies. The titanosaur skulls were also extraordinarily rare in Indo-Pakistan subcontinent, but the recent discoveries of holotypic skull, braincase and associated postcranial skeleton of Gspsaurus pakistani is anatomical wealth. Further its exemplar’ skeletons from Top Kinwa and Mari Bohri of Pakistan and Chota Simla from India provide more information which can be used for comparison. Here the holotypic partial skull with braincase and associated postcranial skeleton and also its exemplars and referred materials with key elements of Gspsaurus pakistani are being presented which have international significance and contribute to understanding the evolutionary relationships, higher and lower level phylogenetic studies and paleobiogeographic history of the vertebrates of Indo-Pakistan subcontinent.展开更多
