摘要

Theropods, mesoeucrocodiles and pterosaurs (along with titanosaurian sauropods) are found in two overbank flood deposited mottled muds/shale units (alternated by meandering river deposited sandstone unit) of the latest Maastrichtian (67 - 66 Ma) Vitakri Formation, Barkhan District, Balochistan, Pakistan. These vertebrates coexisted under the Cretaceous-Paleogene boundary line of control and became extinct as mass extinction. Previously these taxa lack the detail description but here theropods, mesoeucrocodiles and pterosaur from Pakistan are being described well with large photographs which provide better understanding of fauna from Pakistan and comparison with coeval taxa from Indo-Pakistan subcontinent. These fauna with associated cranial and postcranial skeletons are significant for Gondwanan paleobiogeography and phylogenetic studies.
