Pabwehshi (meaning "Pab [Formation] beast ["wehshi" in Urdu]") is an extinct genus of sebecian mesoeucrocodylian. It is based on GSP-UM 2000, a partial snout and corresponding lower jaw elements, with another snout assigned to it. These specimens were found in Maastrichtian-age Upper Cretaceous rocks of the Pab Formation in Balochistan, Pakistan, and represent the first diagnostic crocodyliform fossils from Cretaceous rocks of South Asia. Pabwehshi had serrated interlocking teeth in its snout that formed a "zig-zag" cutting edge. Pabwehshi was named in 2001 by Jeffrey A. Wilson and colleagues. The type species is P. pakistanensis, in reference to the nation where it was found.[1] It was traditionally classified as a baurusuchid closely related to Cynodontosuchus and Baurusuchus.[2][3][4][5] Larsson and Sues (2007) found close affinity between Pabwehshi and the Peirosauridae.[6] Other studies such as Sereno et al. (2009) and Montefeltro et al. (2011) separate Baurusuchus, Cynodontosuchus, and other closely related genera from Pabwehshi, placing Baurusuchidae within Notosuchia.[7][8] Pabwehshi is placed outside Baurusuchidae and Notosuchia all together.
