Abstract

A new capitosaurid amphibian, Parotosaurus rajareddyi, from the Triassic Yerrapalli formation of the Pranhita-Godavari valley is described, and a restoration of the skull roof is given. General features of the skull, particularly the constricted otic notch, indicate that the new Indian species is perhaps more close to the Middle Triassic capitosaurids.
