Abstract
New dental material of the late Miocene hyaenids, Percrocuta carnifex and Adcrocuta eximia latro, from the Siwaliks of Pakistan were excavated and described. These fossils with sound arguments testify the validity of both the genera described by Kretzoi, and followed by others. Moreover, they also shed light on the biogeographic and stratigraphic evidences of these species and genera (Percrocuta and Adcrocuta) from the Siwalik continental deposits.
