Inostrancevia is an extinct genus of carnivorous therapsids, containing the largest members of the family Gorgonopsidae, predators characterized by long, saber-tooth-like canines. The various species inhabited Northern Russia during the Upper Tatarian (Vyatskian),[1] a Russian regional stage equivalent to the Wuchiapingian stage of the Late Permian period, dating from approximately 260 to 254 mya. It is known from several skulls and two almost complete skeletons.
