Inostrancevia
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),[2] a Russian regional stage equivalent to the Wuchiapingian stage of the Late Permian period,[3] dating from approximately 259 to 252.3 million years ago. It is known from several skulls and two almost-complete skeletons.[4]
