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. It inhabited Northern Russia during the Upper Tatarian (Vyatskian),[1] a russian regional stage equivalent to the Wuchiapingian stage of the Late Permian period,[2] dating from approximately 260 to 254 mya. It is known from several skulls and two almost complete skeletons.

Etymology
Inostrancevia was named by the Russian paleontologist Vladimir P. Amalitsky[4] in honour of the Russian geologist Aleksandr Inostrantsev.

Discovery
The first fossils were found in the Sokolki Assemblage in the Oblast of Arkhangelsk[1] as part of the Northern Dvina River excavations lead by Amalitsky during the end of the 19th century. Two nearly complete skeletons were found alongside several other skeletal remains, one of which was mounted and exhibited in Saint Petersburg in 1900 with the other following a few years later. Proper descriptions of the findings were published posthumously in 1922.
