"I. vladimiri" Pravoslavlev, 1927"Inostrancevia" was a genus of
gorgonopsid therapsid found in Sokolki, on the SmallerNorthern Dvina River nearArkhangelsk inRussia . The animal lived 251million years ago during the LatePermian . The species "I. alexandri" is known from an almost complete skeleton missing some minor rib and vertebrae attachments.As with all other gorgonopsid species, it was a quadruped that had an upright posture of 1-4.3 metres long (as large as a bear), with a bone structure characteristic of strongmuscle attachments. The skull of 45 cm in length contained a smallereye socket and larger temporal opening than other less advancedtherapsids , like "Biarmosuchus tener". The teeth were quite large, the upperpalate containing 6 largeincisor s, 2 large canines and 10 smaller back teeth and themandible contained 6 large incisors and 8 smaller incisors.Gallery
