YakThe domestic yak (Bos grunniens) is a long-haired domesticated bovid found throughout the Himalayan region of the Indian subcontinent, the Tibetan Plateau and as far north as Mongolia and Russia. It is descended from the wild yak (Bos mutus). Inostrancevia alexandriInostrancevia is a genus of gorgonopsid therapsid found in Sokolki, on the Smaller Northern Dvina River near Kotlas in Arkhangelsk Oblast, Russia. The animal lived 251 million years ago during the Late Permian. The species I. alexandri is known from an almost complete skeleton missing some minor rib and vertebrae attachments. t was the largest of the gorgonopsids, weighing 500-1000 pounds and measuring 4.3m long (about the size of a large bear). It's skull measured 45 cm long and it had two 12cm long saber teeth that it used to dispatch enemies and prey. 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 strong muscle attachments. The skull of 45 cm in length contained a smaller eye socket and larger temporal opening than other less advanced therapsids, like Biarmosuchus tener. The teeth were quite large, the upper palate containing 6 large incisors, 2 large canines and 10 smaller back teeth and the mandible contained 6 large incisors and 8 smaller incisors.
