Inostrancevia reconstruction

This is my best shot at a Inostrancevia reconstruction. Just a sketch, I'll color it later.

They are officially recognised as mammal-like reptiles, although more and more they are being considered as reptile-like mammals, due to the large number of mammalian adaptations, and very few remaining reptile-like traits.
Gorgonopsians are a part of a special group of therapsids called theriodonts, which includes mammals. They were among the largest carnivores of the late Permian. The largest known, Inostrancevia, was the size of a large bear with a 45 cm long skull, and 12 cm long sabre-like teeth (clearly an adaptation to being a carnivore). It is unknown whether they had fur, scales, or naked skin.

Inostrancevia was a genus of gorgonopsid therapsid found in Sokolki, on the Smaller Northern Dvina River near Arkhangelsk in 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.

As with all other gorgonopsid species, it was a quadruped that had an upright posture of 1-4.3 metres long, 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.
