Sauroctonus

Sauroctonus is an extinct genus of therapsids.
"Sauroctonus progressus" was a large (2 m long) gorgonopsid that lived in the Late Permian epoch before the Permian-Triassic extinction event that wiped out many life forms on Earth (259-254 million years ago). Its fossils have been found in the Usili Formation (Songea Group) of Tanzania and the Sokolki Assemblage Zone of the Volga Basin of Russia.
"Sauroctonus's" flattened, triangular skull was about 25 centimeters long, with a parietal eye, a primitive character, on the crown. The upper and lower jaw each contained one pair of massive canine teeth (the upper pair was larger); the other teeth were smaller, but were also sharp and pointed. In addition, minute, blunt teeth were present on the palatine bones. The lower jaw was widened to form a kind of chin. The long, lightly built, five-toed limbs bore a resemblance to mammals' limbs, but despite its 'mammalian' characteristics, "Sauroctonus" was not one of the ancestors of mammals. Based on its cranial and skeletal features, "Sauroctonus" was not as specialized as other gorgonopsids such as "Rubidgea" or "Inostrancevia".
Species.
There are two recognized species of "Sauroctonus": "S. progressus" and "S. parringtoni".
