Gorgonops

Gorgonops (literally "Gorgon' face") is the name given to an extinct genus of therapsid which lived about 255-250 million years ago, during the latest part of the Permian period. It was a typical representative of the Gorgonopsia, the dominant predators of their day, which in the largest forms grew to over four meters long.
