What is "gorgonops"

Gorgonops (from Greek Γοργών -Gorgon- and ὤψ -eye, face-, literally " Gorgon' eye" or " Gorgon' face") is an extinct genus of therapsid which lived about 260-254 million years ago, during the Late Permian. It was a typical representative of the suborder Gorgonopsia, the dominant predators of their day, which in the largest forms grew to over three metres long.
