Arctognathus is an extinct genus of gorgonopsids that throve during the Late Permian in the Karoo basin of what is now South Africa .[2]
Discovery
A carnivore, like all gorgonopsid, Arctognathus was given its name ("Bear jaw") in reference to its short and rounded snout. There is only one recognized species, A. curvimola.[3]
Description
It was a small gorgonopsid with a total length estimated at 1.1 m and an 18 cm skull.[4]
