Arctognathus is an extinct genus of gorgonopsid that throve during the Late Permian in the Karoo basin of what is now South Africa.[1]
Discovery

1886 illustration of a A. curvimola skull
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.[2]
Description
It was a small gorgonopsid with a total length estimated at 1.1 m and an 18 cm skull.[3]
