They were the major predators of their day. They had large, powerful, square-shaped jaws with huge, sabre-like canine and interlaced, socket-like teeth. Many fossils have been found in South Africa.

The Gorgonopsidae are divided into three sub-families:
- Rubidginae, which had large, broad skulls,
- Gorgonopsinae, which included most of the gorgonopsid genera.
