Anteosauridae is an extinct

therapsids that are known from the Middle Permian of Asia, Africa, and South America.These animals were by far the largest predators of the Permian period, with skulls reaching 80 cm in length in adult individuals, far larger than the biggest gorgonopsian
.

Description

Life restoration of Archaeosyodon

Anteosaurids are characterized by very large pointed incisors and canines, bulbous spatulate (spoon shaped) postcanines, a very strongly upturned margin of the premaxilla, so the front of mouth curves strongly upwards, and a long, very robust lower jaw (Boonstra 1963).

Anteosaurids distinguished from

Doliosauriscus and Anteosaurus, not only was this boss very prominent, but the bones were very thick and rugose. The same situation is found in the herbivorous Tapinocephalidae
, and it has been proposed that these animals engaged in head-butting behaviour. (Hopson & Barghusen 1986)
