Syodontinae is a group of dinocephalian therapsids. It is one of two subfamilies in the family Anteosauridae, the other being Anteosaurinae.^[1] They are known from the Middle Permian Period of what is now Russia and South Africa. One of the best known syodontines is Syodon from Russia. The South African form Australosyodon, is one of the earliest known Gondwanan anteosaurs.

Description

Syodontines lack the boss on the lower jaw that characterises the related anteosaurines, and they have often been considered more primitive in this respect.
