Therapsid subfamilies

Rubidgeinae is an extinct subfamily of gorgonopsid therapsids known only from Africa. They were among the largest gorgonopsians, and their fossils are common in the Cistecephalus and Daptocephalus assemblage zones of the Karoo Basin. They lived during the Late Permian, and became extinct at the end of the Permian.

Gomphodontosuchinae is a subfamily of Triassic traversodontid cynodonts. It includes the genera Gomphodontosuchus (the type genus), Exaeretodon, Santagnathus, Siriusgnathus, Menadon, Proexaeretodon, Protuberum, Ruberodon and Scalenodontoides.

Syodontinae is a group of dinocephalian therapsids. It is one of two subfamilies in the family Anteosauridae, the other being Anteosaurinae. 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.
