The Probainognathians

The Probainognathians are members of one of the two major clades of the infraorder Eucynodontia, the other being Cynognathians. The earliest forms were carnivorous and insectivorous, though some species eventually also evolved herbivorous traits. The earliest and most basal Probainognathian is Lumkuia, from South Africa. Three groups survived the extinction at the end of Triassic; the Tritheledontidae and Tritylodontidae, who both survived until the Jurassic - the latter possibly even into the Cretaceous (Xenocretosuchus), and Mammaliaformes, who gave rise to the mammals.[1]
