 Eutherocephalia is supported as a true clade in many phylogenetic analyses, but the placement of groups like Akidnognathidae, Hofmeyriidae, Whaitsiidae, and Baurioidea, all of which lie within Eutherocephalia, remains debated.The Eutherocephalians evolved several mammal-like traits through convergent evolution with the Cynodonts.Among those traits were the loss og palatine teeht and the reduction of the parietal eye.
