Eutheriodontia
Eutheriodontia refers to all theriodonts except the gorgonopsians. They included the therocephalians and the cynodonts. While the monophyly of Theriodontia as a whole is not certain, Eutheriodontia has been strongly supported as a clade, with the cynodonts being either a sister group to the therocephalians or evolving from within them. The cynodonts include the mammals. The eutheriodonts have larger skulls, accommodating larger brains and improved jaw muscles.
