Eucynodontia ("true dog teeth") is a clade of cynodont therapsids including mammals and most non-mammalian cynodonts. The oldest eucynodonts are known from the Early Triassic and possibly Late Permian. Eucynodontia includes two major subgroups, Cynognathia and Probainognathia. [1]
Therapsids were synapsids that began to appear in the Early Permian. They had larger temporal fenestrae (openings of the sides of the skull) than the ancestral pelycosaurs . The most advanced therapsids are the cynodonts, which include mammals .
Eutheriodontia is a clade of therapsids which appear during the Middle Permian and which includes therocephalians and cynodonts, this latter group including mammals and related forms.
