Eucynodontia
Clade of cynodonts
From Wikipedia, the free encyclopedia
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]

The clade was named in 1982 by Thomas Kemp, who defined it as all cynodonts more derived than Thrinaxodon.[2][3]
In 2001, Hopson and Kitching redefined the clade Eucynodontia as the least inclusive group containing Mammalia and Exaeretodon.[4]
