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.

With the dicynodonts, they form one of two lineages of therapsids that survived the End-Permian extinction and which diversified again during the Triassic, before the majority of them disappeared before or during the Triassic–Jurassic extinction, except for a lineage of cynodonts that later gave rise to mammals.

Classification

The clade was named in 1986 by

Mammalia and Bauria.^[2] Even today, the taxon has a strong recognition among paleontologists and is regularly cited in several studies concerning therapsids.^[3]

Evolutionary history and characteristics

The therocephalians and cynodonts are thought to have diverged in the

temporal openings.^[4]
