The Neotherapsida are a clade of therapsids. The clade includes anomodonts and the more derived theriodonts, which include mammals.

Distribution

Permian

In the Permian geological period, Neotherapsida lived in Germany , India , Madagascar , Niger, South Africa , Tanzania, United Kingdom , United States in Texas , and Zambia.

Severodvinian

In the Severodvinian age of the Tatarian stage of the Permian time period, Neotherapsida lived in Russia .

Triassic

In the Triassic, Neotherapsida lived in Antarctica, Argentina , Brazil , China , Germany , Lesotho, Morocco, Poland , Russia , South Africa , Tanzania, and United States in Arizona, Colorado, New Mexico, North Carolina, Texas , Utah, and Wyoming.

Jurassic

In the Jurassic time period, basal Neotherapsida lived in Lesotho.

Cretaceous

In the Cretaceous period, basal Neotherapsida lived in Australia and Russia .

Classification

The Neotherapsida were named and classified as a subgroup of the clade Eutherapsida by James Allen Hopson in 1999.

Taxonomy

Otsheria, an anomodont

Anomocephalus, a primitive anomodont that retained a full set of teeth

Aulacocephalodon, a dicynodont, a herbivore with two tusks

Kannemeyeria, a dicynodont, was one of the first large herbivores of the Triassic.
