Datheosaurus is an extinct genus of caseasaur. It was at least 1.5 metres (5 ft) in length. It lived during the Latest Carboniferous to Early Permian in Poland.

Discovery and history

It was originally described in 1905 on a basis of a specimen from late Carboniferous deposits in Poland.[1] It was later considered a synonym of Haptodus by several authors, but subsequent examination has found it be a caseid rather a sphenacodont.[2] This was confirmed by cladistic analysis, which recovered Datheosaurus as a basal caseid[3]
