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]
