Ophiodermatina is one of the two suborders of echinoderms belonging to the order Ophiacanthida. The suborder contains two superfamilies, which combine contain four families. It also contains five extinct genera. Fossils from this suborder have been found dating to the Late Carnian in Late Triassic.
