Diploceraspis is an extinct genus of lepospondyl amphibian. It lived in North America during the Permian period. It closely resembles its relative, Diplocaulus. It generally sports the same features as Diplocaulus, though it was smaller, measuring over 46 cm.^[1] Beerbower originally recognised two species, D.burkei and D.conemaughensis, but they are no longer regarded as being distinct from one another as their size ranges were found to overlap.^[2] Other species include D. meritae from Nebraska and an indeterminate species from Oklahoma.^[3]
