The Diploceraspis is a genus of lepospondyl amphibian, a type of early tetrapod. As a lepospondyl, the Diploceraspis likely had spool-shaped vertibrae that grew as bony cylinders around the notochord.

The Diploceraspis very closely resembles the Diplocaulus, though they differ in size, with Diploceraspis measuring smaller.

The Diploceraspis was originally recognised as two species: D.burkei and D.conemaughensis. However, this was proven inaccurate due to the size range overlap.

Diploceraspis lived in North America during the Permian period, which was the last period of the Paleozoic Era.
