Diploceraspis fossil map
Where fossils of Diploceraspis have been found, shown on the Earth as it looked about 300 million years ago and on today’s map.
Dots are fossil collections recorded in the Paleobiology Database. The “then” view moves today’s fossil sites back to their positions 300 million years ago (the time slice nearest the median age of the fossils) using the Merdith et al.

About Diploceraspis
Diploceraspis is an extinct genus of diplocaulid nectrideans. 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. 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. Other species include D. meritae from Nebraska and an indeterminate species from Oklahoma. Diplocaulus minimus of Late Permian Morocco may be of this genus.
