Other Megalocephalus fossils found in the 1860s had been referred to other large amphibians, namely Pteroplax and Anthracosaurus. Two well-preserved skulls and associated jaw bones were found in Newsham in 1870 and 1871, though these were also mistakenly referred to a pre-existing genus, Loxomma. In 1873, Thomas P. Barkas named a pair of new ...

Prionosuchus has been classified as an archegosaurid by Carroll. [6] The genus is monotypic with P. plummeri being the only species described. The archegosaurs were a group of temnospondyls that occupied the ecological niche of crocodiles and alligators during the Permian, and of which the European genus Archegosaurus is typical.
