Moschognathus

Extinct genus of therapsids that lived in the Guadalupian epoch

Moschognathus is an extinct genus of dinocephalian therapsid in the family Tapinocephalidae. The genus includes only the type species M. whaitsi, named by palaeontologist Robert Broom in 1914. It was a short-snouted tapinocephalid, closely related to and resembling the well-known genus Moschops, but its skull is less thickened overall has a relatively longer and shallower snout by comparison. Indeed, Moschognathus has typically been regarded as a junior synonym of Moschops since 1969 after Lieuwe Dirk Boonstra sunk Moschognathus into Moschops, albeit retained as its own doubtfully valid species. However, researchers in the 21st century have expressed doubt over this synonymy and suggested that Moschognathus is a distinct taxon after all, including first by Christian Kammerer in a 2009 Ph.D. thesis and formally in 2015 by Alessandra D. S. Boos and colleagues in 2015. Moschognathus has since began to re-enter scientific literature of dinocephalians as a valid name and treated distinct from Moschops.
