Brithopus is an extinct genus of dinocephalian therapsids. It contains a single species, Brithopus priscus, known from fragmentary remains found in the Copper

Sandstones near Isheevo, Russia.

Description

Brithopus was fairly large, reaching a length of 2.5–3 m (8–10 ft).{{cite web|url=http://palaeos.com/vertebrates/therapsida/anteosauria.html|title=Palaeos Vertebrates Therapsida: Anteosauria|website=palaeos.com|access-date=12 April 2018}} The skull was similar to Titanophoneus, but more massive and heavily built.Olson, E.C. (1962). "Late Permian terrestrial vertebrates, U.S.A. and U.S.S.R." Transactions of the American Philosophical Society, New Series, 52: 1–224.

Classification

B. priscus was first named in 1838 and was traditionally classified in the Anteosauria, a group of carnivorous dinocephalians. Brithopus served as the basis for the family Brithopodidae, which once included many anteosaurian species. Because it is based on fragmentary material, Brithopus is regarded as a nomen dubium by some researchers. Brithopus was later considered a possible estemmenosuchid,Kammerer, C. F. 2010. Systematics of the Anteosauria (Therapsida: Dinocephalia). Journal of Systematic Palaeontology, 9, 261-304. a type of herbivorous tapinocephalian therapsid.{{cite journal |last=Kammerer |first=C.F. |year=2011 |title=Systematics of the Anteosauria (Therapsida: Dinocephalia) |journal=Journal of Systematic Palaeontology |volume=9 |issue=2 |pages=261–304 |doi=10.1080/14772019.2010.492645|s2cid=84799772 }}

Dinosaurus and Eurosaurus have both been considered synonyms of Brithopus.Battail, B., and Surkov, M. V. (2000). "Mammal-like reptiles from Russia." The Age of Dinosaurs in Russia and Mongolia, 86-119.
