Phylum: Chordata
Class: Amphibia
Genus: Eupelor

Eupelor is a dubious genus of prehistoric amphibian belonging to the temnospondyl family Metoposauridae. Fossils have been found in present-day Pennsylvania dating to the late Triassic.

Taxonomy

The Eupelor type species, E. durus, was named Mastodonsaurus durus by Cope (1866) on the basis of AMNH 3927, a number of clavicles, from the Lockatong Formation of Phoenixville, Pennsylvania.[1] Cope (1868) allocated the species to its own genus, Eupelor, based on differences from Metoposaurus (then known as Metopias).[2]

Colbert and Imbrie (1956) reviewed all Triassic metoposaurids and concluded that Eupelor should be used for all metoposaurids from North America, especially Koskinonodon. The authors considered the trematosaur Calamops a possible synonym of Eupelor.[3] Later, Chowdbury (1965) subsumed Eupelor into Metoposaurus along with other North American netoposaurids.[4] Hunt (1993), however, treated Eupelor as a dubious genus of metoposaurid due to its non-diagnostic nature.[5]
