Oedaleops campi, an early synapsid

Oedaleops campi was an early member of Synapsida, a major evolutionary branch of amniotes that includes mammals and their close relatives. It lived during the early Permian, some 300 to 280 million years ago, in today’s New Mexico, United States.

O. campi was an approximately 30 cm (1 foot) long representative of a relatively large clade of early synapsids named Caseasauria. It was most closely related to Eothyris parkeyi from the early Permian of Texas, USA, with which it formed a group named Eothyridae.

In contrast to their closest relatives, bizarre plant-eating caseids, such as Casea and Cotylorhynchus, the eothyrids Oedaleops campi and Eothyris parkeyi had sharp, differentiated teeth, suggesting that these species were meat-eaters. Due to its position on the evolutionary tree, Oedaleops is a source of invaluable anatomical data concerning the early evolution of mammal-branch vertebrates – our ancestors.
