Oedaleops campi (Langston 1965) Asselian, Earliest Permian ~295 mya, ~7 cm skull length, was derived from a sister to Romeria? primus and was a sister to Eothyris and Casea in a clade that also included Milleretta RC70.
Distinct from Romeria? primus, the skull of Oedaleops had a flatter shape with a larger naris and a descending jugal, as in Concordia. The pineal opening was relatively very large. The maxilla was deeper. A large lateral temporal fenestra embayed the jugal and squamosal. The teeth were elongated, as in Concordia and Cephalerpeton.
