Osteichthyes - Anguidae

Taxonomy

Its type specimen is YPM 541, a partial skeleton (frontals (lectotype), 3 lower jaw fragments, partial right maxilla, pterygoid, scutes and bone fragments), and it is a 3D body fossil. Its type locality is Grizzly Buttes, which is in a Bridgerian terrestrial horizon in the Bridger Formation of Wyoming. It is the type species of Xestops, Oreosaurus.

It was recombined as Xestops vagans by Marsh (1873), Hay (1902), Hay (1930), Meszoely (1970), Zonneveld et al. (2000).

Synonyms

Dimetopisaurus wyomingensis was named by Hecht (1959). Its type specimen is AMNH 3819, an other (left frontal), and it is a 3D body fossil. Its type locality is Hyopsodus Hill, which is in a Bridgerian terrestrial horizon in the Bridger Formation of Wyoming. It is the type species of Dimetopisaurus.

It was synonymized subjectively with Xestops vagans by Meszoely (1970).
