Its type locality is Archer City Bonebed 1 (Putnam Fm.), which is in a Wolfcampian terrestrial horizon in the Archer City Formation of Texas. It is the type species of Poliosaurus.

It was recombined as Poliosaurus uniformis by Case (1907), Hay (1930), Romer (1936); it was recombined as Ophiacodon uniformis by Romer and Price (1940), Reisz (1986).
