Isolated teeth of Glikmanius occidentalis occur in ten vertebrate faunas in the Waggoner Ranch Formation and in one fauna in the underlying Petrolia Formation. They range in size (anteromedial-posterolateral base length) from 1.28 mm to 10.15 mm (n = 12). In addition to the typical teeth, one with an asymmetrical base and one possible posterior tooth (both G. ?occidentalis), and a questionable symphyseal tooth (Glikmanius?), occur in the collection.
