Characteristics of these teeth compare well with those of extant Dasyatis teeth. Contrary to the illustration, it is most common for there to be a single central foramen with no lateral foramina on the lobes. The lingual face has a median ridge and concave lateral faces. The labial face has a pitted appearance resulting from numerous intersecting enameloid ridges. A transverse ridge is prominent, its lingual face having numerous labio-lingually oriented ridges.
Male teeth have a bilobate root with a high cusp.
They retain the pitted ornamentation on the labial face, but the labio-lingual ridges of the lingual face of the transverse crest are not present. This last characteristic is important when judging certain lateral and posterior teeth which may have a reduced cusp. On the labial face of the larger cusped teeth, there is often a median depression running down the cusp. This area may be ornamented with elongated enameloid ridges. Higher-crowned male variations have also been recovered.
