UA 8653, the holotype, is hypsodont and curved. It is 11.2 mm high, of which the crown makes up about 85%, and the dimensions of its crown are 3.4 x 3.2 mm. The occlusal (chewing) surface is worn flat and contains a V-shaped island of dentine surrounded by enamel. One side of the crown lacks enamel. Between the two arms of the V, at the lingual (inner) side of the tooth,Wilson et al., 2007, p. 526 is a furrow filled with cementum, which extends all the way through the tooth; the presence of such a long furrow distinguishes it from Gondwanatherium. The enamel is made up of small, round prisms (bundles of hydroxyapatite crystals) that are separated by large, continuous bands of interprismatic matrix (IPM; the material between the enamel prisms).
