These teeth are unilaterally hypsodont and typically lophodont, with flat grinding surface, but with neither an anterior extra ridge nor a syncline Ia on the upper molars. The mid-ridges/synclines are distinctly inclined (with a mesial angle to the longitudinal axis being generally 55° to 70° on the upper molars and 45° to 60° on the lower molars). Synclines I, II and III on the upper molars, and synclines II, III and IV on the lower molars are buccally open. The endoloph is developed, but is interrupted by syncline II, while the endolophid is continuous. The upper molars have 3 roots each, and the lower molars are two-rooted.</paragraph>
