C. Stock 1936Upper incisors 2; teeth small, crowns oval and non-cingulate. Canines less robust than in Brontops. Small diastema between canine and P~. Premolars with well developed internal cingula, but no external cingula. Nasals long and broad. Horns larger than in Protitanotherium, oval in cross-section, but with transverse diameter greater, in relation to fore and aft diameter than in Uinta genus. Horns directed outward as well as upward. Dorsal surface of cranium narrow. Size large and intermediate between that of Protitanotherium emarginatum and that of Brontops robustus. This species is named for H. Donald Curry, discoverer of the first titanothere in the lower Tertiary of the Grapevine Mountains.
