Diagnosis
ReferenceDiagnosis
B. L. Beatty and T. C. Cockburn 2015Dental formula is ?.1.2?.3/ ?.1.2?.3. Differs from Cornwallius, Paleoparadoxia, and Desmos- tylus in: molar cusps not in longitudinal rows nor closely appressed to each other. Differs from Cornwallius and Desmos- tylus in: molars that are brachydont and with cusps that retain spaces between them; molars retain labial and lingual cingula; molars, specifically M3, lack styles/stylids between the main cusps/cuspids. Differs from Behemotops and Cornwallius in: broad, flat mandibular symphysis that includes an enlarged canine tusk. Differs from all other desmostylians in: enlarged lower tusk almost rectangular in cross-section.
