Diagnosis
ReferenceDiagnosis
B. L. Beatty and T. C. Cockburn 2015Dental formula is 3.1.2?.3/3? 1.2?.3. Differs from Cornwallius in: having three pairs of upper incisors; molar cusps not in longitudinal rows, not columnar, and not closely appressed to each other, but are brachydont and retain spaces between them; molars retain labial and lingual cin- gula; upper molars, specifically M3, lack styles/stylids in between the main cusps/cuspids; coronoid process of mandible is more strongly posteriorly inclined. Differs from Paleoparadoxia in: incisors not enlarged and flattened; incisor arch not flat or straight; molar cusps not in longitudinal rows, columnar, or closely appressed to each other; postorbital process of jugal pres- ent, but not articulating with a dorsally expanded zygomatic pro- cess of the squamosal. Differs from Desmostylus in: having three pairs of upper incisors; molars brachydont; postorbital process of jugal not contacting zygomatic process of squamosal because the latter is not dorsoventrally expanded.
