Diagnosis
ReferenceDiagnosis
W. D. Matthew and J. W. Gidley 1904Dentition /3, /1, /4, /3. Molars without metaconid or entoconid. Premolars reduced, massive, crowded, without heel-cusps except on p4, and with no accessory posterior cusps. The dental formula and relative sizes of premolars and molars are as in Amphicyon, but the cusp composition of the molars is that of Cyon. All the teeth are very massive. The lateral incisor is exceptionally large. First premolar two-rooted.
