Diagnosis
ReferenceDiagnosis
J. Morales et al. 2021the molars tend to
present a larger crushing surface, albeit displaying a dif-
ferent pattern with a greater mesiodistal length in the upper
molars and buccolingual length in the lower molars. This is
associated with a significant reduction of the carnassial teeth,
and loss of the p4 distal accessory cuspid. Dehmicyon n. gen.
is provisionally included as a basal form of this tribe
