Diagnosis
ReferenceDiagnosis
D. R. Prothero 2009argest species of Perchoerus (ml-3 length = 44-49 mm); distinguished from P. minor by its larger size; distinguished from P. nanus by its much larger size, slightly larger cheek teeth, much larger M3 with a enlarged metacone and posterior cingulum, and longer m3 hypoconulid with more complex cusp patterns; distinguished from Thinohyus by its relatively brachycephalic, less robust skull, lacking diastemata.
