Diagnosis
ReferenceDiagnosis
P. M. Butler 1984Differing form Rhynchocyon as follows:-Oblique crest (anterior hypoconid crest) on lower molariform teeth ends midway between protoconid and metaconid, instead of joining the metaconid; metastylid absent on dP/4 and M/1; paraconid of P/4 and M/1 higher and more lingually situated; cheek teeth more brachydont; anterior margin of ascending ramus more upright. The skull, known only in M. clarki, has primitive characters (Butler & Hopwood 1957).
