Diagnosis
ReferenceDiagnosis
E.G. Kordikova and H. de Bruijn 2001Upper molars: the anterocone of the M1 is divided into two cusps of equal size, lingual and labial branch of the anteroloph of the M2 well developed and of about the same length. The labial spur of the anterolophule and the mesoloph of the M are usually long and reach the labial side of the occlusal surface. M2 with double protolophule and often double metalophule. Mesoloph of the M2 long and independent of the double connections between the lingual and labial cusps. M3 small and rounded.
Lower molars: the anteroconid of the m1 is a single cusp. Shape of the occlusal surface of the m1 sub-triangular, less elongate than in typical Megacricetodon and in most primitive myocricetodontines. The mesolophids of the m1 and m2 are usually long and often reach the lingual border of the occlusal surface.
