Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. Freudenthal 1994 | The molars have massive cusps and narrow valleys. The anterior metalophulid of m1 is frequently absent. The protoconid hind-armis moderately developed in m1, rarely present in m2, and absent in m3. The ectolophid of the m1 is oblique. In M1 the lingual anteroloph often forms a continuous high crest, that reaches the antero-labial tip of the protocone; the metalophule is connected to the center of the hypocone or farther backwards. The sinus of M1 and M2 falls down steeply from the entoloph to the molar border, and has no horizontal part. In M3 the sinus is often very deep, the old entoloph being connected to the anterior part of the protocone, and the neo-entoloph being low or absent. |
