Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. Freudenthal 1996 | Eucricetodontinae of very small to medium size, with relatively low/crowned cheek teeth, with thin enamel, relatively small cusps, and long crests. Lower molars with or without hypoconid hind arm. m1 with protoconid hind arm frequently connected to the metaconid. Upper molars generally with a posterior protolophule and an anterior metalophule. M1 generally without a complete anterolophule. Old entoloph on M3 frequently present, or even complete, neo-entoloph fully developed. |
