Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| D. Sigogneau-Russell 1995 | Molars with very high, narrow and trenchant crowns, with cusps b, a, and c subequal. Differs from all Triconodonta, and especially the Triconodontidae which have also subequal cusps, by their extreme trenchantness and deep separation, as well as by the absence of intermeshing between adjacent molars, suspectedly replaced by an overlap; differs also by cusp c slightly dominant. Cingulum faintly developed. |
