Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| P. M. Velazco and M. J. Novacek 2016 | Leptictids with large, distinct hypocones on P5 (vestigial or absent in nonleptictines). Anteroposteriorly more elongated P5 and upper molars with lower para- cones, protocones, and metacones (taller cusps in nonleptictines). Upper molars with slightly more labially situated conules, absence of a twinned paraconule, and variably developed ecto- exi, but less deeply infolded than in nonleptictines. Upper molar parastylar spurs poorly developed. Elongated p5, with large, projecting paraconid. Skeletons (known in Leptictis dako- tensis and Palaeictops matthewi) with distinct distal fusion of tibia and bula, head of humerus semilunar with sharply de ned medial border, head of femur strongly canted to long axis of sha , and deep trochanteric fossa of femur. |
