Leporidae

Reconstruction of Hypolagus, from here.


Belongs within: Lagomorpha.
Contains: Leporinae.

The Leporidae includes the rabbits and hares, small to medium-sized herbivorous mammals with generally elongate ears and feet. Early representatives include the Late Miocene to Early Pleistocene Hypolagus which first appeared in North America before dispersing to Eurasia and differed from more derived forms in retaining only a single anterior reentrant on the second upper premolar. The Notolagini are a North American Pliocene to Pleistocene group with a deep anterointernal reentrant on the third lower premolar (Averianov 1999).

Synapomorphies (from Averianov 1999, for crown-group excluding Hypolagus): P2 with three or more reentrants; M3 reduced, width <40% of width of M2; p3 with both posteroexternal and posterointernal reentrants present.
