Unworn teeth of Hypolagus brachygnathus Kormos (Leporidae, Mammalia)
Abstract:
The author gives detailed description and morphological analysis of the early growth stages of permanent cheek teeth of the fossil leporid Hypolagus brachygnathus Kormos. Unworn cuspid teeth are compared with those in some recent leporids and ungulates. It was possible to establish the probable homology only of the central and two lateral cusps in upper cheek teeth of Hypolagus brychygnathus and recent leporids. Some facts against the hypothesis of the relationship between lagomorphs and ungulates are discussed and emphasized.
