Abstract

The variability of one of the oldest known proboscideans, Numidotherium koholense from the Lower Eocene of El Kohol, Algeria, is here examined. The biometrical study of the jugal teeth shows that the population is homogeneous and corresponds to a single species. The important variations of the skull's shape are interpreted as resulting from sexual dimorphism. The dental variability is analysed and discussed from an evolutionary perspective regarding the adaptative radiation of the proboscidean order at the beginning of the Tertiary.
