Dental variation in the genus Pan.

Dental measurements and 23 anatomical dental features are observed on 151 Pan troglodytes and 69 Pan paniscus of both sexes, preserved in the Museum of Tervuren (Belgium). Odontometric investigations confirm the reality of the two species in the genus Pan, but do not show any difference between subspecies in Pan troglodytes. Correspondence analysis demonstrates that the qualitative anatomical features are differently distributed in the two chimpanzee species.
