Diet and dental morphology of two coexisting Aethomys species (Rodentia) in Mozambique. Implications for diet reconstruction in related extinct species from South Africa




The examination of dental morphology of coexisting modern Aethomys namaquensis Smith , 1834 and A. chrysophilus de Winton, 1896 from Mozambique, whose diet has been studied in the field, shows that the development of stephanodont crests and the multiplication of supplementary cusps on labial side of the lower molars is associated with a mainly vegetarian diet. To the most specialized dentition corresponds the most specialized diet. The application of these results to two coexisting Aethomys species from the fossil site of Langebaanweg (Pliocene, South Africa) allows to conclude that their dental differences correspond to different paleodiets.
