| Abstract: | The paleodiet of Eucladoceros ctenoides (Nesti 1841), has been investigated on two sub-species from the Villafranchian fossiliferous sites of Saint-Vallier (Drôme, France), E. ctenoides vireti Heintz 1970, and Senèze (Haute-Loire, France), E. ctenoides senezensis Depéret 1910, using skull and mandible morphological features as well as the meso- and microwears methods. The validity of skull and mandible characters used to infer diet has been tested on extant cervid species: browsers (roe deer, moose and white-tailed deer) and mixed feeders at different level (Père David’s deer, fallow deer, chital, sambar, red deer and elk). The obtained results show that the Eucladoceros specimens from Saint-Vallier and Senèze shared paleodiet and ecologic niche. Cranial morphology and tooth wear are more similar to those characterising browsers than mixed feeders. Cranial morphology can be considered as a useful tool in inferring palaeodiets, in particular when tooth samples are too scanty to apply of micro- and/or mesowear analytic methods.Manuscrit reçu le 17 septembre 2003 Révision acceptée le 16 février 16, 2005 |
