Abstract : In Bourdette, if evidences of cave bear occupation are omnipresent (in the form of bones, claw marks and beds), the cave also delivered remains of more than a dozen other species as well as some lithic artifacts. Such a combination of different materials cannot be fully explained by the sole function of the cave as a bear den. In order to distinguish the different types of occupations in Bourdette and to establish their chronology, this paper proposes an interdisciplinary study that brings together data from faunal taphonomy, lithic typotechnology, biochronology and radiocarbon dating. Both Cave bear and Hyena used Bourdette as a den, the latter bringing remains of its prey in the cave (mostly Bovines and Horse). The presence of lithic artifacts in Bourdette seems only to be the result of post-depositional transport, so that men probably never occupied the cave itself. Biochronological data and radiocarbon dates both date the deposits around 40 ka cal. BP. Some bear bones were gnawed by hyenas, thus indicating that occupations of the cave by the two carnivores were, at least in part, broadly contemporaneous. The intensity of polishing is particularly intense on Bourdette bones, probably due to bear circulations in the cave ("charriage à sec"), to the point that procedures used commonly in bone taphonomy were severely undermined.
