This article presents a new archaeological material to discuss methodological issues encountered by scientists working both on minimally-modified bones from Mousterian assemblages, to those dealing with the identifica- tion of “retouchers” having a flaked bone aspect. The technological approach integrates complementary analyti- cal study-frames in order to assess archaeological information. On the one hand, analogies with similar experi- mentally produced patterns reduce the functional identification of the archaeological specimen. They do not deal with a single artefact-type in the category of “retouchers”, which thus remains generic. On the other hand, the recording of the patterns in their chronological order, combined together with that of modifications relative to the diagenesis of the bone as an artefact, suggests the “retoucher” was reduced in a relatively fresh state by a carnivorous predator also. The evidence of this co-occurrence, if characterizing the successive anthropic-origi- nated bone beds ultimately degraded by predators in situ, would suggest a relatively short period of human oc- cupation generated by the use of the site in a singular cyclical conception “prey-hunter-predator” at regional scale
