On the polysemic nature of traces and co-occurring patterns in anthropized material — contribution of a “Retoucher” with a flaked bone aspect from Roc-en-Pail (France)

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 identification of “retouchers” having a flaked bone aspect. The technological approach integrates complementary analytical study-frames in order to assess archaeological information. On the one hand, analogies with similar experimentally 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-originated bone beds ultimately degraded by predators in situ, would suggest a relatively short period of human occupation generated by the use of the site in a singular cyclical conception “prey-hunter-predator” at regional scale.
