Abstract : Denticulate Mousterian, considered as one of the traditional facies of Mousterian, is submitted to a critical re-examination. The preliminary development of a methodology suitable for the study of the notched pieces allowed to differentiate the pseudo-tools from the true notched pieces and thus to determine the techno-economic characteristics of the latter.
The study of five lithic industries (Les Fieux, Saint-Césaire Egpf, IVb1 Hyène, Bison G and H) as well as a first analysis of the material of Combe-Grenal c. 11 and the retouched pieces of Mauran and La Borde demonstrate a certain constancy in the production schemes of the series attributed to Denticulate Mousterian.
This study, coupled to a documentary review synthesizing the available bibliographical data, by the crossing of typological, technological and economic characters, allows to subdivide the Denticulate Mousterian in three groups. Each one of these groups shows many particular characteristics, in which the light quantitative variations can be linked to an adaptation to specific needs related to the type of occupation.
