| Summary: | The site of Le Flageolet (Bézenac, Dordogne) contains two rock shelters excavated between 1966 and 1993. Le Flageolet I, the subject of this paper, opens to the west. On the bedrock, a first lithostratigraphic unit yielded three Aurignacian archaeostrata in a mass of very large blocks that collapsed before or during the earliest human occupations. A second overlying lithostratum contained at least six Gravettian archaeostrata. Due to the complexity of this archaeostratigraphy, we conceived and applied a method of excavation based on the three-dimensional recording of all artefacts with a maximum dimension over 1.5 cm, the use of artefact drawings at a scale of 1/5, and feature distributions, and the concomitant production of narrow vertical artefact projections along various frontal and sagittal axes. This method allowed for tight control over the definition and integrity of artefact levels. Analyses of the resulting assemblages show that the traditional regional cultural “markers” do not have the unambiguous chronological significance attributed to them in the past based on interpretations from excavations at La Ferrassie, Pataud, Caminade, and Roc-de-Combe. The large ungulate mammal biostratigraphy enabled us to chronologically position all the Aurignacian and Gravettian faunal assemblages from Le Flageolet I in relation to those from other Aquitaine sites; the faunal remains allow for the identification of particular environmental conditions that may be considered as “key events,” marking certain specific periods during the development of the Aurignacian-Gravettian sequence. Based on radiocarbon ages, several major Aquitaine sites, including Le Flageolet I, have been situated on the NGRIP climatic curve, thereby providing a chronological context independent of stone tool technology and typology. Based on all of this, a chronological-cultural model can be proposed that considers functional variation as an important influence on Aurignacian and Gravettian assemblage composition at Le Flageolet I and elsewhere. ...
