• The pluridisciplinary research carried at Le Cuzoul-de-Vers (Lot, France) over 15 years has been published in late 2012. This publication makes available the data acquired at the end of the 2000s on one of the most important Western European sites for the study of the Last Glacial Maximum (LGM) societies. From this point new interdisciplinary research projects have been built leading to several complements and/or extents. Among them, a reassessment of the radiometric framework due to new AMS 14C dates obtained with the collaboration of Lyon, Saclay and Oxford laboratories is presented here. Eleven new radiocarbon measurements resulting of the direct dating of Badegoulian antler waste products and Solutrean faunal remains whose stratigraphic position has been controlled allow us to specify and/or modify the results previously published. These data tend to confirm (1) the small chronological amplitude of the entire sequence, (2) the old age of the Badegoulian occupations, (3) the very short chronology of the Solutrean levels and (4) the transience of some occupation episodes whose radiometric individualization remains illusory. Led in parallel to an archeostratigraphic analysis in progress (inter-layers refitting), this preliminary work shows the necessity to precisely redefine the assemblages studied. As a collective work, this approach is part a wider program (Collective Research Program �SaM�) aiming at a better chronological seriation of the techno- and socio-economic changes documented in the early part of the LGM north of the Pyrenees.
