Abstract : Though the Bell Beaker ceramics, remarkably decorated, is often studied and published, the lithic assemblages linked to the same culture have always been considered as poor, non-significant and irrelevant. An archeological approach of this kind of artefacts is meant to reintroduce it inside the current problematics of Bell Beaker through Europe.
Based upon the southeastern France example where more than 300 sites were discovered, this PhD study emphasizes the chronocultural pertinence of the Bell Beaker lithics by the characterization through the technological analysis of 9 reference lithic sets. The industry is analysed and interpreted in relation with the whole archeological data (ceramics, metal, bones, ...). This work permitted to propose a new hypothesis concerning the evolution of Bell Beaker culture in the southeastern France and its spread all over Europe at the end of the third millenium B.C.
