Few open-air sites of this age have the same extent, complexity and diversity of deposits, as was found at the site of Solvieux in South-west France. The complexities of the site and the intensity of the archaeological investigation called for new and novel methodologies to be devised which are discussed in detail. The history of the project, methodologies, results and analysis of finds are complemented by a large number of drawings, outlines of typologies and essays on Upper Palaeolithic traditions and the contribution of the Solvieux results in this regard.
