This article, an extract from a report, is an inventory of the Upper Palaeolithic and Mesolithic sites studied by preventive archaeology along the projected linear development works in Picardy. The focus will be firstly on the various contexts and methodologies which enabled their discovery. Secondly, because of the small number of sites, a detailed proposition for an ideal approach in the future will be put forward. A practically exhaustive bibliography has been drawn up, for the use of readers interested in the more precisely scientific aspects with which this article is not mainly concerned.
