These are some Upper Paleolithic surface findings from the Bergerac vicinity-all made of Bergerac chert. (1: Double Scraper, 2: Projectile Point , 3: Scraper-Burin, 4: Burin with basal notch; 5: Endscraper [2: Limeul / Magdalenian; other items: Le Porget, Corbiac /from Aurignacian to Magdalenian]).
An large number of lithic raw material surveys has been conducted in South- Western France over the last 40 years. Bergerac chert from spatially localized deposits was exploited extensively by paleolithic groups in the region since the Acheulian. Highly coloured and banded Bergerac flint is of Maastrichtian origin and usually found in the form of larger nodules, especially suited for the production of handaxes and longer blades. During the Middle Paleolithic, Bergerac chert is found as far away as 100 km from the source (Les Fieux, Le Plane, Le Mas-Viel). During the Upper Paleolithic Bergerac chert was distributed as far as 330 km to the south-east (Regismont le Haut), 260 km to the south-west (Isturitz) and 255 km to the north (Les Roches). At the Abri Pataud in Les Eyzies mainly local lithic raw materials were used during the Aurignacian, while the importance of of Bergerac chert increased in the Gravettian assemblages of this site. This may reflect the gradual evolution of new mobility patterns and / or the emergence of new networks during the upper paleolithic in the Vezere valley.
