Bulletin de la Société préhistorique française - Année 1990 - Volume 87 - Numéro 8 - Pages 241-249ABSTRACT The lithic industry from this site is typical of the Late Tardenoisian III cultural faciès found in North- West Europe. This has been defined through research on tools and standard microliths found in the Mesolithic of the Paris Basin. All the lithic remains have been subjected to various methods of analysis. These confirm the important differences which exist in the Late Mesolithic in this region between the Tardenoisian, the Mauregny faciès and the Sauveter- rian « à denticulés ». These divergences concern both knapping techniques and microlith morphology. This site has thus become a reference site for the Late Tardenoisian III. 9 pages Source : Persée ; Ministère de la jeunesse, de l’éducation nationale et de la recherche, Direction de l’enseignement supérieur, Sous-direction des bibliothèques et de la documentation.
