Bulletin de la Société préhistorique française - Année 1975 - Volume 72 - Numéro 4 - Pages 125-128Abstract. — In the B2il. - B4 horizon of a podzol on the continental dunes of Linkhout a small concentration of prehistoric artifacts was found. Nearly the totality of these artifacts are made from Wom- mersom quartzite. The most caracteristic feature of this industry consists in the numerous perforators. This industry is tentatively ascribed to an old Mesolithic. 4 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.
