In this article a survey is given of paleolithic sites and flint finds in the Province of Overijssel. Only one middle paleolithic artifact is known, a Moustérien point at Deldenerbroek. Of the young Paleolithic at least two sites of the Hamburg culture came to our knowledge, six sites of the Federmesser culture, one site of the younger Dryas (Preboreal) period (more or less like the Ahrensburg culture, but without tanged points) and six sites with late paleolithic finds, not precisely determinable by lack of (typical) flints. The finds of the Hamburg culture at Luttenberg proved to be in younger coversand (I), and thus are dated post Böiling. In this complex attention has been paid to secondary retouch and the influence of fractures on blades.
