New research on the settlement of the Magdalenian culture in the Polish lands has made it possible to discover new sites. These new sites come mainly from two regions: Sandomierska Upland, at the confluence of the two rivers Vistula and San, and in south-eastern Poland. In the latter region, the sites are associated with the valley of the San and its tributary, the Wisłok. The two regions are linked by a network of raw material links and also by their distribution along the San and at its confluence with the Vistula. The new discoveries in eastern Poland raise questions about both the boundaries of the Magdalenian and the relationship between Magdalenian and Epigravettian settlements.
