Extensive excavations of Stone Age sites in Western Pomerania have been conducted since 1981. Three of them, the Rotnowo site 18, Tanowo site 3 and Bolków site 1, were selected as Tanged Point Younger Dryas key sites. These open sandy sites revealed well-preserved flint concentrations and a dwelling structure (Tanowo). Their flint inventories, with elements of Ahrensburgian culture, are made up of local flints. Younger Dryas chronology is supported by geology and C14 from Rotnowo: 10820±80 BP [Poz-8309] (cal. 11180–10830 BC). The results of the investigations were compared with settlements from other regions of Poland and with sites from Lithuania and Latvia.
