The subfossil seals of Finland and their relation to the history of the Baltic Sea

The occurrence of seals in the Finnish prehistoric fauna and in the Baltic since the end of the last glaciation is discussed on the basis of subfossil remains in refuses at cultural sites, and stray finds. The species represented are the harp ( Phoca groenlandica Müller), the ringed seal ( Phoca hispida Schreb.), and the grey seal ( Halicoerus grypus (Fabr.)), of which the latter two are native in the recent fauna, whereas the former has since become extinct in the Baltic. The earliest seals, which probably immigrated to the Yoldia Sea, were ringed seals, whereas the subfossil harp seals are solely found in sediments of the Litorina Sea stage.
