A PREHISTORIC BREEDING POPULATION OF HARP SEALS ( PHOCA GROENLANDICA) IN THE BALTIC SEA
A bstract The pelagic and gregarious, low Arctic harp seal ( Phoca groenlandica ) is the most common seal species in most refuse faunas from coastal hunter‐gatherer sites dating from the late Atlantic to the early Subboreal period ( ca. 4000‐2000 cal B. C.) in the Baltic Sea. Our main objective was...
