The analysis provides a novel understanding of the technological details of the bone and antler manufacture in the 9 th and 10 th millennia before present as a proxy to emphasize contemporary Late-Glacial-originated versus Early Mesolithic bone technologies in Denmark. This paper contributes to the knowledge of newly dated bone weapons from Sjaelland, Lolland and Bornholm's islands in the Late Paleolithic (Late Glacial, Federmesser, Ahrensburg cultures) and the Danish Early Mesolithic (Maglemose culture).
