Only a limited number of radiometric dates for the Final Palaeolithic and the first half of the Mesolithic are available from the south-eastern Baltic. This paper presents eight new Late Pleistocene/Early Holocene AMS dates obtained by dating osseous artefacts housed at the Kaliningrad Regional Museum of History and Art: One piece of worked reindeer (Rangifer tarandus) antler, three axes of the (problematically named) ‘Lyngby' type, one bone point, one uniserial harpoon, one so-called “bâton percé” antler tool, and one slotted bone point were sampled. Two of the specimens were further subjected to subsequent protein-based species analysis for taxonomic identification. All dating attempts were successful and have provided five Late Pleistocene and three Early Holocene dates, including the hitherto earliest date for human occupation in the Eastern Baltic, a surprisingly early date for a bone point, but also dates that strongly contradict expected ages based on the traditional typological assessment. In sum, these new dates increase the existing radiometrically dated artefact database significantly and stimulate new ways of viewing the Final Palaeolithic and Early Mesolithic chronology in the region.
