ABSTRACT. Twenty-three samples of charred food remains, charcoal, burned animals, and human bones from 14 Lithuanian prehistoric sites were dated by radiocarbon as part of a dating project oriented towards renewing the prehistoric ceramics chronology. The new dates modified the dating of ceramic styles by hundreds to a thousand years. Three Textile Ware sherds were dated to 4230-2920 cal BC-the oldest known dates of Textile Ware pottery in the East Baltic. The organic-tempered pointed-bottomed Narva and Combed-like Wares were dated to 3970-3370 cal BC, while Bay Coast Ware (Haffküstenkultur, Rzucewo), including vessels decorated with cord impressions, were dated to 3940-3540 cal BC, i.e. to a period well preceding the Corded Ware/Battle Axe horizon in Europe. Three dates of Globular Amphorae Ware placed the phenomenon directly beyond the Bay Coast chronology, i.e. in 3450-2920 cal BC. Chamotte-tempered Corded Ware from SE Lithuania was dated to 2840-2570 cal BC. The first absolute dating of coarse ware of the Žalioji type pointed to a period of 760-515 cal BC instead of the previously assumed 2nd millennium cal BC. Cremated human bones from urns found at Paveisininkai, Kernavě, and Naudvaris cemeteries were dated to 790-380 cal BC. Accelerator mass spectrometry (AMS) dates obtained from charred food remains should be treated with a certain caution due to a possible freshwater reservoir effect that has not yet been examined in Lithuania.
