Radiocarbon dating minute amounts of bone (3–60 mg) with ECHoMICADAS

Abstract Because hard tissues can be radiocarbon dated, they are key to establishing the archaeological chronologies, palaeoenvironmental reconstructions and historical-biogeographical processes of the last 50,000 years. The advent of accelerator mass spectrometers (AMS) has revolutionized the field...
