Since its development in 1949, radiocarbon dating has increasingly been used in prehistoric research in order to get a better grip on the chronology of sites, cultures and environmental changes. Refinement of the dating, sampling and calibration methods has continuously created new and challenging perspectives for absolute dating.In these proceedings the focus lies on the contribution of carbon-14 dates in current Mesolithic research in North-West Europe. Altogether 40 papers dealing with radiocarbon dates from 15 different countries are presented. Major themes are the typo-technological evolution of lithic and bone industries, changes in settlement patterns, burial practices, demography and subsistence, human impact on the Mesolithic environment and the neolithisation process. Some papers also deal with more methodological aspects of carbon-14 dating (e.g. calculation of various reservoir effects, the use of cumulative calibrated probability distributions), and related techniques (e.g. stable isotope analysis for palaeodiet reconstruction).
