A New Bayesian Chronology for Mesolithic Occupation at Mount Sandel, Northern Ireland

Mount Sandel has long been an iconic site for the Irish Mesolithic, having produced evidence for a sequence of occupation huts and pits and the earliest radiocarbon dates for the Mesolithic on the island. This paper presents details of a recent programme of redating whereby the application of Bayesian modelling has confirmed the early date for the site but also helped to refine its internal chronology. The major phase of hut building at Mount Sandel took place within a much shorter period of time than had previously been thought, perhaps only a generation or two. The dating of pits of differing sizes suggests that many of them were created during other slightly later visits to the area. The implications of the dating programme for the place of Mount Sandel in the Irish Mesolithic, and for the chronology of the period and its relations with that on the British mainland, are discussed.
