Radiocarbon Dates From the Oxford Ams System: Archaeometry Datelist 30

the series is of great importance in increasing the number of directly dated Mesolithic human remains from Britain, while the combined dating and stable isotope results provide additional strong support for the view that Mesolithic coastal groups relied to a far greater extent on marine foods than seen in any subsequent period (Schulting 1998; see also Richards and Hedges 1999).The demonstration of the significant use of marine foods from an early date (OxA-7686) is another important result.The uniqueness of Mesolithic adaptations within the British context is further emphasized by the presence of three earlier Neolithic individuals from Nanna's Cave (OxA-7739, -7740) and Ogof-yr-Benlog (OxA-7743) with stable isotope values indicating typically terrestrial diets, despite being even closer to the sea than during the Mesolithic, when the shoreline would have been up to a few kilometres distant.Finally, although it is known that caves were being used for burial in Wales (Branigan and Dearne 1992), the Romano-British dates obtained here (OxA-7685, -7689) may be the first directly dated examples (although intentionality is not certain for any of the human remains from the Caldey sites).
