C14 Radiocarbon Dating - Sample - SUERC-753

A limpet shell (2) from a shell midden WV3 consisting predominantly of oyster shell, with some limpet and mussel, occasional sea bird and marine mammal bones. PROBLEM: As of 2009, the calibration is uncertain because the marine effect varies (Ascough PhD) and it is not safe simply to correct the age by 405 C14 years
