C14 Radiocarbon Dating - Sample - UB-3672

Marine shell from II 13 waterlogged midden deposit on periphery of settlement. See also UB-3668 (4129 +/- 29) from animal bone in the same context. 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
