C14 Radiocarbon Dating - Sample - AA-48604

Human neonate bone from layer 465, a floor layer within House 401 (the central roundhouse) in Area A (the main trench excavated in 1996-2001). This layer of peat dust and sand contains debris deriving from activities that took place on its surface. South Uist Human Remains Project Sample 26 PROBLEM: As of 2009, the calibration is uncertain because the marine effect varies (Ascough PhD). There is a108429ther possible problem; the 13C/12C ratio may vary in neonates.
