C14 Radiocarbon Dating - Sample - GU-1972
GU-1972
Shell from sample 81/F 2 of dumped material in a midden. 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. CHECK NEEDED to see if d13C value really positive or '-' simply not entered by me.
