C14 Radiocarbon Dating - Sample - SUERC-3384

Limpet shells from test pit in a cave 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.
