C14 Radiocarbon Dating - Sample - TO-7194

Human bone from a disturbed burial 1963A with burial goods; calibration after Barrett et al 2000, 6-8. PROBLEM: As of 2009, the calibration is uncertain because the marine effect varies (Ascough PhD) but the fairly normal d13C value means any variation would be very small.
