"This update on radiocarbon calibration
results from the 19th International
Radiocarbon Conference at Oxford in April
2006, and is essential reading for all
archaeologists. The way radiocarbon dates
and absolute dates relate to each other
differs in three periods: back to 12400 cal
BP, radiocarbon dates can be calibrated
with tree rings, and the calibration curve
in this form should soon extend back to
18000 cal BP. Between 12400 and 26000 cal
BP, the calibration curves are based on
marine records, and thus are only a best
estimate of atmospheric concentrations.
Beyond 26000 cal BP, dates have to be based
on comparison (rather than calibration)
with a variety of records. Radical
variations are thus possible in this
period, a highly significant caveat for the
dating of middle and lower Paleolithic art,
artefacts and animal and human remains."
