In conformance with the request of the editors, ages in this date list have been calculated with the Libby half life value, 5568 ± 30 yr. We should like to mention, however, that the “effective” and, possibly, the true value may differ from this by several hundred years (see discussion by Kohler and Ralph, 1961). The measurements of samples of known age indicate that the “effective” half life value is close to 5800 yr, except for specific recent periods.
