Rapid environmental changes in southern Europe during the last glacial period. There is a difference between the two results but given the uncertainties associated with the sample, the magnitude of the difference is not too unreasonable. Integrity and characteristics of the bones of the Danish King St Knud (II) the Holy (†AD 1086).

Their calibration is slightly problematic, because the d13C-values are in the range of marine samples. the above diagram is prepared using the Terrestrial calibration curve (N. samples Hd-20755, Hd-20756 and Hd-20758 come out 400-800 years younger if the Marine calibration curve is used).
If that were the case they would have to be calibrated against the marine calibration curve, which would decrease the age by at least 400 and at most 800 years. The samples from MR6.1 (OZE-165 and OZE-166) and MR6.3 (NZA-8042) were all dated using the AMS method.
Sample GU-9186 comprised a scattering of small charcoal fragments within a carbonate sand matrix.
The bulk of the woody material was dated, and one of the largest fragments, AA-40741 (GU-9186A), was separately dated by AMS.
