During production, an error was introduced. On page 1039, it states:
• Sample AAR-21258 (elm) was measured with a 14C age of 1082±25 years.
This corresponds to a calibrated calendar age between 895–1017 BC (95% probability; dates calibrated in OxCal v4.2.3 using the IntCal13 curve; Bronk Ramsey 2009; Reimer et al. 2013).
• Sample AAR-21259 (oak) was measured with a 14C age of 1091±25 years.
This corresponds to a calibrated calendar age between 893–1012 BC (95% probability).
BC is incorrect, as this should say AD. The corrected text can be found below:
• Sample AAR-21258 (elm) was measured with a 14C age of 1082±25 years.
This corresponds to a calibrated calendar age between 895–1017 AD (95% probability; dates calibrated in OxCal v4.2.3 using the IntCal13 curve; Bronk Ramsey 2009; Reimer et al. 2013).
• Sample AAR-21259 (oak) was measured with a 14C age of 1091±25 years.
This corresponds to a calibrated calendar age between 893–1012 AD (95% probability).
