  1. Calibrated dates according to OxCal38 are presented based on the NHZ2 calibration curve32. All calibrated dates are within the 1σ range, probabilities are presented as percentages. For dates beyond the current calibration curve (after 2009), 2σ range is shown and indicated in bold. From the possible date ranges suggested by radiocarbon, we present our subjective likely option in the last column, based on the radiocarbon probability, as well as the location of the sample (near the bark are expected to be ~2013, for which the calibration curve is not yet updated and instead provides an output of ~1956).
