When 14C Dates Fall Beyond the Limits of Uncertainty: An Assessment of Anomalies in Western Mediterranean Bronze Age 14C Series

Vicente Lull, Rafael Micó, Cristina Rihuete-Herrada, Roberto Risch


The aim of this article is to bring to light a serious problem affecting radiocarbon dates produced at least from 2009 onwards by the AMS Leibniz laboratory at the Christian-Albrechts-Universität (Kiel, Germany). Archaeological observations and cross-checkings between several laboratories confirm that in a significant number of dates, clear deviations of the results from chronological schemes based on stratigraphical sequences and hundreds of measurements have occurred, which usually implies an aging of the 14C values.
