The radiocarbon dates of Ain el-Kerkh are consistent with the stratigraphy, except for one date (OxA 2555) from material that was probably dislocated from a lower layer.[1]The sum of the dates indicates an occupation of the settlement between 8550 BC and 8310 BC.[2]
[1]It is striking that the conventional date of Lyon is the most recent one, although its stratigraphic position was in a middle layer. As no other sample of the same layer has been dated by another laboratory, it is not possible to verify if the deviation of the date is due to the laboratory.
[2]Σ: 8550 BC (11.9%) 8500 BC; 8490 BC (56.3%) 8310 BC.
