The radiocarbon dates of M’lefaat are interesting because all the dates of Gliwice (Gd) except one, Gd 6356, are much older than the Oxford AMS dates. Although most of these old dates have been discarded because of their large deviations, they should be kept in mind for the interpretation of the radiocarbon dates of other Gd-dated sites (e.g. Qermez Dere, Nemrik 9).

Despite this problem, the site is dated quite precisely by several lentil seeds. As the samples do not come from the same context, but from the fill of Houses 3 and 8, their calibration ranges cannot be combined. If all the lentils documented one occupation phase, it would date between 9270 BC and 9240 BC; but because of the short overlap of the dates, they could also indicate two separate occupational phases of the Houses 3 and 8. Whereas the early dates concentrate between 9660 BC and 9220 BC, the third lentil date and Gd-6356 (discarded by Kozlowski) point to a slightly later range between 9250 BC and 8840 BC.
