Although it is beyond the scope of this analysis to discuss the complex stratigraphy of Iraq ed Dubb (Kuijt et al. 1991; Kuijt 2002-2004), it should be noticed that the radiocarbon dates show a hiatus during the Younger Dryas and that they hint at two or even three different occupational phases.
The oldest date GX 17077 ranges between 11200 BC and 10980 BC, and there are two dates around 10880-10730 BC. Whereas the early date is of charcoal and can probably be explained as an old-wood effect, the two younger dates are charred pistachios and clearly document a short occupational phase.
The remaining three samples are all later than the Younger Dryas, ranging between 9660 BC and 9290 BC with a highest probability at 9470 BC to 9290 BC. Thus, the radiocarbon dates clearly indicate a hiatus during the Younger Dryas.
