Hatula is the only site in the southern Levant where a relative sequence of the Khamian and the Sultanian could be documented (Lechevallier, Ronen 1994). However, because there is a Natufian layer beneath the Khiamian, possible mixtures of the upper Sultanian and lower Natufian layers cannot be ruled out (cf. Kuijt 1997).

Unfortunately, there are only three radiocarbon dates of the Gif-sur-Yvette (Gif) laboratory that all date different layers (for the interpretation of the Gif-dates s.Mureybet). Whereas the oldest date of the lower layer points clearly to an Epipalaelolithic context before the start of the Younger Dryas, the date of the so-called Khiamian layer, 10150-9650 BC (66%), ranges in the second half of the Younger Dryas. The date of the Sultanian layer, 9820-9320 BC (68.2%), is only slightly younger. Both dates are roughly contemporary with the late Natufian/Khiamian of the middle Euphrates.
