Gesher is one of the rare sites consisting of a single occupational phase. It has been attributed either to the Khiamian or to the Sultanian (Garfinkel, Nadel 1989:149; Nadel 1990:97). In fact, the radiocarbon dates scatter between 9670 and 9190 BC. However, two of the dates correlate well (Pta 4553: 9770-9370 BC; Pta 4595: 9450-9250 BC) with the data of Mureybet, Niveau IA/B and II, (thus with the late Natufian and early Khiamian) and with Phase 2 of Jerf el Ahmar.

Due to their larger deviation of +/- 140 years, the two remaining dates cover a time range down to 9200 BC, but the sum of the dates makes an earlier occupation more probable.
