The Middle to Upper Palaeolithic Transition in the Levant and New Thermoluminescence Dates for a Late Mousterian Assemblage from Jerf-al Ajla Cave (Syria)

Thermoluminescence dating of eight heated flint artefacts from the Late Mousterian (Moustérien tardif) layer С at Jerf al- Ajla, cave in the Syrian steppe desert near Palmyra gave an average age of 33.3 ±2.3 ka. The assemblage shows strong similarities to the Middle to Upper Palaeolithic stratigraphically intermediate layers from the nearby site of Umm el Tlel, which are dated by the same method on the same kind of material to a statistically identical age. This dating result extends the age range of the Middle Palaeolithic in the Levant and indicates a considerable overlap in time with not only the Upper Palaeolithic, but with the transitional industries as well. The Levantine technocomplexes assigned, to the times before, during and after the Middle to Upper Palaeolithic shift/transition are briefly discussed here, with a focus on the chronometric data available. The presented new dating results emphasize the complexity in the development lithic and the difficulties a single model to times of change.
