Résumé
"The Druze Marsh is a spring-fed wetland in northeast Jordan that, due to years of over-pumping the aquifer, dried out completely in the 1980s. This study combines detailed stratigraphic and sedimentological analysis of seven test pits and one controlled excavation in the exposed marsh bed, with artifact analysis and radiometric dating, to reconstruct the changing landscape since the Middle Pleistocene and relate hominin use of the area to environmental change. The results show that there are extensive hominin occupations in the Druze Marsh from the Late Lower Paleolithic through the Epipaleolithic that correspond to relatively dry environments when the wetland was reduced in size, suggesting the Druze Marsh acted as a desert refugium for hominins during adverse climatic conditions, with important implications for regional population continuity, turnover, and/or extinctions. Separating these occupations are extended periods when the wetland increased in size and depth, becoming a shallow lake that drowned land previously available for hominin occupation and forcing these populations into the surrounding river channels that flow into the central basin. Positioned at the north end of a string of paleolakes that connects the Levantine Corridor to the west and central Arabian Peninsula to the southeast, river networks around the Druze Marsh may have provided an additional inland route for hominins dispersing between Africa, Eurasia, and the Arabian Peninsula during wetter climates. Establishing the full significance of the Druze Marsh and other desert paleolakes for hominin survivorship and dispersal during the Middle and Late Pleistocene requires additional joint paleoenvironmental and archaeological research."--
