The environmental context of Paleolithic settlement at Jebel Faya, Emirate Sharjah, UAE

摘要

Key to the understanding of Pleistocene human dispersals and settlement dynamics is knowledge about the distribution of human habitats in space and time. To add information about the characteristics of inhabited environments along the South Arabian dispersal route, this paper presents paleo-environmental data from deposits excavated at Jebel Faya (FAY-NE1) in the Emirate of Sharjah, UAE. The sedimentary sequence at FAY-NE1 spans a period of about 125,000 years, including the last interglacial and the Hol-ocene. Particle size and phytolith content of samples from two sediment columns were analyzed, including both archaeology bearing layers and archaeologically sterile layers. The results demonstrate that human occupation of the site is related to pluvial periods. Assemblage C, dated to about 127-123 ka, was deposited during a wet phase with an environment characterized by an increased proportion of C_3 grasses. Grassland with sedges but lacking tree cover characterize ecological conditions during the youngest of the Paleolithic occupation periods, Assemblage A, dated to about 45—40 ka. Environmental conditions during periods lacking archaeological remains are characterized by the absence of vegetation cover during phases of desiccation. There is no evidence for human presence at the site between 38 and 11 ka.
