The Arabian Peninsula, due to its geographical location, offers a unique opportunity to study dramatic changes in the palaeoenvironment that occurred over the last 150.000 years, switching from uninhabitable deserts to humid palaeolandscapes with palaeolakes, wetlands and active fluvial systems. Traces of these extreme changes in climatic conditions are recorded in ancient paleolake, wetland, alluvial and fluvial deposits. The alternation of dry and wet phases also influenced the presence of wildlife, and pre-conditioned the chances of succes for human settlements and migration. This session invites multi-proxy, multi-disciplinary contributions on the Geoarchaeology of the Arabian Peninsula, with an emphasis on the interaction of biota (plants, wildlife, humans) and changing paleoenvironment during times of alternating dry and wet phases.
