Аннотация:The excavations of the Eastern Jafr Project investigated one of the nine prehistoric wells that supply watering complexes at Qulban Beni Murra. These are related to pastoralist populations present in the area during the latter part of the Chalcolithic, and which marked the landscape characteristic of megalithic burials. This well-based pastoralism was characterized by an approach to water management that was probably transmitted to the later, well-based gardens of proto- and early oases. The archaeological results of the well structures serve as the basis for further discussion of the social and technical adaptations that appear to have paved the way for oasis development on the Arabian Peninsula.
