TL;DR: Al Wusta shows that early H. sapiens dispersals out of Africa were not limited to winter rainfall-fed Levantine Mediterranean woodlands immediately adjacent to Africa, but extended deep into the semi-arid grasslands of Arabia, facilitated by periods of enhanced monsoonal rainfall.

TL;DR: The discovery of three stratified and buried archaeological sites in the Nefud Desert is described, which includes the oldest dated occupation for the region and stone tool assemblages are identified as a Middle Palaeolithic industry that includes Levallois manufacturing methods and the production of tools on flakes.

TL;DR: In this paper, a combined method for remotely mapping the location of palaeodrainage and palaeolakes in currently arid regions that were formerly subject to more humid conditions is presented.

TL;DR: In this paper, the authors present a new record from the site of Al-Rabyah, in the Jubbah basin (southern Nefud desert, Saudi Arabia), where a sequence of fossiliferous lacustrine and palustrine deposits containing an archaeological assemblage is preserved.

TL;DR: An important contribution to the record is described and stratigraphically-constrained fossils of mammals, birds and reptiles from recent excavations at Ti’s al Ghadah in the southwestern Nefud Desert are described, infer that the assemblage reflects mortality in populations of herbivorous animals and their predators and scavengers that were attracted to freshwater and plant resources in the inter-dune basin.
