AlUla, The Royal Commission for AlUla (RCU) announced that a team of archaeologists has reached the first comprehensive description of human settlements in the northwest of the Kingdom of Saudi Arabia during the Neolithic period. This achievement was made through a study supervised by the authority, which found evidence indicating that the region's inhabitants in the sixth and fifth millennium BC was more stable and developed than previously thought, the Saudi Press Agency (SPA) reported. The research indicates that the inhabitants of this area were herding cattle, and practicing the jewelry industry, and the business of trade, as their location helped them to engage in their trade with the various neighboring areas such as East Jordan and areas overlooking the Red Sea. The study indicates that the stone slabs erected in two rows in the outer circumference of the circle appear to have been used as foundations for wooden columns (possibly Acacia) that were used to support the roof of the dwelling, with a sl ab in the center of the circle to support the main wooden column. The tools and animal remains found at the site indicate that the ceilings may have been made of animal skins. The study also revealed that the types of arrowheads found closely matched those used in southern and eastern Jordan, which is a clear indication of the interaction and interdependence between the inhabitants of the two regions.
