Study finds hafted points in Najran 125,000 years ago.

At Uruq al-Jilbah, on the shore of an ancient lake, the study’s evidence points to more than a passing stop: the distribution of tools, their spatial association with fossils, and the preservation of tiny organic traces support the researchers’ view that people returned to the site over time. Among the finds are stone points, some fixed to handles with adhesives and plant-derived bindings. Analyses found traces of plant fibers, wood, resin, fats and collagen on some tools; some points also showed impact fractures. Chemical indicators associated with Acokanthera, the study says, support the possibility that some tools were used in composite hunting techniques. The evidence can’t establish how the materials were prepared, their concentration or their effectiveness. The lakeshore also brought together freshwater, plants, animals and raw materials.
