Bifacial Neolithic tools and weapons (ABT) (Phase II) have been found in profusion over the length and breadth of Arabia. Many have been found along the Rub al Khali fossil lakes. They represent a vast array of hunters focussing on such varied game as equids, bovids, oryx, antelope, wild sheep and goats, and ostrich. They mined their flint from rich sources in many Arabian localities.
