 This culture is known for the high percentage of burins and some of these were similar to the distinctive nosed profile of the Aurignacian burins.Radiocarbon dates suggest that this was one of the earliest Upper Paleolithic complexes, beginning perhaps as early as 36,000 BC.Evidence found in the Yafteh cave assemblages, revealed that the early phase of this culture was not as sophisticated as the evolved middle phase, and it produced blades and bladelets using soft hammer from single platform prismatic cores with plain platforms.
