But the most interesting discovery has to do with the sediment layers of the rock shelter, which indicate that the scrapers predate both the volcanic ash and camel teeth. Through multiple rounds of radiocarbon dating and analysis, it has been determined that these scrapers date back to 18,250 years before the present (BP).
Ongoing examinations are being conducted on the bison and camel teeth, as well as plant samples retrieved from the remnants of cooking fires.
