Upper Paleolithic scrapers from Chatelperron. Chatelperronian was the earliest industry of the Upper Palaeolithic in central and south western France, extending also into Northern Spain. It derives its name from the site of la Grotte des Fees, in Chatelperron, Allier, France. It arose from the earlier Mousterian industry. It made use of the Levallois technique of lithic reduction (stone-knapping) and lasted from between c. 45,000 and c. 40,000 BC. The industry produced denticulate, or toothed, stone tools and also a distinctive flint knife with a single cutting edge and a blunt, curved back.
