Périgordian is a term for several distinct but related Upper Palaeolithic cultures which are thought by some archaeologists to represent a contiguous tradition. Thought to have existed between c.35,000 BP and c.20,000 BP the Perigordian was theorized by prehistorians (namely ). The earliest culture in the tradition is the Châtelperronian which is thought to have produced denticulate tools and flint knives. It is argued that this was superseded by the Gravettian with its points and Noailles burins. The tradition culminated in the proto-Magdalenian.
