Perigordian
Périgordian is a term for several distinct but related Upper Upper Palaeolithic cultures which are thought by some archaeologists to represent a contiguous tradition. It existed between c.35,000 BP and c.20,000 BP.
The earliest culture in the tradition is known as the Châtelperronian which produced denticulate tools and distinctive flint knives. It is argued that this was superseded by the Gravettian with its Font Robert points and Noailles burins. The tradition culminated in the proto-Magdalenian.
Critics have pointed out that no continuous sequence of Périgordian occupation has yet been found and that the tradition requires it to have co-existed separately from the Aurignacian industry rather than being differing industries that existed before and afterwards.
