The Middle Palaeolithic site of La Butte d'Arvigny, close to Melun, was dat
ed using electron spin resonance (ESR) method on burn flint. Five analysed
burnt flints give a mean age of 90 000 years, which ascribes Arvigny to the
Mousterian laminar complex of northern France. (C) 2000 Editions scientifi
