Abstract
Faunal remains from the Beauvais open site ‘La Justice’ (Oise) are the subject of an U-Th dating (disequilibrium of the uranium chain) and an ESR dating (electronic spin resonance). This study was performed in order to identify the chronological situation of the Middle Paleolithic levels of this site located in the north of France, supposedly aged stage 4 after stratigraphic correlations. U-Th ages of bones and dentine are between 20 and 200 ka and are scattered; however, the combined ESR/U-Th ages of rhinoceros dental enamels are homogeneous and indicate that the archaeological levels were deposited between 60 to 40 ka. This period corresponds to the end of the oxygen isotopic stage 4 to the beginning of stage 3.
