Can calcined bones be used to date Final Palaeolithic and Mesolithic open-air sites? A case-study from the Scheldt basin (NW Belgium)

Abstract This paper presents the results of an inter-comparative study in view of assessing the reliability of radiocarbon dates obtained on calcined bones from open-air Palaeolithic and Mesolithic sites. The results demonstrate that the success rate is largely dependent on site-taphonomy, in particular the speed of covering of the site. Sites quickly covered by aeolian, alluvial or marine sediments yield on average good dating results. At worst they can be affected by an wood-age offset, generally
