This paper presents a new series of AMS dates on ultrafiltered bone gelatin extracted from identified cutmarked or humanly-modified bones and teeth from the site of Abri Pataud, in the French Dordogne. The sequence of 32 new determinations provides a coherent and reliable chronology from the site's early Upper Palaeolithic levels 5-14, excavated by Hallam Movius. The results show that there were some problems with the previous series of dates, with many underestimating the real age. The new results, when calibrated and modelled using a Bayesian statistical method, allow detailed understanding of the pace of cultural changes within the Aurignacian I and II levels of the site, something not achievable before. In the future, the sequence of dates will allow wider comparison to similarly dated contexts elsewhere in Europe. High precision dating is only possible by using large suites of AMS dates from humanly-modified material within well understood archaeological sequences modelled using a Bayesian statistical method.
本文提出了一系列新的 AMS 测年数据，这些数据来自法国多尔多涅地区阿布罗塔德遗址中经过鉴定的有切割痕迹或经过人类改造的骨胶原和牙齿的超滤液。这一系列新的 32 个测定结果提供了一个连贯可靠的年代序列，涵盖了由 Hallam Movius 挖掘的遗址的早期旧石器时代晚期 5-14 层。结果表明，之前的一系列日期存在一些问题，许多日期都低估了实际年龄。使用贝叶斯统计方法对新结果进行校准和建模，可以详细了解遗址奥瑞纳文化 I 期和 II 期的文化变化速度，这在以前是无法实现的。未来，该日期序列将允许与欧洲其他类似日期的背景进行更广泛的比较。只有通过使用贝叶斯统计方法对经过人类改造的材料进行大规模 AMS 测年，并对理解透彻的考古序列进行建模，才能实现高精度的测年。
