Radiocarbon dates published previously, and the new dataset was obtained in the context of this work. All dates were calibrated in OxCal [16] using the IntCal20 curve [17].

Radiocarbon dates published previously, and the new dataset was obtained in the context of this work. All dates were calibrated in OxCal [16] using the IntCal20 curve [17].此前已发表的放射性碳定年数据，以及本研究中获取的全新数据集，全部定年结果均通过OxCal软件[16]，基于IntCal20校正曲线[17]完成了定年校正。
