摘要在墨西哥中部的特奥蒂瓦坎古城(约公元1-550年)进行了迄今为止最大规模的高分辨率年代学研究，分析了来自人骨胶原蛋白的加速器质谱仪放射性碳(AMS 14C)数据(n=78)。样本来自拉文蒂拉的居民区，位于这个主要城市中心的中心。在这里，使用贝叶斯统计的梯形模型是根据14C年代结合从埋葬环境中获得的陶瓷的风格分析得出的数据而建立的。基于这个模型，我们建议对特奥蒂瓦坎的陶瓷年代学进行可能的改进，至少在La Ventilla附近是这样。我们还探讨了特奥蒂瓦坎在Metepec和Coyotlatelco阶段政治崩溃后放弃和重新占领La Ventilla的情况。研究结果表明，这些陶瓷相开始的时间比目前预测的要早，而且有充分证据的La Ventilla遗弃期可能比最初估计的更突然。
ABSTRACT Accelerator mass spectrometry radiocarbon (AMS 14C) dates (n = 78) from human bone collagen were analyzed in the largest high-resolution chronology study to date at the ancient city of Teotihuacan in central Mexico (ca. AD 1–550). Samples originate from the residential neighborhood of La Ventilla, located in the heart of this major urban center. Here, a trapezoidal model using Bayesian statistics is built from 14C dates combined with data derived from the stylistic analysis of ceramics from burial contexts. Based on this model, we suggest possible refinements to Teotihuacan’s ceramic chronology, at least within the La Ventilla neighborhood. We also explore the abandonment and reoccupation of La Ventilla after the political collapse of Teotihuacan in the Metepec and Coyotlatelco phases. Findings suggest that these ceramic phases began earlier than is currently projected and that the well-documented abandonment period of La Ventilla may have occurred more abruptly than originally estimated.
