Marine reservoir effects (MRE) have the potential to increase the dating uncertainty of humans incorporating marine resources into their diets. Here we attempt a novel dental wiggle-match model to reduce dating uncertainty of seven individuals from the Resmo megalithic tomb (Öland, Sweden) and to test whether this model can be used to calculate MRE from a single tooth. Previous stable isotope ratio studies of these individuals demonstrated that their diets changed, between more or less marine protein, during the early years of their lives. Several incremental samples of dentine from each individual were subjected to radiocarbon dating and stable isotope ratio analysis. An OxCal model was designed that makes use of the known formation sequence of human teeth to reduce overall dating uncertainty. The new dental wiggle-match model is able to reduce overall dating uncertainty in all of the sampled individuals compared to more conventional ¹⁴C calibration methods. A utility of the dental wiggle model to estimate marine reservoir effects without associated faunal material is also demonstrated, with promising results.

海洋水库效应 (MRE) 有可能增加人类将海洋资源纳入其饮食的年代不确定性。在这里，我们尝试了一种新的牙齿摆动匹配模型，以减少来自 Resmo 巨石墓（瑞典厄兰岛）的七个个体的年代不确定性，并测试该模型是否可用于计算单个牙齿的 MRE。先前对这些个体的稳定同位素比率研究表明，在他们生命的早期，他们的饮食在或多或少的海洋蛋白质之间发生了变化。每个人的几个牙本质增量样本进行了放射性碳测年和稳定同位素比分析。设计了一个 OxCal 模型，该模型利用人类牙齿的已知形成序列来降低整体约会的不确定性。¹⁴ C 校准方法。还证明了牙齿摆动模型在没有相关动物群材料的情况下估计海洋储层效应的效用，并取得了有希望的结果。
