Abstract

- 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.
