This ambiguity may be reduced by the inclusion of additional isotopic proxies, that is, by including less commonly employed isotopic systems (e.g.
sulphur isotopes) and/or performing isotopic measurements on a larger variety of consumer tissues and/or molecular compounds (e.g. In this respect, Jaouen and Pons discussed the potential of progressively employing non-traditional isotopic proxies (e.g. employed a multi-isotopic approach in the study of human diet or mobility. investigated the mobility of individuals from burial sites near Madrid (Spain) dating to the Late Neolithic, Chalcolithic, and Bronze Age using strontium and oxygen isotope ratios measured in teeth and bone. In addition, carbon isotope ratios suggest a dietary shift at c.
Human diet reconstruction was done using a Bayesian mixing model and relied on stable isotope measurements on humans and a large amount of locally available archaeological faunal and botanical remains.
The outcome of the study observed inter-individual differences in dietary intakes (e.g.
diet-to-tissue isotopic offsets, dietary routeing, etc) and offer a probabilistic interpretation of dietary intakes. compared the dietary diversity of two populations, Solcor and Tchecar, in northern Chile dating to the Middle Period.
Bayesian modelling of isotopic data showed that the Tchecar individuals had less varied diets than those from Solcor.
Thus, an attempt at offering a complete overview of the applications and methodologies involved in isotopic analyses applied to archaeological research would represent an undertaking well beyond the limited scope of this special issue.
This study concerned pottery use which is often investigated through carbon stable isotope analysis of fatty acids recovered from the clay matrix of archaeological ceramic vessels. showed that special care must be taken when employing modern fat references for archaeological studies, namely when modern animals are not fed only on purely natural pastures.
Essential to isotopic studies of diet and mobility is the understanding of how isotopic signals are transferred from the environment (e.g. This is often determined through animal and human feeding experiments. discuss the impact, for different parameters, that has to be considered when interpreting oxygen stable isotope ratios measured in human teeth and bones.
The authors concluded that Middle Period individuals had a differentiated access to food resources challenging the hypothesis of uniform richness during the Middle Period.
Another aspect of Bayesian modelling is the possibility of incorporating prior information from other sources of archaeological data. that investigated the chronology of Subneolithic-Neolithic sites in Lithuania from human bone radiocarbon dates.
Instead, this issue is aimed at highlighting a selection of special themes that represent a mix of well-established and recent topics within isotopic studies applied to archaeological research.
