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.

Also, studies that identify the importance of other effects (e.g. Each human tissue has specific formation times and isotopic offsets towards oxygen pools.

Furthermore, heating, through cooking, modifies the isotopic ratio of consumed water and foods.

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.

Previous case studies have reconstructed the isotopic life histories, often of high-status individuals, by taking isotopic measurements from multiple tissues corresponding to specific life periods of an individual.
