Journal ArticleDOI
Nitrogen and carbon isotopic composition of bone collagen from marine and terrestrial animals
TL;DR: Results indicate that bone collagen δ15N values will be useful in determining relative dependence on marine and terrestrial food sources and in investigating trophic level relationships among different animal species within an ecosystem.
Journal ArticleDOI
Burnt bones and teeth: an experimental study of color, morphology, crystal structure and shrinkage
TL;DR: In this article, the effects of experimental, controlled heating on modern bones and teeth from sheep and goats were investigated, and four aspects of heating specimens to between 20 and 940°C were considered: color, microscopic morphology, crystalline structure and shrinkage.
Journal ArticleDOI
Stable nitrogen isotope ratios of bone collagen reflect marine and terrestrial components of prehistoric human diet
TL;DR: The nitrogen isotope ratios of bone collagen from prehistoric inhabitants of the Bahamas are anomalously low for reasons that relate to the biogeochemical cycle of nitrogen in coral reefs.
Journal ArticleDOI
Stable isotope analyses in human nutritional ecology
TL;DR: This work presents one method based on stable isotope analysis in human tissues and discusses its contributions, and discusses several potential sources of variation including sex, age, nutritional status, among others.
Journal ArticleDOI
Altered states: effects of diagenesis on fossil tooth chemistry
TL;DR: A study of modern and fossil teeth from northern and central Kenya, using the ion micro- probe, electron microprobe, and transmission electron microscope, confirms that fossil tooth chemistry is controlled not only by the diagenetic precipitation of secondary minerals but also by the chemical alteration of the biogenic apatite as discussed by the authors.
