The carbon (δ 13 C) and nitrogen (δ 15 N) isotopic compositions of bone and tooth collagen
provide a powerful tool for studying past biological, environmental, and cultural phenomena …

Isotopic analyses of collagen, the main protein preserved in subfossil bone and tooth, has
long provided a powerful tool for the reconstruction of ancient diets and environments …

Criteria are presented for the identification of diagenetic alteration of carbon and nitrogen
isotope ratios of bone and tooth collagen prepared by a widely used method. Measurements …

We compare two methods of isolating bone collagen for stable carbon and nitrogen isotope
analysis. The older method (as practised at the University of Cape Town) demineralizes …

Stable carbon isotope analysis of archaeological human bone collagen is becoming
increasingly useful in diet reconstructions. This paper describes, for archaeologists, the …

Preferential preservation of noncollagenous proteins (NCP) in diagenetically altered bone
will affect amino acid compositions, inflate DL aspartic acid ratios, and increase CN ratios …

The quality of bone collagen extracts is central to the14C dating and isotope palaeodietary
analysis of bone. The intactness and purity of the extracted gelatin (“collagen”) is strongly …

Studies on Holocene periods in France and Liguria over the past 15 years provide an
important isotopic database (δ 13 C and δ 15 N) on human and animal bone collagen …

Stable nitrogen isotope analysis is a fundamental tool in assessing dietary preferences and
trophic positions within contemporary and ancient ecosystems. In order to assess more fully …

Two different collagen extraction methods were tested to compare their effects on the amino
acid composition and lipid content of the sample. Lipids were extracted from modern and …
