Bone Collagen Quality Indicators for Palaeodietary and Radiocarbon Measurements
TL;DR: In this article, chemical, elemental and isotopic parameters for the assessment of collagen quality are discussed, and it is concluded that there is no unequivocal way to detect natural levels of contamination with the discussed parameters, although their use can identify many cases.

Experimental Evidence for the Relationship of the Carbon Isotope Ratios of Whole Diet and Dietary Protein to Those of Bone Collagen and Carbonate
Stanley H. Ambrose,Lynette Norr +1 more
TL;DR: The use of stable carbon isotopes for diet reconstruction is predicated on the assumption that the carbon isotopic composition of animal tissues is assumed to be a direct and constant function of the diet.

Stable isotopes of carbon and nitrogen in the study of avian and mammalian trophic ecology
TL;DR: Differences in stable-isotope composition among trophic groups were detected despite variation attributable to geographic location, climate, and analytical techniques, indicating that these effects are large and pervasive.

Trophic Level Isotopic Enrichment of Carbon and Nitrogen in Bone Collagen: Case Studies from Recent and Ancient Terrestrial Ecosystems
TL;DR: Several case studies of ancient vertebrate communities from Upper Palaeolithic sites in southwestern France are presented to check whether the enrichment values estimated for these past ecosystems are consistent with those measured in well-monitored modern ecosystems.

Effect of Diet Quality and Composition on the Isotopic Composition of Respiratory CO2, Bone Collagen, Bioapatite, and Soft Tissues
Larry L. Tieszen,Tim Fagre +1 more
TL;DR: Lee-Thorp et al. as mentioned in this paper used bioapatite CO3 as a supplement to collagen, especially in bones older than 10000 years, and as an adjunct to collagen for estimates of carnivory.

Postmortem preservation and alteration of in vivo bone collagen isotope ratios in relation to palaeodietary reconstruction
TL;DR: In this article, the authors present the first examination of the validity of this assumption and show that postmortem alteration of bone collagen isotope ratios does occur, but that it is possible to identify prehistoric bones whose collagen has not undergone such alteration.

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.

New Method of Collagen Extraction for Radiocarbon Dating
TL;DR: There are, however, frequent and often important errors in 14C bone measurements which arise chiefly because of the difficulty of eliminating completely the numerous pollutants during chemical treatment.

Improved collagen extraction by modified Longin method
TL;DR: In this article, a re-evaluation of the Longin collagen extraction method shows that a lower reflux temperature reduces degradation of protein ("collagen") remnants, which allows additional purification through ultrafiltration to isolate the >30kDalton fraction of the reflux product.
