Bone chemistry and bioarchaeology

Isotopic analysis of bones and teeth is now routinely used for dating skeletons and archaeological sites, and for diet, climate, and habitat reconstruction. Techniques of radiocarbon dating of bones and teeth developed by Harold Krueger and others during the 1960s laid the groundwork for subsequent research on stable carbon, nitrogen, oxygen, and strontium isotope analysis. We first review salient points in the history of research in bone isotope biogeochemistry, focusing on Krueger's contributions. We then discuss the significance of contributions to this volume of the Journal of Anthropological Archaeology for the current state of research in dietary and environmental reconstruction in archaeology, bioarchaeology, and paleoanthropology. All papers in this volume include isotopic analysis of the carbonate phase of bone and/or tooth enamel apatite for dietary and/or environmental reconstruction. Harold Krueger was instrumental in developing methods of apatite purification for removing diagenetic phases, isotopic analysis, and interpretive models of paleodiets. Apatite isotopic analysis is now an important area of bone biogeochemistry research that provides powerful tools for reconstructing human behavior in the emerging anthropological discipline of bioarchaeology.
