18 Hominin Paleodiets: The Contribution of Stable Isotopes
2007Stable isotope ratio analysis is now regularly used to investigate early hominin diets based upon the principle that ‘you are what you eat’. Analysis of collagen from Neanderthals and anatomically modern humans prior to 20 Ka has shown them to be significantly enriched in N compared to contemporaneous carnivores and herbivores.

Migration and Viking Dublin: paleomobility and paleodiet through isotopic analyses
Journal of Archaeological Science, 2012Abstract During the early medieval period in Ireland, Dublin was established as the largest Viking settlement on the island in the ninth century AD. A previous biodistance study has suggested that the population of the town consisted of a polyethnic amalgam of immigrant and indigenous.

Human biology in the Classic Maya collapse: Evidence from paleopathology and paleodiet
Journal of World Prehistory, 1996We review evidence from human biology—paleopathological and isotopic paleodietary studies on ancient Maya skeletons—to assess the validity of ecological models of the Classic Maya collapse, in which elevated disease and deteriorating diet are commonly assumed. To be upheld, the health arguments of ecological models require that the Maya disease burden (

HUMAN DIETARY COMPLEXITY IN TIANSHAN REGION AND THE INFLUENCE OF CLIMATE ON HUMAN PALEODIET
Radiocarbon, 2020ABSTRACTWith the popularization of carbon and nitrogen stable-isotope analysis methods used on archaeological samples from Xinjiang, the ancient paleodiet there has been revealed. However, research about isotopic analysis combined with environmental factors is rare, especially in such a variable and complex climate as that of the Tianshan region.

Stable Isotope Evidence for Maize Horticulture and Paleodiet in Southern Ontario, Canada
American Antiquity, 1995This paper reports new data on stable carbon and nitrogen isotopes obtained from human skeletal remains found at six prehistoric sites dating between A.D. 400 and 1500 in southern Ontario. Analyses examine more closely the timing and intensity of maize adoption and the importance of animal protein in the diet, adding to earlier work in the region by ...

Bone is one of the few materials that are consistently recovered from archaeological and paleontological sites; its chemical composition has the potential to provide valuable information about ancient human and faunal diet and health status. Diet is one aspect of the development of human culture; changes in dietary regimes occurred together with ...

Isotopic insight on paleodiet of extinct Pleistocene megafaunal Xenarthrans from Argentina
Gondwana Research, 2017Abstract The diet of extinct giant Xenarthrans is a debated topic, especially for ground sloths, for which herbivory, insectivory, and carnivory through scavenging or active hunting have been suggested. In this study, stable carbon isotopic composition of collagen and carbonate fraction of well-preserved fossil bones was used as a tracer of trophic ...

Reconstructing the Paleodiet of the Punic inhabitants at the site of Kerkouane (Tunisia)
2022Abstract: The proposed project intends to investigate the dietary system of the Punic population at Kerkouane, Tunisia. The cutting-edge approach of stable carbon and nitrogen isotopes analysis of human bones will allow us to assess the subsistence pattern of the past population.

Some Biochemical Aspects of Carbon Isotopic Paleodiet Studies
2006Carbon isotope ratios of preserved human tissues (collagen and carbonate in bone/tooth apatite) are used as indicators of the sources of nutrients in human populations. We discuss the possible roles of some biochemical phenomena in determining the partitioning of isotopically labeled nutrients in these tissues. Respiration converts all nutrient-derived
