The identification of human food remains from archaeological sites contributes to paleonutrition and paleoepidemiology studies, shedding light on key aspects of human biological evolution and cultural changes.In the present study,macroscopic and microscopic food remains were recovered from human coprolites from Furna do Estrago,Pernambuco State,Brazil.The remains are dated between 1860 +/- 50 (BETA 145954) and 1,610 +/- 70 (BETA 145955) years BP (before present).The region may have been...
A Bayesian model sensitivity study of non-static diet-collagen isotope fractionations factors used to assess breastfeeding and weaning practices among fisher-gatherers populations, western Cuba (2017)
Reconstructing paleo-diets from bone-collagen isotope values (carbon and nitrogen) requires proper knowledge of diet-collagen isotopic fractionations (∆d13Cdiet-col, ∆d15Ndiet-col). While these isotopic fractionations vary considerably among previous human paleo-diet reconstructions, some more recent studies have successfully employed "non-static" dietary offsets. New research suggests that non-static diet-collagen isotope fractionations is best when attempting to reconstruct paleo-diets of...
Carbon and Nitrogen isotopic analysis on human and animal bones of Nanwa site, Henan Province, China (2017)
The Nanwa site（1680BC-Song Dynasty; located in Dengfeng city, Henan Province, China, provided a valuable opportunity for the Xia Dynasty and the Chinese civilization investigation. We could provide effective evidence for the food resources utilize pattern and agricultural economy development. Stable isotopic carbon, nitrogen analysis of 14 animals and 22 human bone collagen from the Nanwa site indicated that, wild animals (-19.9‰, 4.4‰, n=1) have a C3-based terrestrial diet. Domesticated pigs...
Diet and Adaptations in a High Altitude Rockshelter of Southern Peru, Based on Stable Carbon and Nitrogen Isotopes (2017)
We present the results of stable carbon and nitrogen isotope analyses made on well-preserved collagen of four Early and one Middle Holocene adult humans together with coeval faunal remains of Cuncaicha rockshelter in the Peruvian puna to determine paleodiet. In addition, we reconstruct important aspects of the ecology of the Pucuncho Basin, in which Cuncaicha is located, using new as well as already available and secured values for stable carbon and nitrogen of archaeological and modern fauna...
Diet and mobility on the Canadian Plateau: Isotopic analysis of domestic dogs and other fauna from the Bridge River site (2017)
This study reports on carbon, nitrogen, and sulphur isotope analyses of dog remains and other fauna from the Bridge River site in the Mid-Fraser region of the Canadian Plateau. We discuss these results in relation to dietary variability and resource mobility through time and in the relationships between dogs and humans. While dogs are not a direct proxy for humans in dietary isotope studies, their diets are influenced by human dietary practices, and therefore indicative of human subsistence...
Diet in Coastal Arequipa, Peru, at the Dawn of the Wari Empire (2017)
Excavations at Uraca, a cemetery in the Majes Valley, Arequipa, Peru, uncovered incomplete human skeletons (MNI = 157) and associated grave goods dating to the Early Intermediate Period and the early Middle Horizon. Interpersonal violence was omnipresent at Uraca: 67 of 100 adults suffered cranial wounds (7 were insults received around the time of death), and 20 individuals were violently decapitated and/or defleshed after death. AMS dates show the individuals buried at Uraca lived from...
Dietary shift and cultural evolution relation to intercontinental cultural exchanges and climate change in the Hehuang and contiguous regions, northwest China ~3600 years ago: Evidence from Carbon and Nitrogen Stable Isotopic Analysis (2015)
This study traces the extent to which dietary change coincides with intercontinental cultural exchanges in Eurasia, to enhance understanding of the effects of long-distance exchanges on the human diets. Through stable carbon and nitrogen isotope analysis of late Neolithic and early Bronze Age human and animal bone collagen, we find that intercontinental cultural exchanges in Eurasia led to significant changes in diet in the Hehuang and contiguous regions of northwest China. The isotopic evidence...
"Feeding the Dead" at Chiribaya Alta (2015)
The inclusion of foods and eating utensils within graves at Chiribaya Alta, a Late Intermediate site ~5 km from the mouth of the Osmore river, Peru suggests that "feeding the dead" during funerary rites was a common practice within the Chiribaya polity. Thus far, however, these foods have not been systematically considered in relation to funerary practices. This study examines food items placed within tombs at Chiribaya Alta (n=307) and considers their potential symbolic meanings within funerary...
Isotopic Perspectives on Spatial and Temporal Variability in British Columbia Paleodiet (2017)
This study aggregates and re-evaluates all available stable isotope data from archaeological human remains in British Columbia. Isotope signatures for coastal individuals correspond well with the heavy marine specialization attested to by archaeological and ethnographic studies of traditional Northwest Coast diets. Within this marine specialization, the data for coastal BC demonstrate a high degree of regional dietary variability, although high trophic level marine prey species are of ubiquitous...
Paleodiet in the Atacama Desert (Arica, Chile) and Andean Highlands (Ayacucho Basin, Peru) Using Stable Isotope Analyses of Dental Calculus (2017)
Long-considered a nuisance, dental calculus has recently enjoyed attention as a potentially useful alternative biomaterial for a variety of anthropological applications, including stable isotope analysis as a technique to study paleodiet. Carbon and nitrogen stable isotopes of dental calculus have been measured for populations near Arica, Chile in the Atacama Desert (Archaic-Late Intermediate period), and post-Wari (Late Intermediate Period) populations from the Ayacucho Basin, Peru in the...
Reconstructing ancient Maya nursing behavior and children's diets at Tikal, Guatemala (2017)
We examine the ancient Maya nursing practices and children’s diets at the archaeological metropolis of Tikal, Guatemala, through stable isotopic analysis of permanent teeth in adult skeletons. Stable carbon isotope analysis of tooth enamel permits a measure of the relative amount of carbon from maize foods in the diet, and helps track the introduction of solid foods into the children’s diet. Stable oxygen isotopes in tooth enamel reflect the sources of water that children consumed, and shed...
Reconstruction of diet and mobility patterns in human remains, bone and teeth, from a mortuary cave (Cueva de la Sepultura) in Tamaulipas, northeastern Mexico through stable isotope analysis (2017)
Bone and teeth were analyzed from multiple burials from a mortuary cave in the North of Mexico, dated around 1400 and 400 BC. Samples from 14 jawbones were analyzed to obtain the δ13C and δ15N of the bone collagen as well as δ13C and δ18O in bone bioapatite; M2 or M3 from the jawbones were cut into a series of layers to obtain multiple isotopic signatures from enamel, structural carbonate and collagen from the dentine of each tooth, representing different periods in the life of the individual....
Stable isotope analysis of animal diets at the Postclassic regional capital of Mayapan (2017)
Subsistence economies during the Postclassic Period (ca. AD 1000-1524) in the northern Maya lowlands were shaped by a range of strategies that included agriculture, the cultivation of wild plants, hunting, trade and market exchange, and the management of animals. Stable isotope data from archaeological faunal remains offer important dietary information to reconstruct the subsistence strategies during this period. In this paper, we present paleodietary data from faunal remains recovered from...
Stable Isotope Perspectives on Intra-Community Sharing (2017)
Stable isotope analyses of human skeletal tissues provide estimates of paleodiet at the scale of the individual. This paper explores intra- and inter-community variation in stable nitrogen, carbon, and sulfur isotopes in human bone and teeth as insight into the prevalence of food sharing in several ancient hunter-gatherer burial populations in California. The goal, in particular, is to trace intra-community variation over time to examine how cooperative foraging and food-sharing strategies...
