Sulfur isotope analysis of collagen
Sulfur isotopes ( δ 3 4 S values) have significant potential for addressing archaeological, paleontological, and paleoecological research questions. Studies of ancient materials rely on the assumption that δ 3 4 S values have been minimally altered by diagenesis , yet meaningful analyses of sulfur isotope preservation/alteration are rare. This paper has 3 objectives: (1) to review and revise previous approaches to evaluating sulfur isotope altera…
Archaeological Recovery of Late Pleistocene Hair and Environmental DNA from Interior Alaska
Ancient hair and remnant plant DNA are important environmental proxies that preserve for millennia in specific archaeological contexts. However, recovery has been rare from late Pleistocene sites and more may be found if deliberately sought. Once discovered, singular hair fragments are not easily identified to taxa through comparative analyses and environmental DNA (eDNA) extraction can be difficult depending on preservation or contamination. In …
Ancient DNA-based sex determination of bison hide moccasins indicates Promontory cave occupants selected female hides for footwear
The thirteenth-century human occupants of the Promontory caves, Utah, distinguished themselves from surrounding Fremont populations by being successful hunting specialists of bison in a region normally peripheral for that species. The hunters’ success is evident from the abundance of faunal remains excavated from the dry caves. The dry cave conditions also preserved hundreds of worn moccasins, which are of particular interest because of the Canad…
Isotopic Evidence for Long-Distance Connections of the AD Thirteenth-Century Promontory Caves Occupants
The Promontory caves (Utah) and Franktown Cave (Colorado) contain high-fidelity records of short-term occupations by groups with material culture connections to the Subarctic/Northern Plains. This research uses Promontory and Franktown bison dung, hair, hide, and bone collagen to establish local baseline carbon isotopic variability and identify leather from a distant source. The ankle wrap of one Promontory Cave 1 moccasin had a δ13C value that i…
Do Uncharred Plants Preserve Original Carbon and Nitrogen Isotope Compositions
Pleistocene Hairs
Pleistocene hairs can provide significant insights into the peopling of the Americas through isotopic and genetic analysis. Microscopic identification of isolated hairs in coprolites or sediments typically exposes hairs to mounting and/or casting media that might alter stable isotope, radiocarbon, trace element, and ancient DNA results. This paper tests the effects of such contaminants on stable carbon and nitrogen isotope analyses of hair, and d…
Best practices for calibrating and reporting stable isotope measurements in archaeology

Environmental change and seasonal behavior of mastodons in the Great Lakes region inferred from stable isotope analysis
We investigate seasonal variations in the diet and drinking water of four Great Lakes mastodon ( Mammut americanum ) specimens using stable isotope analysis of serially sampled inner-enamel bioapatite structural carbonate (δ 13 C sc , δ 18 O sc ), and previously published bulk analyses. Isotopic analyses and thin section measurements showed that mastodon tooth enamel extension rates (~ 12–4 mm/yr, decreasing toward the cervix) were lower than tho…
Mammoth tooth enamel growth rates inferred from stable isotope analysis and histology
Mammoth ( Mammuthus sp .) teeth are relatively abundant in Quaternary deposits from Eurasia and North America, and their isotopic compositions can be used to reconstruct past seasonal patterns in precipitation, diet, and migration. Strategies for collecting and interpreting such data, however, are strongly dependent on growth rates, which can vary among species, individuals, and within teeth. In this study, we use histological and isotopic measur…
Isotopic Evidence for Diet at Chau Hiix, Belize
The stable carbon and nitrogen isotope values (δ13C, δ15N) of collagen and the carbon isotope value of structural carbonate in bioapatite were measured in the bones and teeth of Early Classic to Historic period Maya buried at Chau Hiix, Belize. Diet at Chau Hiix comprised a mixture of resources but contained an unusual amount of protein from high trophic levels. There were no differences between the diets of males and females, and there were no c…
