The Analysis of a Late Holocene Bison Skull from the Ashley National Forest, Utah (2004)
DOCUMENT Full-Text Kenneth P. Cannon.

In 2003 a partial bison skull was recovered by Ashley National Forest archeologist Brian Storm from an elevation of 3840 m (12,600 ft) AMSL in the Uinta Mountains. The partial skull consists of a portion of the frontal, occipital region, and horn cores including horn sheaths. The presence of the horn sheaths is of particular interest for the ecological information they can provide. Through the analysis of the individual cones of the horn sheath a record of the animal’s dietary and migration...


Ancient Human-Animal Interactions in Chachapoyas Region: Isotopic Analysis of Zooarchaeological Remains from Kuelap, Peru (2018)
DOCUMENT Citation Only Samantha Michell. Jennifer Marla Toyne. Alfredo Narvaez. Victor Vasquez.

This study uses isotopic analysis of fauna remains as a proxy for reconstructing the ancient Chachapoya environment of the northeastern highlands in Peru. Large middens have been excavated at the monumental center of Kuelap (900-1535 CE), yet there is little previous research focused on the fauna remains at this or other archaeological contexts in the region. The goal of this project was to reconstruct animal resource exploitation and provide insight into dietary variation and environment at...

DOCUMENT Citation Only Ariana Gugora. Tosha Dupras. Erzsébet Fóthi.

Between 2005 and 2009, archaeologists excavated more than 100 skeletons from the medieval (1240s AD) Hungarian site of Solt-Tételhegy. Little has been published about this archaeological settlement, and although previous stable isotopic research has described the migration patterns of medieval European peoples, here we present the first such study performed on a medieval Hungarian population. Stable oxygen isotope analysis was conducted on dental enamel from 23 individuals and on bone apatite...


Childhood Diets and Residential Mobility in the Late Intermediate Period, Colca Valley, Peru: A Study of Carbon and Oxygen Isotope Ratios from Dental Apatite (2017)
DOCUMENT Citation Only Matthew Velasco. Loro Qianhui Pi. Tiffiny A. Tung.

Around AD 1300 in the Colca Valley of southern Peru, an increasing proportion of elite individuals began to mark themselves as ethnically distinct by elongating the heads of children. This permanent act had far-reaching effects on the livelihoods of modified individuals, especially females, who exhibit more diversified diets in adulthood and experienced lower rates of cranial trauma. The present study complements prior stable isotopic analysis of bone collagen by examining carbon and oxygen...


A Combined Bioarchaeological and Isotopic Approach to Understanding the Regional Diversity and Population Mobility within the Holmul Region, Guatemala (2015)
DOCUMENT Citation Only Aviva Cormier.

The northeastern Petén of Guatemala is an ideal area for applying stable isotope analysis to reconstruct past population histories and to explore the interplay of migration and social complexity throughout the rise of the Maya. The strontium and oxygen isotope analysis of dental enamel is a productive alternative when bone collagen is not available or is severely altered by taphonomic processes or conditions of preservation. These isotopic analyses of dental enamel can be combined with...


Deviance in youth: Anomalous nitrogen and carbon isotopic values among individual subadults at Medieval Alytus, Lithuania (2015)
DOCUMENT Citation Only Katherine Page. Tosha Dupras. Rimantas Jankauskas. Lana Williams. Courtney Eleazer.

Rapid turnover of bone collagen δ13C and δ15N values in subadults can reveal dietary and physiological changes experienced by illuminating chronic stress not apparent as skeletal, pathological lesions. To assess subadult morbidity and mortality in Medieval Alytus, Lithuania, an osteobiographical examination was undertaken of individuals who presented humeral isotopic values ± 2σ from sample and cohort means (-20.02 ± 0.43‰; 11.09 ± 1.21‰). Four infants (0.1-2.9 years) and four juveniles (5-11.9...

DOCUMENT Citation Only Jacklyn Rumberger. Sarah Barber. Arthur Joyce. Tosha Dupras. Stacie King.

This study reports on diet and mobility among people living in the lower Río Verde Valley, Oaxaca, Mexico, during the Late Classic (AD 500-800) and Early Postclassic (AD 800-1200) periods, specifically focusing on how political and social collapse affected subsistence practices, diet, and human migration. Archaeological evidence suggests that Río Viejo, the region’s largest urban center before AD 800, experienced multiple periods of political fragmentation and instability during its long...


Diet and mobility on the Canadian Plateau: Isotopic analysis of domestic dogs and other fauna from the Bridge River site (2017)
DOCUMENT Citation Only Alejandra Diaz. Anna Marie Prentiss. Rebecca Macdonald. Olaf Nehlich. Michael Richards.

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)
DOCUMENT Citation Only Beth K. Scaffidi. Natasha P. Vang. Tiffiny A. Tung.

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 variability through isotopic analysis of modern human hair from Nicaragua: exploring significant differences in diet between and among demographic groups in a single population (2017)
DOCUMENT Citation Only Catherine G. Cooper. Angela Perri. Jessica L. Burns. Jeremy M. Koster. Michael P. Richards.

Carbon and nitrogen stable isotope analysis of modern human hair from Nicaragua was used to explore what constitutes significant differences in gross diet between and among demographic groups within the same population. Our results show that the absolute differences between isotopic central tendencies of demographic groups are small, but some are significant. Socioeconomic categories that were found to have significantly different isotopic signatures between or among groups included age groups...


Dietary variation at Paquimé (Casas Grandes) and Convento sites: Evidence from the stable isotope analysis of human bone collagen (2016)
DOCUMENT Citation Only Courtney McConnan Borstad. Jane Kelley. M. Anne Katzenberg.

Paquimé (Casas Grandes), located in northern Mexico, is well known for its Medio period (AD 1200-1450) monumental architecture and the variation apparent in its mortuary practices. While previous bioarcheological studies have addressed a wide range of questions, dietary practices at Paquimé still remain largely unexplored. Stable isotope analysis of bone collagen is one technique that can directly reconstruct diets at Paquimé and identify differences between individuals, time periods, and...


Documenting Dietary Effects of Imperial Collapse and Drought: Bioarchaeology and Stable Isotope Analysis at Huari-Vegachayoq Moqo, Peru (2017)
DOCUMENT Citation Only Taylor MacDonald. Natasha P. Vang. Tiffiny A. Tung.

This study examines the diets of 32 individuals who were deposited in the Vegachayoq Moqo sector at the site of Huari, the capital of the Wari Empire. The commingled skeletal remains date to the second half of the Late Intermediate Period (LIP), long after the empire’s collapse circa 1100 CE. This was also a time of an extended drought. The diets, reconstructed from carbon and nitrogen stable isotopes from bone collagen, are compared among the individuals and to those of earlier Wari populations...


Early Pastoralists in Tanzania: Mobility and the Seasonal Round (2018)
DOCUMENT Citation Only Anneke Janzen. Mary Prendergast. Katherine Grillo.

First developing around 8,000 years ago, pastoralism in Africa has continued as a flexible and dynamic mode of subsistence. One key feature of this dynamism is mobility, which is crucial for many East African pastoralists today to access seasonally available pasture and water. In areas of unpredictable rainfall, mobile pastoralism permits more people to live in dry lands than do other subsistence strategies. How the earliest herders in Tanzania used the landscape is still relatively unknown....


Ecology of Bison in the Greater Yellowstone Ecosystem (2018)
DOCUMENT Citation Only Kenneth Cannon.

Bringing the geologically historic record to bear on questions of ecosystem evolution is a goal emphasized in recent National Research Council reports. Within this context one species has become significant, the bison of the Greater Yellowstone Ecosystem. Recent expansion of the population, and its subsequent migration outside federal lands, has created concern among federal managers, local ranchers, and conservation groups. However, much of what is known about pre-management herds is based...


The Elite Meroitic Necropolis of Sai Island, Part II: Bioarchaeological Interpretations (2017)
DOCUMENT Citation Only Tosha Dupras. Vincent Francigny. Amanda Groff. Alex de Voogt.

Five Meroitic necropoli have been identified on Sai Island, located in northern Sudan between the 2nd and 3rd Nile cataracts. Recent archaeological excavations conducted by the French Unit of the National Corporation for Antiquities and Museums have focused on a small elite Meroitic necropolis (300BC-350AD). Although the archaeology of this necropolis is complicated by interments from other periods and looting, here we present the initial analyses of the Meroitic elite skeletal remains in...

DOCUMENT Citation Only Jonathan Wong. Andrew Somerville. Margaret J. Schoeninger.

Stable isotope analysis of faunal bone can provide valuable information about the environments in which the animals lived. Reconstructing paleoenvironments at archaeological sites permits a better understanding of the factors that influenced their social development and decline. In this poster we present results of stable isotopic analyses (d13Capatite, d18Oapatite, d13Ccollagen and d15Ncollagen) of leporid bone apatite and collagen to investigate temporal changes in environmental conditions at...


Escaping Collapse in Northwest Mexico: Social and Environmental Factors of Resiliency at La Ferrería, Durango, Mexico (2016)
DOCUMENT Citation Only Andrew Somerville. Jose Luis Punzo Díaz.

The end of the Mesoamerican Classic Period (ca. AD 900) was a time characterized by widespread social change, political upheaval, and broad regional drought conditions. In Northwest Mexico, several large centers such as La Quemada and Alta Vista were abandoned and never reoccupied. The site of La Ferrería in the Guadiana Valley of Durango, however, remained an important site for several centuries into the Postclassic Period. This presentation explores the social and environmental factors that...


Evaluating the Utility of Using Stable Oxygen Isotope Analysis to Study Ancient Migration and Climate Reconstruction in the Ayacucho Basin of Peru (2016)
DOCUMENT Citation Only Tiffiny Tung. Theresa Miller. Jessica Oster. Larisa DeSantis.

This study examines whether oxygen isotope analysis can be used to study ancient human migration in the central, highland Andes of Peru (Ayacucho Basin). Although strontium isotope analysis is a reliable way of exploring questions of migration, oxygen isotope analysis, which is significantly less expensive, may offer preliminary insights regarding the possible presence of migrants at a site. This approach has not yet been used in the Ayacucho Basin where the Wari empire was centered, so we...


Evidence for Close Management of Sheep in Ancient Central Asia: Foddering Techniques and Transhumance in the Final Bronze Age (2018)
DOCUMENT Citation Only Alicia Ventresca Miller.

Ancient animal management strategies have important implications for debates on modern pastoral landscape use in Eurasia. As livestock production intensifies in in semi-arid regions there is a need to identify the diverse set of strategies employed by pastoralists. Sequential carbon (δ13C) and oxygen (δ18O) isotope analysis of teeth from domesticated sheep at Bronze Age sites in Kazakhstan exhibit varied isotopic sequences. Sheep from Kent exhibit an inverse relationship where low δ18O values...


Exploring Human-Canid Interactions among the Dorset Using Stable Carbon and Nitrogen Isotope Analysis (2015)
DOCUMENT Citation Only Alison Harris. Vaughan Grimes.

The scarcity of clearly identifiable dog bones and artifacts associated with dogsled traction has led many archaeologists to posit that the Dorset did not keep domestic dogs. While this statement has implications for the ability of the Dorset to cope with the variability of the arctic environment, it may also be an oversimplification of the problem. Canid remains do occur on Dorset sites, albeit in low numbers, but they are not identifiable to species based on skeletal morphology alone due to...


Exploring sex-based variation in infant feeding practices in Byzantine Greece using stable isotope analysis of dentin serial sections (2017)
DOCUMENT Citation Only Cynthia Kwok. Sandra Garvie-Lok. M. Anne Katzenberg.

This paper explores whether sex-based differences in infant feeding practices existed at the early Byzantine Greek site of Nemea (5th-6th c.). Dentin serial sections were obtained from the permanent first molar and first premolar from 31 adults (11 males, 8 females, 12 unidentified) and analyzed for stable carbon and nitrogen isotopes. The isotopic data demonstrated that most individuals were breastfed and fully weaned at a mean age of 2.6 with a range of 1.8 to 3.6 years. Sex-based differences...
