Cutmark systematics: Analyzing morphometrics and spatial patterning at Palangana

Cutmarks have played an important role in addressing whether our hominid ancestors were hunters or scavengers, describing ritual modification of human bone, defining the origin of metallurgy, and highlighting the diversity of prehistoric butchering behavior. The widespread occurrence of cutmarks on animal bones and their variability allows archaeologists to use this kind of evidence to address a broad range of questions. One goal in examining cutmark diversity is to identify diagnostic cutmarks of prehistoric butchering, processing, and consuming behaviors. Linking cutmarks to specific activities allows us to test fine-grained hypotheses concerning the nature of an archaeological site, and to do this a systematic method for addressing variability in both the appearance and anatomical position of cutmarks is essential. An analysis of caribou bones collected by Lewis Binford from the Palangana site in Alaska is used to build and test a diagnostic cutmark classification using their morphometric and spatial properties. This case study demonstrates that cutmarks can be used to simultaneously address large-scale anthropological questions and reveal intra-site behavioral variability in the archaeological record.     

A cautionary note on the use of captive carnivores to model wild predator behavior: a comparison of bone modification patterns on long bones by captive and wild lions

A study with wild lions in Tarangire National Park (Tanzania) and with captive lions in Cabárceno Reserve (Spain) has yielded two different bone modification patterns, probably as a result of the differences in environmental contexts. Captive lions have modified bones more intensively, both in the form of total number of tooth-marked bones and number of tooth marks per tooth-marked bone, probably because of stereotypic behaviors. This emphasizes the importance of environmental contexts to understand carnivore behavior and their resulting bone modification patterns. It also shows that analogical models based on experiments carried out with captive carnivores may be biased and inadequate as proxies for wild carnivore bone modification behaviors.     

Reconstructing Life Histories Using Multi‐Tissue Isotope Analysis of Commingled Remains from St Stephen's Monastery in Jerusalem: Limitations and Potential

The examination of isotope ratios from multiple tissues offers new life to interpretations of commingled assemblages where information regarding individual biological history has been lost. Here, life histories from a commingled sample of Byzantine monks were reconstructed using enamel and bone δ¹³C and δ¹⁵N values. The δ¹³C values suggest a diet dominated by C₃ products, while the δ¹⁵N ratios indicate variable contributions of animal protein. After correcting for tissue‐specific enrichment factors, bone δ¹³C values were significantly enriched over enamel; this may be due to an increase in protein consumption, but could also reflect structural differences between tissues or correction factors used to compare these data.     

Cross-cultural interaction on Wuvulu Island,Papua New Guinea: the perspective from use-wear and residue analyses of turtle bone artifacts

Recent studies have emphasized the importance of Indigenous producers and traders in the formation of ethnographic museum collections, but have found difficulty in finding concrete evidence for their active roles. A use-wear and residue study of turtle bone cleavers from Wuvulu Island, Papua New Guinea provides the opportunity to test whether objects that comprise a significant component of early collections were made specifically for sale, as hypothesized by contemporary observers in the late 19th century. Comparative studies of used and unused turtle bone artifacts from the Caroline Islands and Papua New Guinea identified differences between wear traces resulting from manufacture and use. Analyses of the Wuvulu turtle bone cleavers showed they had been heavily used prior to sale. Rather than produce artifacts to meet the high demand from German traders, the local people sold old, worn-out objects, many of which had been repaired. The study demonstrates that archaeological approaches to ethnographic museum collections can trace Indigenous agency within cross-cultural interaction. It also showcases the potential of use-wear and residue analytical techniques for the analysis of bone tools and the utility of digital, hand-held microscopes for the analysis of large artifacts.     

Stable isotopic analysis of human bones from Jiahu site,Henan, China: implications for the transition to agriculture

We have investigated change in subsistence during the transition to agriculture in the site of Jiahu, Henan Province, China, using stable isotopic analysis of collagen and apatite in human bones. Millet agriculture is well documented at drier high latitudes of the Yellow River Valley, while rice agriculture predominated at wetter lower latitudes of the Yangtze Valley region. The early Neolithic site of Jiahu lies near the boundary between the drier north and wetter south. Archaeobotanical evidence shows that rice was a significant component of diet at Jiahu, but its δ¹³C value is similar to that of other foods, and therefore cannot be conclusively identified by carbon isotope analysis. Foxtail and broomcorn millets are the only C₄ crops known for the Chinese Neolithic. Because of their high δ¹³C values, their consumption can be evaluated by stable carbon isotope analysis of human bone. Collagen reflects mainly the δ¹³C value of dietary protein, and apatite accurately records that of the whole diet. Isotopic analysis of 15 well-preserved samples from three periods shows that collagen δ¹³C values were very low for almost all individuals, suggesting C₃-based foods dominated their diets. However, apatite carbonate δ¹³C values and δ¹³C spacing between collagen and apatite (Δ¹³C_ap-co) indicate that millet may have been a minor component of the diet in this region. Individuals, who consumed the smallest amounts of animal protein, as indicated by low δ¹⁵N, generally had the highest apatite δ¹³C values. Archaeobotanical evidence for millet at Jiahu is needed to support this interpretation.     

Strontium and stable isotope evidence for diet and mobility in Roman Gloucester,UK

This paper presents the results of a multi-isotopic (oxygen, strontium, carbon and nitrogen isotopes) investigation of population and dietary diversity in Roman Gloucester, focusing on individuals found in a late 2nd century AD mass burial pit at London Road, and comparing them to those found in the nearby cemetery. There were no statistical differences in isotopic composition between mass grave and cemetery burials, suggesting, in agreement with the osteological evidence, that the mass burial was the result of a catastrophic event, probably an epidemic disease. Strontium and oxygen isotope analysis demonstrated considerable diversity in the origins of the Gloucester population, with evidence for both UK and non-UK individuals. Diet was predominately terrestrial and similar to that of other Romano-British populations. Elevated δ¹³C_dentine ratios in some individuals are correlated with raised δ¹⁸O_p values and are therefore probably due to childhoods spent in warmer climates, rather than dietary variation.     

Zooarchaeological perspectives on the Chinese Early and Late Paleolithic from the Ma’anshan site (Guizhou,South China)

Ma’anshan is a Paleolithic cave site in the Guizhou province of southern China. The total area of the excavations is ca. 48 m², and the cultural deposit is divided into two layers representing the Chinese Late Paleolithic and the later part of the Early Paleolithic. The upper layer dates between 19,295  BP and 31,155 BP by AMS technique, and the lower layer is dated to around 53,000 BP by U-Series technique. Thousands of bone fragments were recovered from the two layers. Species abundance, bone surface modifications, skeletal element representation, and mortality patterns were studied in an investigation of assemblage formation history and patterns of prey selection and meat consumption by hominins. Interpretations of the faunal data are strengthened by reference to experimental studies and ethnoarchaeological data. The zooarchaeological data indicate that the later occupants of Ma’anshan Cave hunted mainly medium and small game animals, while the earlier occupants tended to prey upon larger animals. In the later period, hominins also made fuller use of the carcasses. The breadth of the meat diet increased with time, due to the inclusion of quick small animals (bamboo rats and birds) in the later period. The differences between the two faunal assemblages are consistent with the chronologic boundary currently drawn between the Chinese Early and Late Paleolithic ca. 30–27 ka BP, based on technological and other evidence.
