Death in the line of duty: late medieval burials at the site of Lepenski Vir,Serbia

Four late medieval burials were excavated at the site of Lepenski Vir in the Iron Gates Gorge, Serbia. One of the individuals, Lepenski Vir 62, exhibits evidence of a sharp‐force trauma on the left parietal, consistent with a combat wound. None of the other contemporaneous individuals show any evidence of trauma or other pathology on the few preserved bones. We argue that the skeletons belong to soldiers involved in the border warfare on the Danube which was quite common at the end of the 14^th and the first half of the 15^th century between Serbian, Hungarian and Turkish forces.

Causation and cleanliness: George Callender, wounds, and the debates over Listerism

This article reexamines the surgical and historiographic debate over antisepsis and the germ theory through the work of the prominent London surgeon George W. Callender (1830-1879) and the statistical records of St. Bartholomew's Hospital. Surgeons in the mid-nineteenth century faced a rising incidence of wound infection and its systemic complications. Examining mortality and complication rates by type of wound, however, suggests that the extent of this crisis is often overstated. Callender himself occupied a frequently overlooked middle ground in the debate over Listerism. On the one hand, his program of cleanliness, which antedated Lister's work and extended from the wound to the ward, produced excellent and influential results. On the other, while he was never an explicit critic of the germ theory, his writings demonstrate why Lister's collapse of causation into a single etiologic agent was so difficult for surgeons to accept.     

Thermochemical and bacterial sulfate reduction in the Cambrian and Lower Ordovician carbonates in the Tazhong Area,Tarim Basin,NW China: evidence from fluid inclusions,C, S,and Sr isotopic data

Petrographic features, C, O, S, and Sr isotopes were determined, and fluid inclusions (FI) were analyzed on various stages of vug‐ and fracture‐fillings from the Cambrian and Lower Ordovician reservoirs in the Tazhong area, Tarim basin, NW China. The aim was to assess the origin of pyrite and anhydrite and the processes affecting sulfur during diagenesis of the carbonates. Pyrite from seven wells has δ³⁴S values from ?22‰ to +31‰. The pyrites with low δ³⁴S values from ?21.8‰ to ?12.3‰ were found close to fracture‐filling calcites with vapor‐liquid double‐phase aqueous fluid inclusions homogenization temperatures (FI‐Th) from 55.7 to 73.2°C, salinities from 1.4wt% to 6.59wt% NaCl equiv and δ¹³C values from ?2.3‰ to ?14.2‰, indicating an origin from bacterial sulfate reduction by organic matter. Other sulfides with heavier δ³⁴S values may have formed by thermochemical sulfate reduction (TSR) during two episodes. The earlier TSR in the Middle and Lower Cambrian resulted in pyrites and H₂S having δ³⁴S values from 30 to 33‰, close to those of bedded anhydrite and oilfield water (approximately 34‰). The later TSR is represented by calcites with δ¹³C values as light as ?17.7‰ and FI‐Th of about 120–145°C, and pyrite and H₂S with δ³⁴S values close to those of the Upper Cambrian burial‐diagenetic anhydrite (between +14.8‰ and +22.6‰). The values of the anhydrite are significantly lighter than contemporary seawater sulfates. This together with ⁸⁷Sr/⁸⁶Sr values of anhydrite and TSR calcites from 0.7091 to 0.7125 suggests a source from the underlying Ediacaran seawater sulfate and detrital Sr contribution.     

Mortuary Practices,Cultural Context,Bayesian Chronology,and Maize Consumption among Terminal Late Woodland Societies in Northeastern Illinois

In 1940, Gretchen Cutter and a WPA crew conducted excavations in the Mound Wi^o5 at the Fisher site in Will County, Illinois. We examined those materials as part of our reanalysis of the Fisher site excavations by George Langford and the University of Chicago. The mound’s material culture correlates with the Des Plaines phase but contains strong connections to the east, especially with Albee phase mortuary practices. Calibrated ¹⁴C dates and Bayesian modeling place the Des Plaines phase as contemporary with the Mound Wi^o5 mortuary’s primary use during the ninth to eleventh centuries. There is isotopic evidence of a mixed C₃/C₄ diet with some maize consumption. Mound Wi^o5 represents the only Terminal Late Woodland collective mortuary facility currently known in northeastern Illinois. The identification of such multigenerational communal Terminal Late Woodland mortuary practices lends support to the contention that they provided the cultural base for the emergence of the distinctive Langford Tradition accretional mortuary mounds.     

Geochronology of Palaeolithic cultures in the Hiran Valley, Saurashtra, India

The U and Th concentrations of 16 miliolite samples from the Hiran Valley in Saurashtra ranged from 0·3 to 2·14ppm and 0·12 to 0·82ppm respectively. The ²³⁴U/²³⁸U activity ratio ranged from 1·09 to 1·16, with a mean of 1·12±0·02. It agrees well with the seawater value of 1·14±0·02 within the quoted errors. Nine of the samples were datable by the ²³⁰Th/²³⁴U method and the ages ranged from 56·8 to 190 Kyr. The problem of chronology of Palaeolithic artifacts is interlinked with the miliolite and other coastal formations. The present investigations permit the development of a chronological framework for the Palaeolithic cultures in the Hiran Valley in particular, and generally in Saurashtra Peninsula. On the basis of radiometric dates and relative chronology, the Lower Palaeolithic cultures fall in a time-bracket of 190-69 Kyr bp. The Middle Palaeolithic industry is much older than 56·8 Kyr bp. The dates obtained for the Lower Palaeolithic cultures are perhaps the oldest reported to date.     

Palaeodiet at Eton College Rowing Course, Buckinghamshire: isotopic changes in human diet in the Neolithic, Bronze Age, Iron Age and Roman periods throughout the British Isles

Through isotopic investigations of directly dated human remains recovered from the Eton College Rowing Course, we examine changes in diet from the Neolithic to the Roman period. The human isotope signatures point to a diet based on C₃ terrestrial resources. A significant correlation is visible between human ??¹³C values and time, but no such trend is observed in ??¹⁵N. The animal isotope data from Eton are unevenly distributed, making it difficult to determine if the human values mirror the animal values. To assess whether the results from Eton are typical, we compare our results to isotope data from other British sites dating from the Neolithic to the Roman period. Across this time period, we see a strong correlation between the mean ??¹⁵N of the humans and that of the main domesticated herbivores, with an offset of ??4.5?? between the two. Thus, the changes in the human isotope values are likely linked to changes in the isotopic signatures of the herbivores rather than changes in the protein composition of human diets. By contrast, no clear temporal relationship is observed between the mean ??¹³C of the humans and that of the main domesticated herbivores, with an offset of ??1.4?? between the two. There is, however, a weak correlation observed between the mean ??¹³C of the humans and that of the cattle, which may account for some of the variation in human ??¹³C values between sites. The absence of a strong correlation between mean human and animal ??¹³C suggests that the primary factor influencing human ??¹³C values between sites is dietary composition. The lack of co-variation between ??¹³C and ??¹⁵N is likely to reflect the different representation of dietary macronutrients. Given that the nitrogen results suggest that the animal protein consumption patterns are similar across sites, the human ??¹³C variation between sites is likely to reflect the plant portion of the diet.     

Palaeolimnological impacts of early prehistoric farming at Lough Dargan,County Sligo,Ireland

This study provides a unique method of inquiry for archaeological investigation with an aim to assess the intensity and effects of Neolithic and Bronze Age farming practices at Lough Dargan, northwest Ireland, through a multi-proxy analysis of a lake sediment core. Chironomid (non-biting midge fly) subfossils and lake sediment geochemistry (δ¹³C, δ¹⁵N and C:N ratios) were used to assess changes in limnological conditions through time. The limnological data were compared with macroscopic charcoal concentration and pollen data to examine the potential influence that early farmers had on a freshwater lake system within a prehistorically active catchment. Results from the chironomid analysis show that the first substantial period of agricultural activity in the early Neolithic (c. 3730–3190 BC) resulted in a temporary shift to more eutrophic lake conditions. There is evidence of animal husbandry with substantial levels of animal waste reaching the lake, leaving an imprint in the geochemical record of increased δ¹⁵N values and decreased δ¹³C values and C:N ratios during this time. The chironomid community reverted back to its pre-impacted state c. 3190 BC in response to a period of reduced farming (c. 3390–3000 BC) which eventually led to a distinct lull in activity, with possible cessation of farming from 3000 to 2700 BC. A return to eutrophic conditions coincided with the gradual return of agriculture, with more permanently altered lake conditions dominating from 2400 BC, even during a 250-year period of reduced human activity commencing at c. 1440 BC. Increased sedimentation rate, along with increases in δ¹³C, δ¹⁵N and C:N, the presence of chironomid taxa indicative of erosion, more eutrophic lake conditions and high concentrations of macroscopic charcoal all point to more intensive land use practices during the Bronze Age. Palaeolimnological data exhibited an immediate response to intensified farming during this time, and were especially responsive to pastoral farming due either to scale of activity or proximity to the lakeside. The success of this study demonstrates the effectiveness of palaeolimnological analysis in the investigation of prehistoric farming. This approach will help inform Neolithic and Bronze Age land-use practice and human–environment relations in the region, and highlights the potential for chironomid-based archaeological research.     

Exploring the potential linkages between oil‐field brine reinjection,crystalline basement permeability,and triggered seismicity for the Dagger Draw Oil field,southeastern New Mexico,USA, using hydrologic modeling

We used hydrologic models to explore the potential linkages between oil‐field brine reinjection and increases in earthquake frequency (up to M_d 3.26) in southeastern New Mexico and to assess different injection management scenarios aimed at reducing the risk of triggered seismicity. Our analysis focuses on saline water reinjection into the basal Ellenburger Group beneath the Dagger Draw Oil field, Permian Basin. Increased seismic frequency (>M_d 2) began in 2001, 5 years after peak injection, at an average depth of 11 km within the basement 15 km to the west of the reinjection wells. We considered several scenarios including assigning an effective or bulk permeability value to the crystalline basement, including a conductive fault zone surrounded by tighter crystalline basement rocks, and allowing permeability to decay with depth. We initially adopted a 7 m (0.07 MPa) head increase as the threshold for triggered seismicity. Only two scenarios produced excess heads of 7m five years after peak injection. In the first, a hydraulic diffusivity of 0.1 m² s^?1 was assigned to the crystalline basement. In the second, a hydraulic diffusivity of 0.3 m² s^?1 was assigned to a conductive fault zone. If we had considered a wider range of threshold excess heads to be between 1 and 60 m, then the range of acceptable hydraulic diffusivities would have increased (between 0.1–0.01 m² s^?1 and 1–0.1 m² s^?1 for the bulk and fault zone scenarios, respectively). A permeability–depth decay model would have also satisfied the 5‐year time lag criterion. We also tested several injection management scenarios including redistributing injection volumes between various wells and lowering the total volume of injected fluids. Scenarios that reduced computed excess heads by over 50% within the crystalline basement resulted from reducing the total volume of reinjected fluids by a factor of 2 or more.     

Adding insult to injury: opportunistic treponemal disease in a scalping survivor

Although the taking of scalps is arguably a perimortem trophy‐taking behaviour, cases of scalping survival are occasionally reported in the historical documents of the American Colonial Period and the 19^th century westward expansion. Survival cases are also detected in pre‐Columbian bioarchaeological contexts. Although scalp avulsion injuries can heal without complication, often the process is compromised by secondary osteomyelitis, usually attributable to environmentally ever‐present Staphylococcal or Streptococcal bacteria. A scalping survivor case from the late prehistoric (AD 1200–1600) Hampton site (40RH41) of East Tennessee unusually displays infectious sequelae in the area denuded by scalp avulsion which are pathognomonic for treponemal disease (caries sicca, stellate scarring). This infection is probably a reflection of the easy opportunity afforded by the large size of the wound bed, poor post‐trauma hygiene, and direct inoculation of the diploë by a ubiquitous Treponema.

Reduced Population Variance in Strontium Isotope Ratios Informs Domesticated Turkey Use at Chaco Canyon,New Mexico,USA

Traditionally, strontium isotopes (⁸⁷Sr/⁸⁶Sr) have been used as a sourcing tool in numerous archaeological artifact classes. The research presented here demonstrates that ⁸⁷Sr/⁸⁶Sr_bioapatite ratios also can be used at a population level to investigate the presence of domesticated animals and methods of management. The proposed methodology combines ecology, isotope geochemistry, and behavioral ecology to assess the presence and nature of turkey (Meleagris gallopavo) domestication. This case study utilizes ⁸⁷Sr/⁸⁶Sr_bioapatite ratios from teeth and bones of archaeological turkey, deer (Odocoileus sp.), lagomorph (Lepus sp. and Sylvilagus sp.), and prairie dog (Cynomys sp.) from Chaco Canyon, NM, USA (ca. A.D. 800–1250). Wild deer and turkey from the southwestern USA have much larger home ranges and dispersal behaviors (measured in kilometers) when compared to lagomorphs and prairie dogs (measured in meters). Hunted deer and wild turkey from archaeological contexts at Chaco Canyon are expected to have a higher variance in their ⁸⁷Sr/⁸⁶Sr_bioapatite ratios, when compared to small range taxa (lagomorphs and prairie dogs). Contrary to this expectation, ⁸⁷Sr/⁸⁶Sr_bioapatite values of turkey bones from Chacoan assemblages have a much lower variance than deer and are similar to that of smaller mammals. The sampled turkey values show variability most similar to lagomorphs and prairie dogs, suggesting the turkeys from Chaco Canyon were consuming a uniform diet and/or were constrained within a limited home range, indicating at least proto-domestication. The population approach has wide applicability for evaluating the presence and nature of domestication when combined with paleoecology and behavioral ecology in a variety of animals and environments.     

Stable Isotopes,Chronology, and Bayesian Models for the Viking Archaeology of North-East Iceland

This paper reviews the results of a long-term research project that used stable isotope analyses (δ¹³C, δ¹⁵N, δ³⁴S) and Bayesian mixing models to better model the chronology for a presumed Viking Age cemetery at Hofstaðir, near Lake Mývatn in north-east Iceland. δ¹³C and radiocarbon dating indicated that many of the individuals consumed a large amount of marine protein, which results in a marine reservoir effect (MRE), making ages older than expected. In addition to the MRE, geological activity in the region has the potential to introduce massive quantities of radioactive ‘dead’ carbon into the freshwater system, resulting in a very large freshwater reservoir effect (FRE) that can offset radiocarbon ages on the order of a few thousand years. The radiocarbon dates of organisms that derive an unknown proportion of their carbon from both marine and freshwater reservoirs are extremely difficult to ‘correct’, or, more appropriately, model. The research not only highlights the complexities of dealing with multiple reservoirs, but also how important it is to develop models that are temporally and geographically relevant to the site under study. Finally, it shows how this data can be used to inform the development of chronological models for refining the dating for archaeological activity.     

Mormon History,Text, Colour,and Rites

Mormonism's growth from its 1830 inception to its 2005 near twelve million world membership, has not only initiated a debate over whether, perhaps, it is likely to become the next world‐religion after Islam, ¹ 1 Stark, Rodney , “The Rise of a New World Faith,” Review of Religious Research 26 (1984 ): 18 – 27 .
but has, in recent decades, also witnessed the publication of numerous books that help foster an interest in what is already becoming a distinctive field of study. Though none of the four books reviewed here constitutes an introductory overview, ² 2 For which see, Thomas O'Dea, The Mormons (Chicago: University of Chicago Press, 1957); Jan Shipps, The Story of a New Religious Tradition (Urbana and Chicago: University of Illinois Press, 1985); Douglas J. Davies, Introduction to Mormonism (Cambridge: Cambridge University Press, 2003).
each introduces a set of major issues within contemporary Mormon studies and engages, respectively, with faith‐related attitudes to historical material, the Book of Mormon, the changing status of black males in the church, and Freemasonry's impact on Mormonism's origin.     

Mummies, maize, and manure: multi-tissue stable isotope analysis of late prehistoric human remains from the Ayacucho Valley, Perú

This paper reports the δ¹³C and δ¹⁵N values of bone collagen, muscle and skin from several late prehistoric–early colonial (AD 1490–1640) mummies from Perú's Ayacucho Valley. The mean of the δ¹³C and δ¹⁵N values of bone collagen are −11.5 ± 1.4 and 11.1 ± 0.7‰, respectively. The mean of the δ¹³C values for Vinchos skin is −11.8 ± 1.2‰ and the mean of δ¹⁵N values is 13.2 ± 0.5‰. The samples of muscle tissue have a δ¹³C mean of −11.9 ± 0.9‰ and a δ¹⁵N mean of 12.7 ± 0.3‰. The data from bone collagen indicate maize was the basis of the region's subsistence economy. A significant correlation between δ¹³C and δ¹⁵N values of bone collagen (R² = 0.75) is consistent with the preferential fertilization of maize with composted manure. Both skin and muscle samples are consistently enriched in δ¹⁵N relative to paired samples of bone (2.1 ± 0.5 and 1.6 ± 0.7‰, respectively), possibly as a result of short term physiological stress or differential decomposition.     

High-resolution radiocarbon dating of marine materials in archaeological contexts: radiocarbon marine reservoir variability between Anadara, Gafrarium, Batissa, Polymesoda spp. and Echinoidea at Caution Bay, Southern Coastal Papua New Guinea

The remains of shellfish dominate many coastal archaeological sites in the Pacific and provide a wealth of information about economy, culture, environment and climate. Shells are therefore the logical sample type to develop local and regional radiocarbon chronologies. The calibration of radiocarbon (¹⁴C) dates on marine animals is not straightforward, however, requiring an understanding of habitat and dietary preferences as well as detailed knowledge of local ocean conditions. The most complex situations occur where terrestrial influences impinge on the marine environment resulting in both the enrichment and depletion of ¹⁴C (Ulm Geoarchaeology 17(4):319–348, 2002; Petchey and Clark Quat Geochronol 6:539–549, 2011). A sampling protocol that combines a high-resolution excavation methodology, selection of short-lived samples identified to species level, and a tri-isotope approach using ¹⁴C, δ¹³C and δ¹⁸O, has given us the ability to identify ¹⁴C source variation that would otherwise have been obscured. Here, we present new research that details high-resolution mapping of marine ¹⁴C reservoir variation between Gafrarium tumidum, Gafrarium pectinatum, Anadara granosa, Anadara antiquata, Batissa violacea, Polymesoda erosa and Echinoidea from the Bogi 1 archaeological site, Caution Bay, southern coastal Papua New Guinea. These isotopes highlight specific dietary, habitat and behavioural variations that are key to obtaining chronological information from shell radiocarbon determinations.     

Paleoenvironment of Australopithecus anamensis at Allia Bay,East Turkana,Kenya: evidence from mammalian herbivore enamel stable isotopes

Carbon (¹³C:¹²C) and oxygen (¹⁸O:¹⁶O) stable isotope ratio analysis was performed on well-preserved tooth enamel carbonate from fossil fauna recovered from a single excavation at the early hominid site of Allia Bay, East Turkana, Kenya. These data show greater enrichment in both ¹²C and in ¹⁶O than expected, based on the oxygen isotope composition of the middle Pliocene ocean, and on today’s ecology. The pattern of these data argues against a diagenetic explanation for the enrichment. The carbon stable isotope data of known browsers suggest a more extensive canopy cover during the middle Pliocene than today’s environments. The presence of browsing pig genera, hippo genera, deinotheres, and giraffes with δ¹³C values more negative than today’s all argue for woodland habitats. The presence of several grazing genera point to the presence of grasslands as well. The oxygen stable isotope ratios indicate that the site was better-watered than today, although the source, seasonal pattern, and actual amount of water cannot be determined from these data. The overall mosaic of environments suggested by these data, in combination with reports of exotic trees recovered in nearby deposits, indicate that woodlands were present in the region 3.9 my, unlike today. Such a setting matches expectations for the selective advantages of nut-eating, bipedal hominids over other hominoids.     

Radiocarbon Marine Reservoir Effect in Human Remains from the Kitakogane Site,Hokkaido, Japan

Accelerator mass spectrometry (AMS) was used to measure radiocarbon (¹⁴C) in bones excavated from the Late Jomon shell midden at the Kitakogane site, Hokkaido, Japan. Comparison between ¹⁴C ages of terrestrial and marine mammals from the same site showed systematic age differences which could be attributed to the ¹⁴C marine reservoir effect in the western North Pacific Ocean. Furthermore, this effect was clearly observed in human remains from this site, indicating a heavy dependence on seafood. Dietary habit was estimated from δ¹³C and δ¹⁵N measured in the same human remains. Apparent ¹⁴C ages indicated 79% of protein originated from marine sources.     

Comments on Graf, Journal of Archaeological Science 36, 2009 “ “The Good, the Bad, and the Ugly”: evaluating the radiocarbon chronology of the middle and late Upper Paleolithic in the Enisei River valley, south-central Siberia”

Here I present a critical evaluation of the analysis conducted by Graf [Graf, K.E., 2009. “The Good, the Bad, and the Ugly”: Evaluating the radiocarbon chronology of the middle and late Upper Paleolithic in the Enisei River valley, south-central Siberia. Journal of Archaeological Science 36, 694–707] of the Paleolithic radiocarbon (¹⁴C) dataset for the Upper Paleolithic sites in the Yenisei River basin of Central Siberia. Graf applied a rating system to the corpus of existing ¹⁴C data for the region, and announced some new ¹⁴C dates. The results obtained, however, are highly biased due to several factors, including prejudice concerning the higher accuracy of the AMS technique in ¹⁴C dating and that ¹⁴C dates from the same cultural component should overlap with plus–minus two sigmas; ambiguities with the subdivision of the Lateglacial period; artificially high sample selection criteria; incomplete factual material; and unjustifiable and misleading statements on the ¹⁴C dating of fossil bones and the issue of Last Glacial Maximum human presence in Siberia. As a result, the conclusions made by Graf [Graf, K.E., 2009. “The Good, the Bad, and the Ugly”: Evaluating the radiocarbon chronology of the middle and late Upper Paleolithic in the Enisei River valley, south-central Siberia. Journal of Archaeological Science 36, 694–707] are unconvincing. New analysis is necessary in order to improve the quality of treatment of the original data for the Upper Paleolithic ¹⁴C chronology in the Yenisei River basin.     

Stable isotope analysis of human and animal remains from the Late Upper Palaeolithic site of Balma Guilanyà, southeastern Pre-Pyrenees,Spain

Stable isotope analysis of carbon (¹³C/¹²C) and nitrogen (¹⁵N/¹⁴N) was performed on collagen extracted from three human and five herbivore bone and tooth samples from the Late Upper Palaeolithic site of Balma Guilanyà (Catalonian Pre-Pyrenees, Spain). Contextual and palaeoecological data as well as radiocarbon dates indicate that the studied occupation phase took placed during the Bolling/Allerod interstadial (GI-1a event). The human remains were co-mingled without any anatomical association, corresponding to a minimum number of three individuals, and it was not possible to determine if the three analyzed samples are from one or more individuals. The mean isotope values obtained from the human remains are δ¹³C = −19.8‰ and δ¹⁵N = 6.7‰, while those of the large herbivores (red deer and wild goat) were −19.8‰ and 1.7‰ for δ¹³C and δ¹⁵N respectively. This indicates that the main source of protein in the diet of the Balma Guilanyà human(s) came from terrestrial herbivores. There is no zooarchaeological or isotopic evidence for the consumption of freshwater or marine resources at the site, which lies 80 km from the present Mediterranean coast. The low δ¹⁵N values observed in both human and animal samples correspond to a trend reported by other researchers working in northwestern Europe: a significant δ¹⁵N reduction in collagen from bones datable within 20,000–10,000 BP, followed by a rise to present values in the Early Holocene. This phenomenon, generally attributed to climatic and/or pedological processes, had not been previously observed in the Mediterranean region and, until now, was thought to be restricted to northern Europe.     

Memories of an Imperial City: Race,Gender, and Birmingham,Alabama

September 15, 2013, marked the 50^th anniversary of the 16^th Street Baptist Church bombing in Birmingham, Alabama, USA. The bombing remains one of the most infamous events in the history of white supremacist violence in the United States. While conventional accounts of the event and its aftermath often consider the legal restructuring of the US state following the passage of subsequent Civil Rights legislation, little has been written about the transnational significance of Birmingham in shaping the character of US power abroad. This article argues that memorialisation and cultural architecture of Birmingham represent a significant crucible forging a particular style of liberal empire. Tracing a cultural genealogy of Birmingham through the writings of former Secretary of State and National Security Advisor Condoleezza Rice and famed scholar-activist Angela Davis, I demonstrate how Birmingham, as a site of historic black struggle, has been remembered alongside the place-making of empire.     

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.
