Stable isotope dietary analysis of prehistoric populations from the Minusinsk Basin,Southern Siberia,Russia: a new chronological framework for the introduction of millet to the eastern Eurasian steppe

We report the results of stable carbon and nitrogen isotope analysis of 354 human and faunal samples from five archaeological cultures of the Minusinsk Basin, Southern Siberia – Afanasyevo, Okunevo, Andronovo, Karasuk and Tagar (ca. 2700–1 BC) – a key location in Eurasia due to its position on a northern corridor linking China and central Eurasia. The results indicate that the diet of Eneolithic to Middle Bronze Age (Afanasyevo to Andronovo) populations was primarily C₃-based, with C₄ plants only becoming an important component of the diet in the Late Bronze Age Karasuk and Early Iron Age Tagar cultures. Freshwater fish seems to have been an important constituent of the diets in all groups. The findings constitute the earliest concrete evidence for the substantial use of millet in the eastern Eurasian steppe. We propose that it was probably introduced from Northwestern China during the Karasuk culture at the start of the Late Bronze Age, ca. 1500 BC. We conclude with a discussion of the implications for the nature of pastoralist economies on the steppes.     

Pre‐Modern Boathouses: a maritime perspective from northern Norway

Most Scandinavian boathouses predating the Reformation (AD 1537) are located in Norway, starting in the Early Iron Age, and a majority are found in the north. Following a critical review of Norwegian boathouse studies from a historical and regional perspective, current research themes in northern Norway are discussed. Boathouses are viewed as multifunctional entities providing insights into the marine economy, social organization, and ethnic interaction between Sami and Norse populations. A more balanced and holistic perspective is needed in which boathouses are seen as a central component of the maritime cultural landscape with uses extending substantially beyond boat storage. © 2012 The Authors     

“华光礁一号”南宋沉船船板中硫铁化合物分析

鉴于硫铁化合物对海洋出水木质文物的特殊危害,通过 X射线衍射(XRD)、等离子体发射光谱(ICP-AES)和 X射线光电子能谱(XPS)等分析手段,对“华光礁一号”南宋沉船船板残块中的硫铁化合物进行了分析研究。结果表明,所采集的样品中含有大量的 Fe和 S元素,并且其分布深度至少可达 4cm。两种元素的化学状态基本可分为铁的氧化物、硫铁化合物、硫酸盐和其它还原性硫四大类。其中,硫铁化合物主要以 FeS和 FeS₂形式存在,并已部分氧化成硫酸盐。因此,在后续的保护处理过程需着重对其酸化过程进行控制,以有利于文物的长期保存。     

Initial results from the programme of petrographic analysis of Iron Age pottery from the United Arab Emirates

This article presents the results of petrographic analyses of a collection of sixty potsherds from various sites of the Iron Age period in south‐eastern Arabia. Several macroscopic groups were identified during previous research. The fine red painted ware and the sandy buff ware appear to be homogeneous in composition and might represent two groups of production. Compositionally, fine red painted ware recalls Bronze Age pottery groups in Oman. Sandy buff ware could have been produced in the oasis of Al Ain, in the Emirate of Abu Dhabi. Both groups are represented at several sites, which indicates regional exchange. One sherd from Rumeilah could be related to Mesopotamian ceramics and is probably a Mesopotamian import.     

A regional investigation of subadult dietary patterns and health in late Iron Age and Roman Dorset,England

This is the first regional analysis of the impact of Romanisation on subadult dietary patterns and related health parameters in Britain. A sample of 200 subadults from late Iron Age (LIA) and Romano-British (RB) Dorset were examined for dental health and specific metabolic diseases, and a sub-sample of 29 individuals were selected for nitrogen and carbon isotope analysis. The results showed that dental health declined in the Romano-British period and the incidence of scurvy and rickets rose. Increased consumption of marine foods in the RB period is indicated by an increase in δ¹³C between the LIA and RB subadults. After early childhood, there was no age-dependent variation in dietary protein in the RB and LIA populations from Dorset. We propose that these changes related to the introduction of urban living, Romanised diets and population migration.     

The provenancing of ochres from the Neolithic Temple Period in Malta

Ochres have played an important role in early human societies, and recent studies have shown that these pigments are important tools in establishing trade routes between countries as particular varieties of the material were sought for use by these ancient groups. This paper explores the provenancing of the ancient ochres used during the Neolithic Temple Period on the Maltese islands. Here ICP-AES was employed to establish geochemical trends and ‘signature’ elements present in ochre that had previously been thought to have been imported from mainland Europe. When coupled with statistical tests, data was used to link the archaeological pigments to a geological source. Results revealed a strong link between the Maltese archaeological pigments and local sources, which had never been studied prior to this project. These indicated that, contrary to popular belief, the Maltese archipelago was the most likely source for Neolithic ochre.     

Stable isotope investigations of charred barley (Hordeum vulgare) and wheat (Triticum spelta) grains from Danebury Hillfort: implications for palaeodietary reconstructions

Palaeodietary studies typically focus on the analysis of bone collagen due to the limited availability of plant remains. Isotopic analysis of plant remains, however, allow for a more extensive consideration of the contribution of plants to the human diet and can potentially provide information about the environment in which the crops were grown. This paper reports the results of carbon and nitrogen isotope analyses performed on charred barley and wheat grains recovered from pits within Danebury Iron Age hillfort. To the best of our knowledge, this is the first Iron Age site in Britain from which charred grains have been isotopically analysed. Our results suggest that cereals found at the hillfort were grown in several different environmental contexts. The isotope data demonstrate that the herbivores were not consuming a diet primarily based on grains as the δ¹⁵N values of the grains are very similar to those of the herbivores. Palaeodietary investigations typically assume that humans eating plant protein only would have the same δ¹⁵N value as the local herbivores. This assumption is clearly invalid at Danebury, where the humans and animals appear to have consumed either different parts of the same plants or different plants. Researchers typically interpret high differences between human and animal δ¹⁵N values as indicative of diets high in animal protein, however where major plant resources have δ¹⁵N values similar to those of the herbivores our ability to distinguish between plant and animal sources of protein in the diet is limited. Our research has demonstrated that whenever possible it is desirable to measure the isotopic signatures of potential major plant resources in order to understand past subsistence strategies.     

Fuelwood,crops and acorns from Iritegi cave (Oñati,Basque Country)

Abstract

We present the analyses of plant macroremains from Iritegi, a cave from Northern Iberia with archaeological levels dated from the Chalcolithic to the Iron Age. Wood charcoal assemblages are dominated throughout the sequence by Fraxinus. Other important taxa are Quercus subg. Quercus, followed by Corylus avellana, Fagus sylvatica, Ilex aquifolium, Taxus baccata and Ulmus. Acer, Alnus and Maloideae occur in very low numbers. The high percentages of Fraxinus are possibly result from the selection of ash for fodder. Evidence for the use of crops (Hordeum vulgare, Triticum aestivum/durum) comes only from the Chalcolithic contexts. The identification of acorns in one Chalcolithic hearth shows that roasting of these nuts was taking place maybe to improve taste and to facilitate further processing or to improve storage conditions. The results show that plant food gathering still played a role within the subsistence of farming human groups in the region.     

Cultural Modification of the Dentition in Prehistoric Cambodia

Intentional dental modification, in the form of ablation and filing, is reported for the first time from Cambodia in two late prehistoric sites (Phum Snay and Phum Sophy, c. 2500 to 1500 bp ). Bioarchaeological research is relatively new for this region, and this study significantly adds to our reconstruction of past behaviours in mainland Southeast Asia. The skeletal samples combine both excavated material and large looted collections in the form of ossuaries. People from Phum Sophy and Phum Snay had similar rates of anterior maxillary dental ablation, 60 and 47%, respectively, and 21.4 and 7.7%, respectively, in the mandible. Patterns of ablation most commonly involve the removal of the maxillary lateral incisors. Intentional filing was less common than ablation but affected Phum Snay and Phum Sophy individuals to a similar level (4–7%). Filing was also restricted to the anterior dentition, and a range of patterns were evident, many involving filing of the mesial and distal aspects of the crown of the upper and lower incisors and canines to give a pointed appearance. Patterns of ablation or filing were not strongly associated with a particular sex or age group. However, a limited number of ablation and filing patterns were exclusive to each site. The significance of this practice in relation to rites of passage, status, community and family relationships, and trauma is discussed. It is also shown that the modifications show distinct differences in prevalence and pattern, particularly that of filing, to nearby temporal neighbours in southern Cambodia and northeast Thailand, suggesting a unique cultural behaviour for this region.
