The chronology of the Neolithic and Bronze Age cultures in Gansu and Qinghai provinces, northwest China, is mainly based on conventional radiocarbon dates from unidentified charcoal, which may be inaccurate in view of the possible “old wood” problem of 14C dating. To discuss the reliability of the chronology of those prehistoric cultures, accelerator mass spectrometry (AMS) dates of short-lived charred seeds were compared to conventional 14C dates of unidentified charcoal from the same flotation samples in 15 Late Neolithic and Bronze Age sites in the area. The results show that 14C dates of unidentified charcoal are obviously older than those of charred seeds in 5 of the 15 flotation samples. This work suggests that the old-wood problem of 14C dating might be related to human subsistence strategies and local vegetation variation during different prehistoric cultural periods in Gansu and Qinghai provinces, which should be discussed before establishing the chronology of Neolithic and Bronze Age cultures in the area.

Transcontinental exchange emerged and intensified in northern China since the late fifth millennium BP (Before present), especially in the arc, which was the core area of the eastern part of the trans-Eurasian exchange during the Late Neolithic and the Bronze Age. In the arc, the exchange profoundly affected the human subsistence strategy and human-environment relationship. Relative to the crop patterns and human diets during the Bronze Age in northern China, systematic investigations of zooarcheological data based on broad spatial and temporal framework to understand the influence of introduced livestock and indigenous livestock on human subsistence are lacking. To show the spatial-temporal variation in animal utilization patterns and its relation to prehistoric trans-Eurasian exchange, the zooarcheological data from 40 sites in northern China dated between 5000 and 2500 BP were analyzed. The strategy of animal utilization in northern China changed substantially from 5000 to 2500 BP, with notable spatial features in different chronological phases. From 5000 to 4300 BP, wild mammals and indigenous livestock (pig, dog) use dominated in the arc and the North China Plain (NCP). During 4300–3500 BP, the importance of introduced livestock (cattle, sheep/goat, horse) exceeded that of indigenous livestock in the arc, whereas indigenous livestock continued to dominate in the NCP. Indigenous livestock acted as the most important animal subsistence in northern China, although the exploitation of introduced livestock increased during 3500–2000 BP. These spatio-temporal differences in animal utilization appear to be closely associated with the prehistoric trans-Eurasian exchange, but were also affected by local environment, agriculture development, and climate change.

This article reports on 10 new accelerator mass spectrometry (AMS) radiocarbon dates from early phases of the Early Bronze Age at the long-lived settlement of Pella (modern Tabaqat Fahl) in the north Jordan Valley. The new AMS dates fall between 3400 and 2800 cal BC, and support a recent suggestion that all Chalcolithic period occupation had ceased by 3800/3700 cal BC at the latest (Bourke et al. 2004b). Other recently published Early Bronze Age14C data strongly supports this revisionist scenario, suggesting that the earliest phase of the Early Bronze Age (EBA I) occupied much of the 4th millennium cal BC (3800/3700 to 3100/3000 cal BC). As this EB I period in the Jordan Valley is generally viewed as the key precursor phase in the development of urbanism (Joffe 1993), this revisionist chronology has potentially radical significance for understanding both the nature and speed of the move from village settlement towards a complex urban lifeway.

Lime burials are a characteristic phenomenon of the protohistoric funerary tradition on the Balearic Islands. At Cova de Na Dent, six samples, representing the entire stratigraphy of the lime burial, were taken for analysis. The radiocarbon dates suggested that the lowest levels of the burial were Late Bronze Age. This is in contradiction with the general belief that the lime burials are a late Iron Age phenomenon. Therefore, a new analysis strategy is put forward, focusing on the so-called 1st fraction, the first CO2released during the acid lime reaction, which is supposed to be free of fossil carbon. The analysis demonstrates the impossibility to eliminate the fossil carbon fraction completely. This is probably due to the different geological formation of the local limestone deposits (ancient reef barriers) compared to the previous lime burials of Mallorca all coming from mountain areas.14C analysis from a cremation layer without lime at the onset of the lime burial reveals an Iron Age origin of the Cova de Na Dent lime burial.

Prehistoric remains were recorded by CFA Archaeology Ltd (CFA) in 2002-03 during a programme of fieldwork at the landfill site within the boundaries of Stoneyhill Farm, which lies 7km to the southwest of Peterhead in Aberdeenshire. These included a clearance cairn with a Late Bronze Age lithic assemblage and a burial cairn, with Late Neolithic and Early Bronze Age lithics and Beaker ceramics. Other lithic scatters of similar date had no certain associations, although pits containing near-contemporary Impressed Wares were nearby. Additional lithic assemblages included material dated to the Mesolithic and Early Neolithic. What may be proto-Unstan Wares in an isolated pit were associated with radiocarbon dates (barley) of the first half of the fourth millennium bc. These findings represent a substantial addition to the local area's archaeological record and form an important contribution to the understanding of lithic technology and ceramics in earlier prehistoric Scotland.This paper is dedicated to the memory of Ian Shepherd, whose site visits enlightened this and other projects undertaken by one of the authors (IS).

The analysis of pottery materials of Posolskaya site (excavations by E. A. Khamzina in 1959), which is located on the southeast coast of Lake Baikal (Kabansk district, the Republic of Buryatia), is carried out in this article. Based on morphological features, several groups of pottery with a set of characteristic features are identified. A comparison of them with the materials of supporting multilayer objects on the coast of Baikal and Cis-Baikal area, in general, made it possible to determine the relative and absolute chronology of these groups. It was determined that pottery complexes of layers 2 and 3 contain artifacts of different cultural and chronological periods from the Neolithic to the Bronze Age in a mixed state. They contain materials of the Middle and Late Neolithic (Posolskaya and Ust-Belaya ceramic types), the Early Bronze Age (pottery with pearls, with fingernails and Northern Baikal type) and the Late Bronze Age (Tyshkine-Senogdinsk type). Reticulated pottery, recorded in small quantities, was found in all complexes of the Neolithic era of the region. The pottery studies showed, on the one hand, its morpho-typological proximity with similar pottery in the south of Central Siberia as a whole. On the other hand, there were some regional differences (thickening of the corolla in bulk on Posolskaya type pottery in two versions: from the outside and from the inside; a variety of compositional structures on vessels with an external thickening of the corolla was revealed, expressed in simplification of the ornamental design; pottery combining features of Posolskaya and Ust-Belaya types was distinguished. A series of radiocarbon dates from stratified complexes of multilayer objects on the Baikal coast made it possible to determine chronological ranges for almost all pottery groups identified at Posolskaya site. Posolskaya type pottery in two of its variants corresponds to a chronological interval of 6750–6310 cal BP; Ust’-Belaia type (focusing on the dates of Ulan-Khada and the Gorelyi Les) – 5581–4420 cal BP; pottery with pearls and constructions from wide lines of the retreating spatula – 4500–3080 cal BP, pottery with finger pinches corresponds to 3370–3230 cal BP; Northern Baikal type – 3346–3077 cal BP; Tyshkine-Senogdinsk type – 2778–1998 cal BP.

AbstractThe Xindian culture of northwest China has been seen as a prototypical example of a transition toward pastoralism, resulting in part from environmental changes that started around 4000 years ago. To date, there has been little available residential data to document how and whether subsistence strategies and community organization in northwest China changed following or in association with documented environmental changes. The Tao River Archaeology Project is a collaborative effort aimed at gathering robust archaeological information to solidify our baseline understanding of economic, technological, and social practices in the third through early first millennia BC. Here we present data from two Xindian culture residential sites, and propose that rather than a total transition to nomadic pastoralism—as it is often reconstructed—the Xindian culture reflects a prolonged period of complex transition in cultural traditions and subsistence practices. In fact, communities maintained elements of earlier cultivation and animal-foddering systems, selectively incorporating new plants and animals into their repertoire. These locally-specific strategies were employed to negotiate ever-changing environmental and social conditions in the region of developing ‘proto-Silk Road’ interregional interactions.

To formulate a solid chronology of the northwest Belgian Bronze Age barrow phenomenon, a critical review of the available radiocarbon dates was necessary. The resulting14C chronology of the barrows was compared with the14C chronologies of the Late Neolithic Bell Beaker graves, the Bronze Age metalwork depositions, the evidence of barrow reuse, and the Bronze Age longhouses. This research revealed interesting patterns concerning the appearance and disappearance of the barrow phenomenon. The earliest14C-dated barrows are dated during the Late Neolithic and coincide with the presence of the Bell Beaker culture in the region. The peak of the barrow-building practice occurred between 1700 and 1500/1400 cal BC, a period of flourishing trade networks in the regions along the North Sea basin. The period around 1500 cal BC is characterized by the disappearance of barrow-building practices and the sudden appearance of ritual depositional practices, reflecting changes in society.

The site of Kouphovouno, just south of Sparta, is one of the main Neolithic sites in Laconia. It was first settled in the Middle Neolithic period and developed into a large village with remains occupying some 4–5 hectares. A joint team from the British School at Athens and the Ecole française d'Athènes carried out excavations at the site in 2001–6. There is evidence for occupation during the Bronze Age, and for an extensive Late Roman villa, but this article concentrates on the chronology of the site during the Middle and Late Neolithic phases. The evidence from stratigraphic sequences, pottery typology, seriation and Bayesian analysis of the radiocarbon dates is brought together to present a detailed chronological sequence covering the periodc.5800–5000bc. In particular the analysis relies on the results from two deep soundings, one excavated in Area C carried down to the natural sediments underlying the site and exposing the earliest period of occupation, and the second in Area G covering the later Middle Neolithic and much of the Late Neolithic phase. The findings from Kouphovouno are placed more generally in the context of finds from other sites in the Peloponnese and in particular in relation to the important sequence from Franchthi Cave. On the basis of the evidence it is argued that the transition from Middle Neolithic to Late Neolithic in southern Greece was not abrupt, as had previously been thought, but showed a gradual evolution. This finding has implications for our understanding of the process of transformation that southern Greece underwent in the course of the later sixth millenniumbc.
