Investigating the use of land during the medieval period at the celebrated ceremonial area of Angkor, the authors took a soil column over 2.5m deep from the inner moat of the Bakong temple. The dated pollen sequence showed that the temple moat was dug in the eighth century AD and that the agriculture of the immediate area subsequently flourished. In the tenth century AD agriculture declined and the moat became choked with water-plants. It was at this time, according to historical documents, that a new centre at Phnom Bakeng was founded by Yasovarman I.

Why were infants buried beneath house-floors at the Mesolithic and early Neolithic site of Lepenski Vir? Undertaking a new analysis of the neonate remains at Vlasac and Lepenski Vir the authors reject the idea of sacrificial infanticide, and demonstrate a consistency of respect in these burials. They suggest that the deaths were mourned and the dead, like the living, were given protection by the houses they were buried in. The treatment of mothers and children suggests increasing social cohesion from the Mesolithic at Vlasac to the early Neolithic at Lepenski Vir.

Various methods of analysing the dating of the late Glacial suggest various interpretations. Here, in answer to a paper from 1997, radiocarbon dates are calibrated and used to reconsider the dating of this contentious period.

What happened at the sites of prehistoric burial mounds after they were erected? In the southern highlands of Brazil and Argentina the pre-Hispanic mounds of the twelfth-thirteenth centuries AD are surrounded by large circular enclosures with avenues leading to their centre. The authors discovered that the banks of the surrounding enclosure were built up over several generations of time, accompanied by a succession of ovens. Ethnohistoric observations of more recent peoples in the same region suggested an explanation: the cremation of a chief was followed by periodic feasts at his mound, where meat was steamed and maize beer prepared at the edge of the gathering.

A new study of Kamares ware, integrating stylistic and petrographic analysis, suggests that Protopalatial Knossos was a centre of ritual consumption rather than production, obtaining some of its specialized vessels for drinking and feasting ceremonies from production centres elsewhere in central Crete.

What do we know about the effects of the transition to agriculture on human biology? A literature has grown up that gives us the impression that we know a great deal about what happened to bones and teeth when people became sedentary farmers. A review of the sources of these ideas and the evidence supporting them, especially based on work in Portugal, reveals that a reconsideration of the biological consequences of farming in Europe is overdue.

Amongst the numerous images found on the walls of Palaeolithic caves, fluted lines, made by fingers dragged through a skin of wet clay remain some of the most intriguing. In their study of images at Rouffignac, the authors undertook experiments with a range of modern subjects who replicated the flutings with their hands. Comparing the dimensions of the experimental flutings with the originals, they conclude that the patterns on the roof of Chamber A1 at Rouffignac were made by the fingers of children aged between 2 and 5 years old. Given the current height of the chamber, such children would have needed to be hoisted aloft by adults. Who knows what lessons in art or ritual were thereby imparted to the young persons…

Zvelebil here rejoins to Ammerman's criticisms, published in the March issue, of his earlier paper on Indo-European languages and the dispersal of agriculture into Europe, and takes the opportunity to make a broader statement about the character of Neolithic settlement on the full continental scale.

An opportunity to investigate in advance of new construction led to the discovery of five Mesolithic hazel fish traps some 6.3m below mean sea level in the River Liffey. Closely paralleled on the continent of Europe they imply a well organised community that knew how to catch fish using the tide, to make wattle-work and baskets and who undertook coppicing on an eight year cycle in about 6100-5700 cal BC. The likelihood of more Mesolithic remains under European towns that have remained attractive to fishers and settlers has considerable implications for Cultural Resource Management. Do we always know how to find and access such delicate and important traces?

The Shuidonggou site cluster in northern China contains 12 different early prehistoric sequences with great potential to cast light on the transition to Upper Palaeolithic behaviour in East Asia. Here researchers present the latest results from Locality 2, reporting seven occupation levels with hearths, animal bone and diverse industries. Although previously compared with European Upper Palaeolithic sequences, the new work proposes a different trajectory of development. Distinctive macroblade technology arrived in the area, possibly from Mongolia or Siberia, about 41000–34000 years ago. This industry subsequently disappeared, to be replaced by flake technologies.

What conditions preserve archaeology, and what conditions accelerate decay? Here experts from York, using the wealth of experience and data gathered from that city, discuss the issues.

China is one of the places for the origin of the Asian cultivated rice (Oka 1988), but there are different theories for precise locations where ancient cultivated rice first originated, including those proposing South China and Yunnan (Li 1989) or the middle and lower Yangtze River Valley (Yan 1989), or the middle Yangtze and the upper Huai River Valley (Wang 1996) as the site of the oldest rice cultivation in China. The discovery (Zhang et al. 1994) of ancient rice at Jiahu in Henan province not only pushed the history of rice agriculture in the Huai River region back to 9000 BP, but also indicated the existence of an agricultural tradition of rice cultivation in the region from the beginning of the Holocene Anathermal until the end of the Holocene megathermal.

The central portion of the California ‘culture area’ is a microcosm of the larger California province, which is a patchwork of landforms, microclimates and hydraulic régimes. There are large coastal bays, rugged scrubby foothills, broad intermontane valleys with massive river systems and extensive deltaic wetlands (FIGURE 1).

The symbolism of the horse in Eneolithic society is explored in this paper. Recent excavations in the Eurasian steppes demonstrate the importance of horses before domestication and horse riding became common; showing they were eaten, exploited and revered.
