North-east China occupies an important geographic position for understanding the process of Neolithisation in East Asia. Although archaeologists have long debated the trajectory of change in this region, a lack of intensive survey and excavation has precluded convincing interpretations. This article presents research on the newly excavated sites of Huayang and Taoshan in the southern Lesser Khingan Mountains, with a particular focus on the lithic assemblages. Comparative and environmental analyses demonstrate the largely uniform trajectory of lithic technologies across north-east China and close correspondence with Late Glacial palaeoclimatic and palaeoenvironmental changes.

The effects of the 4.2 kya climatic event on northern Mesopotamia have been the subject of significant scholarly debate, with the notion of a megadrought that forced local populations to migrate attracting particular attention. Here, the authors analyse stable carbon (δ13C) and nitrogen (δ15N) isotopes in human tooth and bone samples to assess trends in subsistence practice at three sites in Syria before, during and after the presumed megadrought event. Despite the proximity of the sites, isotopic differences between them are more significant than diachronic change. Combined with other archaeological evidence, these results indicate a continuity in subsistence patterns, with no indication of disruption associated with the 4.2 kya event.

The date and significance of the megalithic jar sites of central Laos are comparatively poorly understood features of the Southeast Asian archaeological landscape. First explored systematically in the 1930s, only limited research on these sites has been undertaken since. This article presents the recent excavations at Ban Ang—or site 1—a megalithic jar site of nearly 400 jars, located in Xieng Khouang Province. The results confirm the findings of earlier research, but additionally reveal a range of mortuary practices, high rates of infant and child mortality, and new evidence dating these interments to the ninth to thirteenth centuries AD.

The impact of Amazonia on the history and development of late prehistoric (c. AD 500–1500) Andean highland polities has been largely ignored. This article considers how shifting exchange relations between Amazonia and the Andes may have greatly influenced state-formation processes. It is argued that Arawak expansion in the Amazonian lowlands, completed by c. AD 500, was a prerequisite development for stimulating the rise of Andean highland empires, which were heavily dependent upon imported prestige Amazonian feathers. Future research directions are suggested in order to enhance our understanding of late prehistoric state formation in the Americas.

El Médano-style rock art from the Atacama Desert coast in Chile provides one of the most spectacular and expressive representations of ancient marine hunting and maritime traditions. These red pictographs comprise hundreds of hunting scenes and portray a complex marine hunter-gatherer society. This study presents the discovery of El Médano pictographs from new sites—in particular the Izcuña ravine—and seeks to understand further the processes of marine hunting and the interspecies relationships between hunter and prey. When combined with archaeological evidence, this analysis provides important new information concerning the value and significance of this rock art to those ancient hunter-gatherers.

Since the seminal research by Caton-Thompson and Gardner over 80 years ago, the archaeology of the Desert Fayum has attracted significant interest as the earliest known centre of agriculture in Egypt. Traditional interpretations of subsistence behaviour and residential mobility have drawn heavily on the studies of lithic assemblages and faunal remains. These interpretations must now be reconsidered in light of lithic material, both from the original excavations and from more recent fieldwork. It emerges that Kom W, the type site for the Neolithic Fayum, was probably a permanent settlement occupied by a community cultivating cereals, in addition to having long-standing practices of hunting and fishing.

The past decade has witnessed an intensification of research into the use of pottery by hunter-gatherers. Long viewed by Western scholars as a marginal practice among these groups, pottery production is now known to have been widespread among prehistoric hunter-gatherers, many of whom practised no other activities associated with agriculture. In emphasising the centrality of ceramics to these communities, however, we risk marginalising those who did not adopt pottery. Here, the authors critically examine a series of different models proposed for hunter-gatherer pottery innovation and adoption within the context of the aceramic communities who inhabited Britain and Ireland during the fifth millennium cal BC.

Ireland has often been seen as marginal in the spread of the Neolithic and of early farming throughout Europe, in part due to the paucity of available data. By integrating and analysing a wealth of evidence from unpublished reports, a much more detailed picture of early arable agriculture has emerged. The improved chronological resolution reveals changing patterns in the exploitation of different plant species during the course of the Neolithic that belie simplistic notions of a steady intensification in farming, juxtaposed with a concomitant decline in foraging. It is possible that here, as in other areas of Europe, cereal cultivation became less important in the later Neolithic.

Plastic entering the archaeological and geological record may be the defining signature of the Anthropocene. Amidst the growing awareness of the role of plastic in marine pollution, this study demonstrates its terrestrial ubiquity. The excavation of two experimentally reconstructed roundhouses built on their original sites at Castell Henllys Iron Age fort, Wales, reveals evidence of 30 years of heritage interpretation and visitor activity. The nature and extent of the cultural material recovered accurately reflects known activities at this heritage site, but also reveals an unexpected amount of plastic debris in archaeological contexts, indicating how, even in well-managed contexts, plastic is entering terrestrial deposits.
