The risk to surface archaeological sites posed by heavy machinery has grown significantly, and stone-tool assemblages are particularly susceptible to alteration that may be difficult to recognise. Indeed, the impact of industrial machines on surface scatters of lithic material has not yet been explored. Here, an analytical experiment is used to explore the ways in which machine action can affect a test assemblage resembling a typical Stone Age scatter. The results demonstrate that while formal tool types are not easily replicated through machine action, the creation of assemblages that resemble archaeological debitage poses a much greater challenge for archaeologists.

Recent survey and excavation conducted in the Mil Plain region of the southern part of the Republic of Azerbaijan challenges traditional notions of Neolithic sedentism. Here, the authors present their findings, and propose that prior to its abandonment towards the end of the sixth millennium BC, the occupation of the region was comprised of numerous highly variable short-term sites and multi-mounded sites (Qarabel Tepe), as well as anchoring sites (Kamiltepe). This indicates multi-scalar patterns of mobility of a much more complex nature than had previously been supposed, making this region quite unique for the Late Neolithic of South-western Asia.

The study of the exploitation of animals for traction in prehistoric Europe has been linked to the ‘secondary products revolution’. Such an approach, however, leaves little scope for identification of the less specialised exploitation of animals for traction during the European Neolithic. This study presents zooarchaeological evidence—in the form of sub-pathological alterations to cattle foot bones—for the exploitation of cattle for the occasional pulling of heavy loads, or ‘light’ traction. The analysis and systematic comparison of material from 11 Neolithic sites in the Western Balkans (c. 6100–4500 cal BC) provides the earliest direct evidence for the use of cattle for such a purpose.

The Caribbean coast of Nicaragua has witnessed relatively little archaeological research. In the last decade, however, there has been a substantial effort to record regional archaeological sites. First excavated in the early 1970s, the Angi shell-matrix site has been subject to new investigations, which have identified the first burial to be recorded on the Nicaraguan Caribbean coast. Although collagen preservation was insufficient for direct radiocarbon dating, samples obtained from surrounding deposits date the burial to c. 3900 BC. This represents both the earliest archaeological feature recorded to date on the Caribbean coast of Nicaragua and the oldest-known human remains from the region.

The Paracas culture of Late Formative Period south coastal Peru (c. 900–100 BC) is renowned for its elaborate and colourful ceramics—particularly those decorated using the post-fire painting technique. The materials and the methods used to achieve post-fire painting, however, remain elusive. To investigate the evolution of, and regional variation in, this technology, the authors deploy a range of techniques to analyse a sample of Paracas ceramics curated in museum collections. The results indicate diachronic and regional variations in the paint binders and colourants used by the Paracas potters, which correlate with changes in vessel form and iconography over time.

Extensively excavated village sites from the Chinese Bronze Age are rare. Information emerging from the analysis of the small Anyang-period village site of Guandimiao, however, challenges widely held assumptions concerning the Shang polity at Anyang and its hierarchical lineages based on war and sacrifice. Evidence for specialised pottery production and the presence of artefacts imported from Anyang suggest an unexpected degree of regional economic integration. Guandimiao is emerging as a site of revolutionary importance for understanding Anyang-period Shang political and economic networks, and in its significance to both Chinese archaeology and the study of early complex societies more generally.

The South Caucasus occupies the divide between ancient Mesopotamia and prehistoric Europe, and was thus crucial in the development of Old World societies. Chronologies for the region, however, have lacked the definition achieved in surrounding areas. Concentrating on the Tsaghkahovit Plain of north-western Armenia, Project ArAGATS's multi-site radiocarbon dataset has now produced Bayesian modelling, which provides tight chronometric support for tracing the transmission of technology, population movement and social developments that shaped the Eurasian Bronze and Iron Ages.

Lying on the north-west coast of Sri Lanka, the ancient port of Mantai was ideally situated as a ‘hub’ for trade between East and West from the first millennium BC onwards. Excavations at the site were interrupted by civil war in 1984, delaying publication of these results and leading to the underestimation of Mantai's importance in the development of Early Historic Indian Ocean trade. Renewed excavations in 2009–2010 yielded extensive archaeobotanical remains, which, alongside an improved understanding of the site's chronology, provide important new insights into the development of local and regional trade routes and direct evidence for early trade in the valuable spices upon which later empires were founded.

The seventh-century AD switch from gold to silver currencies transformed the socio-economic landscape of North-west Europe. The source of silver, however, has proven elusive. Recent research, integrating ice-core data from the Colle Gnifetti drill site in the Swiss Alps, geoarchaeological records and numismatic and historical data, has provided new evidence for this transformation. Annual ice-core resolution data are combined with lead pollution analysis to demonstrate that significant new silver mining facilitated the change to silver coinage, and dates the introduction of such coinage to c. AD 660. Archaeological evidence and atmospheric modelling of lead pollution locates the probable source of the silver to mines at Melle, in France.

Archaeological evidence for stilt-house settlements, or pile dwellings, has been recorded in diverse wet environments around the world. The first-millennium AD stilt-house villages in the Brazilian state of Maranhão, however, are poorly known. Difficulties in conducting archaeological investigations in seasonally flooded areas have restricted our ability to understand the societies that lived in these unique settlements. The results of recent fieldwork using non-invasive techniques to map, date and characterise these sites point towards a number of similarities and differences in their spatial organisation, material culture and social structure.

The Amazon is one of the few independent centres of plant domestication in the world, yet archaeological and ethnographic evidence suggest a relatively recent transition to agriculture there. In order to make sense of this time lag, the authors propose the use of the concept of ‘familiarisation’ instead of ‘domestication’, to explain Amazonian plant management, and the long-term relationship between plants and people in the region. This concept allows them to cast a fresh eye over ancient and contemporary patterns of plant cultivation and management that may be distinct to the ones described for the Old World.

During the First World War (1914–1918), the construction and maintenance of the Western Front in North-west Europe required huge quantities of timber. Although archaeological investigations regularly uncover well-preserved wooden structures and objects, studies of the timber's provenance are rare. The authors combine archival research with wood-species identification and tree-ring analysis of a large assemblage of wooden objects excavated from former trenches on the Western Front. The results show that most objects and structures were made using fast-growing European species, with evidence for the small-scale but continuous importation of North American timber.

In a recent Antiquity article, Ammerman et al. (2017) suggest that three radiocarbon dates on seventh- or eighth-century AD samples obtained by coring beneath St Mark's Basilica—including two peach stones—illuminate the earliest settlement of the historic centre of Venice. Excavations at several other locations, however, have yielded in situ settlement remains at least as old as the peach stones, some of which are securely dated by a floating tree-ring chronology and radiocarbon dates from stratified structural samples. Here, the authors summarise this evidence, and propose that a large area of the historic centre may have been settled by, or during, the mid seventh century AD.
