The development of complex social organisation and trade networks during the first and second millennia AD in the Sahel region of West Africa has long been hampered by a paucity of reliable data. Investigations at Birnin Lafiya, a large settlement mound of this period on the eastern arc of the Niger River, help to fill this gap. The site can now be placed within its broader landscape, and discoveries of early mud architecture, circular structures, human burial remains, personal ornamentation and striking potsherd pavements can be contrasted with contemporary sites both within the inland Niger region and at Ife to the south.

In recent years, a growing body of research has focused on the importance of water management for ancient Maya societies, and more generally on the cultural and economic significance of water as a resource. But how did this change across the centuries as cycles of drought and sea level rise, together with the growing Maya footprint on the landscape, presented new challenges? As the resolution of climatic records improves, the authors can begin to show in detail how Maya water management responded and adapted to such shifts. This included the manipulation of aguadas and the development of wetland field systems, in the process transforming large areas of the Maya landscape.

The settlement of high-altitude uplands by early agropastoralists demanded specific kinds of social and economic adaptation. Upland valley systems in north-west Argentina were used extensively during the Formative period (200 BC to AD 850). New investigations of the alluvial fans of the Tafí Valley show how the occupation history of the region developed across time and space, demonstrating remarkable stability over 1000 years of agropastoral exploitation. The dense but scattered distribution of early farmers across this landscape highlights household continuity through a period of regional population growth.

The transition from the Formative to the Late period (c. 1000 BP) on the volcanic plateau of Antofagasta de la Sierra in northern Argentina saw various changes in landscape use and settlement pattern. New power structures and social identities appear in the archaeological record in the wake of an increasing emphasis on cultivation and herding, coincident with a regional shift to greater aridity. The novel analysis reported here reveals that these changes also had an impact on pottery technology, notably vessel thickness, and considers the role of technological innovation as both cause and consequence of the changing world experienced by the inhabitants of Antofagasta de la Sierra.

The Cypro-Minoan script was in regular use on the island of Cyprus, and by Cypriot merchants overseas, during the Late Bronze Age. Although still undeciphered, sign-sequences inscribed on miniature copper ‘oxhide’ ingots and on associated clay labels may hold a clue to their purpose. The ingots were previously interpreted as votive offerings inscribed with dedications. Here, it is suggested instead that these extremely pure copper miniatures were produced as commercial samples, and were marked with a brand denoting their high quality and provenance, such as ‘pure Cypriot copper’.

The migration of individuals and populations was a powerful factor in the spread of diseases among early human societies. Analysis of human remains from Tell Masaikh in the Middle Euphrates Valley provides a striking example in what is probably the earliest case of hereditary anaemia. Skeletal changes were consistent with thalassaemia, an uncommon disease in the steppe areas of Syria. Genetic analyses of the remains confirmed the pathological assessment and also suggested that the individual was of Asian descent, from the Indian Peninsula. Such an ancestry could then explain this unusual occurrence of thalassaemia.

Multispectral visual analysis has revealed new information from scarce fragments of a pre-Columbian document excavated in 1932 from a burial at Uaxactun, in Guatemala. The plaster coating from decomposed bark-paper pages of an Early Classic (c. AD 400–600) Maya codex bear figural painting and possibly writing. Direct investigation of these thin flakes of painted stucco identified two distinct layers of plaster painted with different designs, indicating that the pages had been resurfaced and repainted in antiquity. Such erasure and re-inscription has not previously been attested for early Maya manuscripts, and it sheds light on Early Classic Maya scribal practices.

Ship burials are a well-known feature of Scandinavian Viking Age archaeology, but the discovery of 41 individuals buried in two ships in Estonia belongs to the Pre-Viking period and is the first of its kind in Europe. The two crews met a violent end around AD 750, and were buried with a variety of richly decorated weapons, tools, gaming pieces and animal bones. The rich grave goods suggest that this was a diplomatic delegation protected by a cohort of elite warriors. They were armed with swords of Scandinavian design, possibly from the Stockholm-Mälaren region, and stable isotope analysis is consistent with that being the probable homeland of the crew.

Fieldwork at Rendlesham in Suffolk has identified a major central place complex of the early–middle Anglo-Saxon periods. This has particular significance in the light of Bede's eighth-century reference to a ‘royal settlement’ at Rendlesham and the princely burial site at nearby Sutton Hoo. This interim report summarises the archaeology, and considers the wider interpretative issues relating to economic complexity and social diversity.

Maya script—the most elaborate and extensive system of native writing in the New World—was in active use across the Yucatán Peninsula from 300 BC–AD 1700. Maya epigraphy began in the late nineteenth century, developing through the efforts of key figures, often with oblique approaches from other disciplines. Today, the research landscape is increasingly virtual; new discoveries have been combined with greater precision in translation, providing unique access to the complex interactions of Maya society, where the elite shared a language across political boundaries that was incomprehensible to most of their subjects.

For years it has been assumed that tower kivas were observation points, using their high vantage to relay communications across the landscape, or acting as defensive outposts among the local population. Few of these enigmatic structures have been excavated, and archaeologists have consequently turned to landscape survey methods to understand their role and function. Here, the authors contrast visibility and intervisibility within the surrounding viewshed of two tower kivas, Kin Ya'a and Haystack, providing an alternative perspective to traditional interpretations by suggesting that rather than acting as lookout points, they were instead central places built to be looked upon by the surrounding community.

Traditional explanations of Rapa Nui history invoke environmental degradation and warfare to explain the ‘collapse’ of the island's social and economic structure. One element in these reconstructions are the stemmed obsidian points known as mata'a, which some have envisaged as spearheads produced in the context of endemic warfare. Morphometric analysis shows, however, that mata'a were not specifically designed for interpersonal violence but were general purpose tools that may have been used for peaceful tasks such as ritual scarification. This discovery provides further evidence against the theory of the violent collapse of Rapa Nui society.

New research indicates that the royal tomb Paepaeotelea was built c. AD 1300–1400, more than 200 years earlier than its traditional association with Uluakimata I, who ruled when the Tongan polity was at its greatest extent. The large and stylistically complex tomb marks a dramatic increase in the scale of mortuary structures. It represents a substantial mobilisation of labour by this early archaic state, while the geochemical signatures of stone tools associated with the tomb indicate long-distance voyaging. The evidence suggests that the early Tongan state was a powerful and geographically expansive entity, able to rapidly organise and command the resources of the scattered archipelago.

Recent reassessment of the sequence at the highland Maya centre of Kaminaljuyu has led to a substantial chronological revision for Preclassic southern Mesoamerica. The new chronology suggests that various centres on the Gulf Coast, in Chiapas and in the Southern Maya Region experienced political disruption or reorganisation at the end of the Middle Preclassic period around 350 BC. It also shifts the initial rise and height of Kaminaljuyu forward 300 years. These shifts dramatically alter our understanding of sculptural developments in the Southern Maya Region, and emphasise the role of inter-regional interaction in the development of Maya civilisation.

The rock art of Doria Gudaluk (Beswick Creek Cave) in the Northern Territory of Australia has previously provided a valuable lesson in the difficulties of definitive interpretation without local knowledge. Now, newly recorded motifs at the site—some only visible with digital enhancement—highlight the dangers of relating stylistic changes to the replacement of different cultures. When considered in the context of local history, developments in the rock art of Doria Gudaluk during the second half of the twentieth century can be understood as the result of new cultural collaborations between incoming groups and older, local communities.

Modern excavations can sometimes provide surprising new insights on antiquarian finds of metalwork. The Pictish silver hoard from Gaulcross in north-eastern Scotland provides an excellent example. Recent fieldwork, including metal-detecting, has clarified the size and composition of the hoard, and uncovered 100 new silver items, including coins, fragments of brooches and bracelets, ingots and parcels of cut, bent and broken silver known as Hacksilber. Comparisons with other hoards and with Pictish symbol stones illustrate the circumstances and date of deposition, the origin of the silver and the forms of society emerging in Scotland in the post-Roman period.

Skeletal remains from a burial in New South Wales exhibit evidence of fatal trauma, of a kind normally indicative of sharp metal weapons, yet the burial dates to the mid thirteenth century—600 years before European settlers reached the area. Could sharp-edged wooden weapons from traditional Aboriginal culture inflict injuries similar to those resulting from later, metal blades? Analysis indicates that the wooden weapons known as ‘Lil-lils’ and the fighting boomerangs (‘Wonna’) both have blades that could fit within the dimensions of the major trauma and are capable of having caused the fatal wounds.

Analysis of satellite imagery covering Egypt between 2002 and 2013 indicates a significant increase in looting and other damage to archaeological sites. Looting escalated dramatically from 2009 with the onset of the global economic crisis, and intensified still further with the Arab Spring in 2011. This was mirrored by an increased volume of Egyptian artefacts sold at auction, suggesting that looting is driven by external demand as well as by internal economic pressures. Satellite analysis can be used to predict the type and period of antiquities entering the market, thereby providing valuable intelligence for international policing of the illicit antiquities trade.

The Caribbean island of Mona, on a key Atlantic route from Europe to the Americas, was at the heart of sixteenth-century Spanish colonial projects. Communities on the island were exposed to the earliest waves of European impact during a critical period of transformation and the forging of new identities. One of many caves within an extensive subterranean world on the island was marked both by indigenous people and by the first generations of Europeans to arrive in the New World. This account of spiritual encounters provides a rare, personalised insight into intercultural religious dynamics in the early Americas.

The impact of the Spanish conquest and colonisation of Maya territories between 1520 and the 1700s is often regarded as a homogeneous process. Archaeological research conducted over the last 16 years shows this to be far from true. A much more nuanced understanding of the complexities and relationships between Indigenous peoples and the new colonial forces can be achieved by comparing colonised, semi-conquered and unconquered zones within the Maya area. Such an understanding allows Maya archaeology to transcend the simplistic and limiting framework of conquest and collapse that has traditionally typified the narrative of colonial interaction.
