The relative scarcity of ancient Arabian rock reliefs has been a significant barrier to understanding the development, function and socio-cultural context of such art. The recently discovered ‘Camel Site’ in northern Arabia depicts, for the first time, life-sized camelids and equids carved in low- and high-relief. Analysis and stylistic comparison of the art suggest a distinct Arabian tradition, which perhaps drew upon Nabataean and Parthian influences. That this isolated and seemingly uninhabitable site attracted highly skilled rock-carvers is striking testimony to its importance for surrounding populations. Perhaps serving as a boundary marker or a place of veneration, the Camel Site offers important new evidence for the evolution of Arabian rock art.

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.

Archaeological evidence for a Sasanian presence in the ‘Uman region of Eastern Arabia is sparse. Recent excavations at the site of Fulayj in Oman have, however, revealed it to be a Late Sasanian fort, the only securely dated example in Arabia, or indeed on the western shores of the Indian Ocean more generally. AMS dating supports the ceramic chronology proposed for the site, demonstrating occupation until the Islamisation of South-eastern Arabia in the early seventh century AD, and also briefly into the very Early Islamic period. Fulayj fort provides new insights into Sasanian military activities during this crucial period of Arabian history.

The origins of ancient states is an important archaeological research topic that illuminates the precursors of modern nations. Public buildings, as is the case today, created urban settings in which political, administrative and religious functions were undertaken. This investigation of the ancient Mesoamerican kingdom of Izapa reveals a network of urban centres laid out according to shared design principles. While the capital city of Izapa has long been known, the authors’ research reveals, for the first time, the entire Izapa kingdom. This work provides an important new insight into the origins of political hierarchy and urban life in pre-Hispanic Mesoamerica.

Chinese civilisation has long been assumed to have developed in the Central Plains in the mid to late second millennium BC. Recent archaeological discoveries at the Bronze Age site of Shimao, however, fundamentally challenge traditional understanding of ‘peripheries’ and ‘centres’, and the emergence of Chinese civilisation. This research reveals that by 2000 BC, the loess highland was home to a complex society representing the political and economic heartland of China. Significantly, it was found that Later Bronze Age core symbols associated with Central Plains civilisations were, in fact, created much earlier at Shimao. This study provides important new perspectives on narratives of state formation and the emergence of civilisation worldwide.

The European Migration Period (c. AD 400–550) was characterised by political, social and economic instability. Recent excavations at Sandby borg ringfort on the island of Öland in Sweden have revealed indisputable evidence of a massacre which occurred at that time. Osteological, contextual and artefactual evidence strongly suggest that the fort was abandoned immediately following the attack and was left undisturbed throughout antiquity. Sandby borg offers a unique snapshot of domestic life and abrupt death in the Scandinavian Migration Period, and provides evidence highly relevant to studies of ancient conflict, and on social and military aspects of Iron Age and Migration Period societies.

The Christianisation of Ireland in the fifth century AD produced distinct monastic practices and architectural traditions. Recent research on Inishark Island in western Ireland illuminates the diverse material manifestations of monasticism and contributes to the archaeological analysis of pilgrimage. Excavations revealed a ritual complex (AD 900–1100) developed as both an ascetic hermitage and a pilgrimage shrine. It is argued that monastic communities designed ritual infrastructure to promote ideologies of sacred hierarchy and affinity that legitimated their status and economic relations with lay worshippers. In a global context, this research emphasises how material and spatial settings of pilgrimage can accommodate and construct social distinctions through patterns of seclusion, exclusion and integration in ritual.

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.

New evidence from the rockshelter site of Aru Manara, on the island of Morotai, in the northern Moluccas, East Indonesia, suggests an earlier than previously assumed date for extensive interactions between this area of Southeast Asia and the wider Pacific. Shared mortuary customs and associated ceramic grave goods, along with other practices such as megalithic traditions, appear to start in the Late Neolithic, but become more widespread and consolidated in the Early Metal Age. Excavations at Aru Manara show that the northern Moluccas may have figured prominently in the newly established network of interaction evidenced at this time, making it an important location in the spread and dispersal of people and culture throughout Island Southeast Asia and into Oceania.

The ‘Birka dragon’ symbol is synonymous with the famous Viking Age town of that name, an association born from the 1887 discovery of a casting mould depicting a dragonhead. Recent excavations in Black Earth Harbour at Birka have yielded a dress pin that can, almost 150 years later, be directly linked to this mould. This artefact introduces a unique ‘Birka style’ to the small corpus of known Viking Age dragonhead dress pins. The authors discuss and explore the artefact's manufacture, function and chronology, and its connections to ship figureheads.

Archaeological evidence for the Viking Great Army that invaded England in AD 865 is focused particularly on the area around St Wystan's church at Repton in Derbyshire. Large numbers of burials excavated here in the 1980s have been attributed to the overwintering of the Great Army in AD 873–874. Many of the remains were deposited in a charnel, while others were buried in graves with Scandinavian-style grave goods. Although numismatic evidence corroborated the belief that these were the remains of the Great Army, radiocarbon results have tended to disagree. Recent re-dating of the remains, applying the appropriate marine reservoir correction, has clarified the relationship between the interments, and has resolved the previous uncertainty.

The vast mortuary complexes of the Xiongnu, the world’s first nomadic empire (c. 200 BC–AD 100), were important statements of elite power and ritual commemoration in Inner Asia. Very few of the features that accompanied the main tombs, however, have been fully excavated and investigated. This study is one of the first to assess completely the small archaeological features—and associated faunal remains—that surround the more monumental structures, features that intimate substantial investments in, and ritual activities around, these mortuary arenas. This research provides an important contribution to the understanding of the social politics of ritual practices and the development of complex institutions in steppe pastoral societies.

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.

A newly discovered jade head pendant from the Guatemalan site of Ucanal illuminates a rarely considered element of Classic Maya royal ceremonies: weight. The largest and probably the heaviest of its kind, this pendant is a rare example of Classic Maya belt ornaments. Finely carved jade ornaments symbolised the prestige and wealth of elite officials, but were also metaphors for the weighty burdens of office. This paper considers the phenomenological role of jade jewellery, which would have encumbered Maya royalty greatly during public ceremonies. While such a perspective underscores the ritual work of elites, an analytical focus on weight also highlights the anonymous people who carried burdens.

This article provides results from a full morphological, use-wear and microfossil residue analysis of a notched bone tool made from a camelid scapula, which was recovered from the late pre-Hispanic site of Boyo Paso 2 (1500–750 years BP, Sierras of Córdoba, Argentina). The use-wear pattern showed striations similar to those recorded in experimental bone tools used for scraping activities. The starch grains found on the active or working edge are similar to the Andean tuber crop Oxalis tuberosa, and suggest that the tool was used for peeling wild or domesticated Oxalis sp. tubers, thereby questioning the disproportionate attention directed towards maize in late pre-Hispanic economies.

The role of pre-contact indigenous peoples in shaping contemporary multi-ethnic society in Hispaniola (Haiti and the Dominican Republic), and elsewhere in the Caribbean, has been downplayed by traditional narratives of colonialism. Archaeological surveys in the northern Dominican Republic and open-area excavations at three (pre-)Contact-era Amerindian settlements, combined with historical sources and ethnographic surveys, show that this view needs revising. Indigenous knowledge of the landscape was key to the success of early Europeans in gaining control of the area, but also survives quite clearly in many aspects of contemporary culture and daily life that have, until now, been largely overlooked.

Despite the high degree of technological sophistication visible in other aspects of urban engineering, the archaeology of pre-Columbian Mesoamerica has revealed curiously few examples of bridges or formal, permanent water-crossing structures. The ancient city of Cotzumalhuapa, where at least five such structures have been identified, is a notable exception. The author reviews the archaeological and historical evidence for these bridges, and reflects upon the diversity of engineering technologies that they reveal. Although it remains unclear why bridges are absent at many other contemporaneous sites, these examples offer a fascinating glimpse into the urban planning of structured mobility in Mesoamerica.

The date of unique symbolic carvings, from various contexts across north and east Scotland, has been debated for over a century. Excavations at key sites and direct dating of engraved bone artefacts have allowed for a more precise chronology, extending from the third/fourth centuries AD, broadly contemporaneous with other non-vernacular scripts developed beyond the frontiers of the Roman Empire, to the ninth century AD. These symbols were probably an elaborate, non-alphabetic writing system, a Pictish response to broader European changes in power and identity during the transition from the Roman Empire to the early medieval period.

The development of an advanced stone-working technology in the Aegean Bronze Age is suggested by the putative Mycenaean pendulum saw. This device seems to have been used to cut through hard sedimentary rock at a number of sites on the Greek mainland and, according to some scholars, also in central Anatolia. As no pendulum saws are preserved in the archaeological record, understanding the machine relies on preserved tool marks and experimental research. This paper presents the results of stone-cutting experiments conducted with a modern reconstruction of a pendulum saw. The research investigates blade shape, size, design and the mechanics of the device, while questioning the accuracy of earlier reconstructions.

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.
