Across Eurasia, horse transport transformed ancient societies. Although evidence for chariotry is well dated, the origins of horse riding are less clear. Techniques to distinguish chariotry from riding in archaeological samples rely on elements not typically recovered from many steppe contexts. Here, the authors examine horse remains of Mongolia's Deer Stone-Khirigsuur (DSK) Complex, comparing them with ancient and modern East Asian horses used for both types of transport. DSK horses demonstrate unique dentition damage that could result from steppe chariotry, but may also indicate riding with a shallow rein angle at a fast gait. A key role for chariots in Late Bronze Age Mongolia helps explain the trajectory of horse use in early East Asia.

Archaeological studies of belief, ideology and commemorative strategies in Ireland, and elsewhere in Europe, neglect the continuation of cremation far beyond the supposed fifth-century AD threshold for the shift to inhumation under the influence of Christianity. A database of radiocarbon dates from first-millennium AD Ireland permits the identification of new patterns in early medieval (AD 400–1100) mortuary practices, including a new phase of cremation. The authors discuss archaeological and historical implications to demonstrate how data-driven approaches can enhance and challenge established metanarratives. They also highlight serious methodological and interpretative issues that these data pose for current narrative frameworks, and their influence on post-excavation strategies.

Turtles are important barometers of human impact on marine biodiversity. Very little, however, is known about the deep history of human-turtle interactions and whether this is reflected in the present-day vulnerability of Mediterranean turtle populations. Here, the authors critically assess the zooarchaeological evidence for the nature and intensity of past human interactions with green, loggerhead turtles and Nile soft-shell turtles in the Eastern Mediterranean. Species and sex identifications, estimates of relative abundance, and size reconstructions at five coastal archaeological sites demonstrate the variety in interactions, from turtle capture to processing, and allow informative comparisons with present-day distributions of these species across the region.

Deliberately deposited (or cached) objects are ubiquitous in the archaeological record, yet they are often classified under different categories, such as hoards, structured deposits, grave goods and cenotaph burials, and interpreted according to different criteria. Drawing on contemporary attitudes to death, dying and bereavement, and using later prehistoric Britain as a case study, this article brings the analysis of these objects together within a single interpretive framework, which asserts that much of this material represents the ‘problematic stuff’ left behind by the dead. This approach forces us to reconsider the traditional boundaries drawn between different aspects of the archaeological record and demonstrates the value that emotion has in our interpretations of past societies.

The expansion of the Umayyad and Abbasid Caliphates (seventh to ninth centuries AD) brought diverse regions from the Indus Valley to the Eurasian Steppe under hegemonic control. An overlooked aspect of this political process is the subsequent translocation of species across ecological zones. This article explores species introduction in the early Islamic world, presenting the first archaeological evidence for domestic water buffalo in the Caucasus—identified using zooarchaeological and ZooMS methods on material from the historical site of Bardhaʿa in Azerbaijan. We contextualise these finds with historical accounts to demonstrate the exploitation of medieval marginal zones and the effects of centralised social reorganisation upon species dispersal.

A common feature of successful ancient states was the role of elites in maintaining and regulating socioeconomic structures and, in particular, emphasising their own social difference. The Wari (AD 600–1000) are considered the earliest expansive state in South America, and excavations have demonstrated the rich variety of exotic goods imported from across the region into the polity's heartland. Here, the authors argue that the importation of raw materials, plants, animals and people from distant regions was crucial for defining and sustaining Wari social differentiation and ideology. They emphasise the importance of studying material provenance and their archaeological contexts in order to understand the role of exotic goods in legitimising ruling groups in ancient states.

Important discoveries over the past 15 years in the coastal area between Huelva and Málaga in Spain have illuminated the beginnings of the eighth-century BC Phoenician diaspora into the Western Mediterranean. Here, the authors combine Bayesian modelling of recently published radiocarbon dates with the latest archaeological data to investigate the Phoenician presence in southern Iberia. Their assessment of its significance for the Late Bronze and Early Iron Ages in the Western Mediterranean contributes not only to understanding the integration of the Phoenicians into local communities, but also to apprehending the mechanisms of colonisation and pre-colonial situations elsewhere in protohistoric Europe and other world contexts.

The origin of alphabetic script lies in second-millennium BC Bronze Age Levantine societies. A chronological gap, however, divides the earliest evidence from the Sinai and Egypt—dated to the nineteenth century BC—and from the thirteenth-century BC corpus in Palestine. Here, the authors report a newly discovered Late Bronze Age alphabetic inscription from Tel Lachish, Israel. Dating to the fifteenth century BC, this inscription is currently the oldest securely dated alphabetic inscription from the Southern Levant, and may therefore be regarded as the ‘missing link’. The proliferation of early alphabetic writing in the Southern Levant should be considered a product of Levantine-Egyptian interaction during the mid second millennium BC, rather than of later Egyptian domination.

Barrows are a prominent feature of Britain's Bronze Age landscape. While they originated as burial monuments, they also appear to have acquired other roles in prehistory. British prehistorians, however, have been hampered in their interpretations of these monuments, as they are wary of speculating about how Bronze Age people might have conceptualised their dead. Here, the authors suggest that a recurring pattern of inversion is significant. They use Conceptual Metaphor Theory to argue that Bronze Age people in Britain saw their dead inhabiting an inverted underworld directly beneath the surface of the earth. This interpretation would explain not only burial practices, but also some of the barrows’ other apparent functions, such as guarding boundaries and controlling routeways.

Dietary studies can offer insight into the effects of imperial rule on colonised populations. Inka expansion was associated with change in agricultural production and diet, including greater emphasis on maize. This article presents stable isotope analyses of ten individuals from two locations in Antofagasta de la Sierra, Argentina. AMS dating assigns one site to the start of the Inka period and one to the end. Despite diachronic changes in material culture, isotope analyses indicate that maize remained relatively unimportant in local diet. Given the symbolic value of maize in the Inka world, this lack of dietary change suggests limited imperial influence over local agricultural production and diet.

Between the sixth and the eighth centuries AD, the practice of depositing grave goods was almost entirely abandoned across Western Europe. To date, however, explanations for this change have focused on local considerations. By collating data from 237 cemeteries from across Western Europe, this article assesses the spatial and chronological development of this phenomenon. Beginning in the mid sixth century, the process accelerated towards the end of the seventh century, before near complete abandonment across the region by the following century. This widespread and rapid transition is interpreted in light of evidence for trade and connectivity, which facilitated the swift diffusion of this and other cultural practices across the region.

The role of ferrous metallurgy in ancient communities of the Circumpolar North is poorly understood due, in part, to the widespread assumption that iron technology was a late introduction, passively received by local populations. Analyses of two recently excavated sites in northernmost Sweden, however, show that iron technology already formed an integral part of the hunter-gatherer subsistence economy in Northern Fennoscandia during the Iron Age (c. 200–50 BC). Such developed knowledge of steel production and complex smithing techniques finds parallels in contemporaneous continental Europe and Western Eurasia. The evidence presented raises broader questions concerning the presence of intricate metallurgical processes in societies considered less complex or highly mobile.

Extensively worked in antiquity, Skouriotissa remains the only active copper mine on the island of Cyprus. The modern, open-cast operation, however, has almost completely obliterated the earlier mining landscape. Here the authors report the results of investigations, including dating, of the ancient topography of the mine. They incorporate spatial data derived from archival sources, recent fieldwork and absolute dating into a geographical information system to reconstruct the ancient mining landscape around Skouriotissa. Their approach holds promise for understanding other mining regions in Cyprus and beyond, by providing an example of how diverse source material can be used to reconstruct landscapes now destroyed or buried by open-cast mining operations.

The Koźle Basin in Poland was radically transformed by aerial bombardment during the Second World War. Today, the region has approximately 6000 well-preserved bomb craters with diameters ranging from 5–15m and depths often exceeding 2m. Combining remote-sensing data and fieldwork with historical accounts, this article analyses these craters, demonstrating that their varied morphologies derive from the weight of the bombs that created them, and on the type and moisture content of the soil on which the bombs fell. Based on their results, the authors issue a call for the official protection of the Koźle landscape, which has particular historical, educational and ecological value.

Machu Picchu, in Cuzco, is one of the most famous archaeological sites in South America. The precise dating of the monumental complex, however, relies largely on documentary sources. Samples of bone and teeth from individuals buried in caves at four cemeteries around Machu Picchu form the basis for a new programme of AMS radiocarbon-dating. The results show that the site was occupied from c. AD 1420–1532, with activity beginning two decades earlier than suggested by the textual sources that associate the site with Emperor Pachacuti's rise to power in AD 1438. The new AMS dates—the first large set published for Machu Picchu—therefore have implications for the wider understanding of Inca chronology.

The COVID-19 pandemic is creating a viral archive—an archaeological record of history in the making. One aspect of this archive is increased environmental pollution, not least through the discarded facemasks and gloves that characterise the pandemic. This article—directed specifically at archaeologists—argues that an archaeological perspective on ‘COVID waste’ using social media analysis can help to highlight environmental pollution, and that by giving this waste the status of archaeological material and working with other disciplines, archaeologists can contribute to sustainable, policy-led solutions to combat environmental pollution.

The human remains recovered from the famous Bjerringhøj Viking Age burial in Denmark have been missing for more than 100 years. Recently, an assemblage of bones resembling those recorded at Bjerringhøj—some with adherent textiles—were discovered in a misplaced box in the National Museum of Denmark. Here, the authors use new skeletal and comparative textile analyses, along with radiocarbon dating, to confirm that the bones are indeed those from the Bjerringhøj burial. This rediscovery offers new data for interpreting Viking Age clothing, including the presence of long trousers, and emphasises the importance of reinvestigating old archaeological collections housed within museums and archives.

The highland Wari (AD 600–1000) were an influential and expansive Andean civilisation, yet the nature and organisation of Wari power is debated. For example, it is suggested that coastal Nasca was governed by Wari, but doubts remain about its role in the region. Recent excavations at Huaca del Loro in Nasca have uncovered rectilinear compounds, a D-shaped temple, a large cemetery and a domestic area. The authors suggest that this evidence reflects Wari colonisation, undertaken during a period of primary expansion, on a site with long-established ties between Wari and Nasca. The use of multiple colonising strategies and local responses may reflect imperial situations in other world civilisations.

Across Europe early medieval archaeologists have long recognised significant numbers of graves displaying evidence for the intentional post-burial disturbance of skeletons and artefacts. The practice of reopening and manipulating graves soon after burial, traditionally described—and dismissed—as ‘robbing’, is documented at cemeteries from Transylvania to southern England. This article presents a synthesis of five recent regional studies to investigate the evidence of and the motivations for the reopening of early medieval graves. From the later sixth century AD, the reopening of individual graves and removal of selected artefact types rapidly became part of the shared treatment of the dead across this wide area.

Chacmools are a distinctive sculptural form associated with the Mesoamerican cities of Chichen Itza and Tula. A recently excavated sculpture found at Las Mercedes in Costa Rica, over 2000km to the south, closely resembles the Mesoamerican chacmools. Comparing this new chacmool-like sculpture with similar examples at the American Museum of Natural History and the National Museum of Costa Rica, the authors demonstrate that these sculptures were common in lower Central America, and propose a connection between Central America and Mesoamerica dating back to AD 1000. They interpret the Costa Rican chacmools as ritual furniture employed by local chiefs to enhance their power and prestige through the enactment of Mesoamerican-inspired rituals.
