Volunteers are a key part of the archaeological labour force and, with the growth of digital datasets, these citizen scientists represent a vast pool of interpretive potential; yet, concerns remain about the quality and reliability of crowd-sourced data. This article evaluates the classification of prehistoric barrows on lidar images of the central Netherlands by thousands of volunteers on the Heritage Quest project. In analysing inter-user agreement and assessing results against fieldwork at 380 locations, the authors show that the probability of an accurate barrow identification is related to volunteer consensus in image classifications. Even messy data can lead to the discovery of many previously undetected prehistoric burial mounds.

Horses began to feature prominently in funerary contexts in southern Siberia in the mid-second millennium BC, yet little is known about the use of these animals prior to the emergence of vibrant horse-riding groups in the first millennium BC. Here, the authors present the results of excavations at the late-ninth-century BC tomb of Tunnug 1 in Tuva, where the deposition of the remains of at least 18 horses and one human is reminiscent of sacrificial spectral riders described in fifth-century Scythian funerary rituals by Herodotus. The discovery of items of tack further reveals connections to the earliest horse cultures of Mongolia.

Rock art can be useful as a factor in reclaiming Indigenous identities. One example of this phenomenon is work by contemporary artists who explore and integrate rock art in their creations. The author considers how and why a selection of artists in Siberia/Central Asia and Canada use these ancient images.

The Hydrierwerke Pölitz AG was a synthetic-fuel plant of strategic importance to the Nazi war machine. The surrounding area contained labour camps, factories and other military infrastructure. The area was a target for sustained Allied bombardment causing extensive damage to the plant and nearby towns and villages. After the war, the plant's troubled past faded before interest was revived in the 1990s. Here, with the aid of historical aerial photographs and modern remote-sensing methods, the authors document the physical remains of the site, reconstruct its ‘dark history’ and reflect on the significance of the Hydrierwerke for the discourse on neglected and appropriated Second World War heritage.

Collation of satellite imagery and new fieldwork in Şanlıurfa (south-east Türkiye) has revealed large numbers of stone-walled desert kites, some of which may date to the Pre-Pottery Neolithic (c. 9500–7000 BC). The authors briefly explore the potential role of these structures in the processes of early sedentism and monumentality.

Substantial debate surrounds the relative lack of formal burials in Britain during the fifth century AD, which was a key period of social and economic transition following the withdrawal of the Roman army. Here, the authors argue that the ‘missing fifth century’ may be explained, in part, by the continuation of archaeologically invisible mortuary treatments practised in the preceding Iron Age and Roman period. Compilation of published radiocarbon dates from human remains found in cave and riverine contexts demonstrates that a variety of methods for the disposal of the dead—outside of formal cemeteries—existed in the first millennium AD.

The American sweet potato (Ipomoea batatas) is a globally important comestible crop that features prominently in Polynesian lore; however, the timing and mode of its Oceanic transplantation remain obscure. New research from the Māori cultivation site M24/11 in Aotearoa/New Zealand, presented here, offers a re-evaluation of evidence for the early use and distribution of the sweet potato in southern Polynesia. Consideration of plant microparticles from fourteenth-century archaeological contexts at the site indicates local cultivation of sweet potato, taro and yam. Of these, only sweet potato persisted through a post-1650 climatic downturn it seems, underscoring the enduring southern-Polynesian appeal of this hardy crop.

This Andean coast research has identified 113-plus geoglyphs spanning the Formative (1800–100 BC) to the Inka period (AD 1470–1532). The project combined digital technology and Remotely Piloted Airborne Systems to locate the sites. The authors also documented examples of ceramics and intricate road systems and suggest that the finds represent meticulously ritualised landscapes.

After colonising the loess uplands of Bohemia, Moravia and Poland, c. 5500 cal BC, the earliest farming societies (LBK) spread northwest along the Oder valley; then expansion ended at Uckermark, where 119 findspots are located. Newly found sites indicate changes to housing and livestock-farming techniques, in particular the specialised production of dairy products.

Investigations in the Tollense Valley in north-eastern Germany have provided evidence of a large and violent conflict in the thirteenth century BC. Typological analysis of arrowheads from the valley (10 flint and 54 bronze specimens) and comparison with type distributions in Central Europe, presented here for the first time, emphasise the supra-regional nature of the conflict. While the flint arrowheads are typical for the local Nordic Bronze Age, the bronze arrowheads show a mixture of local and non-local forms, adding to the growing evidence for a clash between local groups and at least one incoming group from southern Central Europe.

Calls for the restitution and repatriation of cultural objects continue to escalate. High-profile cases such as the Parthenon Frieze and the Benin Bronzes dominate international news cycles and provoke fierce debate; however, less attention has been paid to items that are quietly returned and to the potential positive outcomes for the institutions on both sides. This article discusses three Southeast Asian case studies to address this lacuna and urges institutions to become more proactive in their engagement with restitution and repatriation claims.

The analysis of coprolites provides direct evidence of resources consumed and may be paired with ethnographic data to elucidate the dietary and medicinal use of plants in archaeological communities. This article combines and contrasts the macroscopic analysis and DNA metabarcoding of 10 coprolites from Bonneville Estates Rockshelter, Nevada, USA. While the results from both methods confirm previous understandings of subsistence practices at the site, minimal overlap in identified taxa suggests that each accesses different components of the consumed material. The two methods should therefore be seen as complementary and employed together, where possible.

High-elevation environments present harsh challenges for the pursuit of agropastoral subsistence strategies and relatively little is known about the mechanisms early communities employed to adapt to such locations successfully. This article presents the sequential carbon and oxygen analysis of archaeological caprine teeth from Bangga (c. 3000–2200 BP), which is approximately 3750masl on the Tibetan Plateau. Made visible through this method, intra-tooth variation in isotopic composition allows insights into herding strategies that possibly included the provisioning of livestock with groundwater and agricultural fodder and summer grazing in saline or marsh environments. Such intensive provisioning differs markedly from lower-elevation agropastoralism.

A dearth of published archaeobotanical data from the Late Bronze Age of western Anatolia limits our understanding of agricultural production in this key area. Recent excavations at Çine-Tepecik provide insights into farming and the political economy in the kingdom of Mira within the lands of Arzawa. Archaeobotanical assemblages indicate that farming was structured to meet both domestic and institutional consumption; the former utilising a wide range of crop species while the latter focused on cereals. Plant remains provide further evidence for a ‘hybrid’ suite of farming practices across western Anatolia and contribute to debate around the spread of broomcorn millet cultivation.

Archaeological cultures present allegories of ethnic identities across the centuries or millennia but such conceptualisations are necessarily incomplete and lack the resolution to explore transitions between cultures. Here, exploration of the archaeological contexts, production methods, stylistic variation and radiocarbon dating of 20 preserved textile fragments facilitates an examination of cultural change at Huaca del Sol (Huacas de Moche, northern Peru). While occupants of the site experienced many outside cultural influences, including those from the highland Wari Empire, continuity in textile traditions suggests that some sense of Moche identity was maintained through the tenth century and after the perceived end of the Moche culture.

Combining non- and minimally invasive archaeological survey, geomorphological methods and linguistic studies enables a better understanding of the dynamic use of the Daugava waterway from the Bronze to the Viking ages. Results indicate a common origin period of many fortified settlements and also identify research questions about cultural fluctuations in the Baltic-Slavic–Scandinavian contact area.

This project focuses on the subsistence strategies of Early Neolithic communities that inhabited the upland region of South Bohemia. Its results reveal a distinctive trajectory for this peripheral area that was colonised significantly later, brought incoming farmers into close contact with hunter-gatherers and made them adapt their conservative farming practices.

Reconstruction of a nineteenth-century cobbled pathway in the village of Aristi provides valuable insights into the material culture and settlement archaeology of Ottoman-era Greece. The authors argue that such small-scale pairing of restoration and archaeological practices in ‘traditional’ settlements could enhance our understanding of Ottoman archaeology without undermining the lived experience of such places.
