The widespread significance of tobacco in Mesoamerica is documented in historical and ethnographic sources, yet recovery of the organic remains of this plant from archaeological contexts is rare. Here, the authors present evidence for the ritual use of tobacco at Cotzumalhuapa, Guatemala, during the Late Classic period (AD 650–950). Detection of nicotine in residue analysis of three cylindrical ceramic vases recovered from cache deposits near the El Baúl acropolis suggests that these vessels contained tobacco infusions or other liquid preparations. These results suggest an ancient ritual practice involving tobacco for which there was previously no physical evidence in Mesoamerica.

The inability to differentiate skeletal remains belonging to the ferret from those of its wild ancestor, the European polecat, presents a particular challenge for zooarchaeologists which currently hinders a better understanding of ferret domestication history. Using a geometric morphometric approach on the mandible, this study provides a new method to distinguish the two forms. Despite a small sample size and some overlap in the dataset, this method allowed the identification of a (post)medieval specimen from Mechelen (Belgium) as a wild polecat. Results demonstrate that ferrets can largely be distinguished from polecats based on mandibular morphology.

Explanations for the emergence and abandonment of the Chalcolithic Trypillia mega-sites have long been debated. Here, the authors use Gini coefficients based on the sizes of approximately 7000 houses at 38 Trypillia sites to assess inequality between households as a factor in the rise and/or demise of these settlements. The results indicate temporarily reduced social inequality at mega-sites. It was only after several generations that increased social differentiation re-emerged and this may explain the subsequent abandonment of the mega-sites. The results indicate that increases in social complexity need not be associated with greater social stratification and that large aggregations of population can, for a time at least, find mechanisms to reduce inequality.

In this article, the authors present an analysis of radiocarbon dates from a stratified deposit at the Greek Geometric period settlement of Zagora on the island of Andros, which are among the few absolute dates measured from the period in Greece. The dates assigned to Greek Geometric ceramics are based on historical and literary evidence and are found to contradict absolute dates from the central Mediterranean which suggest that the traditional dates are too young. The results indicate the final period at Zagora, the Late Geometric, should be seen as starting at least a century earlier than the traditional date of 760 BC.

Modern and contemporary archaeology, the French equivalent of historical archaeology, emerged in the 1970s. Subsequent attempts at theorising this sub-discipline have been hindered by a lack of broad professional recognition and funding. While the archaeology of the sixteenth to eighteenth centuries is now more widely recognised in France, studies of the post-nineteenth-century period remain limited to a few specific contexts. Here, the author offers an overview for the Anglophone readers of modern and contemporary archaeology in France and argues that greater theorisation, cross-fertilisation with other archaeological traditions and a diversification of the range of themes considered might enhance recognition of this sub-discipline within and beyond France.

The settlement of Ban Non Wat charts the transition from the Neolithic to the Bronze Age in north-eastern Thailand. Examination of grave inclusions and mortuary treatment at this important site allows insights into social change during this key period. Increasing complexity and the inclusion of exotic items in the mortuary treatment of some individuals early in the Bronze Age is suggested to show the rise of a lineage of aggrandisers who controlled access to these symbolic articles. But, the author argues, their elevated status was ephemeral, forfeited as local bronze casting became established.

The remains of black henbane (Hyoscyamus niger) are relatively common at archaeological sites as it grows naturally around settlements in north-western Europe. All parts of the plant may be used as a medicine or a narcotic but its natural prevalence in built environments makes it difficult to interpret any intentionality behind its presence in the archaeological record. Evidence of the deliberate collection and use of black henbane seeds in the Roman Netherlands is presented here for the first time. Examination of Classical texts and interrogation of the archaeobotanical data allow the authors to place the discovery at Houten-Castellum of a hollowed bone containing hundreds of black henbane seeds within the context of the wider Roman understanding of the plant and its properties.

Exogamous marriage alliances involving royal women played a prominent role in the conversion of the Anglo-Saxon kingdoms to Christianity in the seventh century AD. Yet the large number of well-furnished female burials from this period suggests a broader change in the role of women. The authors present the results of isotopic analysis of seventh-century burials, comparing male and female mobility and the mobility of females from well-furnished versus poorly/unfurnished burials. Results suggest increased mobility during the Conversion Period that is, paradoxically, most noticeable among women buried in poorly furnished graves; their well-furnished contemporaries were more likely to have grown up near to their place of burial.

Durable architecture is a hallmark of Polynesian chiefdoms, associated with centralised control of residential and agricultural land. Previous work in West Polynesia has indicated a relatively late date for the onset of such construction activity—after AD 1000—suggesting that political development was influenced by events such as post-colonisation migration. The authors report new dating evidence from the excavation of a large earth mound on the island of Tongatapu. Its construction 1500 years ago indicates that, in contrast to previous findings, well-developed chiefdoms and field monuments probably dominated the landscapes of West Polynesia substantially prior to the colonisation of more easterly island nations.

Relatively few examples of Palaeohispanic writing have been recovered from the Vasconic territories of present-day Navarre, leading to the assumption that the Vascones were a pre-literate society. Here, the authors report on an inscription on a bronze hand recovered at the Iron Age site of Irulegi (Aranguren Valley, Navarre) in northern Spain. Its detailed linguistic analysis suggests that the script represents a graphic subsystem of Palaeohispanic that shares its roots with the modern Basque language and constitutes the first example of Vasconic epigraphy. The text inscribed on this artefact, which was found at the entrance of a domestic building, is interpreted as apotropaic, a token entreating good fortune.

Excavations at Yeghegis-1, a rockshelter in southern Armenia, reveal long-term human habitation from the late fifth to mid-fourth millennia BC. Here, the authors present a preliminary overview of the materials recovered from the site and highlight the potential of ongoing research to shed light on Chalcolithic human lifeways in the region.

Recent research has considered the relationship between Stonehenge and sites in south-west Wales, raising questions about whether the first monument at Stonehenge copied the form of an earlier stone circle at Waun Mawn and how the relationship between these sites was connected with the transport of bluestones between the different regions. But Stonehenge and Waun Mawn are not the only prehistoric sites in Britain and Ireland that share architectural elements and hint at social connections across vast distances of land and sea. This debate article explains how the questions raised about these Late Neolithic monuments can and should be applied to other monumental complexes to explore this insular phenomenon.

PEPAdb (Prehistoric Europe's Personal Adornment Database) is a long-term, open-ended project that aims to improve access to archaeological data online. Its website (https://pepadb.us.es) publishes and analyses datasets about prehistoric personal adornment, drawing on the results of various research projects and bibliographic references.

In 2023, prospection of a dried-out lake near Papowo Biskupie in north-central Poland identified substantial deposits of bronze artefacts. Excavation revealed further deposits and dozens of human skeletons that date from 1000–400 BC, suggesting that the site held particular significance as a place for sacrificial offerings in the Lusatian culture.

Comparative studies of inequality based on archaeological data rely on universal notions of status or prestige that are not always meaningful across diverse cultural contexts. Here, the authors evaluate three broadly contemporaneous urban communities (Marothodi, Molokwane and Kaditshwene) in the southern African interior in the eighteenth and nineteenth centuries AD. The study combines a statistical measure of inequality, the Gini coefficient, with insights from the rich ethnohistorical archives of African knowledge systems. The results suggest markedly different levels of inequality, but contextualisation points to divergent social strategies for settlement organisation and for managing sociopolitical insecurity. The findings raise important questions about cross-cultural indices of social inequality.

Previous archaeobotanical research in Southwest Asia focused on the Neolithic ‘founder crops’. The Founders project revisits this concept and the economic role these species played in the development of agriculture. To achieve this aim, archaeological food remains are studied and culinary practices of the last hunter-gatherers and first farmers are evaluated.

The north coast of Peru is among the most extensively surveyed regions in the world, yet variation in research questions, sampling strategies and chronological and geospatial controls among survey projects makes comparison of disparate datasets difficult. To contextualise these issues, the authors present a systematic survey of satellite imagery focusing on hilltop fortifications in the Jequetepeque and Santa Valleys. This digital recontextualisation of pedestrian survey data demonstrates the potential of hybrid methodologies to substantially expand both the identification of archaeological sites within difficult terrain and, consequently, our understanding of the function of defensive sites.

Fog oases (lomas) present pockets of verdant vegetation within the arid coastal desert of Andean South America and archaeological excavation within some of the oases has revealed a long history of human exploitation of these landscapes. Yet lomas settlements are under-represented in archaeological datasets due to their tendency to be located in remote inter-valley areas. Here, the authors employ satellite imagery survey to map the locations of anthropogenic surface features along the central Peruvian coast. They observe two categories of archaeological features, large corrals and clustered structures, and document a concentration of settlement features within lomas landscapes that suggests a pre-Hispanic preference for both short- and long-term occupation of these verdant oases.

The GINI project investigates the dynamics of inequality among populations over the long term by synthesising global archaeological housing data. This project brings archaeologists together from around the world to assess hypotheses concerning the causes and consequences of inequality that are of relevance to contemporary societies globally.
