In response to Timothy Darvill's article, ‘Mythical rings?’ (this issue), which argues for an alternative interpretation of Waun Mawn circle and its relationship with Stonehenge, Parker Pearson and colleagues report new evidence from the Welsh site and elaborate on aspects of their original argument. The discovery of a hearth at the centre of the circle, as well as further features around its circumference, reinforces the authors’ original interpretation. The authors explore the evidence for the construction sequence, which was abandoned before the completion of the monument. Contesting Darvill's argument that the Aubrey Holes at Stonehenge originally held posts, the authors reassert their interpretation of this circle of cut features as Bluestone settings.

Armed conflicts frequently result in the damage or destruction of archaeological heritage. The occupation by ISIS of parts of Iraq and Syria is no exception. Here, the authors present the results of work focused on Nineveh, as part of a wider research initiative to monitor damage inflicted by ISIS at archaeological sites in northern Iraq. Combining satellite imagery, low-level aerial photography and ground-based reconnaissance, the project presents a condition assessment of Nineveh, as well as a new topographic map of the city. The results demonstrate that a few high-profile acts of deliberate vandalism were accompanied by much more extensive damage caused by construction and rubbish dumping extending across substantial parts of the site.

Salt is an essential commodity; archaeological remains around the world attest to the importance of its production, exchange and consumption. Often located in coastal locations, many production sites were submerged by rising seas, including the Paynes Creek Salt Works on the southern Belize coast. Survey and excavation of these sites has identified ‘kitchens’ for brine boiling, as well as Terminal Classic residential structures at Ek Way Nal. The authors report the discovery of an earlier residential building alongside salt kitchens at the nearby site of Ta'ab Nuk Na. This finding indicates that surplus household production began during the Late Classic, when demand for salt from inland cities was at its peak.

Studies of ancient Mediterranean trade and economy have made increasing use of sophisticated modelling and network analyses of shipwreck evidence. The dating of most of these wrecks, however, is based solely on assessments of associated ceramic material, especially transport amphorae. The resulting dates are approximate at best, and, as the example of the recently investigated Mazotos ship highlights, sometimes incorrect. Here, the authors describe a widely applicable independent approach based on the integration of tree-ring analysis and radiocarbon dating. Interrogating the subjective assumptions and stepwise logic transfers involved in ceramic-based dating, the authors demonstrate how to produce a more robust and better-defined basis for the analysis of the ancient Mediterranean shipwreck record.

Taking a geopolitical perspective centred in the Argentinian Andes, the authors propose a hermeneutical view of dialogical archaeology. The application of this theoretical and methodological approach to the example of the archaeological site of Huayatayoc (Puna de Jujuy, Argentina) enables an interpretation of the site as a complex woven fabric of diachronic local and scientific practices and narratives. The authors’ work at Huayatayoc provides an example of the potential of this approach for the development of a critical Latin American archaeology, which seeks to acknowledge the multiple interests and narratives of researchers and local communities in dialogue.

How often, and in what contexts, have archaeologists discussed racism over the last four decades? Do societal events lead to sustained discussions of racism among the academic community? Here, the authors seek to answer these questions by applying computational text analysis methods to 68176 abstracts from 41 meetings of the Society for American Archaeology. Discussions of racism are found to be rare—usually a passing mention in the context of broader social issues. Historical archaeologists have addressed racism more frequently than other archaeologists. The results form a baseline against which the discipline's engagement with racism as a research theme and with anti-racist strategies might be tracked.

Fortification walls and other buildings discovered during renewed excavations at Tel Erani (Tell esh-Sheikh el-Areyni) shed new light on the beginnings of urbanisation in the Southern Levant during the second half of the fourth millennium BC.

Large, conglomerate caves in north-eastern Iberia have been significant places since the Neolithic through to historical times; however, their significance during the Palaeolithic has barely been explored. This project is the first systematic study of the use of these iconic geological landmarks among Pleistocene hunter-gatherers.

Humans have engineered their environments throughout the Holocene, especially in the construction of hydraulic infrastructure. In many regions, however, this infrastructure is difficult to date, including the vestiges of water-management systems in the Andean highlands. Focusing on silt reservoirs in the upper Ica drainage, Peru, the authors use cores and radiocarbon dates to demonstrate the pre-Hispanic construction of walls to enhance and expand wetlands for camelid pasture. Interventions dated to the Inca period (AD 1400–1532) indicate an intensification of investment in hydraulic infrastructure to expand production capacity in support of the state. The results are discussed in the context of the hydraulic strategies of other states and empires.

We explore the long-term environmental and human history of a small outer coast archipelago on the Northwest Coast in western Canada. Using relative sea-level change, we reconstruct ancient landscapes to design archaeological surveys that document a rich archaeological record spanning at least 11 000 years and demonstrate the cultural centrality of this geographically marginal landscape.

The Çanakkale-Balıkesir Coastline Palaeolithic Survey Project covers the Çanakkale and Balıkesir coastlines of the Aegean. It aims to reveal Palaeolithic assemblages and their connection to the surrounding islands—primarily Lesbos. In 2021, four important findspots were detected on the Çanakkale coastline, and more than 500 lithics were uncovered, exhibiting the characteristics of large cutting tools, as well as pebble and prepared core technologies. These tools attest to the presence of hominins along the Çanakkale coastline during the Lower Palaeolithic.

Research on prehistoric mainland Southeast Asia is dominated by mortuary contexts, leaving processes such as the transition to sedentism relatively understudied. Recent excavations in southern Vietnam, however, have recovered new evidence for settlement. The authors report on investigations at the neolithic site of Loc Giang (3980–3270 cal BP) in southern Vietnam, where excavation revealed a vertical sequence of more than 30 surfaces. Microarchaeological analyses indicate that these features are carefully prepared lime mortar floors; the lime was probably produced from burnt shell. The floors date to between 3510 and 3150 cal BP, providing the earliest-known evidence for the use of lime mortar, and for durable settlement construction, in this region.

Beginning in the Middle Palaeolithic, human populations penetrated areas of Central Asia that are today characterised by extremely arid conditions. Mongolia's Gobi Desert comprises one such region. Tsagaan Agui Cave presents an example of the later Pleistocene occupation of this area, containing stratified evidence of diachronic, intense human and animal occupation.

The port-city of Adulis in modern Eritrea was a key node on the Red Sea linking the Kingdom of Aksum to the Mediterranean, the Middle East and the Indian Ocean. Recent excavations at Adulis have reinvestigated two early Christian churches. New radiocarbon analysis dates both structures to the sixth and early seventh centuries AD, with multiple phases of architectural development reflecting changing use and liturgy. The author uses evidence for both continuity and change in architectural materials, construction styles and sacred practices to assess religious transition at Adulis, and across the Aksumite Kingdom more broadly. Moving beyond an archaeology of conversion, the article reinforces recent work on cosmopolitanism in the Horn of Africa.

Colonised societies often continue traditional practices in private contexts whilst adopting new forms of ritual in public. Excavations at the Mam centre of Chiantla Viejo in highland Guatemala, however, reveal a more complex picture. Combining archaeological evidence with early colonial documents, the author identifies a revival of Indigenous Maya religion following the Spanish conquest (AD 1525–1550). Despite appearing in colonial records as Christian converts, the Maya directed a sequence of destruction, reconstruction and remodelling of the monumental core of Chiantla Viejo to evoke the landscape of their ancestral settlement of Zaculeu. The results emphasise the importance of public spaces for the persistence of Indigenous religion in early colonial settings.

In a sculpted frieze on a lintel of the so-called Temple of Allat at Hatra (second century AD), two rows of sitting camels converge towards a possible royal portrait. The two lead animals were previously interpreted as Bactrian camels. We reconsider this interpretation in light of recent information on ancient and contemporary practices of hybridisation between Camelus bactrianus and Camelus dromedarius.

Archaeological fieldwork at the fortified site of Kuiyukexiehai'er (Koyuk Shahri) in the Xinjiang Uygur Autonomous Region of north-western China yields the earliest known evidence for urban occupation in the Tarim Basin, providing new insights into early urbanism and agro-pastoral subsistence practices in the region during the first millennium BC.

Nearly 500 kite-like structures have recently been discovered in the western Sahara using high resolution satellite images. Although four distinct types with different morphologies have been distinguished, their characteristics, topographical location and orientation in the landscape indicate that they are all most likely hunting traps.

New research at the Doroshivtsi site in Ukraine has provided data that allow fresh insights into a well-known and important Gravettian site in the Middle Dniester Valley.

Found only in a restricted area of north-west Australia, the Australian boab (Adansonia gregorii) is recognisable by its massive, bottle-shaped trunk, and is an economically important species for Indigenous Australians, with the pith, seeds and young roots all eaten. Many of these trees are also culturally significant and are sometimes carved with images and symbols. The authors discuss the history of research into carved boabs in Australia, and present a recent survey to locate and record these trees in the remote Tanami Desert. Their results provide insight into the archaeological and anthropological significance of dendroglyphs in this region and add to a growing corpus of information on culturally modified trees globally.
