Iraya Volcano, situated at the northern tip of Batan Island in the Batanes group, marks the northernmost extent of the Philippine archipelago. Aside from the presence of accessible tephra deposits, the numerous archaeological sites on the island provide key insight into tephrochronology and volcanic hazard assessment. This paper presents stratigraphy and 21 radiocarbon ages of Holocene tephra layers distributed on the island. The eruption ages of the Holocene tephra are approximately 12.4 cal ka BP for Rolling Hills at the bottom, 4.5–4.9 cal ka BP for San Antonio, 2.1–2.5 cal ka BP for Mahatao, 1.6 cal ka BP for Basco, and 1.2–1.6 cal ka BP for Boulder Beach, with most of the tephra concentrated in the latter half of the Holocene. Artifacts excavated from Reydante Cabizon Property Site, San Antonio, Basco can be thought to date to around 4 to 2 cal ka BP, which is consistent with tephrochronology.

This work aims to clarify the absolute chronology of the construction phases of the St. Peter and Paul Rotunda at Budeč, focusing on the erection of the rotunda and the tower. Fifteen mortar samples were taken from various structural parts, two of which also contained remnants of charcoal. The mortar samples were mechanically treated to extract a purified calcitic binder that was dated by radiocarbon analysis. The effectiveness of the sample pretreatment methodology was assessed by means of cathodoluminescence microscopy. Thin sections of mortars were characterized by polarized light microscopy. The petrographic characterization allowed for the samples to be grouped according to their binder, aggregate, and structure. This was compared with the evaluation of the calibrated dates, expected chronology known from legends, as well as with formal and stylistic analyses of the structure. The radiocarbon dating distinguished the different construction phases well, and the accuracy and reliability of the dating is discussed. The presence of silts and clays probably led to geogenic carbon contamination of the samples from the foundations, as the obtained dates are older than expected. These dating results were thus regarded as inconclusive. However, the samples from the vaulted dome of the rotunda did not show any anomalies, and the calibrated date period obtained was regarded as relevant and thus successfully dated. The dating based on the legends also fits the determined interval.

Las antiguas élites mayas jugaban a la pelota. Esta acción y las actividades asociadas se enfatizan para complementar las interpretaciones simbólicas de estudios anteriores. Basándose en la teoría de conjuntos, se discute cómo las interacciones recurrentes y causales institucionalizaron el juego de pelota. Los análisis multiescalares y multidimensionales permiten estudiar las relaciones parasociales, asimétricas y co-constitutivas entre los jugadores, el público y la cancha. En el este de las tierras bajas mayas, se encuentra el centro de Tzikin Tzakan, donde se documentaron dos canchas de juego de pelota. Debajo de la parte de las superficies originales de la cancha oeste, se encontraron varias capas de lascas de pedernal. Su presencia infiere la furia y el dolor que ocurría durante el juego de pelota. Los nobles jugaban sabiendo que sufrirían y hasta podrían fallecer. Se documentó un basurero que probablemente refleja las fiestas asociadas al juego y que apunta al rol del público en crear y gozar un espectáculo. Comparadas con 50 canchas cercanas, las canchas de juego de pelota de Tzikin Tzakan destacan por su orientación, su forma y sus dimensiones. Sus características regionalmente únicas y localmente compartidas ejemplifican el juego de pelota como una totalidad emergente.

This study presents the integrated results of stable carbon (δ13C) and nitrogen (δ15N) isotope and aDNA analyses, conducted to examine dietary and mobility practices in two mid- to late Byzantine communities in western Anatolia: the coastal cosmopolitan site of Kadıkalesi Anaia and the rural inland settlement of Barcın Höyük. Isotopic data from thirty-eight individuals indicate that both populations primarily consumed terrestrial C₃-based resources. At Kadıkalesi, δ15N values show greater variability, suggesting more differentiated access to animal protein sources, whereas the rural community at Barcın Höyük exhibits isotopic homogeneity, consistent with more uniform dietary practices and an equitable access to food. Kadıkalesi also shows intra-site dietary variation by age and sex, while Barcın is again more homogeneous. At Barcın, aDNA results indicate a predominant local genetic continuity, suggesting a stable population; a single instance of external ancestry is attested by a male individual with affinities to western populations, particularly from eastern Europe, in line with historical military resettlement patterns (stratiotika ktemata). By integrating isotopic and genomic evidence, this study demonstrates how ancestry and mobility shaped dietary habits, offering insights into the interplay of urbanism, mobility, and social organization in the Byzantine period.

Archaeologists engage with the public in various ways and, with the popularity of social media, are learning to adapt to the fast-paced nature of content creation. Posting online provides opportunities for archaeologists to engage with the public at any time and is a tool that can be used to share our knowledge quickly and broadly. Archaeological social media content can use many different approaches, but short-form video content is particularly effective. Many of these methods have similar goals: to educate the public and entertain. This digital review introduces different aspects of social media like the attention economy, online echo chambers, and the public’s reaction to posts about archaeology.

This article addresses the proposition that the lower Lahontan drainage basin (LLDB) is “unique” within the Intermountain West in terms of the use of caves and rockshelters as burial locations, and that such burials are “rare” elsewhere (Thomas et al. 2025). We compare archaeologically known cave burials in the Bonneville basin (BB), ranging in age from approximately 10,700 to approximately 1000 cal BP, to those in the LLDB. There are 18 such sites in the BB and an additional five in the upper Lahontan basin within the foraging range of late Holocene BB farmer-foragers. Although this number is roughly half of that in the LLDB, such sites are not “rare” or even uncommon in the BB. The difference in numbers may be attributed more to differences in population sizes in the two basins than to differences in burial practices. After about 5000 cal BP, many caves and rockshelters containing burials in the LLDB were occupied residentially, diurnally, or while storing and retrieving cached material. Given that Thomas and colleagues (2025:246) indicate the Northern Paiute tended to avoid such caves, it is likely that it was the ancestors of other groups who lived in them. Ethnographic and archaeological evidence suggests that at least some of these caves were occupied by the ancestral Washoe, whose historic territory extended into the LLDB, and possibly by related tribes who now reside exclusively in California.

This paper proposes an ecological framework for understanding medieval mining towns as dynamic socio-ecological systems shaped by flows of matter, energy, capital and information. Drawing on concepts from human and political ecology, it examines how mining, technology and power structures interacted to produce feedback loops and tipping points that transformed both society and the environment. A case study of Kutná Hora (Czechia) illustrates these mechanisms, showing how the discovery of silver triggered cycles of population growth, technological innovation and capital accumulation, whilst also causing deforestation, pollution and social stratification. The study highlights how medieval mining towns functioned as adaptive, self-organizing systems embedded in global economic networks, revealing early forms of extractive capitalism and environmental change. This ecological perspective offers a heuristic model for analysing historical urban environments and their long-term sustainability, bridging archaeology, history and environmental science.

Estimates of marine reservoir corrections (ΔR) in the southeastern Arabian Sea region are limited. To better constrain the region’s marine reservoir corrections, additional pre-bomb radiocarbon records are needed. In this context, a coral core from the Lakshadweep archipelago in the southeastern Arabian Sea has been analyzed to measure its radiocarbon content. Pre-bomb radiocarbon values from the coral record are used to estimate the marine reservoir correction value of the region. The mean ΔR value of the Lakshadweep region is calculated to be –128 ± 130 yr. The comparison of available ΔR values from the Arabian Sea region shows that the mean ΔR value of the eastern Arabian Sea is significantly lower than that of the northern and western Arabian Sea. The low ΔR values from the eastern Arabian Sea likely indicate the influence of relatively 14C-enriched Bay of Bengal water in the region.

This article examines Group G, a commoner household at the Classic-period Maya site of Chinikihá (a.d. 200–900), to explore how daily practices, household rituals, and architectural histories intersected within domestic space. Excavations revealed well-preserved architecture, including a patio, kitchen, and dwelling, with evidence of construction events, ritual offerings, and long-term maintenance. Soil chemical analyses identified signatures of food preparation, consumption, and maintenance activities through residues of phosphates, proteins, fatty acids, and carbohydrates, alongside charcoal and paleoethnobotanical remains. Combined with botanical evidence such as Guadua (bamboo) and pine (Pinus sp.), these results underscore the importance of kitchens, patios, and altars as spaces of production, memory, and ritual practice. Residues preserved in floors and surfaces provide intimate insights into daily activities while situating households within broader cultural and cosmological frameworks. By focusing on a non-ruling-elite domestic group, this research highlights the resilience of Indigenous technologies and practices and their enduring continuity into modern Maya communities, contributing to broader discussions on social organization, identity, and tradition in ancient Mesoamerica.
