A database of ca. 970 radiocarbon dates on bones, teeth, and tusks of the woolly mammoth (Mammuthus primigenius Blum.) from Siberia was created in order to understand the spatiotemporal distribution of this species over the last 50,000 14C years (BP). Mammoths populated all parts of Siberia until ca. 12,000 BP. After that, a few refugia exited south of ca. 60°N at ca. 10,600–12,000 BP, and in the northern part of mainland Siberia mammoths survived until ca. 9700 BP. At ca. 9500–3700 BP, they existed only in today’s insular regions such as the New Siberian Islands and Wrangel Island in the High Arctic. The relationship between the dynamics of mammoth populations and climatic fluctuations is complicated. In the warmer intervals (interstadials), the number of mammoths in Siberia was generally slightly larger than in the colder times (stadials); however, the difference is often not significant. The connection between the dynamics of mammoth populations and climatic fluctuations in Siberia is therefore complicated and non-linear.

We report the results of radiocarbon dating performed at the ETH laboratory on soft tissue of the mummified body found in September 1991 on the Hauslabjoch in the Ötztaler Alps (near the Similaun Mountain), South Tyrol. Over the past three decades, additional analyses of the sample, which had been stored frozen in a glass jar, have improved the precision of the first published radiocarbon ages. The frozen jar and the story of a mummified body found in the Alps fascinated visitors to the laboratory, mostly primary and high-school students. As part of educational projects, 11 samples were prepared and analyzed, yielding a combined radiocarbon age of 4525 ± 7 BP. This agreement with 4550 ± 27 BP, i.e., the very first results by Bonani et al. (1994), highlights the quality of the analysis performed decades ago. The combined age of all the 14C ages measured at the ETH laboratory is 4527 ± 7 BP.

This paper develops a framework based on Bourdieusian principles to analyse the formation of a trans-cultural colonial community in Sinope (Türkiye) by highlighting spaces where social competition was performed. A case study based on the Greek colonial settlement of Sinope in the Black Sea highlights five gathering spaces: the city wall, cemeteries, the city plan, domestic architecture, and the marginal lands beyond the agricultural catchment. This framework is intended to be equally useful for analysing the sharing of cultural elements across Greek and non-Greek settlements in a complex colonial world. Focusing on the changing dynamics of social, cultural and economic capital in community formation, the ‘ethnicity’ of cultural forms is downplayed and the social stimulus of cross-cultural contact illuminated. The ultimate goal is to develop a framework that applies to a broad range of trans-cultural situations including ancient and modern colonialism, pilgrimage and refugeeism.

We present a short database of the mole fraction of CO2 and 14CO2 in atmospheric air samples from an urban area in Gliwice, Silesia, Poland. The research covered a period from August 2023 to July 2024. A new laboratory air sampler stand was established to monitor carbon dioxide levels in Gliwice, giving the possibility to determine CO2 levels in the air using appropriate instruments to collect the air samples, extract CO2 from them, and thus measure carbon isotopes ratio 14C/12C. The analysis of the mole fraction of CO2 was determined using a low-cost system (CARBOCAP GMP343), while the carbon isotopes concentration was measured using MICADAS. The 14C in the air samples varied randomly from –55 to –24‰, while the monthly mole fraction of CO2 varied from 428 to 470 ppm. It has been also observed also that CO2 concentration is linked with the planetary boundary layer. The fraction of fossil of total CO2 has been estimated at the level of 2.5% during the investigated period of time. Another aim of this study was to investigate pine needles as 14C archives in a contemporary environment. The examination of the needles was based on the analysis of the similarities and differences in radiocarbon concentrations in pine needles of various ages collected in the middle of consecutive seasons, with 3 months resolution in Gliwice. The concentration of 14C in the needles was determined using a liquid scintillation counter. The mean F14C from all the samples was 99.80(70) pMC.

Despite improvement over the past few decades, particularly for white, cisgender women, intersectional gender-based inequality remains prominent within anthropological archaeology and beyond. Building on critiques of the leaky pipeline metaphor laid out in the introduction to this themed issue, and drawing on Black, Indigenous, and Posthumanist Feminisms, we advocate for a metaphorical shift focused on care, inclusivity, and diversity—that of a garden. The garden metaphor provides a way to express and explore the complex and intertwined ways disciplinary norms, institutions, and individuals structure and shape experiences in archaeology. After reviewing the garden metaphor and summarizing previous suggestions for improving equity in archaeology, we present recommendations for actionable steps at disciplinary, institutional, supervisory, and individual levels. Drawing on insights from the articles in the issue, as well as existing literature within and beyond archaeology, we argue that a greater emphasis on care, and its integration into the value structure of archaeology, would create a more inclusive discipline.

The date of the Thera eruption has been a subject of intense debate since the mid-20th century. In recent years, the disagreements have escalated with the introduction of IntCal20. The increased number of annual measurements around the time period of the eruption has highlighted potential fluctuations in the atmospheric radiocarbon record, shedding new light on the date of the disastrous event. The Centre for Isotope Research in Groningen has already contributed data from this time period to IntCal20, and here, we report a new set of annual data of approximately 90 radiocarbon measurements between 1660 and 1507 BCE. We investigate the potential anomalies in the calibration curve and compare our dataset with those from other leading laboratories. Although we do not find compelling evidence of any rapid increases in radiocarbon production during this period, the results do point to the presence of minor differences between datasets which could be species, region or laboratory pretreatment related. By quantifying such offsets, we assess their impact on chronological models related to the eruption of Thera.
