This paper compares various wood pretreatment methods for highly degraded, and problematic fossil wood extracted from the opencast Szczerców site of the Bełchatów Lignite Mine in Central Poland. The study evaluates the pretreatment methods using both large samples (55–255 g, referred to as series A) and small samples (36–150 mg, referred to as series B). Additionally, all preparation methods were applied to medium-sized samples (approximately 3 g, referred to as series C) with solvent washes in the Soxhlet apparatus. Radiocarbon dating was conducted using the LSC technique (subseries A1) and the AMS technique (subseries A2, series B, and C). The effectiveness and utility of each pretreatment protocol were compared based on 14C measurements and FTIR analysis. Through the conducted research and a multi-criteria analysis, the most effective method for preparing old fossil wood was identified. Our experience indicates that an extended, multistage preparation of highly degraded fossil wood samples, with a 14C concentration near the detection limit of the radiocarbon method, may result in a significant increase in 14C content.

Este trabajo presenta una aproximación comparativa a las lógicas visuales de figurinas, vasijas efigie, sonajeras y colgantes, en su mayoría de cerámica, que proliferaron en el septentrión venezolano a partir de aproximadamente el primer milenio aC hasta la llegada de los europeos al continente americano. Se comparan transversalmente diversas iconografías halladas en el noroccidente del país, la región andina, los llanos, la región norcentral y el bajo Orinoco, partiendo de los elementos compositivos que articulan las figuras. Estas se componen de una base antropomorfa (combinación de tronco, piernas, brazos, cabeza, etcétera), que también puede conjugarse con elementos zoomorfos, los cuales podrían hacer referencia a entidades no-humanas o a procesos de transformación chamánica. Nos enfocaremos en la asociación de algunos elementos compositivos con la denotación sexual de las iconografías. Estas comparaciones nos permiten reconocer persistencias y concomitancias a través de grandes lapsos temporales y distancias geográficas, y contribuir a desmontar algunas preconcepciones que consideramos restrictivas respecto de los significados asociados a manifestaciones visuales femeninas.

The increase in biobased material usage requires the methods of verification to investigate the actual content of biocarbon in such materials, including liquid fuels. The determination of biocarbon in liquid samples using 14C required adaptation of existing sample preparation methods. In this study, both accelerator mass spectrometry (AMS) and liquid scintillation counting (LSC) methods were used to determine the content of 14C in six different liquid fuel blends produced from purely bio-based hydrotreated vegetable oil (HVO) and a 14C-free petrodiesel sample (ON/UF-BC). The results obtained for pure petrodiesel provide background values. The results indicate a good agreement between LSC and AMS, and a linear correlation between the 14C measurement results for blended samples and HVO content affirmed the reproducibility between the two methods. The repeatability of AMS results was tested on 10 aliquots of one of the blends, and the results were deemed reproducible.

In this article, the author explores the cooperative aspects of mound construction in Late Iron Age Scandinavia. Arguing against the outdated but widely held view that only centralized rule could organize monument construction, he investigates how participation in mound construction affected the people of Sør-Fron in south-eastern Norway. He contends, first, that repeated participation in mound construction helped create a sense of belonging and shared identity, which was maintained through centuries of major environmental and political turmoil. Second, mound construction was part of an active and conscious strategy to limit aggrandizement and prevent centralization and concentration of power. Rejection of Christianity arguably worked in similar ways. The author concludes with considerations of approaches to Iron Age monuments, emphasizing the importance of consensus and community-building and the role of communal opposition to centralized rule.

We present an annual-resolution, millennium-long tree-ring chronology for northern Japan. The chronology is based on 5309 measurements of tree-ring δ18O from 37 samples of Hiba arbor-vitae (Thujopsis dolabrata var. hondae). Although the exact geographical origin of 27 of the samples is unknown because they were extracted from excavated archaeological material, pattern matching of the tree-ring δ18O variations was robust among all 37 samples. The floating chronology constructed using all samples was cross-dated against a previously published δ18O chronology from central Japan, yielding a correlation coefficient of 0.26 (t = 9.0; p < 0.01), resulting in a temporal coverage of 417–1595 CE (i.e., 1179 yrs). The global 14C spike event at 774–775 CE was clearly recorded in the annual 14C data, which provides independent support for the dating of tree rings using oxygen isotopes. Furthermore, this δ18O chronology from northern Japan was used to successfully cross-date a wood sample buried during the “Millennium Eruption” of Baitoushan, which is located on the border between China and North Korea.

The Palaeolith collection of the antiquarian Dr Tom Armstrong Bowes was the founding component of Herne Bay’s first museum and became one of the larger and more significant collections in the British Palaeolithic record. Its value to debates on the British Palaeolithic, however, has been limited by a stark lack of contextual data. Previously unstudied museum archives have now begun to unlock the lost provenance of this large collection so that it once again can contribute to long-standing regional questions on Acheulean typologies.

Although the practice of human sacrifice in the British Iron Age is mentioned by multiple authors, both ancient and modern, physical proof of such activity in the archaeological record is comparatively rare. At Winterborne Kingston, in Dorset, the skeletal remains of a young adult female found face down near the base of a cylindrical storage pit provides clear evidence of violent death in the later Iron Age. Analysis of the skeleton suggests an individual who led a hard-working life and who, having suffered an act of violence a few weeks before death, was killed, possibly with her hands tied, by a blade incision to the neck. Placement of the body further suggests that killing was enacted within the pit, execution as spectacle forming the final act in a larger ceremony involving the creation of an animal bone stack or platform.

The impetus for this study was a review of the Society for American Archaeology (SAA) 86th Annual Meeting program in 2021. Finding that no single poster or presentation referenced looting or antiquities trafficking despite these issues being ethical considerations that all SAA members are expected to recognize, we sought to investigate whether this was an irregularity – perhaps due to the virtual format of the meeting – or whether it was more common than not. For a broader understanding of if, how, and where these topics are discussed by archaeologists outside of the SAA, we expanded the investigation and studied the archives of 14 other archaeological and anthropological conferences. The results of the study show that despite there being an overall increase in mentioning looting and antiquities trafficking at conferences, it remains a niche and infrequently discussed topic.1

This paper discusses some of the major ethical issues that arise in connection with the widespread holding of cultural heritage by private collectors. If, as many people believe, and UNESCO has affirmed, cultural heritage is, in some morally significant sense, everyone’s heritage, then the private acquisition of cultural heritage, although widely permitted in law, raises some significant ethical questions. I discuss the nature of the tension between public heritage and private ownership of heritage items and the possibility that more might be done by law to regulate the activities of private collectors before arguing the merits of a shift in the mindset of collectors from thinking of themselves as the unfettered owners of the heritage they acquire towards conceiving themselves primarily as stewards who protect and preserve that heritage on behalf of the wider community. There follows a detailed examination of practical ways in which collectors can discharge their stewardship role to the best effect, emphasizing, in particular, the fresh opportunities for doing so afforded to collectors by the new digital environment.

The Maya used dress to help them structure social interaction. Taking a behavioral chain and practice approach, I define dress elements of male courtiers and how they were combined into outfits during the daily practices of dressing and attending court. I identify two groups of headgear, Standard and Special, among courtiers on vases showing historical interaction among humans. Each vase is considered commemorative and must communicate to an audience. I identified six Standard hat types that were widespread in the Maya Lowlands. The distribution implies a basic set of recognizable roles that provided the political-religious structure of the typical Maya court, perhaps as early as the Late Preclassic period. Four of the hat types are connected to glyphic titles. Each titleholder's position in the vase's visual space implies a hierarchy of roles. The results support my hypothesis that dress does identify social roles in the Maya court.

A battle-axe made of picrite from the Cwm Mawr rock source, near Hyssington, Powys, UK, was discovered during the archaeological excavation of two Early Bronze Age barrows at Church Lawton, near Alsager in Cheshire, UK, in 1982–3. It had been subjected to intense heat and then placed in a pit, next to the cremated remains of an adult, possibly a female. The heating has radically altered the appearance of the axe. Originally very smooth and dark grey-green, it now has a more granular and dusty feel, together with a mottled orange-reddish appearance. The Church Lawton battle-axe is particularly notable as it is among a small number of such artefacts in Britain to have been recovered from a barrow excavation conducted according to modern standards, as well as being directly associated with an interment dated by radiocarbon: 1893–1740 cal bc (3490 ± 29 bp). It is also the first implement from the Cwm Mawr rock source to be dated in this way. An initial examination of the battle-axe was conducted in the 1980s. A more exacting analysis of the object has now been undertaken, focusing on its petrology in relation to the rock source, its manufacture and use, and its heating. The new examination included the use of stereoscopic and metallographic microscopes. This paper details the new work and provides an enhanced understanding of the implement’s history and significance, emphasising the likely connections between the Early Bronze Age community at Church Lawton and others in the wider region.

The Wichita and Affiliated Tribes have a long history of occupation in what is now known as Oklahoma. This includes evidence of habitations along Camp Creek and Sugar Creek near Anadarko in Caddo County. Here Wichita peoples camped, built grass houses and arbors, and held social gatherings leading up to and following the passing of the General Allotment Act in 1887. After allotment, communal camp and dance grounds were especially important focal points for community building. These places, such as the ichaskhah camp and dance ground discussed in this article, are critical to understanding the multigenerational connections between ancestral and living Wichita peoples. This history is also important to the community today. However, archaeological research of the Allotment period is exceptionally rare in this region. By using collaborative and Indigenous archaeological methodologies, this work documents the complexities of these places, challenging traditional assumptions of allotment-era cultural loss and assimilation.
