Several decades ago, the National Park Service's Chaco Project revealed evidence for widespread ornament manufacture at small sites (small houses) in Chaco Canyon, New Mexico, as well as possible workshop-scale production at two of these locations. Given that consumption of finished jewelry items is clearly concentrated at large sites (great houses), it was suggested that lapidary production was part of a larger corporate political strategy, in which goods produced in surrounding small houses were used to sustain communal events related to construction activities and ritual performances at great houses. This article addresses a critical gap in this narrative—ornament production at great houses. Using Pueblo Bonito as a case study, I present the results of a systematic analysis of lapidary tools from the site and characterize the nature of on-site ornament manufacture. I find evidence that significant jewelry-making was occurring at Pueblo Bonito, at least on par with previously documented small-house jewelry workshops, and that a portion of this was embedded within elite households. These results require us to reconsider the role of ornament production in Chacoan political economy.

Several anthropological and historical studies based on comparative research show that there is no universal concept of ‘cleanliness’ or ‘hygiene’ common to all cultures in all historical periods. Ideas about what is considered clean, the means used to keep persons, objects and places clean, and the frequency or appropriate timing of cleaning actions differ between cultures, and even within a given culture. The latter implies that, sometimes, these differences depend on social position, mainly because this position allows or prevents certain cleansing practices. In addition, the concept of ‘cleanliness’ may sometimes be intertwined with the idea of ‘purity’, and thus be related to religious beliefs and practices. The present article examines the concept of ‘hygiene’ for the case of the Hittites, and aims to do so from an historical perspective by reflecting on modern vocabulary related to hygiene, investigating Hittite terminology related to cleanliness and analysing textual sources. Archaeological evidence will be examined alongside the textual sources to establish correlations regarding locations and objects used for hygienic practices. The objectives are to investigate who practiced cleanliness and when in Hittite culture, how and where these practices occurred, and what objects were used, as well as how the Hittites understood hygiene and whether perceptions and practices varied by social group.

This study is concerned with the evaluation of a recently discovered Aramaic inscription and other archaeological remains found at Rabat Fortress (in Tunceli, Türkiye). The Hellenistic period Aramaic funerary text was composed in memory of a local lord from Sophene’s local political elite, with connections to the Orontid dynasty. This is the first known local Aramaic inscription from Sophene. The Aramaic inscription introduced in this study provides significant new information about the Hellenistic-period context for rock-cut stepped tunnels and single-roomed rock-cut tombs known across eastern Anatolia. The Rabat Fortress site provides corroborating evidence for the dating of the stepped tunnels that exhibit the same rock-cutting techniques in the same region to the Hellenistic and later periods in the rocky landscape. The inscription is rendered in a unique Sophene adaptation of the Middle Aramaic script extant on a corner block inside the Fortress. Its funerary context in rocky landscape and the inscription’s script and content indicate that the local elite at Rabat Fortress used Aramaic, and the notion of Orontid lineage to connect with the kingdom of Sophene’s central authority, which positioned itself between Hellenistic and Iranian traditions.

The discovery of green-fractured mammoth bone in Owl Cave in the 1970s inspired the original investigators to focus primarily on the possible association between these remains and Folsom points recovered from the same stratum. With the Museum of Idaho's recent acquisition of the complete Owl Cave collection, we have gained a better understanding of the periglacial processes that appear to have displaced and mixed mammoth remains with a younger Folsom component. New efforts to date bison bone also recovered from the lowest levels of the cave have produced radiocarbon dates that fall within the accepted age range of Folsom technology. These results have prompted efforts to investigate the potential for an association between the lithic assemblage and bison, a scenario that is much more plausible given our current understanding of the Folsom archaeological record.

There is no consensus on who built the numerous stone structures that dot the archaeological landscape in the northeastern United States. Professional archaeologists traditionally have attributed them to colonial farmers, but increasing numbers of archaeologists have joined many nonprofessional groups and Native Americans in arguing for Indigenous origins. Better understanding of these structures can be obtained by determining how old they are. This article reviews nearly 60 luminescence ages, on both sediments and rocks, that have been obtained in recent years. Many of the derived ages fall in the sixteenth century, between initial European contact and substantial colonial settlement. A few ages are significantly older, suggesting that this technology has a deeper origin. The results warrant more research into these structures and rethinking their significance.

The practice of settling former soldiers in ‘colonies’ is well attested in Anatolia. The area of and around Pisidia received several such colonies during the Hellenistic and Roman periods, a phenomenon which must have had a significant demographic impact on the region. Building on previous research that has investigated the colonies of this region of the Hellenistic and early Roman periods, this paper collects the evidence for further settlements being planted on the various peripheries of Pisidia: first, in the territory of Apollonia, in the northern borderlands between Pisidia and Phrygia; second, on the Cillanaean Plain on the eastern fringes of Pisidia; and finally in Milyas, the territory on the southern boundaries between Pisidia and Lycia. It argues that significant groups of Lycian and Thracian ex-servicemen were settled in these areas, and suggests that this happened in a relatively short period of time between 36 BC and 25 BC, during the short reign of a local king, Amyntas. Sandwiched between the period of the Hellenistic poleis that preceded it, and the time of direct Roman rule that came after, the reign of Amyntas nonetheless left a lasting legacy on the landscape in the form of these new settlements.

This study delves into the comprehensive examination of an anta capital discovered during the 2008 excavations at the ancient site of Alabanda in Caria, now housed in the Aydın Archaeological Museum. Employing a typological and stylistic analysis, the research attributes the capital to the latter part of the fifth century BC, emphasising its intricate architectural ornamentation and sculptural details that reflect significant artistic and cultural developments of the period. The capital features elaborate ornament bands and mythological reliefs, including depictions of Bellerophon-Pegasus and Chimera, and a griffin attacking a horse, which are analysed for their iconographic and symbolic significance within the broader Anatolian and Mediterranean contexts. The study also explores the potential original architectural setting of the capital, suggesting its use in a monumental tomb, a hypothesis supported by its dimensions and decorative complexity. Furthermore, the article discusses the role of such imagery in asserting local identities and engaging with wider Hellenic cultural and political themes, particularly considering the complex interactions between local Carian traditions and the dominant Greek culture of the period. The findings not only contribute to our understanding of Carian art and architecture but also highlight the region’s active participation in the cultural dialogues of the Classical world.

The cause of megafauna extinction in South America remains clouded in controversy, since it took place at a time of intense climate change and almost at the same time as the initial human influx into the continent. In this paper, we aimed to assess the effects of climate change on open vegetation habitats and, consequently, on megafauna extinction in South America by using a species distribution model, fossil records, and paleoclimatic projections. In addition, we evaluated the effects of climatic variables on the distribution of suitable habitats across South America. Our results demonstrated alternating intervals of expansion and contraction of suitable areas for megafauna persistence, mainly in response to lower and higher precipitation, in the last 21 ka in all regions of South America. However, the amplitude of this oscillation was more significant in the Brazilian Northeast. In the Andean and Chaco–Pampas regions, greater precipitation stability resulted in greater stability in habitat suitability; therefore, for these regions, other factors must have predominated for the extinction of the megafauna. We therefore concluded that in the Andean and Chaco–Pampas regions, climate change was not solely responsible for the disappearance of megafauna, but in the Brazilian Northeast, it may have been decisive.

Lake sediment provides a valuable record of past environmental change. However, the controls on sedimentation in proglacial lakes and their relation to glacier retreat remain poorly understood. In this study we analyze glaciolacustrine sediment production and deposition in Canal de los Témpanos, Lago Argentino, Argentine Patagonia. We associate temporal changes in the sedimentologic and geochemical characteristics analyzed from Lago Argentino cores with Late Holocene fluctuations of the Perito Moreno and Ameghino glaciers. We show that the dominant sediment source at our study site switched from Ameghino to Perito Moreno Glacier after the recession of Ameghino Glacier and the formation of the marginal ice-contact lake into which it currently calves. Spectacular ice-dam rupture events generated by Perito Moreno Glacier redistribute large volumes of water through the lake system but do not leave a significant sedimentary signature. Our results demonstrate that a detailed analysis of sedimentologic, petrophysical, and geochemical changes in lake cores can provide insight into regional glacial dynamics and sedimentary processes even in complex systems with multiple competing glacial sources and that changing glacier geometries during retreat can provide insights into the provenience of the sediments.

Accelerator mass spectrometry (AMS) is a worldwide recognized method for radiocarbon (14C) dating. The advantageous aspects of this method include the variety of materials and the small sample size (1 mg of carbon) that can be measured. However, these pose several challenges in the laboratory, such as developing appropriate chemical pretreatment methods. In the summer of 2022, the Radiocarbon and Mass Spectrometry Laboratory in Gliwice, Poland, launched the MICADAS accelerator spectrometer. The report on background and reference materials measurement results for the period from September 2022 to July 2024 is presented in this publication. Quality assurance and quality control processes are extremely important to guarantee the high quality of the results obtained in the laboratory. Hence, our Radiocarbon and Mass Spectrometry Laboratory in Gliwice took part in the Glasgow International Radiocarbon Inter-Comparison (GIRI) program. The radiocarbon ages for wood, bone, humic acid, and barley mash samples were determined and compared with reported values. The resulting data confirmed that our Laboratory is capable of dating samples across a spectrum of materials and ages ranging from contemporary to the limits of the radiocarbon method, achieving precision on par with that of other laboratories.

In this paper we present new AMS radiocarbon dates from the Bronze Age cemetery of Tiszafüred-Majoroshalom excavated between 1961 and 1972. The cemetery provides crucial information on the cultural development and chronology of the Bronze Age Otomani-Füzesabony and the Tumulus cultures of Eastern Central Europe, in addition to the transition between the Middle and Late Bronze Age (approx. 1500 BC) in the Great Hungarian Plain.

Large datasets, combined with modeling techniques, provide a quantitative way to estimate when known archaeological sites will be impacted by climatological changes. With over 4,000 archaeological sites recorded on the coast of Georgia, USA, the state provides an ideal opportunity to compare methods. Here, we compare the popular passive “bathtub” modeling with the dynamic Sea Level Affecting Marshes Model (SLAMM) combined with the Marshes Equilibrium Model (MEM). The goal of this effort is to evaluate prior modeling and test the benefits of more detailed ecological modeling in assessing site loss. Our findings indicate that although rough counts of archaeological sites destroyed by sea-level rise (SLR) are similar in all approaches, using the latter two methods provides critical information needed in prioritizing site studies and documentation before irrevocable damages occur. Our results indicate that within the next 80 years, approximately 40% of Georgia's coastal sites will undergo a loss of archaeological context due to wetlands shifting from dry ecological zones to transitional marshlands or submerged estuaries and swamps.
