Research published in the last decade, which has provided data from both technological and morphometrical analyses of lithic points from southeastern and southern Brazil and Uruguay, suggests that there is much more cultural diversity among hunter-gatherers during the Early to Mid-Holocene than previously suggested by the Umbu Tradition model. Some of these studies have suggested new archaeological cultures and new definitions of lithic industries. In this article we present new data on another lithic assemblage that we associate with the Garivaldinense lithic industry and is found at the Pedro Fridolino Schmitz site. We also present, for the first time, the definition of two new types of lithic bifacial stemmed points. Our data suggest a low-density occupation of the site from the Middle to Late Holocene (8000–1000 BP) and some variability within the Garivaldinense industry throughout time and space.

This article presents a case of osteomyelitis variolosa from a skeleton excavated in the Western Cemetery at Cirencester (Corinium) in Britain, dated to the 3rd or 4th c. CE. This osteological condition is caused by the variola virus, the causative agent of smallpox, and is found in some individuals who have survived a childhood smallpox infection, the condition manifesting many years later. The significance of this discovery is that it indicates that smallpox had been introduced into the Roman world, and to Britain in particular, by the late 3rd or 4th c. CE. Rather than postulating a separate and unrecorded introduction of smallpox into the Roman empire, we suggest that this discovery strengthens the case for seeing the 2nd-c. Antonine Plague as an early form of smallpox.

This article reports from an interdisciplinary, archaeological and philosophical research project developing and using an analogue model in archaeological research. With prominent uses outside of archaeology, analogue models can offer a unique participatory perspective to prehistoric processes. As such the paper contributes to recent discussions in this journal and elsewhere on the role of games, play and gamification in archaeological research, teaching and cultural heritage. Our analogue model critically discusses cultural-evolution-based models of selected European Neolithic and Bronze Age models and develops a perspective based on the life history and the Capability Approaches. In times of climate and war stress, our model can offer a hopeful perspective of the human past, present and future without compromising on scientific insights.

On the upper reaches of the Tigris and Euphrates, archaeologists encounter evidence that challenges conventional understandings of early state formation as a transition from ‘small-scale, egalitarian’ to ‘large-scale, stratified’ societies. One such location is the Early Bronze Age cemetery of Başur Höyük, which presents evidence of grand funerary rituals—including ‘retainer burials’ and spectacular deposits of metallic wealth—in an otherwise small-scale, egalitarian setting. A further, puzzling feature of this cemetery is the preponderance of teenagers in the richest tombs. Here we describe the combined results of archaeological and anthropological analysis at Başur Höyük, including ancient DNA, and consider the challenges they pose to traditional accounts of early state formation.

Highly precise and reproducible radiocarbon (14C) measurements are regularly performed at the Heidelberg Institute for Environmental Physics, Heidelberg, Germany, in collaboration with the radiocarbon laboratory of the Curt-Engelhorn-Center Archaeometry in Mannheim, Germany. Here, we report an update of the technical details, focusing on the analysis of cold-water corals (CWC), and present an improved long-term blank value with a mean of (0.190 ± 0.064) pMC (n = 138) and excellent reproducibility of the IAEA-C2 standard with a mean of (41.15 ± 0.16) pMC (n = 75), consistent with its certified consensus value. Furthermore, 33 duplicates of the CWC 14C measurements agree within 2σ, 85% even within the 1σ range. This provides excellent conditions for accurate 14C measurements. As an application example, we present combined 230Th/U and 14C ages of a coral-bearing sediment core from the upper Mauritanian slope. The resulting ventilation age record confirms decreasing ventilation between 30 and 25 kyr BP, most likely reflecting a northward propagation of a water mass originating from the south. During the LGM, we confirm a previously hypothesized southward displacement of the Cap Verde Frontal Zone. With the onset of the deglaciation, our record documents again an advance of a southern-sourced water mass into the subtropical North Atlantic. During the Bølling-Allerød warm period, strong ventilation fluctuations possibly indicate temporal influence of southern-sourced water.

Earthworm biospheroids are a useful alternative to radiocarbon (14C) soil dating. In this study, we undertook a series of measurements to test the 14C dating potential/performance of recent earthworm biospheroid granules. A novel sample preparation protocol for 14C in biospheroids was developed and elaborated at Atomki (Institute for Nuclear Research) and tested on IAEA reference materials. 24 natural biospheroid samples were extracted from five different location/environment-eight topsoils (A-horizon soils). Bomb-peak-based, high-resolution 14C dating show very uniform 14C results at 105.6 ± 2.6 pMC (1σ) and none of the biospheroids are older than 30 yr. It also shows that no biospheroid with a 14C bomb-peak as high as that observed in the 1960s and 1990s were observed. The results confirmed that earthworms do indeed consume almost exclusively recent biogenic carbon, not other organic compounds or inorganic carbonates previously bound in the soil. The calendar age of their biospheroids were extremely close to the real (zero) age of the surface. Thus, no “reservoir effect” is seen for these macrofossils. We conclude that a biospheroid-based 14C age determination method may be suitable to measure the burial time as long as earthworm biospheroids can be found in the soil.

Integral to the fabric of human technology, knots have shaped survival strategies since their first invention. As the ties that bind, their evolution and diversity have afforded human cultural change and expression. This study examines knotting traditions over time and space. We analyse a sample of 338 knots from 86 ethnographically or archaeologically documented societies over 12 millennia. Utilizing a novel approach that combines knot theory with computational string matching, we show that knotted structures can be precisely represented and compared across cultures. This methodology reveals a staple set of knots that occur cross-culturally, and our analysis offers insights into their cultural transmission and the reasons behind their ubiquity. We discuss knots in the context of cultural evolution, illustrating how the ethnographic and archaeological records suggest considerable know-how in knot-tying across societies spanning from the deep past to contemporary times. The study also highlights the potential of this methodology to extend beyond knots, proposing its applicability to a broader range of string and fibre technologies.

This study explores the emergence and dispersal of grog-tempered pottery in south-eastern Europe, particularly southern Romania. During the second half of the sixth millennium bc, a dynamic zone emerged between the Danube and the Carpathians, facilitating the spread of innovations through multiple communication routes. Among these innovations, grog-tempered pottery began to appear around 5300/5000 bc and became prevalent during the fifth millennium. Despite being frequent, its origins, dispersal, and intensity remain poorly understood. This article aims to trace and explain the emergence and distribution of grog-tempered pottery in southern Romania. By integrating data from existing literature with new results from macroscopic and archaeometric analyses of twelve pottery assemblages from Middle Neolithic, Early, and Middle Chalcolithic sites, the author seeks to provide insights into the significance of the first grog-tempered pottery in a south-eastern European context.

Radiocarbon (14C) measurements play important roles in dating and tracing applications where the isotopic concentration can differ from 0.1 to 106 pMC (percent modern carbon). A liquid scintillation counter cannot provide enough sensitivity when dealing with low-concentration samples of limited amounts over a reasonable time period. Accelerator mass spectroscopy (AMS) measures low-concentrations well but must first do dilution for high-concentration samples, and suffers from high instrument and maintenance costs. Saturated absorption CAvity Ring-down spectroscopy (SCAR) has now been developed into a practical technique with performances close to AMS but at much lower costs. The dynamic range covers 1–105 pMC, and the measurement uncertainties in the range of 0.4–1 pMC can be achieved within 0.5–2.5 hr of operation time. SCAR measures CO2 gases directly without graphitization in sample preparation. The typical sample consumption is ∼1 mg of carbon mass and the time for sample preparation can be as short as 15 min. Applications of SCAR to Suess-effect evaluation, biogenic-component analysis, ancient- and modern-sample dating, food-fraud detection and medicine-metabolism study have all been demonstrated by employing a close-to-automatic sample preparation system.

Ever since the first discovery of urn burials in eastern Serbia during the 1980s, their dating has been uncertain and based on distant analogies and typological parallels. In this paper, we present radiocarbon dates from five urn cemeteries and three associated settlement sites, showing that the initial dating (Late Bronze Age; 14th–11th BCE) is highly questionable. Instead, radiocarbon dating and modeling presented here connect the urn cemeteries—characterized by a specific grave architecture and associated with settlements that display evidence of copper production—to a period between the 20th and 16th centuries BC. The fact that many of our dates come from cremated bones requires a discussion with regard to the circumstances of carbon exchange during cremation. The absolute dates thus far available for most urn cemeteries from the neighboring regions of the Balkans are all markedly younger (15th–11th century BC) than the data presented here and fall in the frame of the overall expansion of cremation in Europe during the Urnfield period. The new absolute dates from eastern Serbia provide a possibility to change our understanding of the Bronze Age dynamics of the 2nd millennium in the broader area of southeastern Europe and indicate a much earlier acceptance of cremation among certain groups than previously thought.
