The Gruta da Aroeira (Torres Novas, Portugal), with evidence of human occupancy dating back ∼ 400,000 years, is one of very few Middle Pleistocene cave sites to provide a fossil hominin cranium in association with Acheulean bifaces and the by-products of fire usage. Zooarchaeological, taphonomic and tooth-wear analyses suggest that the accumulation of the faunal remains and their modification are anthropogenic. Large game constituted the basis of subsistence, with equids and cervids being preferentially targeted. Woodland and open landscapes formed the ecosystems supporting the populations of the mammals that were preyed upon by the inhabitants of the site. Most of the animal carcasses were carried to, and fully butchered at the site, which was used as a residential base camp. The features of the Aroeira faunal assemblage foreshadow the subsistence strategies developed by the hunter-gatherers of the Middle and the Upper Palaeolithic and testify to their very ancient roots.

The origin and process of the domestication of wild animals have long fascinated scientists. However, there are no reliable methods to distinguish between tamed and wild animals. Here, we present a new method to identify tamed and wild juvenile brown bears (Ursus arctos) using retrospective isotope analysis of the femur. We used femurs from the nine bear cubs and the tibia from one domesticated dog excavated from the Nijibetsu Shuwan Kumaokuriba site, Hokkaido Islands, Japan (late 19th century–1939 AD). These bears were potentially tamed by indigenous Ainu people, and the domesticated dog was used as a reference of a tamed animal. We subdivided these bones into 10 sections along the growing axis, extracted collagen and measured the stable nitrogen isotope ratios (δ¹⁵N). The bone sections of the domesticated dog had constant δ¹⁵N values that were as high as that of salmon, suggesting that tamed animals exclusively consumed a marine diet fed to them by the Ainu. Notably, two of nine brown bear cubs showed a temporal elevation of δ¹⁵N to the similar isotope ratios of the dog tibia, which is unlikely to occur in the wild condition, strongly suggesting that they were tamed and fed by the Ainu people.

Accessory vessels, including platters, dishes, beakers, flagons, jars, and amphorae, are a common feature of Romano-British burials, raising questions as to their provenance; for example, were such vessels recycled from the domestic sphere or made specially for funerary purposes? Furthermore, uncertainty surrounds their purpose: did they contain foods for the deceased, possibly for their final journey to the underworld? Interestingly, organic residue analysis of vessels from Baginton, a site adjacent to The Lunt fort, Coventry, an early (mid to late first century) Roman military cremation cemetery did not yield evidence for food offerings and may have reflected the use of seconds or damaged vessels in burials, perhaps to provide a symbolic meal. In contrast, here we provide, for the first time, direct chemical and isotopic evidence for ‘meals for the dead’, comprising mainly dairy products, often mixed with leafy plants, extracted from somewhat unusual accessory vessels found in a small, enclosed inhumation cemetery, perhaps associated with a family group, which dates to the late (third to late fourth century, or early fifth century A.D) in urban Canterbury. Thus, we can confirm that accessory vessels found in later Romano-British burials were, in this instance, used in the laying out of funerary meals, presumably to nourish the soul on the journey to the underworld. These preliminary insights on vessel use and burial practices across the span of the Roman occupation of Britain thus provide a strong hint at the diversity of Roman burial practices.

Despite the presence of a theoretical model describing the settlement patterns of Palaeolithic sites in Northwestern Iberia, it has not yet been empirically tested using statistical analysis. This study explores the settlement patterns of the Palaeolithic period in Northwestern Iberia within two regions that share similar chronology and research traditions: the Northern and Central Mountain ranges of Northwestern Iberia. Employing Geographic Information Systems (GIS) and spatial statistics, the methodology has provided robust empirical support for several aspects of the theoretical model. The study rigorously tested the theoretical model proposed in the existing literature using statistical analysis and a comprehensive dataset of 50 variables. The findings highlight significant regional distinctions in the settlement patterns of Palaeolithic sites within both areas of Northwestern Iberia. This research not only confirms certain hypotheses related to Palaeolithic site locations but also underscores the need for further examination and refinement of others, particularly considering the notable regional variations.

A group of a well-known polychrome glazed ceramic, widespread in the western Mediterranean in the eleventh and first half of the twelfth centuries, has been analysed for the first time using Optical Microscopy (OM) and a Field Emission Scanning Electron Microscopy (FE-SEM) with Energy-Dispersive X-ray Spectroscopy (EDS), in order to shed some light on the materials, production technology and provenance, about which there are various hypotheses. This ware is characterised by a perfectly drawn and varied iconography, with often stylised zoomorphic and anthropomorphic and nautical motifs. It was produced in an as yet unidentified workshop in North Africa or the Iberian Peninsula. The pottery analysed was found in an archaeological excavation in the Barrio Andalusi of Almería (south-east of Spain). Technologically, the ceramics are fairly homogeneous, with copper-green and manganese-brown pigments applied over the raw tin glaze filled with large undissolved quartz particles. The use of quartz is consistent with a Fatimid-Zirid contribution from Ifriqiya, the use of tin is consistent with an Andalusi Umayyad-Taifas contribution, and the green and brown colours on a white ground to either Ifriqiya or Andalusi. Our study has shown that the use of quartz on the decorated glazed surface is not related to the need for an opacifier, but rather to the need for a highly viscous melt that limits the spread of the pigments during the firing allowing a finer and more detailed drawing. This fusion of different techniques has been identified for the first time. It is intriguing from the historical point of view of medieval technology, and provides the first insights into understanding the technological transfers and technical solutions that took place in the Mediterranean basin during this period.

The variability in Neanderthal behaviour is one of the key debates in Middle Palaeolithic archaeology. Here we present the analysis of the lithic industry from a unit at one of Europe’s main Palaeolithic sites: El Castillo Cave. Unit XXf1.1, dated to the beginning of MIS 4, is an example of human occupation during a period of population decrease. In this assemblage, the technology is organised with the aim of obtaining the largest possible blanks in an environment in which small-sized raw materials predominate, with the presence of imported tools and clear differences in the management of different raw materials. This assemblage is characterized by the predominance of centripetal exploitation methods, and there is only a small number of blanks with laminar tendency, and cleavers. From all this we can observe how Neanderthals were able to find ways to achieve their specific objectives, planning their behaviour to overcome the limitations imposed by the environment.

Ouerping site, an important excavation archaeological site unearthed in 2017 in Jinzhong city, Shanxi province, China, dates back to the Warring States period. Metallographic, scanning electron microscopy coupled with energy-dispersive spectroscopy and energy dispersion-type X-ray fluorescence spectrometer analysis of the site’s iron artefacts revealed that they were made of two types of materials: hypereutectic white iron and cast iron annealed products. Among them, the cast iron is hypereutectic white iron, and the annealed products include decarburized cast iron, cast iron decarburized steel (wrought iron) and ductile cast iron. For the first time, ductile cast iron products were discovered in Shanxi. According to the age of each layer of the site, the craftsman has mastered the cast iron annealed and decarbonization technology since the middle of the Warring States period, and applied it to tools and weapons. Combined with the iron artefacts storage of the site and the construction of building foundations, the iron solid-decarburised production has reached a certain scale, played an important role in social and economic development. The site is rich in solid-decarburised products and has strong time continuity, and the study of them not only reveals the technical connotation of iron production in this area, but also provides important materials for studying the development of cast iron Processing technology and social development in Shanxi and even in ancient China.

Late Middle Palaeolithic Neandertals in France are known to have engaged in the collection and grinding of black minerals rich in manganese dioxide (MnO₂), generally presumed for symbolic use as powdered pigments. However, lab-based experiments conducted by Heyes and colleagues (Sci Rep 6: 22159, 2016) have shown that the addition of powdered MnO₂ to wood turnings both reduces the temperature required for combustion by ca. 80–180 °C and significantly increases the rate of combustion. This special pyrotechnic property of powdered MnO₂ may have been observed and leveraged by Neandertals to aid in fire making—a technology known to Neandertals in this region by at least 50,000 years ago. To test this idea, a series of actualistic fire-making experiments were performed to determine the practical applicability of MnO₂ as a tinder-enhancing additive. The flint-and-pyrite percussive fire-making method was employed to produce sparks that were directed onto eight different types of tinder common to temperate Northwest Europe to determine if and to what degree the addition of MnO₂ powder improved their ability to capture sparks that then propagate into glowing embers. The results show that MnO₂ does indeed considerably improve the ignition efficiency of tinder material over untreated tinder, both in terms of the point of first ignition and the total number of ignitions achieved. It was observed, however, that the incidental addition of pyrite dust onto a tinder over the course of an experiment also appeared to improve its ability to capture sparks. Supplemental experiments using tinder pre-mixed with powdered pyrite confirmed this hypothesis, suggesting pyrite powder similarly expedites fire production. While this finding may raise questions regarding the need for collecting MnO₂ for this purpose, its potential utility may lie in (1) its relative softness compared to pyrite, making it much easier to grind or scrape into powder, and (2) the greater potential for MnO₂-bearing deposits to yield larger quantities of usable raw material compared to pyrite-bearing outcrops, making it relatively more abundant in some areas. Thus, when available, it is clear that adding MnO₂ to tinder would have noticeably reduced the time and energy required to produce fire, making it a potentially novel Neandertal innovation complementary to the fire-making process.

The Iron Age was a period of change, with many innovations in the glass-making technology. The chemical composition of the set of objects considered in the present study demonstrates the diversity of the raw materials used and the depth of knowledge about the manipulation of glass appearance in the eighth-sixth centuries BCE. The study was carried out using fibre optics reflection spectroscopy and portable X-ray fluorescence spectrometry at the museums’ premises to examine a large number of glass beads and preliminarily group them on the basis of their composition and spectral characteristics. In addition, a smaller set of selected samples was analysed by laser ablation inductively coupled plasma mass spectrometry to provide a comprehensive chemical characterisation of the material. The compositional data indicated that the samples belonged to the high magnesium and low magnesium glass compositional types. Only one sample was recognised as low magnesium medium potassium glass. Glasses within each group were made from different sands, suggesting different provenances. Some of the samples were suggested to be of local origin, while the others were interpreted as imported glass. Evidence of glass colouring, decolouring and recycling are also discussed.

This study represents the first extensive residue analysis of prehistoric pottery from northern Belgium. It examines pottery use and culinary practices across the Mesolithic-Neolithic transition, from the late 6th to the early 4th millennium cal BC. Residue analyses were performed on more than 200 samples from nine archaeological sites, representing different cultural groups from this transitional phase. This includes the analysis of charred food residues encrusted on the vessel surfaces by elemental analysis-isotope ratio mass spectrometry (EA-IRMS), gas chromatography-mass spectrometry (GC-MS), stereomicroscopic analysis and Scanning Electron Microscopy (SEM), as well as the analysis of absorbed lipids by gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS). This study provides the first evidence of ruminant dairy fats in Early Neolithic Limburg pottery, supporting the hypothesis that this pottery was produced and used by LBK farmers rather than hunter-gatherer populations. The first indigenous pottery of the Swifterbant culture was frequently used to process freshwater fish (often together with plant foods) and ruminant meat, although several of the studied vessels likely contained mixtures of resources which could also include porcine products. Ruminant dairy is nearly absent from this pottery. Similar results were obtained for pottery of the subsequent Michelsberg culture/Group of Spiere of the late 5th and early 4th millennium cal BC. The limited presence of ruminant dairy fats in this pottery contrasts with the findings for Middle Neolithic pottery from neighbouring regions, providing further evidence for the existence of regional variations in pottery use or culinary practices throughout prehistoric NW Europe. However, our current view of pottery use during the Mesolithic-Neolithic transition in northern Belgium might be biased by the difficulties in distinguishing between wild and domesticated ruminant adipose fats as well as in detecting plant foods through lipid residue analysis.
