Archaeological investigations of ancient climate change have become an important focus for many researchers. A number of studies have focused on scientific techniques to identify the intricate details of the event, and the subsequent impact of these climatic changes on the ecological landscape. These more scientifically oriented studies have allowed the present authors to investigate a more subtle impact on the landscape: trade disruption during ancient climate crises viewed from the rural settlement of Çadır Höyük on the north central Anatolian plateau. The ebb and flow of trade networks in the past can be tied to many external sociopolitical and socioeconomic factors that may have had little to do with the air outside. We investigate here whether climate change was a significant factor that interfered with trade networks during three periods: The 4th millennium BCE Late Chalcolithic (the 5.2 ka climatic event); the late 2nd millennium BCE (3.2 ka climatic event); and the Medieval Warm Period from the 10th to the 13th century CE. This study presents the evidence for regular, and sometimes robust, trade or provision of goods and resources prior to these three climate events, and the disruption or dissolution of these during the height of each climate crisis, particularly in the earlier two periods; in the last period, climate variability was only one of many factors affecting trade networks on the plateau. We profile how the residents of ancient Çadır Höyük managed these intermittent “empty shelves” and filled in gaps using local resources and ingenuity. Full article

Identifying the mineral pigments used in the decoration of prehistoric pottery is a significant step for understanding the evolution of the technological practices over time. On the Balkan Peninsula during late prehistory, the techniques used for red and dark-colored decorations underwent a significant transformation. In the Early Neolithic period, pottery was often decorated with dark-toned paints, ranging from deep red to brown. However, this approach declined noticeably during the Chalcolithic period, when red pigment pseudo-incrustation became the predominant decorative method. This study aims to identify the mineral pigments used in red and dark decorations on Neolithic and Chalcolithic pottery from Bulgaria and to trace possible technological, regional, or chronological variations in their composition. A total of 34 ceramic sherds, decorated in shades from red to brown and black, were analyzed using two complementary spectroscopic techniques: laser-induced breakdown spectroscopy (LIBS) and Fourier-transform infrared spectroscopy (FTIR). LIBS data were further evaluated using principal component analysis (PCA) to classify materials based on elemental composition. The results indicate that red decorations are consistently composed of hematite and remain compositionally stable regardless of the region, time period, or application technique. In contrast, dark decorations contain various combinations of iron oxides (magnetite and hematite) and manganese oxides, often including barium-rich manganese compounds—potentially indicating pigment provenance. Additionally, the dark decorations display regional differences. Full article

This article presents the first results of the zooarchaeological analysis of Chalcolithic levels of the Barrio del Castillo site (Torrejón de Ardoz), located within the Aldovea complex, which also contains evidence from other prehistoric periods. The Barrio del Castillo sector reveals an occupation pattern characterized by pit and silo fields, a common phenomenon in the Tagus Middle Valley’s Prehistory. This study focuses on the Chalcolithic phase, which exhibits two types of faunal accumulations: one linked to domestic activities (referred to as domestic assemblages), and another with a more symbolic character, involving the burial of articulated or semi-articulated animals, mainly dogs, designated as ritual deposits. The first type of accumulation is dominated by domestic species like caprines (sheep and goats) and cattle. Other domestic species, like pigs and dogs, alongside wild species, like horses and deer, appear in smaller quantities. On the other hand, ritual deposits are largely dominated by dogs in the Chalcolithic phase. This paper emphasizes the marked contrast between the two types of accumulations, domestic and ritual, and highlights the implications that these might have toward a better understanding of the world of the first metallurgical communities of the inner Iberian Peninsula.

A first attempt has been made to present a general composition of birds found in Chalcolithic settlements in the plains and lowlands of Bulgaria. Based on data from 21 settlements, 78 bird taxa (including 3 domestic forms) have been identified. Of these, 56 species have been identified to the species level. They constitute 13.4% (almost 1/7) of the 417 recorded bird species in the country. Aquatic birds (waterfowl, grebes, loons, herons, etc.) predominate (29 species). There are 12 species inhabiting woodland landscapes. Ten species are field/openland birds, and five are petrophilous species that inhabit rocky and stony habitats. Five species have disappeared as nesting in the country—bearded vulture, great bustard, common crane, colchic pheasant (native colchicus ssp.), and black grouse. These five species constitute 8.9% of the established composition of birds in the Chalcolithic settlements in the country. One extinct subspecies of the Eurasian coot has been described from one of these settlements. Full article

Beachrock is a sedimentary rock that forms rapidly through the cementation of beach-associated clasts by calcium carbonate within the intertidal zone. On the southern coast of Israel, Holocene beachrock exposures typically appear as linear, shore-parallel platforms that dip seawards. In the archeological record, beachrock was exploited as a natural resource for various purposes, including the production of querns, millstones, basins, building stones, and other architectural elements. At Tel Yavne, a site continuously settled from the Chalcolithic period to the present day, excavations in the eastern and southern fringes revealed an extensive industrial compound dating to the Byzantine and early Islamic periods. This compound underscores the settlement’s economic and industrial prominence during those eras. Numerous beachrock artifacts were uncovered, and this study examines their practical applications while characterizing their composition and microstructure. This research highlights the role of beachrock as a key resource, providing insights into inland–coastal economic interactions in antiquity and broadening our understanding of its use within the socio-economic landscape of the region.

The Late Chalcolithic period in the southern Levant saw notable changes in almost every aspect of daily life. Some of the most significant shifts during this time seem to have been anchored in the subsistence economy and involved food and its cooking, processing, storage, serving, and handling with vessels and tools. The paper offers a comprehensive overview and analysis of one utensil that is likely to have been caught up in these developments—the Late Chalcolithic spoon. While spoons first appeared in the region during the Pottery Neolithic period, the Chalcolithic period witnessed a rise in their frequency and distribution. Nonetheless, they were few in number. While their functions remain unclear, we have presupposed their association with food and kitchenware and have explored them in this vein. This paper delves into their morphological characteristics and distribution and ponders their significance in light of other changes that occurred during the Late Chalcolithic period in the southern Levant.

Remote sensing techniques provide crucial insights into ancient settlement patterns in various regions by uncovering previously unknown archaeological sites and clarifying the topological features of known ones. Meanwhile, in the northern part of the Southern Levant, megalithic structures remain largely underexplored with these methods. This study addresses this gap by analyzing the landscape around Rujm el-Hiri, one of the most prominent Southern Levantine megaliths dated to the Chalcolithic/Early Bronze Age, for the first time. We discuss the type and extent of the archaeological remains identified in satellite images within a broader context, focusing on the relationships between landscapes and these objects and the implications of their possible function. Our analysis of multi-year satellite imagery covering the 30 km region surrounding the Sea of Galilee reveals several distinct patterns: 40–90-m-wide circles and thick walls primarily constructed along streams, possibly as old as Rujm el-Hiri itself; later-period linear thin walls forming vast rectangular fields and flower-like clusters of ~ 20 m diameter round-shaped fences found in wet areas; tumuli, topologically linked to the linear walls and flower-like fences. Although tumuli share similar forms and likely construction techniques, their spatial distribution, connections to other archaeological features, and the statistical distribution in their sizes suggest that they might serve diverse functions. The objects and patterns identified may be used for further training neural networks to analyze their spatial properties and interrelationships. Most archaeological structures in the region were reused long after their original construction. This involved adding new features, building walls over older ones, and reshaping the landscape with new objects. Rujm el-Hiri is a prime example of such a complex sequence. Geomagnetic analysis shows that since the entire region has rotated over time, the Rujm el-Hiri’s location shifted from its original position for tens of meters for the thousands of years of the object’s existence, challenging theories of the alignment of its walls with astronomical bodies and raising questions regarding its possible identification as an observatory.

In the prehistoric period on the Balkan Peninsula, the technology of white decoration underwent a drastic change. At the beginning of the Neolithic white pigment was applied as paint on a polished surface. At the end of the epoch, white paste was inlaid in incised channels on the surfaces of vessels. This study is focused on the identification of mineral pigments used for white decoration of Neolithic and Chalcolithic pottery from the territory of Bulgaria. The aim of this work is to answer the question of whether the composition of the white pigment varies according to the technique of decoration (paint and inlay). A set of 41 pottery fragments from 11 archaeological sites on the territory of Bulgaria was analyzed utilizing two spectroscopic techniques: laser-induced breakdown spectroscopy (LIBS) and Fourier-transform infrared spectroscopy (FTIR). Additionally, the experimental data from the LIBS were statistically treated with the multivariate technique, principal component analysis (PCA). The results from the spectral analysis indicated that the main constituent in the white decorated sherds is calcite in various combinations with carrier materials like quartz, feldspars, and metal oxides. The statistical analysis revealed that the primal constituent in the inlaid sherds is calcite while in the painted part, the carrier material is dominant. In some particular sherds, gypsum, hydroxylapatite, kaolinite, and aragonite were also detected. Full article

Comparison of the ⁸⁷Sr/⁸⁶Sr signatures of archaeological osteological material with features of geological provinces can be applied to determine the places of birth and living of individuals. Such reconstructions were conducted for both humans and domestic animals at the Late Bronze–Early Iron Age sites of the Crimea. The Crimean Peninsula is an interesting testing polygon for such research because it is characterized by a diverse geological situation within a relatively small area. The initial data allowed us to distinguish between three groups of mobility at the Bai-Kiyat I settlement and two groups at the Dolgii Bugor site. The Bai-Kiyat I site is located on the seacoast, so the proxy line for this area will correspond to the value of the ratio of strontium isotopes in seawater (0.7092). The inhabitants of this settlement, including a child from a burial on the settlement, are characterized by this value of strontium isotopes. Other groups include nonlocal people. The data obtained indicate that the steppe zone of the Northern Black Sea region was an ecumene, within which active mobility of groups of people was registered. This mobility is associated primarily with the pastoral type of economy in the period from the Chalcolithic to the Early Iron Age. Full article

The Santa Vitória Chalcolithic site (southern Portugal) prompts several questions related to the provenance and production technology of artefacts. Archaeological ceramics from two sections of Ditch 1 of the Santa Vitória site were studied by neutron activation analysis and X-ray diffraction for the first time, with the main goal of contributing to the contextualization of the artefacts and better understanding their production processes/technologies and the provenance of raw materials. The results point to a local production of ceramics, since their mineral phases reflect the geological contexts around the archaeological site. The mineralogical assemblage indicates a firing temperature below 850 °C. Iron is the better discriminator of ceramics from both sections, which could be related to the addition of different proportions of temper grains during the ceramics’ production. Although trace elements do not serve as discriminating geochemical indicators for the analyzed samples, they do imply a slightly higher heterogeneity in the composition of the ceramic paste from section 2. The negative Eu anomaly found in two samples is in accordance with the lower contents of Na₂O, related to plagioclase weathering. Detailed studies on ceramics and potential raw materials are foreseen to assist in discussing the role of this Chalcolithic archaeological site at a regional level. Full article

This article presents the results of a topographical and analytical study using hh-XRF of 22 gold and gilded objects from the Archaeological and Historical Museum of A Coruña (Galicia, Spain). They are highly representative of the northwestern Iberian goldwork from the Chalcolithic (third millennium BC) to the early Roman period (first century AD). This study contributes to our knowledge of the production techniques used in those periods, as well as their evolution over time. The collection includes some of the most representative types in this area, such as Early Bronze Age “sheet collars” and torcs from the Second Iron Age. In the case of torcs, new data are provided on one of the formally best-documented types (the Artabrian type) and on those known as “Baroque torcs” that are characteristic of the final moments of this goldsmith tradition. While pieces from the Chalcolithic and Early Bronze Age were made with alluvial gold, the torcs from the Late Iron Age contain variable amounts of silver and copper. Also detected is the frequent use of cores made of less precious metals, which were subsequently given a golden appearance using gilding techniques. The new data are discussed in light of our current knowledge of NW Iberian goldwork, one of the most representative of this craft tradition in Western Europe for those periods. Full article

Throughout history, it has been observed that human populations have buried the deceased members of their communities following different patterns. During the Copper Age and the Bronze Age—periods on which this study focuses—in the northern sub-plateau of the Iberian Peninsula, we identified different patterns of multiple or collective burial. This work analyzes a total of 58 individuals buried in different multiple or collective graves, to investigate whether the practice of these burials implies a family or biological link between individuals buried together. With this aim, STR markers of nuclear DNA were analyzed, as well as the hypervariable regions I and II of mitochondrial DNA, establishing both close kinship relationships and relationships through maternal lineage. We observed different burial patterns, detecting certain maternal lines preserved in some common burials maintained over time. Close family relationships were observed to a lesser extent, with some occasional exceptions. The results of the analysis formed the basis for a discussion on the concepts of family and community.

Wood and basketry artefacts rarely survive in the prehistoric record since they require exceptional conditions for preservation; as a result, the current knowledge about when and how prehistoric societies used these basic organic raw materials is limited. Focusing on the southern Levant, we discuss for the first time a collection of 16 late prehistoric organic artefacts found in underwater research conducted in the last forty years off the coast of the Carmel Ridge (Israel). The waterlogged finds, including bowls, shafts, a wedge, a trough, a pitchfork, logs, a mat, and a basket, were found at sites spanning from the Pre-Pottery Neolithic to Middle Chalcolithic periods (ninth–seventh millennia cal. BP), constituting an unprecedented record of prehistoric wood and other perishable materials, providing us with new information about raw material preferences and manufacturing technologies.

Pottery is a complex archaeological material that is found ubiquitously in various spatial—temporal frameworks from all over the world; therefore, it is of great importance to archaeological research. The current paper aims to present and discuss the results obtained on a batch of Neolithic (ca. 6000–5000 BC) and Chalcolithic (ca. 5000–3900 BC) pottery sherds from Southern Romania through X-ray Computed Tomography, a non-destructive methodology that allows for the 3D reconstruction and precise measurement of inclusions and voids present within ceramic artefacts. Images from several potsherds were subsequently exported and analyzed by means of dedicated software (ImageJ 1.54p and GIMP) to extract quantitative information on the observed features. Grain size and morphometric analyses were performed on the particles, while the contour variability of the examined inclusions was characterized through the application of shape descriptors. Voids were analyzed in order to reveal specific orientation patterns through the examination of the aspect ratio of the holes and of the Rayleigh z test values. These analyses evidenced the general reliance of moderately and poorly sorted clays for ceramic production, accompanied by a gradual transition from organic to grog tempering, while conservative traditions remained prevalent in primary pottery-forming processes.

The chronological period from the beginning of the Chalcolithic Age to the end of the Bronze Age on the Iberian northern sub-plateau of the Iberic Peninsula involves interesting social and cultural phenomena, such as the appearance of the Bell Beaker and, later, the Cogotas I cultures. This work constructs a genetic characterisation of the maternal lineages of the human population that lived on the northern sub-plateau between 5000 and 3000 years ago through an analysis of mitochondrial DNA (mtDNA), a kind of genetic marker that is inherited through maternal lineages, unaltered from generation to generation. Population and cultural questions are investigated through mtDNA analyses. This study intends to shed light on the following questions. Were individuals who were buried together in multiple or collective burials biologically related through their maternal lineages? Were there distinct maternal human lineages in the same or different geographical areas if different material cultures (Bell Beaker and Cogotas I) were associated with the arrival of new human populations who established close biological relationships with the endogenous populations? Or could this be the result of the transmission of knowledge without human populations mixing? Another important question is whether the material cultures were related to the female populations. We analysed 91 individuals from 28 different archaeological sites of the Iberian northern sub-plateau from four different chrono-cultural periods (Pre-Bell Beaker, Bell Beaker, Proto-Cogotas I, and Cogotas I), from the end of the Chalcolithic Age up to the Bronze Age. There were two historical moments of new populations arriving: the first during the Pre-Bell Beaker period, associated with the K mtDNA haplogroup, and the second during the Proto-Cogotas I culture, with new lineages of the H, HVO, and T haplogroups. Neither of these new population flows were directly associated with the maximum development of the two main material cultures Bell Beaker and Cogotas I, so they must have occurred immediately beforehand, during the Pre-Bell Beaker and Proto-Cogotas I periods, respectively. However, we cannot discard an association between the populations and material cultures. Curiously, it has also been observed that there was also a tendency towards multiple burials, in which the individuals who were buried together belonged to the same maternal lineage, during these two periods of population change. This study has shed some light on the populational changes that occurred through these different periods in this specific geographical area of the northern sub-plateau of the Iberian Peninsula.
