Use of osseous materials during the Chalcolithic in Northeastern Bulgaria (based on materials of Polyanitsa tell)

Many Chalcolithic cultures of the Balkan-Danube region used antler, animal bones, boar tusks and shells as raw materials for tools, household and votive items, as well as jewelry. The unique collection of such objects found in 1973–1974 during the archaeological study of the Polyanitsa tell (Northeastern Bulgaria), is particularly numerous and diverse (266 items). Experimental and traceological studies of part of this collection made it possible to characterize the manufacturing technology of these products, as well as the functional purpose of many of them. Among the industrial equipment, tools were found that were used in agriculture, processing flint, wood, hides and skins, and ceramics. It should be noted that some flint tools, found at the settlement, were used for processing bone/antler. This fact, as well as finds of blanks and unfinished items made of bone/antler, indicate their local production. The quality and the wide range of products of the bone processing industry serve as proof of the high level of its development and demand for such utensils in the economic and domestic activities of the population of the Chalcolithic sites of Northeastern Bulgaria.

Identifi cation of Adhesives for Repairing Ancient Ceramics: The Case of the Neolithic and Chalcolithic of Far Northeast Europe

This study focuses on the composition of the adhesives used to repair clay vessels, and on the technique of their preparation in the Late Neolithic and Chalcolithic (late 4th to early 3rd millennia BC) sites of Far Northeast Europe (the Republic of Komi and the Nenets Autonomous Okrug). Remains of adhesives were detected on 70 of 171 repaired pots. To date, five samples of ceramics from dwellings of the Chuzhyael culture have been analyzed. Gas chromatography-mass spectrometry revealed no markers of coniferous trees or bitumen; but did reveal markers of birch, suggesting that fractures and cracks on broken pots were plastered with birch tar. The composition of organic compounds in samples indicates the use of two vessels in the technological process: in one of them, birch bark was subjected to pyrolysis, while the other was a receptacle for tar. This comparatively complex technology reveals one more specialization in the domestic manufacture of the taiga hunter-gatherers, including the use of special furnaces. Analytic procedures employed by us open up new prospects for the study of the material culture of Far Northeast Europe, extend our knowledge of domestic manufacture, and offer new material for AMS dating.

Stone arrows from the Chalcolithic sites of the Middle Kama basin

The article is devoted to the analysis of stone arrows discovered as a result of archaeological excavations of settlements of the Garin Chalcolithic culture in the Middle Kama region. The basis of the study is a typological analysis, in addition, the characteristics of secondary processing, metric parameters, proportions and a description of raw materials are given. As a result of the work, 578 specimens of whole and fragmented arrows from seven sites were analyzed. The studied items were made from raw materials of local origin using the technology of secondary bifacial thinning. The absolute majority of finished arrows shapes have a leaf-shaped shape with various variations in the design of the base, in addition, pentagonal tips with a concave or truncated base are common. Other types of products (willow-leaved, triangular, rhombic and petiolate) are less common. Such arrows shapes are typical of the Garin culture and can be found in the materials of most of the Chalcolithic sites of the Upper and Middle Kama region. On the territory of the Lower Kama region, the Kamsko-Vyatka interfluve and the European Northeast, similar forms of leaf-shaped and rhombic tools are known. At the same time, pentagonal, triangular and willow-leaved tips are less common and, most often, are represented by single specimens. The results of the study show that the technology of bifacial cleavage was widely developed in the Upper and Middle Kama region during the Chalcolithic era. It is likely that the traditions of the production of bifacial tools were formed in the process of cultural interaction. The information obtained during the research requires further understanding and reflection.

Fingerprinting Ceramics from the Chalcolithic Santa Vitória Enclosure (SW Iberia)

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.

Chemical and mineralogical characterization of late chalcolithic pottery (ca. 3700–3300 BCE) from southwest Anatolia (Türkiye)

This paper presents the results of chemical and petrographic investigations on the late chalcolithic (ca. 3700–3300 BCE) pottery from the Burdur Lake region in southwest Anatolia (Türkiye). Twenty-one ceramic sherds and a clay lump from four different levels of the late chalcolithic site of Kuruçay Höyük (Burdur) were examined with thin section petrography, XRF, and XRD to illuminate the element and mineral compositions of the ceramics. The chemical compositions and their statistical evaluation demonstrate the continuous use of at least two local clay sources within each different phase of the late chalcolithic. While sources stay the same, petrographic thin section analysis implies a change in the clay preparation techniques. This is visible via the homogeneity of the clay matrix and the existence of shell and lithic inclusions in the paste. About the end of the late chalcolithic period, clay preparation appears to be enhanced conceivably with the changing technological setting of the period toward the early bronze age.

New virtual approach to the study of metallurgy through the analysis of slice marks from the Chalcolithic site of Zanjillas (Torrejón de Velasco, Madrid, Spain)

AbstractAlthough the discovery of metal objects is not common in Chalcolithic or Bronze Age sites, the study of bone surface microscopic grooves from animal butchering can yield evidence of the use of metal artefacts in these contexts. Additionally, the presence of slice marks made with metal objects in Chalcolithic and Bronze Age sites has highlighted the use of metal in common practices beyond their ornamental application, as usually expected at the early stages of metallurgy. Here, we present the study of the slice marks found at the Chalcolithic site of Zanjillas, using geometric morphometrics and machine learning algorithms, with the aim of identifying the nature of the tools used for carcass processing at the site. For this purpose, we replicate previous analyses considering slice marks produced with lint flakes and metal tools to generate a referential framework that serves as comparative to the Zanjillas sample. Our results suggest that most of the domestic activities related to carcass skinning, defleshing, or evisceration in Zanjillas were still performed with flint artefacts.

Stone Decorations from the Chalcolithic Sites of the Upper and Middle Kama Region (an attempt at complex analysis)

The purpose of the article was a comprehensive study of stone decorations from the Chalcolithic sites of the region. The authors used petrographic description, typological and use-wear analysis. The authors examined 40 items from 6 archaeological sites located in the Upper (2) and Middle (4) Kama region. The jewelry was made of serpentinite of varying degrees of hardness. Serpentinite could originate from the Saranovsky and Moivinsky deposits in the Perm region. The shape of the products was divided into 5 groups, among which the leading ones were oval and teardrop-shaped. Most of the jewelry had a single through hole, which was more often located in the upper part of the product and was drilled on one side. The use-wear analysis made it possible to identify traces from the manufacture of jewelry, traces from use and traces that appeared as a result of the archeologization of objects. Most products were treated as patches on clothing. The shape and quality of jewelry could depend on both the hardness of the raw materials and the skills of the master. They don't create standard groups. The closest analogies can be found in the ornaments studied at the Ust-Kama burial grounds. The population that left these burial grounds could take part in the formation of the Chalcolithic cultures of the Kama forest.

First evidence for alloying practices in the Chalcolithic Southern Levant (4500–3800 BCE) as revealed by metallography

Excavations at the Chalcolithic site Fazael in the central Jordan Valley uncovered a large number of metal items, many of them polymetallic copper alloys cast in the lost wax technique. Metallography and SEM–EDS analysis on a subset of the assemblage confirm previous notions of the lost wax metallurgy in the Chalcolithic Southern Levant but extend them significantly in three aspects: The Fazael metal assemblage is slightly depleted in its arsenic content compared to metal assemblages from other sites, silt-sized quartz inclusions in unalloyed and polymetallic copper items, and the presence of unalloyed copper inclusions. These latter provide the earliest direct evidence for mixing of different metal types in West Asia, potentially alloying or recycling.

Identification of Fazael 2 (4000–3900 BCE) as first lost wax casting workshop in the Chalcolithic Southern Levant

Apart from many lost wax cast metal fragments, crucible fragments and several heated sediment nodules were found at the Chalcolithic site Fazael 2 (central Jordan Valley). Petrographic investigations on the heated sediment nodules revealed many features characteristic of the Chalcolithic Southern Levantine lost wax casting moulds. Heating temperatures were assessed using infrared spectroscopy, showing that casting did not vitrify the clay fraction in the moulds. Consequently, Fazael is the first identified Chalcolithic Southern Levant production site for lost wax cast metal items. These findings confirm the existence of a metallurgical tradition with lost wax casting in the Jordan Valley parallel to the unalloyed copper metallurgy in the Northern Negev. Moreover, crucibles and heated sediment nodules are made of local ferruginous loess, a material not mentioned in previous studies on lost wax casting mould fragments. Therefore, the existence of more than one such production site must be assumed.

A Chalcolithic Burial in the Mountain-Forest Zone of the Trans-Urals

We describe an unusual burial at a stratifi ed Chalcolithic site Shaitanskoye 4-6 on the coast of the eponymous lake in the Sverdlovsk Region. An individual, aged 18–35 was buried in an oval fl at-grave pit, 1.6 × 0.56 × 0.2 m in size. We give a detailed description of sixty funerary items, made of stone: three unusually large knives manufactured on thin chert plates (the nearest outcrops are found in Northern Kazakhstan and Southern Urals); a projectile head, 19 arrowheads, 18 fl int bladelets from a side-bladed tool, a polished axe-adze, a composite tool on a blade, two plates with use-wear traces, and 15 beads. Notably, some of the artifacts are made of “southern” rocks. The results of the isotope analysis indicate considerable mobility and close ties between populations of the forest and steppe Trans- Urals in the 4th and 3d millennia BC. The Chalcolithic site, which, apart from the burial, includes habitation deposits with numerous artifacts such as ceramics of various types, lithics including a large series of arrowheads and several fl int fi gurines, can be viewed as a complex archaeological object where, among other activities, rites were performed securing group consolidation.

Revealing invisible stews: new results of organic residue analyses of Beveled Rim Bowls from the Late Chalcolithic site of Shakhi Kora, Kurdistan Region of Iraq

Beveled Rim Bowls (BRBs) are the most iconic and well-known vessel type of ancient Southwest Asia. Roughly and carelessly produced, these conical bowls are attested in their thousands at 4th millennium BCE sites from southern Iraq and the Persian Gulf to the highlands of eastern Turkey and Iran. Questions regarding their function and relationship with emergent state institutions have stood at the centre of nearly a century of debates about the nature of early Mesopotamian urbanism and the so-called Uruk Expansion. In this paper we present the results of organic residue analyses of 10 BRBs from the site of Shakhi Kora in the Sirwan/Upper Diyala River Valley in the Kurdistan Region of north-east Iraq. Our analytical results challenge traditional interpretations that see BRBs as containers of cereal-based rations and bread moulds. The presence of meat- and potentially also dairy-based foods in the Shakhi Kora vessels lends support to multi-purpose explanations and points to local processes of appropriation of vessel meaning and function.

Non-destructive characterisation of dolerite archaeological artefacts

A methodological proposal for the characterisation of dolerite rock aiming to test a non-destructive and non-invasive analytical approach has been developed. Geological samples were collected from several natural outcrops and studied together with seven archaeological stone tools found in a Chalcolithic site of the southern Valencian Community (Spain). The samples were analysed employing portable energy dispersive X-ray fluorescence spectroscopy, Raman microspectroscopy and Fourier transform near infrared spectroscopy. The obtained data were statistically processed in order to evaluate affinities and differences among the geological outcrops and to evaluate the possible provenance of the stone tools. The results of the different techniques were compared and evaluated. The three techniques showed results that were in most of the cases consistent one with each other, suggesting that combining multielement analysis and Raman could be a good way to identify stone tools raw material procurement, being the prior step for the reconstruction of ancient exchange networks.

Supporting Long-Term Archaeological Research in Southern Romania Chalcolithic Sites Using Multi-Platform UAV Mapping

Spatial data play a crucial role in archaeological research, and orthophotos, digital elevation models, and 3D models are frequently used for the mapping, documentation, and monitoring of archaeological sites. Thanks to the availability of compact and low-cost uncrewed airborne vehicles, the use of UAV-based photogrammetry matured in this field over the past two decades. More recently, compact airborne systems are also available that allow the recording of thermal data, multispectral data, and airborne laser scanning. In this article, various platforms and sensors are applied at the Chalcolithic archaeological sites in the Mostiștea Basin and Danube Valley (Southern Romania). By analysing the performance of the systems and the resulting data, insight is given into the selection of the appropriate system for the right application. This analysis requires thorough knowledge of data acquisition and data processing, as well. As both laser scanning and photogrammetry typically result in very large amounts of data, a special focus is also required on the storage and publication of the data. Hence, the objective of this article is to provide a full overview of various aspects of 3D data acquisition for UAV-based mapping. Based on the conclusions drawn in this article, it is stated that photogrammetry and laser scanning can result in data with similar geometrical properties when acquisition parameters are appropriately set. On the one hand, the used ALS-based system outperforms the photogrammetric platforms in terms of operational time and the area covered. On the other hand, conventional photogrammetry provides flexibility that might be required for very low-altitude flights, or emergency mapping. Furthermore, as the used ALS sensor only provides a geometrical representation of the topography, photogrammetric sensors are still required to obtain true colour or false colour composites of the surface. Lastly, the variety of data, such as pre- and post-rendered raster data, 3D models, and point clouds, requires the implementation of multiple methods for the online publication of data. Various client-side and server-side solutions are presented to make the data available for other researchers.

Long-distance trade in the Middle Chalcolithic of the southern Levant: The case of the olivine beads from Tel Tsaf, Jordan Valley, Israel.

Eight olivine beads found at the Middle Chalcolithic site of Tel Tsaf (ca. 5,200–4,700 cal. BC), Jordan Valley, Israel, underscore a new facet of interregional exchange for this period. The current paper presents the olivine beads assemblage, its morphometric and technological characteristics, and chemical composition. The results of the chemical analysis suggest that all eight beads derive from the same source. By means of comparison with the chemical characteristics of known olivine sources, we argue for a northeastern African–western Arabian provenience and cautiously suggest Ethiopia as a probable origin. Finally, we discuss the significance of the assemblage, its possible origin, and the mechanisms that may have brought the beads to the site.

Science Revealing Ancient Magic: Phytolith Evidence from the Early Chalcolithic Site of Isaiia (Eastern Romania).

Simple SummaryThe present paper aims to present the newsworthy results and interpretation of the interdisciplinary analysis conducted at an Early Chalcolithic settlement (Isaiia, Romania). The archaeological campaigns of 2015 and 2017 offered remarkable results including a ceramic vessel, inside which an anthropomorphic figurine (with pregnancy depiction) and a small cone, both made out of clay, were found. Given the special character of the deposition, we collected several samples from the vessel and near it for phytolith analysis; samples of bone found next to the pot and from the nearby features were also dated by AMS radiocarbon. The palaeobotanical evidence based on the phytolith analysis showed that cereals and probably mugwort seem to have been in association with the small artefacts; both, and especially the latter, are known, aside from their practical uses (as aliment or remedy), as powerful symbols, used through the ages in magic practices. All of these facts nuance and augment the cultic interpretation of the deposition as a result of a ritual related to fertility (possibly to counteract some physiological problems or reproductive disorders) involving both feminine and masculine symbols and the use of plants.The article presents the palaeobotanical investigations of a remarkable discovery from the Early Chalcolithic settlement of Isaiia–Balta Popii (Romania), a multi-layered site. The excavation of a dwelling brought to light a rather rare finding, meaning a medium sized ceramic vessel having deposited inside two objects of burnt clay: an anthropomorphic figurine depicting pregnancy attributes and a small cone. Given the special character of the deposition, several samples from the vessel and near it were collected for phytolith analysis. Our results highlighted a ritual plant deposition: Elongate dendritic and Blocky morphotypes suggest that cereals and probably Artemisia seem to have been used for this purpose. These plants are known, aside from their practical uses, as powerful symbols, used through the ages in magic practices. All of these facts are strong arguments to interpret this find as a result of a ritual related to fertility involving both feminine and masculine symbols and plant use.

Chalcolithic Painted Pottery of the Sialk III Period: Quantifying Stylistic Continuities and Changes on the Northern Central Plateau

ABSTRACT In the last two decades, the Varamin Plain to the southeast of Tehran has been the focus of intensified archaeological work, with surveys and excavations yielding new insights into the region’s settlement history. New material from the dynamic network of Chalcolithic sites on the Jajrud alluvial fan now offers a more solid basis to assess the links between the Varamin Plain and the site of Tappeh Sialk in the Kashan Plain, which still remains a reference point for this period. In this paper, we use painted pottery to examine the dating and relationships of the settlements of Ahmadabad-e Kuzehgaran and Chaltasian on the Varamin Plain to Tappeh Sialk. Based on an in-depth quantitative analysis of motif assemblages at the three sites, we evaluate contemporaneities as well as stylistic similarities and differences. We highlight both shared temporal trends and regional specificities.

Foodways of an agro-pastoral community: Organic residue analysis of pottery and stone vessels at Middle Chalcolithic Tel Tsaf

Tel Tsaf is a Middle Chalcolithic (ca. 5200–4700 cal BC) site located in the central Jordan Valley, Israel. The site reflects increasing long-distance trade, organized cereal crop cultivation and possibly olive horticulture. Organic residue analysis of lipids recovered from 100 pottery vessels and three stone vessels and comparison to the botanical and faunal remains suggest that the vessels were used to contain or process various combinations of domestic animal and plant products and that these food products were supplemented by local wild plants. This shows direct continuity of dietary traditions from the preceding Neolithic period; however, there were some developments within the suite of domesticated resources, including the earliest direct evidence for milk exploitation in the southern Levant. Culinary traditions incorporated recipes where these food products were cooked and consumed together in various combinations. These dietary patterns were a part of daily life at Tel Tsaf, adding another layer to our understanding of the village and the culinary traditions of the Middle Chalcolithic period in the southern Levant.

Prehistoric Farming Settlements in Western Anatolia

Recovery of archaeobotanical assemblages from Late Chalcolithic Bakla Tepe and Liman Tepe in western Anatolia has provided the opportunity for in-depth analysis of agricultural strategies and the organisation of farming-related activity at the two sites. We find that Late Chalcolithic farmers utilised five major crop taxa, potentially including two mixed crops. The two sites also provide the first evidence for Spanish vetchling and winged vetchling cultivation in prehistoric Anatolia and the earliest evidence for this practice to date anywhere. We suggest that the settlements were organised into small, co-residential households that processed and stored their own crops, but we also propose that potentially communal extra-household storage and high levels of social monitoring may attest to supra-household cooperation. The later agricultural history of the vetchling species and the prevalence of extra-household storage at sites in coastal western Anatolia and the eastern Aegean islands add to evidence for a cultural koine between these regions in the fourth and third millennia bc. We also suggest that the large size of extra-household storage structures and the narrow range of crops cultivated at some Late Chalcolithic sites are consistent with the emergence of more extensive farming systems than those of earlier periods. Evidence for the use of extensive agricultural production to amass arable wealth by the citadel elites of later Early Bronze Age western Anatolia suggests that the agro-ecological foundations for emergent wealth inequality within the region were laid during the Late Chalcolithic. Testing this hypothesis through direct evidence for the nature of Late Chalcolithic farming systems is a key aim of ongoing research.
