The oldest human traces north of the Carpathians (Kończyce Wielkie 4, Poland)

In the area of the Kończyce Wielkie quarry (middle-southern Poland), the Quaternary deposits of different genesis crop out. The lower fluvial series is overtopped with the glacigenic sediments occurring below the Matuyama–Brunhes boundary. This ice-sheet advance is correlated with the Günz and with the oldest traces of glaciations in Western Europe. Culture materials were located within layer of fluvial sands with fine-grained gravels, below the boulder pavement and diamicton – interpreted as till. Raw materials inventory are local flint and hornstone, also foreign flint, hornstone, quartzite, opalite and gneissose granite. The inventory contained macrolithic and microlithic cores, flakes and tools. The tools are made from pebbles, flakes and microlithic-flakes.     

A REVIEW OF THE LATER UPPER PALAEOLITHIC IN THE ODER AND VISTULA BASINS IN THE LIGHT OF RECENT RESEARCH

Summary. The withdrawal of the Vistulan ice-sheet some 15,000 years ago permitted colonisation of the Oder and Vistula basins by a succession of Late Upper Palaeolithic peoples, amongst whom various distinct groups can be recognised. Magdalenian, Shouldered Point, Curved Back Point and Tanged Point technocomplexes are distinguished by the author, who discusses them with reference to the salient features of the archaeological assemblages, comments on the dating evidence, and considers both internal variability and possible relationships with industries in Western and Eastern Europe. The populations of this region, which coincides approximately with the boundaries of modern Poland, were hunter-gatherers exploiting late glacial and early postglacial game resources, but there is evidence that systematic use was made of other local resources, such as ochre (mined at Rydno), Jurassic flint and the chocolate flint of the Holy Cross Mountains. In this process some of the Late Upper Palaeolithic peoples travelled long distances and established wide contacts. Use of the chocolate flint by Swiderian groups of the Tanged Point technocomplex is proving to be a particularly worthwhile study: flint of this kind is found at some 300 out of 700 Swiderian sites. Actual quarrying places are known in the source area, with working and living sites occurring at various distances from them, offering considerable potential for a study of contemporary economic and social organisation and seasonal migration.     

Early Neolithic Sites at Brześć Kujawski,Poland: Preliminary Report on the 1976–1979 Excavations

Abstract

Since 1976, excavations have been conducted on two neighboring Early Neolithic sites at Brze?? Kujawski, Wloclawek district, Poland. The aim of this research is to improve the understanding of the developmental sequence of Early Neolithic cultures on the Polish lowlands as well as to recover palaeobotanical and archaeozoological materials to study the changes in subsistence patterns over time. There are three components of Early Neolithic settlement at Brze?? Kujawski: the Linear Pottery, Early Lengyel, and Late Lengyel cultures, which span the period between 4300 and 3000 radiocarbon years B.C. Large amounts of animal bones indicate a shift from cattle-centered stockbreeding in the Linear Pottery component to a very diverse pattern of animal exploitation in the Late Lengyel component. Early Neolithic house remains, storage pits, flint industries, and copper artifacts are also discussed.     

Flint procurement strategies in the Late Lower Palaeolithic recorded by in situ produced cosmogenic 10Be in Tabun and Qesem Caves (Israel)

The in situ produced cosmogenic beryllium isotope, ¹⁰Be, in flint artifacts from different layers in prehistoric caves can provide information on flint procurement. The buildup of ¹⁰Be in a flint matrix is related to the exposure time of the flint to cosmic rays. Although this exposure history can be complex, the ¹⁰Be content of flint assemblages can show whether the raw material was obtained from shallow mining and/or surface collection as opposed to sediments two or more meters below the surface. Flint artifact assemblages from two Palaeolithic caves in Israel, Tabun and Qesem, were analyzed.In Tabun cave the flint artifacts from Lower Layer E (Acheulo-Yabrudian, around 400 000–200 000 yr) contain very small amounts of ¹⁰Be, which is consistent with flint procured from sediments two or more meters deep. Artifacts from above and below Tabun Lower Layer E show a more complex distribution, as do artifacts from all layers of Qesem cave (Acheulo-Yabrudian). This is probably due to the fact that they were surface collected and/or mined from shallow (less than 2 m) depths. We show here that artifact assemblages have different concentrations of ¹⁰Be, indicating different raw material procurement strategies.     

PREHISTORIC FLINT MINES AND THEIR IDENTIFICATION AS SOURCES OF RAW MATERIAL

This paper is a statistical and geological study of the results of analysis of flint from British and West European flint mines, carried out by emission and atomic absorption spectroscopy. Groups of flint specimens were studied from each geographically separate flint mining area. Flints were analysed for a group of easily measured trace elements shown by previous work to be generally present. The ratios between the trace elements form a consistent pattern for each flint mine and statistically valid differences of pattern can be recognized between different flint mines. A geological investigation shows that the measured trace elements may be derived from clay minerals and explains geographical and statistical variation in the composition of flint in terms of its mode of origin in the chalk. An advanced statistical technique allows individual flint specimens of unknown origin to be attributed by their composition to one or other of the identified flint sources. The archaeological implications of this study are discussed.     

Unusual burial from an early Neolithic site of the lengyel culture in central Poland: Punishment,violence or mortuary behaviour?

During excavations at the Early Neolithic site of the Brześć Kujawski Group of the Lengyel Culture in Osłonki (central Poland), an atypical burial of an adult male was discovered. The individual's skeleton revealed traces of several perimortem injuries: both broken shins (the right shin with two fractures), a large fracture to the frontal bone and about 25 cut marks made with a flint blade in the parietal‐occipital region of the cranium on the left side. The arrangement of the fractured parts of the lower limbs might suggest that the injuries were intentionally exposed. Due to the relatively rich grave goods, it seems unlikely that the buried person was rejected by the community and thus killed or stigmatized by mutilation of the cadaver. The way the cuts were made is different from the cases of scalping or severing muscles in cannibalistic or mortuary practices known from the literature. This burial probably reflects some special funerary rite, which is now difficult to reconstruct or interpret. It is both possible that the observed injuries resulted from wounds that led to the individual's death (perhaps in circumstances that motivated the other special features of the burial) or that they were inflicted on the dead body. Taking into account the probable practices of dismembering of the dead body or human sacrifice found in the later Neolithic period in Poland, all of these possibilities may be considered with respect to this burial.

FLINT PROCUREMENT AND NEOLITHIC AXE PRODUCTION ON THE SOUTH DOWNS: A RE-ASSESSMENT

Summary. This paper reviews the evidence for Neolithic flint axe production on the South Downs in the light of recent chemical analysis of axes and the author's own research involving surface flint collections. The organisation, status and chronology of the Sussex flint mines is discussed and the distribution of flint axes described. Late Neolithic/Early Bronze Age settlement is shown to concentrate on the clay-with-flints which is also a major flint source. It is argued that the production of axes from mined flint was replaced by utilisation of surface deposits in the later Neolithic and case studies are presented.     

PROVENANCING FLINT ARTEFACTS WITH ICP–MS USING REE SIGNATURES AND Pb ISOTOPES AS DISCRIMINANTS: PRELIMINARY RESULTS OF A CASE STUDY FROM NORTHERN SWEDEN

Archaeological flint artefacts from the late Mesolithic/early Neolithic site of Vuollerim, northern Sweden, have been geochemically investigated with ICP–SFMS and MC–ICP–MS in search for the geological/geographical origin of the non‐local flint. The Vuollerim flints were compared with reference samples from Denmark (Cretaceous/Tertiary flint) and Russia (Carboniferous flint). Elemental concentrations as well as elemental ratios for REEs and isotopic ratios for Pb and Sr are presented. Significant differences were found between different geological/geographical contexts. Two of the Vuollerim samples can be ascribed a South Scandinavian origin. Possibly also eastern flint is present, although the results are not conclusive in this case.     

Debitage variability among multiple flint knappers

Five flint knappers produced both multidirectional cores and early stage bifaces. The debitage assemblages were compared to evaluate if, and to what degree, the debitage created by one flint knapper varies from that of other flint knappers. The debitage from these reduction episodes was then analyzed with commonly used and replicable debitage attributes. Each knapper was evaluated in terms of his/her individual consistency, and the debitage produced was tested for each ratio scale debitage attribute to ensure that the variability found between knappers was not a product of variation within the assemblages of the individual knappers. The debitage from the individual flint knappers was found to be highly variable between knappers for both technologies.     

An investigation of the fractal properties of flint microwear images

This paper reports on an investigation into the fractal dimensions of flint microwear images which has been carried out in an attempt to resolve the existing controversy over the possibility of identifying microwear types from visual inspection of high magnification images, and describes a new method for flint microwear image analysis based on fractal geometry. Fractal dimensions of surface images, which are known to relate well to human visual perception of roughness, have been computed for various types of microwear. No significant correlations have been found between the fractal properties of the digital flint images and the contacted materials.     

Formation of Fluid Inclusions during Heat Treatment of Barremo‐Bedoulian Flint: Archaeometric Implications

At the end of the fifth millennium bc , the development of a specialized lithic industry in the Chassey societies of south‐eastern France and its dissemination as far as Catalonia and Tuscany attest to important socio‐economic changes in the Mediterranean Neolithic societies. The lithic production was made on barremo‐bedoulian flint that was heat‐treated to improve the sharpness of the tools produced. Microscopic observations of archaeological and geological, heated and unheated barremo‐bedoulian flint samples allowed us to highlight the heat‐induced formation of fluid inclusions. Microthermometry analyses showed that these inclusions contain pure H₂O, most probably resulting from the dehydration of length‐slow (LS) chalcedony and the closure of narrow pores, according to the model proposed by Schmidt et al. ( 2012 ). Our results enable us to estimate the heating temperatures used by Chassey artisans to ≈ 230°C. We also propose the ‘pressure cooker’ model to explain the migration of liquid water in flint nodules heated to 230°C. Then, we discuss the ability of a particular type of flint to be heat‐treated, and hence its value for Neolithic society, which depends on: (1) the amount of LS chalcedony that ensures the water release at relatively low temperature; and (2) on the total volume of porosity available to store the dehydration water.     

Reconstruction of the Late Glacial and Early Holocene landscape and human presence in Lubrza,Western Poland,on the basis of multidisciplinary analyses

This paper presents the results of a multidisciplinary study that combines archaeological and palaeoenvironmental research to examine the relationship between environment and human activities in Western Poland during the Late Glacial and Early Holocene. The study area lying within the young moraine landscape produced several Late Palaeolithic and Early Mesolithic sites, varied in terms of size and function. Analyses of pollen, plant macro-remains and molluscs accompanied by geomorphological investigations and supported by series of radiocarbon dates have enabled a detailed reconstruction of environment. It has shown that despite climatic fluctuations during the Allerød and Younger Dryas, the studied area provided favourable conditions for hunter-gatherer occupation. The presence of micro- and macroscopic charcoal, charred particles of herbaceous plants and charred mosses in peat deposits of former water bodies evidence various activities carried out by Federmesser and Swiderian groups, for example setting up camp-fires and deliberate burning of the local marsh vegetation. Usewear analyses of flint implements have revealed further traces of diversified human activities undertaken at examined sites. Most importantly, this article focuses on plant-based craft activities undertaken by hunter-gatherers, about which little has hitherto been known.     

Extensive Paleolithic Flint Extraction and Reduction Complexes in the Nahal Dishon Central Basin,Upper Galilee,Israel

Recently found open-air flint extraction and workshop sites in the Eastern Galilee, Israel, are the focus of this paper. Lithic assemblages from among a few of the thousands of tailing piles documented in a field survey, indicate mostly late Lower Palaeolithic/Middle Palaeolithic and rarely Neolithic/Chalcolithic affinities. These discoveries substantially increase our knowledge of the scope of lithic extraction and reduction in northern Israel in these periods. The new sites are located on a 25 km² outcrop of flint-bearing Eocene limestone indicating intensive extraction of large amounts of flint, possibly beyond immediate local consumption requirements. After describing the new sites, we discuss their relation to nearby Middle and Lower Palaeolithic sites; possible resource management scenarios; chronology and duration of the extraction and reduction activity; and the sites as possible landmarks. A key question is the extent of the flint distribution area, or, more precisely, whether this region was a dominant mega-quarry for northern Israel and/or Southern Lebanon in the periods discussed.     

Heat treatment in the South African Middle Stone Age: temperature induced transformations of silcrete and their technological implications

It was recently found that silcrete raw material was heat-treated during the South African Middle Stone Age (MSA) for altering its flaking properties. This finding led to hypotheses about the implications for the MSA hunter-gatherers such as the cost of thermal treatment in terms of investment and firewood. To date, these hypotheses lack a solid basis, for data on the thermal transformations of South African silcrete and, hence, the necessary heating procedure and heating environment, is missing. In order to produce such data, we conducted an experimental study within the framework of the Diepkloof project. This work is based on the petrographic, mineralogical and structural analysis of South African silcrete from the West Coast and its thermal transformations. Our results shed light on the nature of these transformations, the ideal heating temperatures and the tolerated heating speed. The processes occurring in silcrete are comparable to flint, i.e. the loss of chemically bound ‘water’ and the formation of new Si–O–Si bonds, but their intensity is less pronounced. Effective heating temperatures are significantly higher than for flint and the heating speed tolerated by South African silcrete is relatively fast. These findings imply that silcrete heat treatment cannot be directly compared with flint heat treatment. Unlike flint, heating silcrete does not require the setup of a dedicated heating environment and may have been performed in the same time as other fire related activities. This would represent only a minor supplementary investment in time and firewood. These results have broad implications for the discussion about technological evolution and the acquisition of specialised knowledge in the MSA.     

POWER AND INFLUENCE IN THE LATE STONE AGE. A DISCUSSION OF THE INTERPRETATION OF THE FLINT DAGGER MATERIAL

Summary. In this study, the flint daggers in three areas on the Swedish West Coast are used to show the connection between powerful and influential groups and warlike activities. The variations within the flint dagger material are interpreted in terms of social status and the current flint dagger typology is rejected.     

MICROSTRUCTURE OF FLINT AND OTHER CHERT RAW MATERIALS*

The crystallite size, microstrain, stacking disorder and moganite content of flint and other chert raw materials were studied by X‐ray powder diffraction profile analysis. The broadening of the X‐ray reflections of all microfibrous quartz varieties is due to both anisotropic small crystallite size and anisotropic microstrain. The microstructure varies for samples of different origin. The moganite content and the number of structural defects are higher in flint than in older chert and petrified wood. The X‐ray diffraction pattern of the cortex of flint differs from that of the core material, whereas those of the patina and the unweathered interior of the rocks do not.     

IS THE MACROSCOPIC CLASSIFICATION OF FLINT USEFUL? A PETROARCHAEOLOGICAL ANALYSIS AND CHARACTERIZATION OF FLINT RAW MATERIALS FROM THE IBERIAN NEOLITHIC MINE OF CASA MONTERO*

Casa Montero is a mining complex located outside Madrid (Spain), dated from the Early Neolithic (c. 5400–5000 cal bc ). An area of some 4 ha has been investigated and some 4000 shafts recorded, of which 324 have been excavated. The characterization of its raw flint materials and the establishment of its diagnostic features are indispensable in the reconstruction of the distribution of the mine's products beyond the immediate site. This work reports the geological study of the mine's Miocene flint layers and their petrological characterization. Archaeological samples from the mine's shafts were classified according to macroscopic features and petrological characteristics.     

The formation of use-wear polish on flint: beyond the “deposit versus abrasion” controversy

Use-wear polish on flint has previously been attributed to deposition or attrition. Scanning electron microscope observations indicate that some “deposits” are components of the original flint, while other “deposits” result from contact with different materials. The polish seems to be the result of both attrition and a thin layer of amorphous silica.     

First Geochemical ‘Fingerprinting’ of Balkan and Prut Flint from Palaeolithic Romania: Potentials,Limitations and Future Directions

Long‐distance raw material transfers across Romania prior to the Last Glacial Maximum have previously been inferred from either visual and/or petrographic observations of East Carpathian sites. We investigated the potential to ‘fingerprint’ flint from archaeological sites at Mitoc‐Malu Galben and Bistricioara–Lut?rie III in Eastern Romania, using in situ high‐precision analyses of 28 major, minor and trace elements determined by laser ablation – inductively coupled plasma – mass spectrometry (LA–ICP–MS) in combination with multivariate statistical analysis. Our results suggest that geochemical analyses have the ability to distinguish between different geographical sources but are unable to positively associate flint artefacts from archaeological contexts to these geochemical groups. The mismatches of signatures between artefacts and geological materials, however, raise new questions and open unforeseen perspectives.     

THE CHEMICAL COMPOSITION OF SOME ARCHAEOLOGICALLY SIGNIFICANT FLINT FROM DENMARK AND SWEDEN

Flint was one of the most widely employed raw materials for artefact manufacture in Denmark and Sweden during the Stone Age, and it continued to be used during subsequent periods. Prehistoric flint mining and lithic manufacturing studies in these countries have attracted considerable attention, but there have been no recent attempts to chemically characterize the geological source materials. This paper builds on a pilot study ( Hughes et al. 2010 ) and uses energy‐dispersive X‐ray fluorescence (EDXRF) analysis to determine quantitative composition estimates for nine major, minor and certain trace elements in seven archaeologically significant flint sources in Denmark and Sweden, along with new data on a number of other sources of prehistoric significance. These data provide a geochemical foundation for ongoing research devoted to determining contrasts and continuities in the time and space utilization of flint sources in Scandinavian prehistory.
