Technological,Functional and Contextual Aspects of the K2 and Mapungubwe Worked Bone Industries

Mapungubwe (AD 1220–1290) is generally regarded as the first urban centre in southern Africa, functioning as the seat of power for an extensive but short-lived polity. More than 80 years of excavations here, and at its nearby predecessor K2 (c. AD 1000–1220), resulted in a substantial assemblage of material remains from elite and commoner contexts. This assemblage includes a large collection of worked bone objects, such as needles, awls, tubes and objects of personal adornment. Of particular interest are the bone arrowheads and link-shafts, of which a significant number of specimens were found complete and intact. Such quantities of well-preserved worked bone objects are unique in the archaeological record of the region. The worked bone assemblages from these two sites provide a rare opportunity to study multiple components of the production process as well as the use context of bone objects. In this paper, we characterise the K2 and Mapungubwe worked bone industries through various morphological, technological, use-trace and contextual approaches and discuss the significance of these aspects in terms of raw material selection and manufacture and archaeological use context. In particular, this study shows the complexity of these worked bone industries over time.     

MULTIANALYTICAL STUDY OF PALAEOLITHIC REINDEER ANTLER. DISCOVERY OF ANTLER TRACES IN LASCAUX PIGMENTS BY TEM*

Palaeolithic and modern reindeer antler were analysed using complementary techniques to evaluate the conservation state of bone material. X‐ray diffraction, FT‐IR spectroscopy, scanning electron microscopy (SEM–EDX) and transmission electron microscopy (TEM–EDX) as well as proton induced X‐ray and γ‐ray emission (PIXE–PIGE) at the particle accelerator AGLAE, C2RMF were applied. This study enabled us to define the chemical and structural features of ancient antler at the micro‐ and nanometre scale and compare them to those of other bone materials such as bone and ivory. Antler is richer in its organic fraction compared to bone and ivory. Its mineral fraction, carbonated hydroxylapatite, shows very specific crystal shapes at the nanometre scale. This specific property allowed us to recognize antler traces in pigment samples originating from rock art paintings in the Lascaux cave, Dordogne, southwestern France, Magdalenian period. Therefore, TEM–EDX is the technique of choice for characterizing antler traces in complex mixtures. In the paint material of Lascaux, antler seems most likely to be a pollutant introduced either by stirring the pigments in water with a piece of antler or by carving antler artefacts next to the preparation of paint material. However, it could eventually be used as a marker of paintings that were created contemporaneously.     

LA VIE SOCIALE DE L'ART MOBILIER PALÉOLITHIQUE. MANIPULATION, TRANSPORT, SUSPENSION DES OBJETS ON OS, BOIS DE CERVIDÉS, IVOIRE

Summary: It has been suggested that some Palaeolithic objects show traces of long-term handling, suspension or transport. However, no criteria have been established for identifying such traces and differentiating them from other traces of natural or human origin. Handling, suspension, polishing with skin and transport of bone, antler and ivory objects have been reproduced experimentally and observed by optical microscopy and SEM. the width of striations seems to be the only criterion for differentiating handling, suspension and polishing. the transport of a single bone object in a leather bag produces striations of different dimensions to those produced by handling. the differentiation between traces of transport and those due to polishing with skin are more problematic. the transport of several bone objects in the same bag results in traces that differ according to the morphology and the hardness of the objects accompanying them. In particular, the pits generated by knocking against each other enable one to identify the nature of the other objects. Finally, analyses of bone objects known to have been subjected to long-term handling and archaeological objects dating from the Solutrean and Magdalenian cultures were compared with the experimental results.     

The Middle Palaeolithic of the Nejd,Saudi Arabia

The Pleistocene archaeological record of the Arabian Peninsula is increasingly recognized as being of great importance for resolving some of the major debates in hominin evolutionary studies. Though there has been an acceleration in the rate of fieldwork and discovery of archaeological sites in recent years, little is known about hominin occupations in the Pleistocene over vast areas of Arabia. Here we report on the identification of five new Middle Palaeolithic sites from the Nejd of central Arabia and the southern margins of the Nefud Desert to the north. The importance of these sites centers on their diversity in terms of landscape positions, raw materials used for lithic manufacture, and core reduction methods. Our findings indicate multiple hominin dispersals into Arabia and complex subsequent patterns of behavior and demography.     

Whales, Walruses, and Elephants: Artisans in Ivory, Baleen, and Other Skeletal Materials in Seventeenth- and Eighteenth-Century Amsterdam

Hard animal tissues obtained from whales, walruses, and elephants are baleen, whale bone, walrus ivory, walrus baculum, and elephant ivory. Objects of these materials were manufactured by artisans in Amsterdam in the seventeenth and eighteenth centuries. New archaeological and historical evidence show the import and importance if these materials. The importance of baleen is evident from historical sources. Whale bone and walrus penis bone were only used occasionally. The use of walrus ivory appeared to be of minor importance in comparison to elephant ivory. The Dutch elephant ivory trade in the seventeenth and eighteenth centuries is evident in historical and archaeological sources.     

Burin Manufacture and Utilization: An Experimental Study

Abstract

Burins were experimentally manufactured and utilized to differentiate the effects on wear patterns of raw material, method of manufacture, material utilized, and mode of utilization. Differing methods of manufacture and modes of utilization were employed to test the assumed function of burins as being exclusively bone/antler working tools. Results of univariate and multivariate statistical tests are presented along with differentiating characteristics of three methods of manufacture (hard-hammer, soft-hammer, pressure), three types of raw materials (obsidian, basalt, chert), four materials worked (hard and soft wood; dry and soaked bone), and two modes of utilization (graving, scraping).     

Microwear study of quartzite artefacts: preliminary results from the Middle Pleistocene site of Payre (South-eastern France)

Preliminary functional results obtained from the quartzite assemblage of the Early Middle Palaeolithic site of Payre (South-eastern France) are presented. In an area rich in flint, hominins at Payre also collected quartzite in their local environment, specifically along the Rhône River banks. Although the Payre lithic assemblage is largely composed of flint, quartzite was introduced in the site mainly as large cutting tools knapped outside. This fact pointed out an apparently highly differential treatment of the raw material types available in the region. A major concern is to understand the reason why. Is there any functional reason for the introduction of those artefacts, perhaps to perform specific activities related to the toughness of quartzite? Or is there any functional differentiation among the various raw materials? Use-wear analysis is a useful tool for better understanding human technological choices and strategies of lithic raw material management. Before attempting to extensively apply use-wear analysis on the quartzite assemblage, we analysed a limited sample to evaluate the general surface preservation. A specific experimental programme with the same local quartzite was carried out in order to provide a reliable comparative reference for interpreting use-wear evidence on archaeological implements. Methodological difficulties related to use-wear analysis applied to quartzite artefacts are also discussed. Both Optical light microscopy (OLM) and Scanning Electron Microscopy (SEM) were employed in this study; however, interpretations were elaborated considering principally SEM micro-graphs.The analysis of the archaeological material showed a good state of preservation of the surfaces with a low incidence of post-depositional alterations. The documented use-wear allowed us to identify the active edges, the kinematics and, more rarely, the worked material. Chopping activities were documented on two large artefacts suggesting a specific utility of those tools.     

A Palaeolithic fishhook made of ivory and the earliest fishhook tradition in Europe

Prehistoric fishhooks have previously been described in northern Europe as being common since the Mesolithic. Here we present a Final Palaeolithic ivory fishhook from the site Wustermark 22 (north-eastern Germany), the raw material of which is about 19,000 years old. Five further fishhooks were discovered in situ at the same site one of which has a calibrated radiocarbon age of about 12,300 years. The tool industries of flint artefacts and bone/antler tools are associated with descendants of the Federmesser-culture and the palynological context indicates a Younger Dryas environment. Wustermark 22 represents the largest collection of Palaeolithic fishhooks so far found at a single European site. A comparison with other sites in Europe, containing Palaeolithic fishhooks suggests that the appearance and development of fishhooks may be associated with a general change in resource availability during the Greenland Interstadial 1 (Bølling/Allerød warming), which is also connected with a change from late Upper Palaeolithic to Final Palaeolithic industries in Northern Central Europe. We conclude that Mesolithic fishhook tradition has its roots in the Final Palaeolithic.     

Defining and Characterizing Archaeological Quartzite: Sedimentary and Metamorphic Processes in the Lithic Assemblages of El Habario and El Arteu (Cantabrian Mountains,Northern Spain)

Quartzite was the second most‐often used lithic raw material in Europe in the Palaeolithic. However, this rock has not been characterized fully from the geo‐archaeological point of view. This study characterizes, defines and determines types of quartzite in northern Spain through a methodology that integrates petrography, digital image processing and X‐ray fluorescence. As a methodological foundation for the characterization of the material, it aims to open the possibility of discovering mechanisms of mobility, selection and management of quartzite by prehistoric societies. The types determined, based on the petrogenesis of the material, enable a better understanding of the archaeological sites of El Arteu and El Habario in the context of northern Spain in the Middle Palaeolithic.     

The Definition of Spatial Units in Middle Palaeolithic Sites: The Hearth-Related Assemblages

This paper deals with hearth-related accumulations in Middle Palaeolithic sites. Spatial behaviour is a key to understanding the cultural capabilities of ancient hominids. Ethnoarchaeological and archaeological research has shown that hearth-related assemblages are a basic feature in the spatial behaviour of modern and prehistoric hunter–gatherers. In this paper, we propose a methodology for analysing archaeological accumulations and study a series of hearth-related assemblages from the Abric Romanı́ Middle Palaeolithic site (Capellades, Spain). We also analyse the degree of contemporaneity between the different activity episodes documented at each archaeological accumulation. Our results suggest that the characteristics of domestic areas in this site are not substantially different from those observed in ethnoarchaeological contexts and Upper Palaeolithic sites.     

The Source Provenance of Bronze Age and Roman pottery from Cyprus

Archaeological interpretations of ancient economies have been strengthened by chemical analyses of ceramics, which provide the clearest evidence for economic activity, and comprise both the objects of exchange and its means. Pottery is often manufactured from local materials, but its compositional diversity typically prevents significant patterns of resource utilization from being identified. Centrally located and positioned on traditional shipping routes, Cyprus maintained ties with and supplied a variety of distinctive ceramic products to the major commercial centres in the eastern Mediterranean throughout Antiquity. We analysed two Cypriot .ne wares and a variety of utilitarian pottery, as well as samples of extant Cypriot clays to determine source provenance. These chemical analyses provide an objective indication of the origins of ancient (Bronze Age and Roman) ceramics manufactured on Cyprus. The distribution of the probable clay sources and the links between pottery style and the material environment also afford a perspective on the spatial organization of large‐scale pottery production on the island. Compositional analysis provides the means to assemble geographies of pottery production and to unravel the interregional system of exchange that operated in Antiquity, but the ability to accomplish these tasks is predicated on systematic analyses of ceramic products and raw materials that are found far beyond the bounds of individual archaeological sites.     

Investigating experimental knapping damage on an antler hammer: a pilot-study using high-resolution imaging and analytical techniques

Organic (bone, antler, wood) knapping tools were undoubtedly a component of early human tool kits since the Lower Palaeolithic. Previous studies have identified pitting and the occasional presence of embedded flint flakes as important features for recognizing archaeological bone and antler percussors. However, no systematic protocol of analysis has been suggested for the study of this rare archaeological material. Here we present qualitative and quantitative results of a preliminary analysis of an experimental knapping hammer, using a novel combination of microscopy (focus variation optical microscope and scanning electron microscope), micro-CT scanning and energy dispersive X-ray spectroscopy. These imaging and analytical techniques are used to characterize use-damage from the manufacture of handaxes. This paper highlights the strengths and weakness of each technique. Use-wear on the working area included attritional bone loss, micro-striations and compaction of the outer layer of the antler matrix from repeated hitting of the beam against the sharp edge of the handaxe during knapping. Embedded flint flakes were also identified in the pits and grooves. This combination of high-resolution imaging techniques is applicable to fragile archaeological specimens, including those encrusted by sediment or encased in matrix.     

Selinunte (Sicily) and its productive context: the clayey raw materials applied in a long-lived ceramic production (seventh to third century BCE)

The westernmost of the Greek-Sicilian towns, Selinunte, founded in western Sicily during the second half of the seventh century BCE, gives amazing evidences of a historic activity of ceramic production (seventh to third century BCE). The present study aims to identify the raw materials available in the vicinity of the archaeological site of Selinunte, which were possibly used by the ancient potters, and to characterise them by means of petrographic and chemical techniques. A sampling campaign of clays and sands for tempering was undertaken in the archaeological site and the adjacent area. Moreover, locally produced archaeological bricks and tiles were considered helpful for comparison regarding the definition of local ceramic macro- and micro-fabrics and were analysed as well. The comparison between textural, mineralogical and chemical data allowed us to highlight a good similarity between the clayey materials available in the area and the local ancient bricks and tiles. Their compositional resemblance suggests the hypothesis of a systematic use of the studied clays for ceramic productions from the Archaic to the Hellenistic period. The preliminary archaeometric results obtained so far could enhance the distinction between local manufactures and imports and may well lead to the identification of ceramic artefacts produced by the Archaic-Hellenistic workshops of Selinunte at various consumption sites.     

Aurignacian ethno-linguistic geography of Europe revealed by personal ornaments

Our knowledge of the migration routes of the first anatomically modern populations colonising the European territory at the beginning of the Upper Palaeolithic, of their degree of biological, linguistic, and cultural diversity, and of the nature of their contacts with local Neanderthals, is still vague. Ethnographic studies indicate that of the different components of the material culture that survive in the archaeological record, personal ornaments are among those that best reflect the ethno-linguistic diversity of human groups. The ethnic dimension of beadwork is conveyed through the use of distinct bead types as well as by particular combinations and arrangements on the body of bead types shared with one or more neighbouring groups. One would expect these variants to leave detectable traces in the archaeological record. To explore the potential of this approach, we recorded the occurrence of 157 bead types at 98 European Aurignacian sites. Seriation, correspondence, and GIS analyses of this database identify a definite cline sweeping counter-clockwise from the Northern Plains to the Eastern Alps via Western and Southern Europe through fourteen geographically cohesive sets of sites. The sets most distant from each other include Aurignacian sites from the Rhône valley, Italy, Greece and Austria on the one hand, and sites from Northern Europe, on the other. These two macro-sets do not share any bead types. Both are characterised by particular bead types and share personal ornaments with the intermediate macro-set, composed of sites from Western France, Spain, and Southern France. We argue that this pattern, which is not explained by chronological differences between sites or by differences in raw material availability, reflects the ethnolinguistic diversity of the earliest Upper Palaeolithic populations of Europe.     

Application of 3-dimensional microscopy and micro-CT scanning to the analysis of Magdalenian portable art on bone and antler

The appearance of portable artistic objects during the Upper Palaeolithic is characterised by a combination of a wide choice of techniques, use of different materials and a diversity of iconographic expression, with many objects made of bone and antler decorated with animal representations. Taphonomic and experimental approaches have been systematically applied in an effort to understand the technical and artistic procedures followed. In this study, we applied a new combination of 3-dimensional microscopy (focus variation optical microscope) and micro-CT scanning to the analysis of two Magdalenian engraved specimens: a reindeer antler from the site of Neschers (France), engraved with the partial image of a horse in left profile, and a horse metatarsal from Courbet Cave, Penne (France), engraved with a horse head also in left profile. Results of the analysis suggest that both the Neschers and Courbet Cave engravings had been prepared before being carved. The overall contours of the horse body/head were incised first, while anatomical features were added afterwards. In the Neschers case, the incision resulted from the repeated scratching of a previously made incision in order to enlarge the engraving, possibly reflecting the engraver's aesthetic sense. The combination of the techniques used in this study is applicable to fragile or unique archaeological specimens. Micro-CT scanning, in particular, provides non-invasive means for identifying engravings that are obscured by encrusted sediment. The application of these techniques can potentially open new avenues for the authentication, technical and gestural recognition and interpretation of incised forms and artistic creativity.     

NO STONE UNBURNED: A COMPOSITIONAL ANALYSIS OF OBSIDIAN MICRODEBITAGE BY LASER ABLATION TOF–ICP–MS

Obsidian is an effective material for the study of prehistoric raw material use and exchange, due to the high degree of homogeneity and redundancy of obsidian materials and manufactured objects in the archaeological record. The destructive nature of many analytical techniques often impedes compositional research because of the damage that may occur to priceless archaeological artefacts. The combination of time‐of‐flight (TOF) ICP–MS with a laser ablation sample introduction system provides a highly efficient means of chemically characterizing obsidian. This study shows that sample size limit capabilities of TOF–ICP–MS analysis of obsidian can reach less than 100 μm. Sampling and analysis of microartefacts enables researchers to overcome problems of sampling bias with very little damage to the valuable existing materials within the archaeological record and expands the potential for chemical compositional analyses in archaeology.

Interpreting elements and isotopes in glass: A review

Substantial databases of elemental and isotopic analyses of ancient glass exist and are used to investigate raw material origin, trade, exchange, and processes such as mixing and recycling. However, the chemistry of archaeological glass may be challenging to the untrained. The paper provides structured information on the origin of chemical elements and their isotopes in ancient glass. It details some of the functions of individual elements in the glass and from which raw material(s) or process(es) they originate.     

Magdalenian Children: Projectile Points,Portable Art and Playthings

Children, no doubt, were a significant component of Upper Palaeolithic societies. Despite this fact, however, serious identification and consideration of material culture which may have belonged to children – at least at one time during their use‐life – have not been undertaken. This situation extends to the best represented and most intensively studied of the European Palaeolithic techno‐complexes, the Magdalenian (c.21,000–14,000 cal BP), and consequently, we know very little about the children of this enigmatic people. As play, including object play, is a ‘true cultural universal’, we can be certain that Magdalenian children integrated objects into their games, with these playthings later incorporated into the archaeological record. Through examining ethnographic accounts of recent hunter‐gatherer children and reconsidering archaeological assemblages in light of these data, this paper suggests that Magdalenian playthings probably included full‐sized adult weapon tips and – more significantly – pieces of what archaeologists term ‘art mobilier’.     

Refining the definition of cultural levels at Karabi Tamchin: a quantitative approach to vertical intra-site spatial analysis

The visual identification of archaeological levels can be difficult when stratigraphy is complex. This study emphasizes the importance of three-dimensional intra-site spatial analysis as a means of testing the integrity of archaeological levels, including the identification of palimpsest deposits. A geographical information system (GIS) is applied to a three-dimensional spatial analysis of lithic and bone distributions from Karabi Tamchin, a Middle Palaeolithic site from the Crimea, Ukraine. K-means statistical clustering is combined with a series of data transformations to identify and interpret the vertical and horizontal spatial organization of the site. The results indicate that K-means cluster analysis, used in conjunction with GIS, provides an exceptional method of identifying discrete clusters of archaeological materials in three dimensions. Through an analysis of cluster contents within levels, it is possible to reconstruct and compare patterns of spatial organization at Karabi Tamchin, contributing to current debates regarding the cognitive complexity of Neanderthal populations.
