Organized waste disposal in the Pottery Neolithic: A bifacial workshop refuse pit at Ein Zippori,Israel

A unique Pottery Neolithic context corresponding to the Wadi Rabah culture was found at the multi-layered site of Ein Zippori, Israel. Given the significant amount of flakes, cortical flakes, thinning flakes, and bifacial tool rejects, it was classified as a refuse pit in which bifacial knapping waste from a nearby workshop was disposed. In this paper we present the assemblage of Locus 8071, focusing on the by-products of bifacial tool manufacture and maintenance as well as bifacial tool rejects. We reconstruct the bifacial knapping and maintenance procedures and suggest that Locus 8071 was a disposal area for by-products from a knapping workshop of bifacial tools—an aspect of spatial organization related to possible specialized lithic production at Ein Zippori during the Neolithic period.     

Experimental production of bending and radial flake fractures and implications for lithic technologies

Bend and radially broken flake tools have been identified in Paleolithic and Paleoindian assemblages, and their presence raises important questions. Were these breaks intentionally produced to serve as tool edges or were broken flakes simply scavenged? More importantly, can we distinguish between intentionally produced breaks and those produced incidentally? Experimental archaeology can help answer these questions. In this paper, three sets of experimentally produced bend and radial flake breaks were compared. Flakes were intentionally broken by percussion, and these breaks were compared to those produced during bifacial core reduction and by flake trampling. The presence of point of impact markers, near ninety degree break angles, and an assemblage with high percentages of bend and radial breaks distinguish intentional fracture from incidental fractures produced during bifacial reduction. High percentages of radial breaks distinguish intentional fracture from trampling. Finally, it may not be possible to identify intentional breaks in a bifacial reduction assemblage severely affected by flake-on-flake trampling.     

The Early Middle Pleistocene Site of Gombore II (Melka Kunture,Upper Awash,Ethiopia) and the Issue of Acheulean Bifacial Shaping Strategies

The Gombore II site dates to circa the Brunhes Matuyama Reversal and is one of the Acheulean localities of the Melka Kunture (Upper Awash, Ethiopia) archaeological complex, known since the 1970s. In 2001, this locality was selected as the site for an Open Air Museum and thus excavated. The excavation area has yielded an abundant Acheulean lithic assemblage manufactured on volcanic raw materials in close association with numerous paleontological remains. A technological analysis was carried out on a fraction of the bifacial tools (bifaces and cleavers) which could be temporarily removed from the displayed surface in the museum. This set of artefacts reveals new data about the bifacial shaping strategies adopted at the beginning of the Middle Pleistocene in Ethiopia. The use of obsidian and the systematic manufacturing of twisted bifaces are original features of the assemblage. These data are discussed in the framework of penecontemporaneous East African sites.     

Ontogenetic scaling and lithic systematics: method and application

Stone tools tend to be classified according to a mix of functional, morphological, and technological attributes. This practice results in confusions when large-scale assemblage comparisons are made with the aim of investigating phylogenetic relationships, as functional and cultural information is aggregated. It is argued here that functional criteria must be assessed separately, and that resharpening, as a uniform, repeated, conscious behavioral process of tool maintenance that indexes use and function, can provide a solution to this problem. The subject of this article is a quantitative method for extracting and comparing resharpening trajectories. The method is an adaptation of ontogenetic scaling methods from biology, and is based on obtaining a mathematical representation of shape and size, and finding a relationship between the two. Elliptical Fourier analysis is applied to stone tool contours in order to extract shape information, and then a series of regressions of shape on size provide trajectory vectors. The angles between these are then calculated and subjected to a variety of multivariate statistical tests. A case study involving several European Middle Paleolithic bifacial and unifacial tool assemblages is presented. The results show that resharpening and maintenance can be independent of morphology and technology, suggesting that there are strong grounds for focusing on functional systematics separately.     

Measuring skill in the production of bifacial pressure flaked points: a multivariate approach using the flip-test

Skill is an aspect of prehistoric technology that can inform us on many areas of investigation. This article discusses the notion of skill in prehistoric contexts and how skill is to be formally defined in relation to lithic bifacial tools. The nature of bifacial manufacture entails simultaneous attention to the facial, profile- and cross- section morphology of the core, since each flake removal affects all features. It is argued that bifacial skill can be measured using a multivariate approach, which takes all these features into account. An index measure, the “Bifacial Skill Score”, is proposed and evaluated using both experimental and archaeological data. This measure is argued to constitute a good proxy for skill in bifacial technology and a useful tool for comparative research.     

Jebel Kareem (TH.68): Techno-typological characteristics of a distinctive lithic assemblage from Dhofar,southern Oman

The lithic sample from TH.68 in Southern Oman is characterised by a set of techno-typological features: (a) the variety of blank production strategies employed to produce flakes, blades and bladelets; (b) the level of standardisation of tools, including backed bladelets, end scrapers, burins on truncation, unifacial and bifacial plano-convex points, etc.; and (c) a previously unknown technique that produced specific flakes presenting uniform morphological traits and high incidence of retouch. Here a comprehensive account of the lithic production systems employed by prehistoric human bands and the formal retouched tools that they made is provided.     

Worked Human Femur from Gohar Tepe,Iran

A simple tool made from a gracile human femoral shaft was retrieved from a small animal bone assemblage found in a Late Bronze Age stratum at Gohar Tepe, Iran. The specimen has been identified as a chisel or gouge for which no analogous examples are known in the Near East. Studies examining similar tools from other regions suggest that such a tool may have been used for wood processing or pottery smoothing. Copyright © 2012 John Wiley & Sons, Ltd.     

A new Arabian stone tool assemblage and notes on the Aterian industry of North Africa

An unusual stone tool assemblage, reported for the first time in the Arabian Peninsula, occurs at the southwest edge of the Rub'al Khali desert. The assemblage is characterized by large, unifacially worked, prominently tanged points and scrapers. An age of between about 20,000 and 35,000 years B.P., when the Rub'al Khali was a well-watered grassland, is likely. Typological affinity with the Aterian stone tool industry of North Africa is suggested. Aterian toolmakers were a vigorous population of desert hunters, ranging over much of North Africa and the Sahara during a wet phase of the late Pleistocene. Pursuit of animals running in herds may have been a hunting strategy reflected in some of the Aterian and Arabian tools. Typology of the tanged tools and the palaeogeographic context in which they occur suggest certain specific functional usage.     

Geochemical discrimination of basaltic sources as a tool for provenance analyses of bifacial tools in the southern Levant: first results from the Jezreel Valley,Israel

The determination of groundstone tool sources bears the potential to examine aspects like raw material selection and preference, mobility, trade and exchange patterns, control over resources and long term use of raw material sources. The discovery of the Neolithic/Chalcolithic basanite bifacial quarry of Giv'at Kipod in the Jezreel Valley, Israel, provides the opportunity of raw material centred provenance studies of bifacials in the southern Levant. The basis for reliable provenance analyses is a clear geochemical characterization of the extraction site and its discrimination from other potential sources. To achieve this, the Miocene magmatic rocks of the Jezreel Valley were sampled and analysed by XRF and La-ICP-MS. The geochemical evaluation, combined with cluster analyses, resulted in a clear discrimination of the Giv'at Kipod lava from other basaltic sources in the area. Based on the geochemical field data, a Giv'at Kipod provenance for six bifacial tools found in three archaeological sites dated to the Neolithic and the Chalcolithic periods was established. The results suggest that the quarry was in use for several millennia. This pilot study demonstrates that for provenance analyses lava outcrops in the southern Levant can be geochemically discriminated from each other on a very small spatial scale, on the basis of a detailed field sampling and the application of multivariate methods.     

An Examination of Terminal Archaic Bone and Antler Implements from the Firehouse Site,Dearborn County,Indiana

The Firehouse site (12D563) is a Terminal Archaic Riverton culture site located on a bluff overlooking the confluence of the Ohio and Great Miami Rivers in Dearborn County, Indiana. Excavations at the site in 2003 and 2004 yielded a highly diverse assemblage of around 300 bone and antler implements. Such large assemblages of organic tools are rare outside of wet sites, rockshelters, and shell middens and provide a unique opportunity for the study of tool forms not typically recovered in the Midwest. A typological analysis of the Firehouse assemblage indicates some similarities between these tools and Riverton culture bone and antler implements from the type sites in Illinois. Additionally, a microscopic analysis of manufacturing microtraces indicates that most tools were made using a lithic shaving (rather than an abrasion) technique.     

Points and convergent tools in the European Early Middle Palaeolithic site of Payre (SE,France)

The lithic assemblage from the Middle Palaeolithic site of Payre (Rhone Valley, France) contains a large number of convergent tools and pointed tools of various shapes, sizes and retouch types. These were excavated from several archaeological units, dating from marine isotopic stages 8–5, which also yielded human skeletal remains. Consideration of this large tool kit has led to an improved analysis of Middle Palaeolithic tools with two retouched convergent edges. The 350 tools were not described within the classical typological framework, but, rather, from a lithic technological perspective in relation to a discoid debitage. In addition, an initial macroscopic use-wear analysis aided in establishing whether they were used according to their technical and/or morphological features. The Middle Palaeolithic convergent tools from Payre are shown to be quite diversified, and the question of the significance of the retouch and the definition of the various types is addressed. Initial functional results indicate that a clear relationship between shape and function cannot be easily established, and that these tools were used as hand tools. This study contributes to the debate on the use of stone tip spears in the Early European Middle Palaeolithic.     

A Novel Application of Molecular Techniques to Pacific Archaeofish Remains*

Until recently, the identification of fish bone from Pacific archaeological sites generally relied upon morphological analysis of a relatively restricted number of skeletal elements. Limited morphological variation within fish families, amongst other things, has often restricted Pacific archaeofish determinations to the level of family or, in some cases, genus. We suggest that these relatively imprecise determinations may mask important aspects of prehistoric human fishing practices and subsistence patterns. This paper describes a molecular technique that allows for more precise taxonomic determinations, initially applied to the large and diverse family of Serranidae. The technique involves extraction, amplification, sequencing and analysis of mitochondrial DNA variation in the 16s ribosomal RNA gene. Following development of protocols and primers for modern reference materials, the technique was applied to an archaeological faunal assemblage from Aitutaki, southern Cook Islands.     

What novice knappers have to learn to become expert stone toolmakers

The aim of this paper was to determine what technical gestures must be learned in order to produce stone tools. To identify these gestures, we compared the performance of expert knappers and complete novices. We hypothesised that the differences between novices and experts would indicate which technical gestures experts had learned to successfully produce stone tools. Participants were video recorded while attempting to produce a crude handaxe. The recordings were analysed according to ethological methods used to study animal and human behaviour. The knapping performance of each participant was segmented and scored into units in order to identify the technical gestures being used. The results showed considerable differences between experts and novices in three technical gestures: the type of percussion support, the position of the blank and the angle of blow. Therefore, these three technical gestures appear to be crucial in learning to knap stone at the level of bifacial stone toolmakers. By studying how modern knappers gradually master these three technical gestures we may begin to understand how stone knapping is acquired, how bifacial stone tools emerged and what cognitive challenges early handaxe makers had to face.     

Changing patterns of carnivore modification in a landscape bone assemblage, Amboseli Park, Kenya

This study compares the landscape-scale taphonomic signal of carnivore modification to the surficial bone assemblage in Amboseli Park, Kenya as it was in 1975 and 2002–2004. Change in predator abundances over time provides a means of assessing the taphonomic signal of carnivore-mediated bone consumption and destruction under differing ecological conditions and varying levels of conspecific competition for resources. The landscape assemblage indicates taxonomic variation in the patterning of carnivore modification to ungulates of different size classes as well as within equivalent size classes. Analyses of long bone elements indicate that the differential destruction of limb ends and the strength of the correlation between limb end abundance and bone mineral density provide an indication of the intensity of carnivore modification to a faunal assemblage. The ability to infer levels of carnivore modification based on limb elements can provide faunal analysts with the tools to determine whether the taphonomic signals in the fossil record relate to carnivore modification, hominin transport of appendicular elements, or both.     

An Index of Invasiveness for the Measurement of Unifacial and Bifacial Retouch: A Theoretical,Experimental and Archaeological Verification

Archaeologists are increasingly in need of quantitative measures of stone artefact retouch. Existing techniques fail to provide a generic measure of retouching for all chipped stone artefacts. A fast and reliable index is proposed which measures retouch in terms of the invasiveness of flake scars on the surfaces of complete stone artefacts. Unlike other measures, the index of invasiveness is well suited to the analysis of bifacially worked artefacts such as bifacial points and bifaces. Experimental tests demonstrate a strong correlation between the index and measures of reduction based on diminishing flake weight and numbers of retouch blows. Inter-observer reliability is also demonstrated through the use of a blind test. Limitations of the method are discussed, although potential techniques for surmounting problems are identified. An archaeological application of the index demonstrates the utility of the method in the context of regional assemblage variability in northern Australia.

Wadi Suq and Iron Age period ceramics from Sharm, Fujairah (U.A.E.)

The Wadi Suq period and Iron Age ceramics from Sharm are examined in terms of morphological, compositional and decorative features. The assemblage is typical of the second- and first-millennium BC ceramics of southeastern Arabia. The more unusual Iron Age 'imitation soft stone' ceramics are amply represented and the Sharm assemblage considerably expands upon this corpus of ceramics which has hitherto been less than abundant in the region. Comparisons with other second- and first-millennium sites suggest the tombs were largely occupied in the late Wadi Suq period, a pattern of occupation which again peaked in the Iron Age II period.     

Assemblage variability and bifacial points in the lowermost Sibudan layers at Sibudu,South Africa

Building on the important work of Lyn Wadley at Sibudu, archeologists from the University of Tübingen have excavated the upper stratigraphic units of the Middle Stone Age (MSA) sequence down to the Howiesons Poort (HP). Here, we present the main results from lithic analyses of the lowest part of the Sibudan sequence to assess its overall variability and taxonomic status. Based on the new findings, we also discuss the implications for archeological systematics and the cultural evolution of modern humans in MIS 3 from a more general perspective. The Sibudan deposits encompass over 20 archeological horizons that span a 1.2-m-thick, well-stratified sequence whose base and top have been dated to ～58 ka (MIS 3). In contrast to the upper stratigraphic units, the lower Sibudan assemblages that we analyzed here show much higher use of local sandstone, quartz, and quartzite. These older units are characterized by frequent use of expedient core reduction methods, bipolar reduction of locally available quartz and quartzite, less retouch of blanks, and lower find densities. Tongati and Ndwedwe tools, which feature abundantly in the upper part of the Sibudan sequence, are entirely absent, as are unifacial points. Instead, notched and denticulated tools are common. Surprisingly, knappers manufactured small bifacial points, mainly made from quartz, by means of alternating shaping in the course of the oldest occupations. The results highlight the great diversity of human technological behavior over even short periods during the MSA, raising important questions about the mechanisms of behavioral change, cultural taxonomy, appropriate scales of lithic analyses, and the relationship between the HP and the Sibudan. Our findings further erode the old idea that bifacial technology in southern Africa is limited to the Still Bay. Research is increasingly showing that bifacial points come and go in different forms and contexts of African Late Pleistocene technology, impeding their use as chrono-cultural markers.     

Insights into early Middle Palaeolithic tool use and hafting in Western Europe. The functional analysis of level IIa of the early Middle Palaeolithic site of Biache-Saint-Vaast (France)

Results are presented from the functional analysis of a large selection of tools from level IIa of the early Middle Palaeolithic site of Biache-St-Vaast (France). Results indicate that the site represents a hunting stand with a strong focus on hunting and animal processing activities, next to a maintenance component that appears to concern retooling and repair activities in preparation of the hunting episode(s). In spite of the site's age, a large part of the tool assemblage proves to have been used while hafted. Expertise in hafting was even quite elaborate in the sense that it includes tools for which hafting is not essential. It confirms the importance of hafting studies for improving insights into assemblage variability and past human behaviour.
