Lithic refitting and movement connections: the NW area of level TD10-1 at the Gran Dolina site (Sierra de Atapuerca,Burgos, Spain)

The first lithic refit studies were carried out at the end of 19th century, but the method was not considered an area of real interest to archaeology until quite recently. Today, lithic refitting is applied in a multitude of areas of enquiry including lithic technology, intra-site and inter-site spatial distribution, archaeostratigraphy and formation processes. In this paper, we present a refit study of the lithic materials recovered in the base of the NW sector of level TD10 at the site of Gran Dolina (Sierra de Atapuerca, Spain). We aim to provide information about spatial distribution through identifying activity areas and the internal connections between those areas. Our work resulted in various refits whose connections reveal the movements of the pieces and/or knappers that once occupied the site. Our results also show the importance of studying the set of materials as a whole and the bias involved in analyzing only a small sample. The refits, connections and directions of movement allow us to infer areas in which an activity took place, but these results must be confirmed in future works covering the entire lithic assemblage of TD10.     

Life at the end of the Holocene moist phase in south‐east Arabia — the Late Neolithic site of Jebel Thanais 1 (JTH1)

The surface site of Jebel Thanais 1 is located in the Emirate of Sharjah (U.A.E.) at the western flank of the Jebel Faya/Jebel Buhais anticline structure. A dense scatter of lithic artefacts and fireplaces indicates Stone Age settlement activities in this area. Radiocarbon dates obtained from fireplaces date the occupation of the site to both the beginning and the very end of the fifth millennium cal. BC. During the second half of the fifth millennium the deterioration of climatic conditions in south‐east Arabia had a noticeable impact on settlement patterns and subsistence strategies. While coastal habitation sites from this time are well known along the shores of the Oman peninsula, only a few poorly dated sites allow insights into habitation and raw material procurement strategies and lithic technology in the interior. Investigations into the spatial structure of the site and an analysis of lithic finds will contribute to a better understanding of this period.     

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.     

Thermally Altered Novaculite and Stone Tool Manufacturing Techniques

Abstract

This paper describes a study of the physical origins of improved flaking properties, called flakeability, for novaculite, a material exploited for stone tool manufacture by the peoples of prehistoric Arkansas, Missouri, Texas, and Louisiana. Experimentation in thermal pretreatment and ways to detect and discriminate the results of this pretreatment were carried out. The criteria derived for distinguishing this alteration in the novaculite are easily determined by a straightforward analysis that can be done in almost any laboratory.

The results of this experimentation have direct implications for the study and identification of thermal pretreatment in this and other stone materials. From the correlations between the physical alteration of such source materials and the implication for manufacturing techniques, the archeologist can more validly infer relationships between prehistoric lithic technology and the knappers who developed highly diversified and specialized techniques. Such experiments combined with wear analysis, material source determination, and other lithic studies will allow the archeologist to delineate manufacturing and exploitative patterns and examine their relationship to all forms of cultural and environmental variables.     

Blank Concerns: Issues of Skill and Consistency in the Replication of Scottish Later Mesolithic Blades

Skill is central to the identification of the individual within lithic analysis. Modern replication tends to focus on the proficient flintknapper, and emphasises complex, technically demanding implements and high quality raw materials. Yet, acquiring lithic skill is a universal process that manifests itself in various ways depending on technological strategy and raw material. This paper presents the results of a programme of experimental replication that explores notions of consistency and identity. Based on Mesolithic blade technology, using direct percussion reduction and variable pebble resources, it compares knappers with different experience and identifies some salient parameters of individual performance.     

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.     

Native Californians at the Presidio of San Francisco: Analysis of Lithic Specimens from El Polín Spring

Relatively few archaeological studies have examined the experiences of native people at Spanish colonial military installations. A small flaked lithic assemblage at the Presidio of San Francisco provides insight into the lives and labor of Native Californians there. Technically proficient knappers, making do with poor-quality, locally available material, engaged in freehand core reduction and produced non-symmetrical, bifacially flaked tools through percussion production. These tools were most likely used for cutting during specific tasks. The analysis reveals how Native Californians in colonial institutions maintained flintknapping traditions in social spaces that were likely shared by native people and colonists.     

Neandertal Behavior at the Middle Palaeolithic Site of Abric Romaní, Capellades,Spain

Abstract

This paper synthesizes the work carried out since 1983 at the Middle Palaeolithic site of Abric Romaní, Spain, reconstructing Neandertal behavioral and settlement patterns. The sedimentary features of this site give a high resolution of prehistoric occupational events. Large surface excavation (over 300 sq m) has been used to obtain a detailed picture of intrasite settlement patterns. The reconstruction of activities and their spatial and temporal organization is a key issue in the debate concerning the cultural capabilities of Neandertals versus anatomically modern human beings, and our interpretation integrates geoarchaeology, lithic technology, taphonomy, zooarchaeology, and anthropology. In this way, we explain the degree of diversity within a single Neandertal archaeological site, especially regarding lithic assemblage variability, faunal processing activities, and settlement patterns.     

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.     

The Hogeye Clovis cache,Texas: quantifying lithic reduction signatures

The Hogeye Clovis cache is comprised of 52 late-stage bifaces, finished points, and knife/cores cached in central Texas. Because these artifacts were all likely made and cached approximately 13,000 years ago by one or a handful of knappers belonging to a single band with a shared Clovis cultural template, Hogeye provides a rare opportunity to investigate Clovis lithic reduction signatures. This paper builds on previous analyses and presents new methods for quantifying Clovis biface production signatures, including serial flaking and the timing of last overshot flaking. The results show that the Hogeye cache bifaces technologically and morphologically differ from other regional Clovis biface reduction signatures. Additional data is needed to determine whether these differences reflect individual knapping preferences or regional cultural signatures. The methods used and developed here are not Clovis-specific and could be modified and combined with other analytical techniques to identify reduction signatures in biface assemblages from other times and places.     

Lithic use-wear analysis of the Early Gravettian of Vale Boi (Cape St. Vicente,southern Portugal): insights into human technology and settlement in southwestern Iberia

During the Upper Paleolithic, lithic variability is one of the most important keys to recognize hunter-gatherer behavior, technology, ecology, and social dynamics. The origin and expansion of Gravettian populations in Eurasia has been seen as one of the most critical episodes in human evolution, argued to be the first clear evidence of the so-called polymorphism among modern human populations. In the case of southern Iberian Peninsula, recent data have shown a new regional and diachronic organization for the Gravettian occupation in this region. Therefore, the interpretation of such variability is one of the most important questions, and functional analysis is a fundamental proxy to recognize human technological, settlement and ecological adaptations as major factors for this polymorphism. This study focused on lithic use-wear analysis of the Early Gravettian of Vale Boi (southern Portugal), in order to understand lithic technological organization and variability within and between occupations at the site. Results show similar patterns between assemblages, showing that different materials were worked at the site, although showing reduced time of work, low variability and percentage of pieces used. Unlike other Gravettian contexts in southern Iberia, the Early Gravettian from Vale Boi is characterized by some variability of backed points, marked by the predominance of bipointed double-backed bladelets. Functional analysis of the Early Gravettian lithic industries of Vale Boi provide a new insight to interpret human technology and settlement strategy during the onset of Upper Paleolithic industries in western Eurasia.     

Funeral practices and foodstuff behaviour: What does eat meat mean? Stable isotope analysis of Middle Neolithic populations in the Languedoc region (France)

The aim of this study is to reconstruct the dietary patterns and economic behaviours of Neolithic populations in the Northwestern Mediterranean using isotopic and archaeological data. Burials come from four sites located in Languedoc–Roussillon region in French Mediterranean area. These sites are dated from the Middle Neolithic period (ca. 4500–3500 BC). They represent the Chasséen culture, characterized by regional features, such as economy management, resulting from territorial control. For this investigation, a stable isotopes (δ¹³C and δ¹⁵N) method has been used on 50 human bone collagens and 28 associated animal bones. This method provides direct dietary information on the protein consumed including the relative amounts of marine vs. terrestrial and animal vs. plant proteins in diets. Isotopic results are mainly compared to archaeological data to understand economic distinctions and potential social status variations between different groups using specific funeral practices, i.e. lithic chamber graves vs. domestic/funeral pits. Results show that individuals buried in lithic chamber graves and those buried in pits did not have the same dietary pattern. This result suggests a possible differentiation between two socio-economic groups, i.e. consumers of resources from herding and from farming. No aquatic food appeared to be routinely consumed by these individuals despite a relative close proximity to sea and freshwater sources. Moreover, these outcomes lead us to hypothesize that: (1) funeral practices could be linked to specific economies and/or (2) to different social status and that (3) burial type and foodstuff could be an expression of religious worship. Further research could include data from other areas, such as Spanish Catalonia where there are funeral structures similar to Languedoc lithic chamber graves.     

Evaluating morphological variability in lithic assemblages using 3D models of stone artifacts

Technological and morphological variability in lithic artifacts is commonly used to identify taxonomic entities in Paleolithic research contexts. Assemblages are mainly studied using either linear distance measurements or qualitative assessments of morphologies. Here, we present a method to quantify morphological variability in lithic artifacts using 3D models of stone artifacts. Our study on the sequence of the Upper Paleolithic layers V–I from the site Yabroud II in western Syria, demonstrates that utilizing 3D models provides a new insight into the variability of lithic technologies. We use quantitative data on convexities, twist and scar patterns on cores and blades, attributes previously not readily quantifiable, to trace technological change through the archaeological sequence. We are able to identify differences and translate these findings into a grouping of the layers. While layers VI–II are characterized by technological continuity and were grouped together, layers V and I can be separated from this group and represent technologically different groups chronologically before and after. Our results demonstrate the potential of 3D models for studying morphological variability in lithic assemblages.     

Bladelet cores as weapon tips? Hafting residue identification and micro-wear analysis of three carinated burins from the late Aurignacian of Les Vachons,France

The interpretation of Upper Palaeolithic carinated lithic forms as discarded cores from the production of bladelets is now well established and the weight of evidence to support this indisputable. However, it is also clear that the relationships between lithic typology, technology and function are complex. Presented here are micro-wear analyses of three carinated burins from the late Aurignacian level of Les Vachons, France. The remains of birch pitch adhering to the artefacts are clear evidence that they were hafted; the first time this material has been identified on Aurignacian artefacts. Thus, while the techno-morphology of the artefacts is consistent with their role as bladelet cores our results indicate that they functioned as hafted tools. Unlike other Middle and Upper Palaeolithic industries the Aurignacian is not thought to include (non-bladelet) lithic weapon tips. However, due to patterns of use-wear present on two of the artefacts we suggest that this was their most plausible hafted function.     

Recent developments in the analysis of lithic artifacts

A review of recent research on lithic technology and functional analysis is presented. Our perception of the state of the art is based on a review of the literature published during the past three years and on the topics that were covered at conferences and workshops on lithic analysis. While the goals have essentially remained the same since the turn of the century, concerns with chronology and the classification of lithic artifacts have given way to studies that treat stone implements as products of a dynamic system of human behavior. In order to understand stone artifacts and the people that made and used them, archaeologists must understand theprocesses involved in the acquisition, production, exchange, and consumption of lithic artifacts. In the past ten years, experimental studies involving the manufacturing and use of stone tools have been integrated with studies of refitted or conjoined lithic artifacts and microwear analysis. The result is a much more dynamic view of the variability in assemblages of lithic artifacts. In this review, we focus on replication and technological analysis of chipped stone artifacts and microwear analysis, and consider the implications of this research.     

Using lithic assemblage formation to approach Middle Palaeolithic settlement dynamics: El Salt Stratigraphic Unit X (Alicante,Spain)

The superposition of anthropogenic remains usually results in archaeological palimpsests, hindering an accurate characterization of the behavior underlying such remains. Aimed at facing this methodological constraint in the study of Palaeolithic contexts, we present a contextual approach to Neanderthal settlement dynamics based on an understanding of lithic assemblage formation processes. We focused on a set of lithic artifacts from the Middle Palaeolithic site of El Salt. With the goal of isolating temporally constrained units of behavioral analysis, we analyzed the spatial distribution of lithic, faunal and combustion remains. Then, the lithic records from each of the resulting units were analyzed from a genetic and technical perspective. This goal was achieved by identifying lithic Raw Material Units (RMU) through observations on reduction processes, refits and their spatial distribution. Our results suggest that El Salt SU X lithic remains represent several diachronic human occupation episodes and different site functions. This study illustrates the benefit of investigating lithic assemblage formation processes to alleviate the palimpsest problem in Palaeolithic contexts.     

Stone Tool Production of the Longshan Culture at the Liangchengzhen Site in Rizhao of Shandong

The manufacture of stone tools was one of the most important craft production activities in prehistoric human society. Previously, lack of sound evidence had made it too early to confirm whether or not stone tool production during the Longshan cultural period had already transformed from a primitive self-sufficient household mode of production to a specialized mode of production. Excavation of the site of the Longshan cultural site at Liangchengzhen in Rizhao, Shandong from 1998–2001 through meticulous field methods such as sieving and floatation yielded a large number of lithic reduction tools, ranging from grinding stones, stone hammers, and polishing stones to raw materials, semi-finished products, and lithic debitage of various sizes, resulting from the lithic reduction process. This excavation suggests that the Liangchenzhen site was a settlement site where the complete process of lithic reduction was practiced. Through comparison with contemporary large-scale excavated sites of the Longshan culture, it is suggested that the Area 1 at the Liangchengzhen site was a lithic reduction locality with a relatively high degree of specialization which was used for hundreds of years. It is possible that stone tool production had already advanced to a stage of relatively high specialization during the Longshan cultural period in the Haidai region.     

First Evidence of Collective Human Inhumation from the Cardial Neolithic (Cova Bonica,Barcelona, NE Iberian Peninsula)

Excavations at Cova Bonica (Barcelona, Spain) have revealed 98 human remains, grouped into five age clusters and corresponding to a minimum of six non-articulated individuals. The remains are clearly associated with Cardial pottery, lithic artifacts, and ornaments suggesting an Early Neolithic horizon. The radiocarbon dating of three human individuals provides a reliable attribution to this period, with a range between ca. 5470 and 5220 cal b.c., identifying it as one of the few assemblages of human remains directly dated from this period. These remains correspond to a rare collective human inhumation and join a growing body of samples from the Cardial Neolithic, which is providing some of the important sites for the study of population movement and the spread of Neolithization along the western Mediterranean coast.     

Archaeological Publications

Abstract

A number of lithic studies over the past several years have indicated that average flake weight (size) appears to be a direct reflection of the ease of lithic procurement, with the greater the distance to the lithic source, the smaller the respective general flake size. Similar high-quality lithic materials from Pot Creek Pueblo and the Cerrita pithouse site of the Taos area of the northern Rio Grande Valley in New Mexico provide an excellent basis for the study of the effects of source distance on the metrical attributes of lithic material due to the wide array of local and nonlocal lithic resources available at varying distances from the two settlements and utilized within them. The analysis indicates that flake thickness and volume (flake length × width × thickness) provide statistically significant linear trends and patterns in relation to respective source material distance. The general flake dimensional-decremental trend with increasing source distance probably reflects smaller lithic parent material sizes with increasing material source distance as well as a lithic technology oriented toward greater material conservation and less technological variability as the distance to the respective lithic material source increases.
