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.     

Particle size distribution of lithic assemblages and taphonomy of Palaeolithic sites

Lithic debris derived from knapping and used tools can be assimilated to simple sedimentary particles that may undergo size sorting when exposed to geomorphic processes such as streamflow or overland flow. Sorting can be identified by comparing the size distribution of archaeological assemblages to that of experimental core reduction sequences. A new database including different types of raw material (mainly flint and quartzite) and Palaeolithic debitage (blade, Levallois, discoid, on anvil, and shaping) has been built for this purpose. Palaeoeskimo data have also been added to illustrate microlithic industries. For all the debitages and raw materials, the particle size of knapping products >2 mm in width fits with a power-law distribution and shows only minor fluctuations, the range of which is always <15% between experiments (all steps of the chaîne opératoire included up to the final tool). A lithic assemblage derived from block/core knapping or blank/preform production will display a particle size distribution close to the experimental distributions if not subsequently modified. Modifications may originate either from sedimentary processes or from anthropogenic factors. To help distinguishing amongst these, data on the impact of both water flows on sedimentary particles or experimental assemblages, and anthropogenic processes such as importation-exportation (of core, preforms or finished tools) or uneven spatial distribution of the different steps in core reduction and tool production within a site, are reviewed. By contrast to anthropogenic modifications, sedimentary processes are generally typified by strong impoverishment in or selective accumulation of fine-grained (<10 mm) artefacts together with a low intra-site variability (spatial homogenization) or a downslope size trend. Archaeological case studies taken from French Palaeolithic site are then detailed. Evidence for lithic redistribution implies that care should be taken in archaeological site analysis since sorting may impact significantly the initial techno-typological balance of the assemblage.     

The black layer of Middle Palaeolithic combustion structures. Interpretation and archaeostratigraphic implications

Certain aspects of the formation processes of simple, flat archaeological combustion structures such as those present in the Middle Palaeolithic record remain unexplained. Such kind of combustion structures are commonly affected by postdepositional agents and often, their only distinct, well preserved component is a thin black lens on the ground. Hence, understanding the nature of this black lens is essential towards archaeological interpretation. From an interdisciplinary microstratigraphic approach, we present a case study in which for an entire experimental series of flat combustion structures the black layer represents the fire-altered topsoil on which the fire was made. Parallel analysis of archaeological Middle Palaeolithic combustion structures from the site of El Salt (Alicante, Spain) reveal similar patterns, leading to significant implications for archaeological interpretation. In the light of these results, special attention must be paid to the formation processes of flat Middle Palaeolithic combustion features, as black layers and the material contained in them are not necessarily linked with combustion but with preceding activities or events. In such cases, black layers represent intact remnants of occupation surfaces, concealing significant behavioural and palaeoenvironmental information relevant to the reconstruction of Middle Palaeolithic societies.     

Lithic production,site formation and Middle Palaeolithic palimpsest analysis: in search of human occupation episodes at Abric del Pastor Stratigraphic Unit IV (Alicante,Spain)

We present the results of an exercise in Middle Palaeolithic palimpsest analysis geared toward the identification of human occupation episodes. It is based on a combined reading of the archaeosedimentary deposit and the archaeological record of Stratigraphic Unit IV from Abric del Pastor (Alcoy, Alicante, Spain), chronologically framed within MIS 4–5. A study of site formation processes coupled with archaeostratigraphic analysis of the lithic record incorporating Raw Material Units (RMU) and refits, as well as with combustion features and faunal remains enabled identification a minimum of 4 and a maximum of 6 human occupation episodes within lithostratigraphic units IVa, IVb and IVc. Through our data it reaches a high resolution temporal frame close to the ethnographic time scale, which constitutes a significant contribution for the knowledge of human occupations types and landscape use in the Mediterranean rim of the Iberian Peninsula during Middle Palaeolithic.     

THE TECHNOLOGICAL AND TYPOLOGICAL BEHAVIOUR OF A NEANDERTHAL GROUP FROM EL SIDRÓN CAVE (ASTURIAS,SPAIN)

This paper presents the first detailed analysis of the lithic industry from El Sidrón Cave. Previously we have published other works concerning Anthropology and Palaeogenetics. The lithic assemblage contains 415 artefacts coming from both unofficial and official excavations and is largely flake‐based. The raw material derives from the immediate cave environment, and is mostly chert, with quartzite in a lesser proportion. To date, 67 artefacts have been refitted, including some tools and cores. The spatial distribution of the refitted lithic artefacts confirms, on the one hand, the unity of the assemblage and, on the other, its secondary context.     

Recent Prehistoric Field Research in Central Tunisia: Prehistoric Occupations in the Meknassy Basin

Recent field prospection and test excavations in the Meknassy Basin (Central Tunisia) has revealed many prehistoric sites covering almost all the phases of North African prehistory from the Palaeolithic to the Neolithic. Excavations at the Aïn El-Guettar Mousterian site has yielded a faunal assemblage dominated by bovids and equids. One human tooth was found in situ. The stratigraphic sequence contains charcoal-rich occupation layers with faunal, human and lithic finds. A level with an industry resembling the Aterian was found beneath a Mousterian layer. The excavations at Aïn Oum Henda 2 (Jebel Maloussi) provided many Middle Palaeolithic lithic artefacts, some of which are pedunculates. From the excavations of the Rammadiya El Oghrab (Jebel Bou Hedma) we recovered some bones of antelope, many fragments of ostrich egg shell (among them a worked disc), an enormous quantity of flint (tools and splinters) and of land snails. In spite of the scarcity of land snails and the absence of bone in the rammadiya of Jebel Bou Hedma 1, the site produced a beautiful flint collection including an arrowhead found on the surface, which led us to place the site in the Neolithic.     

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.     

Behavioural and Taphonomic Patterning at Katanda 9: a Middle Stone Age Site, Kivu Province, Zaire

Katanda 9, an open air Middle Stone Age site, contains a dense vertically compressed accumulation of lithic and faunal remains. The physical state of these materials indicates prolonged surface exposure before burial and the site shares essential characteristics therefore with many Lower and Middle Stone Age and Lower and Middle Palaeolithic occurrences in Africa and Eurasia. An important goal of archaeological research is to determine what, if any, anthropogenic signature can be extracted from distributional data and this article utilizes Katanda 9 to suggest an approach to such spatial analysis. It employs a bottom-up, top-down strategy which works in sequential fashion first to determine and control for taphonomic bias and secondly to fit the resultant pattern to models of hominid behaviour. It proposes that questions be posed in nested hierarchical fashion and that probabilities of correctness be assessed. It concludes that the distribution of materials observed at Katanda is most consistent with a nuclear family pattern.     

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.     

Taphonomy at Hermies,France: A Mousterian Knapping Site in a Loessic Context

Abstract

The recent excavation of Hermies, a Mousterian (Middle Palaeolithic) flintknapping site in northern France, sheds light on natural alteration of a lithic assemblage in a loessic sediment. An extensive, well preserved stratigraphic zone grades into a more disturbed area. During excavation we recorded taphonomic indicators such as the dip and strike of in situ pieces, the scattering of artifacts and refitting of broken specimens, and microscopic alteration, principally natural, of flakes. While the composition of the lithic assemblage is less sensitive to erosion than we would expect, the vertical and horizontal dispersion of finds at Hermies is related to natural processes active in the lower and wetter parts of the site. Of particular note is that the dispersion can be associated with polish produced by the natural growth of roots rather than by human use. Some “tools”conventionally identified as denticulaters and notches display no use-wear, and we suggest they were created accidentally by processes such as shock, trampling, and crushing within dense clusters of debitage. This correlation of debitage clusters with increased presence of notches and denticulates is reported from many open-air Mousterian sites; since these two tool forms define the Denticulate Mousterian facies, some reevaluation of those facies is necessary.     

Economic and environmental changes during the 4th and 3rd millennia BC: the 25th Jubilee Symposium of the AEA in Bad Buchau,southern Germany

Abstract

This study represents the first detailed published analysis of a relatively large archaeologically derived faunal assemblage in eastern Beringia for the Late Pleistocene/Early Holocene. The faunal remains, dated to 10,100 cal. BP, are well preserved and have highly resolved spatial association with lithics and hearth features. Factors in the formation of the assemblage are assessed through analyses of weathering, presence/absence of carnivore damage, fragmentation patterns, bone density, and economic utility. Taphonomic analyses indicate that human transport and processing decisions were the major agents responsible for assemblage formation. A spatial model of wapiti and bison carcass processing at this site is proposed detailing faunal trajectories from the kill sites, introduction on site in a central staging area to peripheral marrow extraction areas associated with hearths and lithic items. Data from mortality profiles, spatial analysis, and economic analysis are used to interpret general economy and site function within this period in Interior Alaska. These data and intersite comparisons demonstrate that considerable economic variability existed during the Early Holocene, from broad spectrum foraging to efficient, specialized terrestrial large mammal hunting.     

Thermoluminescence dates for the Middle Palaeolithic site of Chez-Pinaud Jonzac (France)

Thermoluminescence dating of heated flint artefacts from the Middle Palaeolithic sequence of Chez-Pinaud Jonzac (France) places an assemblage of Quina type Mousterian into MIS 4, while the overlying assemblage of Denticulate Mousterian which is followed by two layers with Mousterian of Acheulean Tradition are all assigned to MIS 3. TL dating is used to verify the mixed nature of deposits from which diagnostic Middle as well as Upper Palaeolithic tools were recovered. The TL ages are significantly different for samples from this layer and broadly agree with the archaeological attributions. While the study is generally limited by the low number of heated samples available, a correlation with a generalized chronostratigraphic sequence is possible by including proxy data from the faunal remains associated with the lithic assemblages in question. The Quina Mousterian in southwestern France, therefore, can be placed by chronometric dating methods in MIS 4 to MIS 3.     

AN UPPER PALAEOLITHIC FLINT AND CHERT ASSEMBLAGE FROM HOWBURN FARM,SOUTH LANARKSHIRE,SCOTLAND: FIRST RESULTS

This paper describes the discovery of the first open‐air Upper Palaeolithic site to be found in Scotland, at Howburn, near Biggar in South Lanarkshire. An account is given of the composition and distribution of the lithic assemblage, which is discussed in terms of its British and north‐west European context. Provisional parallels drawn are with the Late Hamburgian (Havelte) sites and assemblages of southern Scandinavia, northern Germany and the Netherlands. There is no absolute dating evidence for the site, but an age in the region of 12,000 ¹⁴C yr BP, towards the end of the earlier (Bølling) Lateglacial Interstadial stage, is proposed on the basis of the lithic artefacts.     

The Upper Palaeolithic Lithic Industry of Nazlet Khater 4 (Egypt): Implications for the Stone Age/Palaeolithic of Northeastern Africa

Between Marine Isotope Stage (MIS) 4 and 2, Northeast Africa witnessed migrations of Homo sapiens into Eurasia. Within the context of the aridification of the Sahara, the Nile Valley probably offered a very attractive corridor into Eurasia. This region and this period are therefore central for the (pre)history of the out-of-Africa peopling of modern humans. However, there are very few sites from the beginning of the Upper Palaeolithic that document these migration events. In Egypt, the site of Nazlet Khater 4 (NK4), which is related to ancient H. sapiens quarrying activities, is one of them. Its lithic assemblage shows an important laminar component, and this, associated with its chronological position (ca. 33 ka), means that the site is the most ancient Upper Palaeolithic sites of this region. The detailed study of the Nazlet Khater 4 lithic material shows that blade production (volumetric reduction) is also associated with flake production (surface reduction). This technological duality addresses the issue of direct attribution of NK4 to the Upper Palaeolithic.     

Assessing the distribution of African Palaeolithic sites: a predictive model of collagen degradation

In order to assess the distribution of African Palaeolithic sites and hominin remains, we need an understanding of the factors that may affect the preservation of archaeological material in the fossil record. One of the main factors that is thought to affect seriously the global distribution of fossil remains is taphonomy, but it would seem that taphonomic processes may themselves be overprinted by collagen degradation.The rate of collagen loss is highly temperature dependent, and it has been shown that bone is more likely to be preserved in areas of lower temperature and so lower collagen loss. Hence, it would be expected that fossil fauna remains would be distributed in areas of low collagen loss, i.e. low temperature. Conversely, lithics will not be subject to a temperature bias in their preservation. We have tested this hypothesis through the use of archaeological material.Our results show that the distributions of both lithic and faunal assemblages are non-random across the African continent, with all archaeological sites being found in areas of relatively low collagen degradation. This implies that bone collagen degradation is not the only factor affecting the distribution of African Palaeolithic sites and hominin remains. We suggest that the site distribution is not a reflection of bias in excavation history, but is a real phenomenon reflecting hominin habitat choice.     

Middle Palaeolithic Refugium,or Archaeological Misconception? A New U-series and Radiocarbon Chronology of Abric Agut (Capellades,Spain)

New U-Series and C14 (AMS) dates are provided for the Abric Agut (Capellades, Barcelona, Spain). This site was previously considered to be of Middle Palaeolithic age according to the characteristics of the lithic assemblage. In addition, human teeth were uncovered and attributed to neandertals. However, radiometric dating clearly indicates a Late Pleistocene-Early Holocene age.     

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 Romanı&#x0301; 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.     

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.     

Trampling vs. Retouch in a Lithic Assemblage: A Case Study from a Middle Stone Age Site,Steenbokfontein 9KR (Limpopo,South Africa)

At the site of Steenbokfontein 9KR, virtually 80% of the lithic blanks presented retouch—an extreme proportion for Middle Stone Age assemblages. The high percentage of putative retouch led us to investigate whether post-depositional processes played a role in the preservation of the lithic assemblage. We designed and performed an experiment that reproduced all the archaeological conditions inferred from the site formation analyses to determine if the archaeological assemblage was trampled or retouched. We defined several qualitative attributes and studied both trampled and retouched experimental samples, and compared them to the archaeological material. We subsequently performed different statistical analyses and a correspondence analysis with all the macro qualitative attributes that we defined. We were then able to discern which attributes were the most eloquent variables and assess the usefulness of a multivariate analysis in discriminating between trampling and retouch.     

The chert abundance ratio (CAR): a new parameter for interpreting Palaeolithic raw material procurement

Raw material provenance and procurement studies are an essential research line to infer landscape exploitation, mobility dynamics and territorial management among prehistoric hunter-gatherer groups. This paper proposes an original and intuitive method, the chert abundance ratio, aimed at quantifying lithic resource occurrence in the landscape while considering the geological natural factors of an area (chert-bearing formation extent, thickness, occurrence index, size and chert content). The resource availability can be statistically compared to any archaeological assemblage distribution to define the procurement strategies, whether generalist or selective, and the mobility patterns. The study area, the north-east of the Iberian Peninsula, focused in the Prades Mountains, represents a regional scenario with high chert disposal shared by several Late Upper Palaeolithic occupations. The discrimination of the procurement areas is used as a parameter for outlining the foraging radius and the territorial range, contributing to an understanding of several aspects of the settlement, such as site functions, occupation length or intensity and group size.
