The Palaeolithic of the Middle Son valley, north-central India: Changes in hominin lithic technology and behaviour during the Upper Pleistocene

The Middle Son valley in north-central India preserves extensive Quaternary alluvial deposits. A long history of archaeological and geological research in the valley has resulted in the discovery of lithic assemblages ranging from Lower Palaeolithic to microlithic, a rich corpus of fossilised faunal remains, and ash deposits from the 74,000 year-old Toba supereruption. This paper reviews the chronology and stratigraphy of the valley’s Quaternary sediments, and presents a model that hypothesizes the temporal sequence of important lithic assemblages from excavated and surface contexts. Artefacts in these assemblages are analysed and changes in lithic technology through time are described; this evidence is used to propose shifts in hominin behaviour and demographic structure in this region during the Upper Pleistocene. Recognising gaps in our understanding of the Middle Son record, future avenues of research are recommended that will build upon previous research and address questions of palaeoanthropological significance. The Middle Son valley preserves a long and rich record of hominin occupation from all periods of the Palaeolithic that is rarely paralleled by other sites in India.     

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.     

Quantitative micromorphological analyses of cut marks produced by ancient and modern handaxes

In this study, we analyse the three-dimensional micromorphology of cut marks on fossil mammal remains from a ∼0.5 million year old Acheulean butchery site at Boxgrove (West Sussex, southern England), and make comparisons with cut marks inflicted during the experimental butchery of a roe deer (Capreolus caproelus) using a replica handaxe. Morphological attributes of the cut marks were measured using an Alicona imaging microscope, a novel optical technique that generates three-dimensional virtual reconstructions of surface features. The study shows that high-resolution measurements of cut marks can shed light on aspects of butchery techniques, tool use and the behavioural repertoire of Lower Palaeolithic hominins. Differences between the experimental cut marks and those on the Boxgrove large mammal bones suggest variation in the angle of the cuts and greater forces used in the butchery of the larger (rhinoceros-sized) carcasses at Boxgrove. Tool-edge characteristics may account for some of these differences, but the greater robusticity of the Boxgrove hominins (attributed to Homo heidelbergensis) may be a factor in the greater forces indicated by some of the cut marks on the Boxgrove specimens.     

Taphonomy and zooarchaeology of the Upper Palaeolithic cave of Dzudzuana,Republic of Georgia

We present the results of a detailed taphonomic and zooarchaeological study of the faunal remains from the Upper Palaeolithic layers of Dzudzuana Cave, Republic of Georgia. This study presents the first carefully analysed Upper Palaeolithic faunal assemblage from the southern Caucasus and thus serves as a significant point of reference for inter‐regional studies of Upper Palaeolithic subsistence in Eurasia. A series of intra‐site taphonomic comparisons are employed to reconstruct the depositional history of the bone assemblages within the different occupational phases at the site and to investigate subsistence, meat procurement and bone‐processing strategies. Caucasian tur (Capra caucasica), aurochs (Bos primigenius) and steppe bison (Bison priscus) were the major prey species throughout the Upper Palaeolithic. Their frequencies do not change significantly over time, and nor does bone preservation vary by layer. The assemblage is characterised by significant density‐mediated biases, caused by both human bone‐processing behaviours and in situ post‐burial bone attrition. Bone marrow extraction produced large numbers of unidentified bone fragments, many exhibiting green bone fractures. The density and size of bone assemblages and the extent of fragmentation indicate that Dzudzuana Cave was repeatedly occupied by Upper Palaeolithic foragers over many years. Skeletal part representation and butchery marks from all stages of carcass processing suggest that prey occasionally underwent field butchery. Intra‐site taphonomic comparisons highlight uniform patterns of cultural and economic behaviours related to food procurement and processing strategies. Copyright © 2007 John Wiley & Sons, Ltd.     

Investigating interrelationships between Lower Palaeolithic stone tool effectiveness and tool user biometric variation: implications for technological and evolutionary changes

Lower Palaeolithic hominins are thought to have been dependent upon stone tools during the acquisition and processing of food resources. Hence, it is hypothesized that the evolutionary advantages provided by efficient stone tool use may have selected for anatomical changes observed in the hand during this period. Similarly, hominin manipulative capabilities are suggested to have been of consequence to Lower Palaeolithic technological choices and tool use capabilities. The extent and character of these relationships are not, however, fully understood and it is not known whether these hypothesized co-evolutionary and co-dependent relationships are consistent across varying technological and task-type conditions. Here, six key biometric parameters of the hand are investigated in terms of their statistical relationship with cutting efficiency using both flakes and handaxes over extended periods of use and in multiple types of cutting task. Results indicate that (1) both handaxe and flake cutting efficiencies are significantly related with biometric variation of individual tool users, (2) relationships between biometric parameters and efficiency are consistent across extended durations but vary dependent upon task-type conditions, (3) manipulative strength is the most significant biometric trait in terms of predicting flake efficiency, while (4) hand size is the strongest predictor of handaxe cutting efficiency. These results demonstrate the long-term impact that stone tool use likely had on the evolution of hominin biometric variation during the Lower Palaeolithic, while also highlighting the variable influence of different tool use contexts. Most notably, results indicate that the onset of the Acheulean may have been dependent, a priori, upon hand dimensions that are close to the modern human range, and that prior to the appearance of this anatomy, handaxe use would have been an impractical (i.e. inefficient) tool use behaviour compared to the use of flakes.     

Experimental study of cut marks made with rocks unmodified by human flaking and its bearing on claims of ∼3.4-million-year-old butchery evidence from Dikika, Ethiopia

In order to assess further the recent claims of ∼3.4 Ma butchery marks on two fossil bones from the site of Dikika (Ethiopia), we broadened the actualistic-interpretive zooarchaeological framework by conducting butchery experiments that utilized naïve butchers and rocks unmodified by human flaking to deflesh chicken and sheep long limb bones. It is claimed that the purported Dikika cut marks present their unexpectedly atypical morphologies because they were produced by early hominins utilizing just such rocks. The composition of the cut mark sample produced in our experiments is quite dissimilar to the sample of linear bone surface modifications preserved on the Dikika fossils. This finding substantiates and expands our earlier conclusion that—considering the morphologies and patterns of the Dikika bone surface modifications and the inferred coarse-grained depositional context of the fossils on which they occur—the Dikika bone damage was caused incidentally by the movement of the fossils on and/or within their depositional substrate(s), and not by early hominin butchery. Thus, contrary to initial claims, the Dikika evidence does not warrant a major shift in our understanding of early hominin behavioral evolution with regard to carcass foraging and meat-eating.     

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.     

Stable isotope analysis of prehistoric populations from the cemeteries of the Middle and Lower Dnieper Basin,Ukraine

This paper presents the results of new stable isotopes (carbon and nitrogen) analysis of human, faunal and fish remains from thirteen cemeteries from the Middle and Lower Dnieper Basin, Ukraine. The results are integrated with earlier analyses, undertaken solely on human samples, in order to provide a comprehensive overview of subsistence across the Upper Palaeolithic through to Eneolithic periods in this region. This is the first time that a combined sample of human, faunal and fish remains has been studied in order to interpret subsistence strategies across these periods in Ukraine. The total dataset comprises 113 samples of human, faunal and fish remains, 59 of which include new analyses of faunal and fish remains that have not previously been made available for study (Table 1). The analysis of the faunal and fish remains allows for a consideration of trophic levels which indicates that the consumption of freshwater fish occurs from the Epipalaeolithic period onwards. Whilst the majority of the cemeteries and the individuals therein cluster in relatively tight groups, there is a significant offset between the human and faunal samples due to the consumption of freshwater resources. The fish samples analysed in the study appear to exhibit a relatively random distribution when compared to the other samples analysed. In general, freshwater resources remain significant through until the end of the Neolithic period and into the Eneolithic period at the sites investigated.     

A spotted hyaena den in the Middle Palaeolithic of Grotta Paglicci (Gargano promontory,Apulia, Southern Italy)

The Palaeolithic sequence of Grotta Paglicci (Gargano promontory, Apulia, Southern Italy) is one of the most important in the Mediterranean area: It comprises the whole Upper Palaeolithic cultural sequence known for the region, as well as Early Middle Palaeolithic and Lower Palaeolithic levels. These earlier phases are best represented in a collapsed room located outside the present-day cave (the so called “external rock shelter”). In this area, a new excavation, started in 2004, brought to light Middle Palaeolithic animal remains associated with evidence of spotted hyaena (SU 64 and 53). The spatial distribution analysis of remains from SU 53 revealed the presence of a bone accumulation area and a wider dispersal of hyaena coprolites. Three main ungulate species (aurochs, fallow deer and red deer) as well as carnivores (spotted hyaena, wolf, fox, wild cat and lynx) and lagomorphs have been identified. The majority of aurochs remains are located in the main accumulation; among these specimens, a complete metatarsal connected with three tarsal bones has been found; a talus and a complete tibia, probably belonging to the same limb, have also been identified. The multidisciplinary study carried out in this paper highlights a specific bone accumulation and scattering pattern in a spotted hyaena (Crocuta crocuta) den. In addition, taphonomy of lagomorph remains indicates the presence of other depositional agents.     

Preliminary U-series and Thermoluminescence dating of excavated deposits in Liang Bua sub-chamber,Flores, Indonesia

We report the results of a test excavation of deposits in a limestone cave sub-chamber located beneath the main chamber of Liang Bua, Flores, Indonesia; the discovery site of the small hominin species, Homo floresiensis. Well-preserved remains of extinct Pleistocene fauna and stone artefacts have previously been identified on the surface of a sediment cone within the sub-chamber. Our excavation of the deposits, at the base of the sediment cone in the sub-chamber (to 130 cm depth) yielded only a few fragmentary bones of extant fauna. Uranium/Thorium (U-series or U/Th) dating of soda straw stalactites excavated from 20 to 130 cm in depth demonstrates that the excavated sediments were deposited during the Holocene. Red Thermoluminescence (TL) dating of the sediments at the base of the excavation (130 cm depth) indicates these sediments were last exposed to sunlight at 84 ± 15 ka (thousand years), similar to red TL ages of cave sediments from the main chamber. Together, these results indicate that the surface faunal remains, which are morphologically analogous to Pleistocene finds from the main chamber excavations, were transported to the sub-chamber relatively recently from the main chamber of Liang Bua and probably originated from conglomerate deposits at the rear of the cave and from deposits around the front entrance. There is no evidence for hominin occupation of the sub-chamber, instead it seems to have acted as a sink for cultural materials and fossil remains transported from the surface via sinkholes. Despite the small number of finds from the test excavation, it is possible that more extensive excavations may yield additional transported cultural and faunal evidence at greater depths.     

Hunted or Scavenged Neanderthals? Taphonomic Approach to Hominin Fossils with Carnivore Damage

Carnivore damage on Neanderthal fossils is a much more common taphonomic modification than previously thought. Its presence could have different explanations, including predatory attacks or scavenging scenarios, which are both situations with important implications concerning Neanderthal behaviour. In the present paper, we analyse several Neanderthal hominin fossils from a taphonomic and forensic perspective in order to infer the nature of the modifications observed on the bone surfaces. Fossils displaying carnivore modifications from Spain, Germany, Belgium and Greece are evaluated from a taphonomic perspective for the first time in a significant sample of hominin specimens. Our results show that the materials analysed have been modified by small to large carnivores and that both attacks and strictly carnivore scavenging events can be inferred. This study also points out the importance of developing taphonomic approaches to the analysis of hominin bone surfaces, which can contribute significantly to knowledge of several aspects of Neanderthal behaviour.

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.     

Demography and the Palaeolithic Archaeological Record

Demographic change has recently re-emerged as a key explanation for socio-cultural changes documented in the prehistoric archaeological record. While the majority of studies of Pleistocene demography have been conducted by geneticists, the archaeological records of the Palaeolithic should not be ignored as a source of data on past population trends. This paper forms both a comprehensive synthesis and the first critical review of current archaeological research into Palaeolithic demography. Within prevailing archaeological frameworks of dual inheritance theory and human behavioural ecology, I review the ways in which demographic change has been used as an explanatory concept within Palaeolithic archaeology. I identify and discuss three main research areas which have benefitted from a demographic approach to socio-cultural change: (1) technological stasis in the Lower Palaeolithic, (2) the Neanderthal-Homo sapiens transition in Europe and (3) the emergence of behavioural modernity. I then address the ways in which palaeodemographic methods have been applied to Palaeolithic datasets, considering both general methodological concerns and the challenges specific to this time period. Finally, I discuss the ability of ethnographic analogy to aid research into Palaeolithic demography.     

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.     

Reconnaissance survey for Palaeolithic sites in the Debed River Valley,northern Armenia

Abstract

The southern Caucasus is a critical region for those interested in Palaeolithic research because of its varied topography and location at the crossroads of Europe, Africa, and Asia. Modern Armenia sits at the heart of this area, but has until now played a small role in broader debates, largely because of its paucity of well-excavated and well-dated sites. To improve this situation, a survey was conducted for Palaeolithic sites along the valley of the Debed River (Lori Depression, northeastern Armenia). Twenty-three open-air sites, spanning the Lower through the Upper Palaeolithic periods, were identified. Most of the lithic material is of Middle Palaeolithic manufacture. Upper Palaeolithic material is also well represented, but only a handful of Lower Palaeolithic artifacts have been identified. Test excavations at several sites suggest that they preserve in situ deposits that may help us to understand the role of the southern Caucasus in the Palaeolithic occupation of Eurasia.     

DID NEANDERTHALS PLAY MUSIC? X‐RAY COMPUTED MICRO‐TOMOGRAPHY OF THE DIVJE BABE ‘FLUTE’*

Archaeological evidence for wind musical instruments made by modern humans has been well established from the Upper Palaeolithic in Europe. Musical instruments evidently made by Neanderthals have not been found so far. The most controversial object is a juvenile cave bear femur with two complete holes, found in 1995 in the Middle Palaeolithic layers of the Cave Divje babe I, Slovenia. The bone was interpreted as a possible Neanderthal ‘flute’, but some scholars have firmly rejected this hypothesis on the basis of taphonomic observations, suggesting a carnivore origin for the holes. Here, we show the results of X‐ray computed micro‐tomography (mCT) performed on the Divje babe I ‘flute’. Our analyses demonstrate that there were originally four holes, possibly made with pointed stones and bone tools. Most surface modifications near the holes, previously interpreted as effects of carnivore gnawing, are post‐depositional marks. Furthermore, a thin layer has been removed around one of the complete holes, producing a flat surface, possibly to facilitate perforation. The new data show that a Neanderthal manufacture of the object cannot be ruled out.     

The Exploitation of Plant Resources by Neanderthals in Amud Cave (Israel): The Evidence from Phytolith Studies

The depositional environments of Amud Cave indicate that phytolith assemblages retrieved from the cave's sediments are an integral part of the Middle Palaeolithic sequence. As such, they provide direct evidence for plant use. The Amud Neanderthals emphasized both wood and grass exploitation. Ligneous parts of trees and shrubs were used mainly for fuel. Herbaceous plants were used for bedding, possibly fuel, and for food. There is clear and repetitive evidence for the exploitation of mature grass panicles, inferred to have been collected for their seeds. These findings suggest that, as with the pattern recently discerned for faunal resources, a broad spectrum of plants has been exploited from at least the end of the Middle Palaeolithic. Phytolith analysis now provides a tool for testing models explaining subsistence and mobility patterns during the Levantine Middle Palaeolithic and for better understanding the role of vegetal resources in shaping these patterns.     

Rabbits as Food at the end of the Upper Palaeolithic at Molí del Salt (Catalonia,Spain)

Many factors have been causally linked to the diversification of hunting during the European Palaeolithic: declining supplies of high‐ranked prey, considerable human demographic growth, reduced residential mobility, larger populations of ubiquitous small mammals and significant technological developments. However, small prey exploitation was not uniform: the European rabbit (Oryctolagus cuniculus ) is the most frequent species in the Upper Palaeolithic archaeological record of the Iberian Peninsula – south and Mediterranean area – and Southern France. This is demonstrated at Molí del Salt, an Upper Palaeolithic site located at Vimbodí (Catalonia, Spain), whose mammal fauna stands out for the predominance of rabbits [91% of minimum number of individuals (n = 136)]. We analysed the faunal remains from one level [A^sup (c. 12 700–13 000 cal BP)] in order to identify the agent responsible for the faunal accumulation, and to reconstruct aspects of procurement and consumption that shed light on Palaeolithic subsistence strategies in the Northeast Iberian Peninsula. Our results indicate that human agency rather than carnivore activity was responsible for the bone accumulation at Molí del Salt. We identified all the stages in the consumption sequence from skinning to ingestion. We argue that the rabbits were mostly harvested during summer or winter or both seasons. Clearly, the European rabbit was a target species for the human groups which lived at Molí del Salt providing meat, and skin. Copyright © 2016 John Wiley & Sons, Ltd.     

Detecting Palaeolithic Activity Areas Through Electrical Resistivity Survey: An Assessment from Vale de Óbidos,Portugal

The open air Late Pleistocene campsite of Vale de Óbidos provided an opportunity to systematically assess the utility of electrical resistivity surveying for activity area detection at Palaeolithic sites. Detailed surface mapping facilitated the exploration of electrical resistivity effects caused by recent land use activities and post depositional processes. At Vale de Óbidos, tree throw events, ploughing, and earth moving have a more significant impact on soil resistivity than increases in soil moisture associated with pine tree stumps and roots. Resistivity results successfully discriminate activity areas containing hearth features and high densities of fire cracked rocks and artifacts. As an aid for understanding post-depositional processes at archaeological sites and to design excavation and recovery efforts, the technique has great potential for Palaeolithic archaeology and in other prehistoric contexts that lack major architectural remains.     

Taphonomic modifications produced by modern brown bears (Ursus arctos)

Actualism has been a fundamental tool in taphonomy. The knowledge of accumulation patterning of modern faunal allows us to interpret the activity of different actors in the archaeological record and to reconstruct the behaviour of preterit animals and humans in which we are interested. However, until now, there are few works that include bone modifications made by bears amongst those made by carnivores. Most data about bone modifications made by bears have been obtained from the archaeo‐palaeontological record. In most of these assemblages, the presence of bears is related to their period of hibernation. Therefore, in these contexts, the changes documented on recovered bear bones are associated only with cannibalism. In this paper, we present an actualistic study about modifications on bones made by modern brown bears. These animals can cause damage similar to those produced by other large carnivores. Generally, bear activity leaves slight damage, mainly on large‐sized animal bones. However, on bones of small‐sized animals and those of greater fragility, the bears can produce abundant damage. Though not usual, bears can break long bones and consume the complete epiphysis. This study suggests that bears have the potential to be agents of bone modification in fossil assemblages. Consequently, they should be considered as a possible agent of modification of faunal remains in the fossil record. Copyright © 2011 John Wiley & Sons, Ltd.
