Neanderthal Shell Tool Production: Evidence from Middle Palaeolithic Italy and Greece

The vast majority of tools recovered from Palaeolithic sites are made of stone varieties. Only rarely do non-lithic implements come to light, let alone tools produced on marine mollusc shell. Interestingly, a good number of shell implements made on Callista chione and Glycymeris sp. valves have been reported from 13 Middle Palaeolithic (Mousterian) sites in southern peninsular Europe. Of these, more than 300 specimens display evidence of deliberate edge retouch. They are all considered products of Neanderthals and date from ~110?ka BP to perhaps ~50?ka BP. In this paper, we review the evidence for Mousterian shell tool production in Italy and Greece??the only two countries in which such tools have been securely identified??and present experimental results obtained in the effort to understand the production process and typo-functional role(s) of the artefacts. We examine the general provisioning pattern of raw materials, as well as the typological, species-related and chronological data pertinent to the production of shell tools by Neanderthals. The data suggest that the Mousterian shell scrapers are a response to poor availability of lithic raw material in the areas of occurrence, and may be best described as an extension of chipped stone technologies to specific types of marine shell, their form defined by an existing mental template. As such, they constitute evidence for refined adaptation strategies and advanced provisioning of resources amongst Neanderthals, and may lend further support to the idea that these hominids displayed a degree of complex behaviour.     

Disappearing from the World: An Archaeological Perspective on Neanderthal Extinction

This paper is concerned with the statistical precision of radiocarbon dating at the earlier range of its efficacy – the period into which falls the extinction of the Neanderthals. The many potential problems affecting accuracy of this technique are discussed as a caveat as to what one might expect of future research and development in this field. The main aim of the paper, however, is to examine exactly what our chronological precision is in the period 30–40 ka BP, i.e. at around five to seven half lives of radiocarbon. If mathematical models of Neanderthal extinction are correct, the whole process could have occurred within the error of one radiocarbon date at two standard deviations, which does not bode well for understanding what must have been a complex set of processes. The assumptions made by palaeoanthropologists working with this problem are discussed, particularly in relation to how dates are actually used, and how sedimentology affects chronology. These problems aside, a coarse and necessarily provisional attempt to interpret the existing archaeological database is made, with the assumption that Late Middle Palaeolithic and 'transitional' industries are proxy indicators of Neanderthal presence in a region. From this, it is suggested that the processes of Neanderthal extinction began by c. 40 ka BP in the Balkans and Central Europe, radiating out from there, leaving Neanderthals on the periphery of their old distribution (southern Iberia, southern Italy, Crimea, Siberia, and one might predict the United Kingdom) as late as c. 29 ka BP. The processes differ in signature (and therefore by extension nature and quite possibly cause) region to region, and because of this, the role of anatomically modern humans in the extinction of Neanderthals is questioned.     

Circum-mortem damage to some ancient African hominid crania: a taphonomic and evolutionary essay

Close examination of three early hominid crania from Africa yields taphonomic information long after they were excavated, and can contribute information relevant to their dating and taxonomic status. The condition of the bone and breaks and markings are reviewed in the Florisbad, Saldanha and Broken Hill (Kabwe) crania, indicating animal biting while the bone was still fresh in the first and last of these specimens. However, the damage to the base of the Kabwe cranium indicates that there may also have been breakage by hominids, including scorings near the margin of the squamous suture. No tooth marks are observed on the Saldanha cranium, but a depressed fracture and other lesions indicate hominid damage to fresh bone. Postmortem weathering indicates cranial thickness even greater than the original measurements, which implies a more primitive evolutionary status for Saldanha than for Kabwe. This view is supported by other morphological evidence, and suggests a considerably earlier date for Saldanha and a classification asHomo erectus.

Résumé L'examen à fond de trois crânes d'hominidés anciens de l'Afrique fournit des données taphonomiques longtemps après la fouille, et peut livrer informations quant à leur date et à leur statut taxonomique. L'état de l'os et les cassures et d'autres traces sont étudiés dans les crânes de Florisbad, Saldanha et Broken Hill (Kabwe); dans ceux de Florisbad et de Broken Hill on constate que l'os a été mordu par des animaux lorsqu'il était encore frais. Cependant les dégâts à la base du crâne de Kabwe—y compris des stries près du bord de la suture squameuse—indiquent qu'il peut aussi avoir été cassé par des hominidés.Il n'y a pas de traces de morsures sur le crâne de Saldanha, mais on y observe une fracture aplatie et d'autres lésions qui indiquent que l'os frais a été endommagé par des hominidés. A cause des altérations survenues après la mort, on constate que le crâne original était même plus épais que les premières mésures l'indiquaient, ce qui implique un statut évolutionnaire plus primitif pour Saldanha que pour Kabwe. Cette idée, renforcée par d'autres indices morphologiques, suggère que Saldanha est beaucoup plus ancien que l'on ne croyait, et doit être classifié commeHomo erectus.

     

Bone diagenesis in the European Holocene II: taphonomic and environmental considerations

We have applied cluster analysis to mercury intrusion porosimetry data from 219 archaeological bones (121 human and 98 animal) and soil chemistry data from 219 accompanying soil samples (1 per bone sample), to investigate the influence of soil chemistry on bone preservation. The samples chosen for the study were obtained from sites ranging in time from the pre-modern to the Mesolithic and were representative of burial environments across Europe (from the Baltic to the Mediterranean). These results represent the single largest database for archaeological bone preservation in the European Holocene to date and demonstrate the potential for large-scale diagenetic studies to help develop long term preservation strategies for our European heritage. Despite the variety of sites and environments, bones could be categorised into only four main diagenetic types. Furthermore, soil chemistry appears to significantly affect only one type of preservation, the pathway characterised by loss of mineral. In neutral to basic soils, taphonomy and in particular the differences between the treatment of human and animal remains, becomes the dominating factor in determining preservation. Using these results, strategies for heritage management of archaeological sites can be suggested; grouping sites into those requiring immediate excavation and those where in situ preservation is viable.

Modern human,early modern human and Neanderthal limb proportions

The limb proportions of 686 subjects (461 men and 225 women) from five ethnic groups (White, Inuit, Gurkha, Bantu, San) have been compared. Stature, limb and skeletal measurements were taken directly from the subjects by one observer. The brachial and crural indices of the Whites were markedly smaller (lower) than those of the other populations. The crural indices of the Inuit were similar to those of the two African populations, but this may be an artefact from relatively small numbers for the Inuit population. There is no sexual dimorphism for the brachial index, but men have larger (higher) crural indices than women, a finding which probably relates to the relatively broad pelvises and consequently long femurs of women. The two African populations have long limb lengths standardized for height compared to the Gurkha and Inuit populations, with the Whites intermediate. This finding is consistent with Bergmann's thermoregulatory rule. The correlations between distal abbreviation and limb abbreviation for both the upper and lower limbs are poor and negative. Relatively long limbs tend to have smaller distal segments than relatively short limbs and for the legs this may constitute a safeguard for the integrity of the medial and cruciate ligaments of the knee. For these five modern populations distal abbreviation cannot be used as a proxy for limb abbreviation and there is no justification for linking distal abbreviation with climatic selection. Skeletal data relating to nine Neanderthal and 25 early modern humans have also been analysed. The analysis confirms marked limb and distal abbreviation for the Neanderthals compared to early and contemporary modern humans, but this conclusion presupposes that the taxonomic classes are correct and that limb proportions were not used originally as a class discriminant. For these archaic populations there is a moderate positive correlation between lower limb abbreviation and distal abbreviation, but the numbers are small and the confidence intervals very wide. In view of the findings for modern populations, and until more relevant fossils are available, it is probably unwise to use the crural index as a proxy for limb abbreviation in archaic populations.

Large carnivore attacks on hominins during the Pleistocene: a forensic approach with a Neanderthal example

Interaction between hominins and carnivores has been common and constant through human evolution and generated mutual pressures similar to those present in worldwide modern human-carnivore conflicts. This current interaction is sometimes violent and can be reflected in permanent skeletal pathologies and other bone modifications. In the present paper, we carry out a survey of 124 forensic cases of dangerous human-carnivore encounters. The objective is to infer direct hominin-carnivore confrontation during the Pleistocene, which is important to understand behavioral changes during human evolution. In addition, the case of Neanderthals is analyzed in order to find evidence of past attacks using forensic observations. The results obtained pose that Neanderthals could potentially have been involved in dangerous encounters during the Pleistocene, validating our methodology to approach past attacks from a forensic perspective.     

Characterization of a current coprogenic sample originated by Canis lupus as a tool for identifying a taphonomic agent

We study a skeletal sample digested by Iberian wolf (Canis lupus signatus) in order to finding diagnostic features of digestion caused by this agent. The remains were taken from scats collected in different natural areas in the northwestern Iberian Peninsula. We tested different methods to recover the remains with the goal of not produce biases, and we evaluated the most appropriate methods. The results were compared with those reported by other authors who have also worked with samples digested by wolves. Bias during the procurement of the skeletal assemblages seems to be a significant cause of the differences observed between the samples. We found that it was necessary to fully recover all remains and individually analyze all modifications, even in small-sized remains. Taphonomic characterization was performed by analyzing physical and biochemical modifications. We believe that these results may be useful in the study of archaeological and paleontological assemblages.     

Charcoal scarcity in Epigravettian settlements with mammoth bone dwellings: the taphonomic evidence from Mezhyrich (Ukraine)

Fuel management during the Paleolithic periods is an important issue to understand past human subsistence. Numerous Palaeolithic sites relate an abundance of burnt bones in hearths and an absence or scarcity of wood charcoals, which leads studies to focus on burnt bone remains and the use of bones in hearths. Few works take into account the micro-residues of wood charcoals which can still be present in hearth areas and excavated sediments. We studied the Epigravettian site with mammoth bone dwellings of Mezhyrich (Ukraine) previously characterized by its high content of burnt bones and an “absence” of wood charcoal during the so-called mammoth steppe. The presence or absence and proportions of both wood charcoals and burnt bones were quantified in macro-, meso- and microscale sediment size fractions by an image analysis method. Our results show that excavations during field-works at Mezhyrich give only a partial image of the original anthracological record and that most charcoal materials are lost with standard archaeological and anthracological approaches. The scarcity of charcoals in this site was possibly due to an important mass reduction accentuated by the addition of bones in hearths. By applying our protocol we recovered a significant amount of wood charcoals which provides the first ¹⁴C dates from charcoals at Mezhyrich. Numerous charcoals are identified contributing subsequent information about vegetation, environment and burning practices. They indicate, by comparison with pollen data already collected, the presence of forest patches in a mammoth steppe landscape, which might have influenced the collecting behavior of Epigravettian populations.     

Scarcity and prosperity in postwar childbearing: explorations from a life course perspective

An investigation of the role of Depression scarcity and subsequent prosperity on the postwar baby boom using two longitudinal cohorts from the 1920s defined by birth. The study into account variability in Depression experiences and alternative life pathways (ascent, decline and stability across generations) in attempting to explain linkages between the Depression and postwar fertility. Easterlin's relative income theory is explored and found to be an insufficient model for explaining the observed demographic behavior. It fails to take variability in Depression experience and life pathways into account, whereas fertility records of cohort members showed striking differences according to those variables. By relating 2 sets of variations, 1) Depression experience, and 2) subsequent adult status and accomplishments during a period of affluence and economic growth, circumstances were identified that enhanced different imprints of a Depression childhood, the bearing of more children, and fertility constraint. The interdependence of social change and life course is underscored by this study.     

Coastal villas, maritime villas; a perspective from Southern Britain

The coastal siting of Romano-British villas is generally discussed and attention is particularly focused on the Channel seaboard of Britain. Here, comparison is made with the distribution of those natural harbours and offshore anchorages that have been traditionally favoured by sailing craft. These are clearly described in the first edition of Hobb’s British Channel Pilot of 1859. A relationship is proposed between the rare incidence of leeward anchorages and the siting of villas at Folkestone, Eastbourne, Sidlesham, Weymouth and Honeyditches. Other villas with significant maritime settings are identified at Southwick, Fishbourne, Emsworth, and Brading all of which adjoin harbours or ‘roads’ identified by Hobbs. In the Eastern Solent, anchorages at Spithead, Mother Bank and Cowes Roads are equated with the Magnus Portus described by Ptolemy. At this location some supportive evidence is offered by Roman ceramics recently recovered from the seabed. Attention is also drawn to maritime themes in the mosaics at Fishbourne, Brading and Low Ham where the chosen mythological scenes appear to be an overt expression of contemporary nautical preoccupations.     

Morphological taphonomic transformations of fossil bones in continental environments,and repercussions on their chemical composition

The aim of this paper is to provide a summary of structural or surface modifications of vertebrate bone remains in continental palaeoenvironments that may have repercussions on their chemical composition. Both before and after burial, a different set of physical, chemical and biological agencies may produce modifications of the bone morphological structure and/or bone chemical composition. Several of these morphological modifications are diagnostic of particular agents, which otherwise may not be noticed or identified in a fossil association. In order to understand diagenesis, those events that occurred before final burial have to be considered, as they may strongly modify the bone morphological structure and influence post–burial changes.     

Studying Pleistocene Neanderthal and cave hyena Dietary Habits: Combining Isotopic and Archaeozoological Analyses

Stable isotope analysis is increasingly used to gain insight in the configuration of Pleistocene ecosystems. The application of isotope analysis to Neanderthal and cave hyena bone assemblages has led to hypotheses about the niche differentiation between these species. Comparing isotopic data with archaeozoology analyses shows discrepancies between the results of both analytical methods. Here, the results of all northwest European stable isotope studies on Neanderthals are reviewed. The emphasis of the analysis is on a sample of sites from MIS 4-3 in southwest France. Causes of the discrepancy between archaeozoological and stable isotope results are discussed and hypotheses reconciling the data are proposed. Recommendations for further research will allow testing of the hypotheses and increase our understanding of the functioning of Pleistocene ecosystems.     

Temporal frequency distributions of alluvium in the American Southwest: taphonomic,paleohydraulic, and demographic implications

The use of radiocarbon frequency distributions to reconstruct prehistoric human and animal populations must account for taphonomic loss and other factors that affect the archaeological and paleontological records. Surovell et al. (JAS, 36, 1715–1724) have recently proposed a correction for “taphonomic bias” that is based on the radiocarbon frequency of a global sample of volcanic deposits. Analysis of 717 radiocarbon dates sampled from the alluvium of the San Pedro and Santa Cruz rivers and their tributaries in southeastern Arizona shows that discovery and scientific biases also play an important role in the creation of radiocarbon frequency distributions, and that the rate of “taphonomic bias” in prehistory is not predicted by the radiocarbon frequency of volcanic deposits. The latter principle is further argued using a sample of 123 Pliocene to Clovis-age proboscideans from the San Pedro Valley. We propose an alternative model that is based on the nature of the stratigraphic record, with discovery bias, scientific bias, taphonomic loss, and the shape of the calibration curve all operating to influence the temporal frequency distribution of radiocarbon-dated prehistoric phenomena.     

Inter-firm knowledge creation: A re-appreciation of embeddedness from a relational perspective

Embeddedness studies often follow a structural approach, arguing, for example, that long-term relations are necessary for trust to develop. A case study of the Dutch company Océ shows that such need not be the case. Taking the process of knowledge creation as the starting-point of analysis, this can be explained. However, it is the content of network relations, what is going on inside them, that needs to be examined rather than their structure. This approach is more in line with Granovetter's original embeddedness argument. After all, it is not the fact that actors are embedded that matters, but how this affects their actions.     

Extraction and sequencing of human and Neanderthal mature enamel proteins using MALDI-TOF/TOF MS

We report here the first results of a method to extract and sequence mature enamel proteins from modern human and Neanderthal tooth enamel. Using MALDI-TOF/TOF mass spectrometry and a combination of direct sequencing and peptide mass mapping we have sequenced a peptide from the tyrosine-rich amelogenin peptide (TRAP) of the X isoform of the amelogenin protein for modern and recent human samples. We also report our results from two Neanderthal enamel samples where we were also able to recover fragments of the TRAP protein, which had a similar sequence to the modern human samples.     

Hunting behavior and Neanderthal adaptability in the Late Pleistocene site of Pech-de-l'Azé I

The late Mousterian of Acheulian tradition (MTA) site of Pech-de-l'Azé 1 shows a very particular stratigraphic sequence characterized by numerous elements not usually found in Mousterian contexts such as avifauna exploitation and the use of hundreds of mineral pigments. Recent zooarchaeological and skeletochronological analyses provide new insights into the evolution of subsistence behaviors and settlement patterns of the Neanderthals that inhabited the shelter. Due to changes in hunting season, Neanderthals adapted their hunting strategies, exploiting various red deer populations which presented very different behavior. The evolution in the seasonal occupation of the shelter may have been the results of major modifications of its (series of roof collapsed) which induced a shrank in inhabitable space., which forced the Mousterians to adjust the way they used the cavity to its characteristics in order to optimize its exploitation. The conclusions underline the excellent adaptability of the Neanderthals to their physical environment.
