A new protocol to differentiate trampling marks from butchery cut marks

Microscopic signatures have previously been used to emphasize the similarities of butchery and trampling marks. The experimental background applied to differentiate both types of marks has been rather limited and authors have sometimes reached conflicting conclusions. This is partly due to methodological reasons: some authors have used very high magnification to examine microscopic features, whereas others have relied on more reduced magnification. Likewise, some experiments have exposed bones to trampling for reduced periods (minutes) whereas others have used longer time periods (hours). The present study stresses that the use of a scanning electronic microscope is not practical for identifying the impact of butchery and trampling marks in complete bone assemblages. It also emphasizes that previous studies have not addressed all the possible variables that could potentially be used to discriminate these marks, nor have they quantified the morphological patterns of each type of mark. Here we present a multivariate analysis of more than a dozen variables and show that butchery and trampling marks have very distinctive microscopic morphology. We advocate the use of a low magnification approach (≤40×), which can enable the analysis of complete assemblages using either hand lenses or binocular lenses. We also show the morphological criteria that differentiate butchery cut marks made with simple and retouched tools. We show that whereas complete discrimination of marks is impossible due to some degree of overlap, the list of criteria derived through multivariate analyses can be confidently used to correctly differentiate butchery and trampling marks in more than 90% of cases.     

Diagnostic criteria for identification of seashell as a trephination implement

Scanning electron microscopy has been applied to experimentally cut bone samples and an ethnographical example of trephination on a human skull in order to produce diagnostic criteria for the identification of mollusc shells as cutting implements used in trephination. Shell scrapes are identifiable by parallel striations in the direction of cut, crossed at 90° by chatter marks caused by uneven movement of the fragile shell-edge across the bone surface.     

Reconstructing the massacre at Fort William Henry,New York

Fort William Henry, in upstate New York, was the site of a legendary siege and massacre in 1757 during the French and Indian War. As part of the terms of surrender, the British garrison was to retreat with all their arms and possessions, thus denying the Indian allies of the French their spoils of war. Contemporaneous and fictionalized accounts of the resulting massacre have often been regarded as exaggerations of actual events. Five men buried in a mass grave within the fort, known as the crypt, however, were clearly victims of the massacre. These men were among the sick and wounded who were unable to make the 15 mile (24 km) journey to Fort Edward and were left in the care of the French. Four of the five men sustained pre-mortem leg trauma that would have resulted in their hospitalization and prevented them from walking. The other massive perimortem trauma on these remains vividly depicts the results of the massacre. Three of the five men were shot in the knee; two of these three were shot elsewhere as well. One man was decapitated. Both the front and back of all the bodies bear cut marks, probably from the use of both axes and long-bladed knives as weapons. The numerous gashes in the thoracic and pelvic regions indicate the men were mutilated. Our analysis of the remains from this mass grave confirms and enhances the historical accounts of the massacre at Fort William Henry. The skeletons of these five men provide gruesome testimony of the assault to which they were subjected.     

A new experimental study on percussion marks and notches and their bearing on the interpretation of hammerstone-broken faunal assemblages

Preliminary experiments on bone breakage have shown the potential utility of quantifying some of its diagnostic features (percussion marks, percussion notches) for taphonomic inferences about human and carnivore involvement in bone breakage in faunal assemblages. The present study increases the range of experiments undertaken to understand the identification of hammerstone percussion (dynamic loading) and its differences from carnivore bone breakage through tooth pressure (static loading). This study contributes to a better understanding of frequencies of percussion marks, uncovers and quantifies those percussion marks that lack key diagnostic features to be identifiable and that could be mistaken with carnivore tooth marks, quantifies notch types, shows different size ranges for notches on bones from small and large fauna than previously reported, quantifies the proportion of notches bearing percussion marks, and introduces new size data for percussion (impact) flakes and percussion marks. Furthermore, all these variables have been applied to a dual experimental set: one experiment using non-modified hammerstones and another based on the use of modified hammerstones. Results vary considerably according to hammerstone type. Some of these taphonomic variables increase the range of equifinality when identifying marks and notches created by different human and non-human agents. This calls for further caution when using isolated variables and features rather than a holistic approach to make taphonomic inferences.     

Unusual burial from an early Neolithic site of the lengyel culture in central Poland: Punishment,violence or mortuary behaviour?

During excavations at the Early Neolithic site of the Brześć Kujawski Group of the Lengyel Culture in Osłonki (central Poland), an atypical burial of an adult male was discovered. The individual's skeleton revealed traces of several perimortem injuries: both broken shins (the right shin with two fractures), a large fracture to the frontal bone and about 25 cut marks made with a flint blade in the parietal‐occipital region of the cranium on the left side. The arrangement of the fractured parts of the lower limbs might suggest that the injuries were intentionally exposed. Due to the relatively rich grave goods, it seems unlikely that the buried person was rejected by the community and thus killed or stigmatized by mutilation of the cadaver. The way the cuts were made is different from the cases of scalping or severing muscles in cannibalistic or mortuary practices known from the literature. This burial probably reflects some special funerary rite, which is now difficult to reconstruct or interpret. It is both possible that the observed injuries resulted from wounds that led to the individual's death (perhaps in circumstances that motivated the other special features of the burial) or that they were inflicted on the dead body. Taking into account the probable practices of dismembering of the dead body or human sacrifice found in the later Neolithic period in Poland, all of these possibilities may be considered with respect to this burial.

Could woodworking have influenced variation in the form of Acheulean handaxes?

The relationship between tool form and function is fundamental to hominin behaviour and evolution. Acheulean handaxes are known for their general consistency across more than a million years and three continents, albeit with some variation in size and shape. However, the influence of this variation on cutting has only rarely been studied, mostly in either butchery or generalized cutting tasks. Yet evidence indicates that handaxes were used for woodworking by at least 1.5 mya. Here, we experimentally tested whether woodworking could have exerted selective pressures on handaxe form. Additionally, these data were compared with a previous experiment that tested flakes during woodworking. For handaxes, no significant relationships were detected in woodworking efficiency. Accordingly, woodworking likely did not exert strong selective pressures on handaxe variability. However, the effectiveness shown by handaxes further demonstrates the functional flexibility of this technology, which is likely a factor contributing to their use over broad temporal, geographical and ecological spans. When comparing handaxes with flakes, only the smallest flakes were found to be significantly less efficient than handaxes. Therefore, the functional demands of woodworking were likely influencing hominin technological decisions about flake morphology, or the selection of flakes for woodworking, more than they were handaxe morphology.     

Oldowan reduction sequences: methodological considerations

Transport of resources is a major feature of Oldowan hominin technological adaptations. Comparisons between different Oldowan localities often employ measures of transport that are based on artefact attributes as proxies for the intensity of raw material utilization. The Technological Flake Category system [Toth, N., 1985. Oldowan reassessed: a close look at early stone artifacts, Journal of Archaeological Science 12, pp. 101–120] has been used extensively to infer the relative intensity of lithic reduction within Oldowan assemblages. Here we use a large experimental sample to test the relationship between a flake's stage in a reduction sequence and various quantitative attributes. We demonstrate how many previously described attributes are affected by initial core size. We then develop a multiple linear regression model that incorporates several variables to predict the placement of a flake within a generalized reduction sequence. The model is then applied to Oldowan assemblages in the Koobi Fora Formation which explores the strengths and weaknesses of different methods of investigating reduction intensity on an assemblage level.     

The Clactonian Question: On the Interpretation of Core-and-Flake Assemblages in the British Lower Paleolithic

In recent years, the nature, significance, and validity of the British core-and-flake assemblage known as the Clactonian have come under close scrutiny. More traditional ideas, which see the Clactonian as the product of a distinct, non-handax-making technical tradition, are being challenged by notions of a single European knapping repertoire in which the proportion of handaxes varies according to factors such as activity facies, local raw material potential, and landscape use. Furthermore, recent technological studies which show a basic technological parity between the Acheulean and the Clactonian, including claims for rare atypical bifaces within the Clactonian, have been argued as eroding the very rationale for seeing the Clactonian as a separate entity. These challenges have gained widespread acceptance, despite a lack of empirical support in some cases, questionable conclusions, and hints of a widely ignored, yet intriguing chronological recurrence. A review of the empirical basis and interpretation of the Clactonian, in both recent years and the recent past, suggests that the Clactonian is in danger of being explained away, rather than explained.     

Technology based evolution? A biometric test of the effects of handsize versus tool form on efficiency in an experimental cutting task

The use of stone cutting tools opened a novel adaptive niche for hominins. Hence, it has been hypothesised that biomechanical adaptations evolved to maximise efficiency when using such tools. Here, we test experimentally whether biometric variation influences the efficiency of simple cutting tools (n = 60 participants). Grip strength and handsize were measured in each participant. 30 participants used flint flakes, while the other 30 used small (unhafted) steel blades. Variations in basic parameters of tool form (length, width, thickness, cutting edge length) were recorded for the 30 flint flakes. It was ensured that mean handsize and strength in each participant group were not significantly different to investigate the effect of tool variation. The experimental task required cutting through a 10 mm-diameter hessian rope. Cutting efficiency was measured using both ‘Number of cutting strokes required’ and ‘Total time taken’. Results show that both efficiency measures were significantly correlated with handsize using all 60 participants. However, no significant differences were found between the flake and blade groups in terms of mean efficiency. Nor was any significant relationship found between tool form parameters and efficiency in the flint flake group. We stress that our results do not imply that tool form has no impact on tool efficiency, but rather that – all other things being equal – biometric variation has a statistically significant influence on efficiency variation when using simple cutting tools. These results demonstrate that biomechanical parameters related directly to efficiency of use, may plausibly have been subject to selection in the earliest stone tool-using hominins.     

Levallois Lithic Technology from the Kapthurin Formation,Kenya: Acheulian Origin and Middle Stone Age Diversity

The earliest fossils of Homo sapiens are reported from in Africa in association with both late Acheulian and Middle Stone Age (MSA) artifacts. The relation between the origin of our species during the later Middle Pleistocene in Africa and the major archaeological shift marked by the Acheulian-MSA transition is therefore a key issue in human evolution, but it has thus far suffered from a lack of detailed comparison. Here we initiate an exploration of differences and similarities among Middle Pleistocene lithic traditions through examination of Levallois flake production from a sequence of Acheulian and MSA sites from the Kapthurin Formation of Kenya dated to ∼200–500 ka. Results suggest that MSA Levallois technology developed from local Acheulian antecedents, and support a mosaic pattern of lithic technological change across the Acheulian-MSA transition.Les premiers restes fossiles d’Homo sapiens sont rapportés d’Afrique aussi bien à des avec des outillages de l’Acheuléen final que du Middle Stone Age (MSA). La relation entre l’origine de notre espèce au Pléistocène moyen final d’Afrique et le changement majeur marquée par la transition Acheuléen-MSA est par conséquent un moment clé de l’évolution humaine qui a manqué jusqu’ici d’analyses comparatives détaillées. Nous nous proposons ici de commencer à explorer les différences et les similarités qui peuvent se faire jour au Pléistocène moyen dans les traditions techniques à l’examen des productions à éclats Levallois, dans une séquence de sites acheuléens et MSA de la formation de Kapthurin (Kenya), datée de 200–500 ka. Les resultants obtenus suggèrent que la technologie Levallois MSA s’est développée sur ce substrat acheuléen et renforce cette perception que l’on peut avoir d’une mosa?que de changements technologiques jalonnant la transition Acheuléen-MSA.     

Information obtained from the microscopic examination of cultural striations in human dentition

The surfaces of teeth from some fossil remains and archaeological samples have been examined by SEM, in order to study different types of cultural striations and to determine the archaeological information that these striations can provide. Different patterns of cultural striations are present in human samples from different sites and periods. Similar cultural striations can be interpreted in different ways, depending on the tooth in which they are present, their location in the tooth and their direction, regularity, number and width. The study of cultural striations can yield valuable information about different aspects of feeding behaviour, oral hygiene, patterns of cultural diffusion and manipulative work with teeth of past human groups. A close integration with other anthropological and archaeological data is needed and specific interpretations should be made in each case.     

Elephants and subsistence. Evidence of the human exploitation of extremely large mammal bones from the Middle Palaeolithic site of PRERESA (Madrid, Spain)

The archaeological site at PRERESA (Madrid, Spain) has been dated to 84 ± 5.6 ka by optically stimulated luminescence (OSL) (MIS 5a). An area 255 m² was excavated and 754 lithic pieces were recovered, as well as a large amount of micro and macro vertebrate remains, including proboscidean bones. The aim of this paper is to outline the results of the taphonomic study of these remains. The identification of cut marks on a number of the bones recovered strengthens the theory that the exploitation of extremely large mammals was more than just a marginal practice before the Upper Palaeolithic. Additionally, the identification of green-bone fractures and percussion marks confirm for the first time, that the bone marrow of these taxa was also consumed. Few other cases of this practice have been identified, firstly because obtaining this substance would not be an easy matter, and secondly because similar nutritional needs can also be met by the consumption of brain matter, which is easier to acquire.
