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.     

A History of Depressed Skull Fractures from Ancient Times to 1800

The story of managing depressed fractures illustrates how knowledge of proven value does not always get handed down. Celsus was the first to describe sensible management for depressed fractures. As he wrote in Latin this was forgotten. Galen’s Greek writings survived forming the basis of management until the sixteenth century. In 1517, Hans von Gersdorff published a formidable illustrated surgical text. One illustration depicts an instrument for elevating depressed bone fragments. It looked dramatic but could not work and its defects were finally defined in the eighteenth century. Ambroise Paré used a bone punch just as we do today, but no later surgeon mentions this, though the instrument was well known. Elements of chance, fashion, emotionally powerful illustrations, and perhaps stubbornness had a profound effect on management delaying rational treatment for centuries.     

Intrataxonomic variability in metapodial and femur bone density related to age in guanaco (Lama guanicoe). Zooarchaeological and taphonomical implications

The aim of this paper is to present new information about bone mineral density (BMD) variability in guanaco (Lama guanicoe), a South American wild camelid; while taking into account its ontogenic development. The importance of considering intrataxonomic variability in bone density related to age for constructing zooarchaeological indices and applying them to archaeological assemblages is also discussed. The results presented here were developed from a large sample of 46 metacarpals and 45 femurs of modern guanacos, ranging in age from ca. 6 months of gestation to 12 years. Bone structural densities were measured using a biphotonic X-ray densitometer, DEXA method, Norland EXCELL and the bone mineral content (BMC) of each scanned portion or complete element was divided by its volume, which was obtained independently by water displacement. Our results indicate that the bone density of each anatomical unit is highly variable, even among individuals of the same species. According to metacarpals data, age is an important factor affecting BMD. Moreover, our study shows that the density ranges of different skeletal elements can overlap, suggesting that it is not possible to predict that a certain element is always denser than another one. Finally, we present new evidence about the potential age-related taphonomic bias in faunal assemblages, indicating that meanwhile some skeletal elements show clear differences in their density between their fused and unfused state (metacarpal) other do not (femur).     

Implications of heat-induced changes in bone on the interpretation of funerary behaviour and practice

Bones submitted to heat experience structural and chromatic modifications. In particular, heat-induced bone warping and thumbnail fractures have been linked to the burning of fleshed and green bones – where the soft tissues have been removed from the bones soon after death – in contrast to dry bones. Those have been suggested as indicators of the state of the individual before being burned thus allowing inferences about the funerary behaviour of archaeological populations. A large sample of 61 skeletons submitted to cremation has been examined for the presence of both of these heat-induced features. Although uncommon, bone warping and thumbnail fractures were present in some of the skeletons demonstrating that its presence is not restricted to the burning of non-dried bones as generally believed. Rather than being an indicator of the presence of bones with soft tissues, bone warping seems to be more of an indicator of the preservation of collagen–apatite links which can be maintained on dry bones with low collagen deterioration. In addition, our results also do not confirm thumbnail fractures as an exclusive sign of the burning of bones with soft tissues. As a result, these heat-induced changes should be used with caution when trying to infer about the pre-burning state of an individual.     

Wild Boar (Sus scrofa) Teeth from a Female Burial in Yuzhniy Oleniy Ostrov,Northwestern Russia (c. 6200 cal BC) – Local Rarities or Transported Goods?

Tooth pendants of European elk, Eurasian beaver and brown bear are the most common artefact type in graves at Late Mesolithic Yuzhniy Oleniy Ostrov on Lake Onega, northwestern Russia. In one burial of a 20-35-year-old woman, 18 fragments of wild boar tooth pendants from at least five individuals were found. Wild boar was not a regular part of local fauna in the Mesolithic, and if these wild boars were hunted locally, they were very unusual game. These wild boar tooth pendants may also represent imported goods that came to Onega from a more southern area via exchange. It is also possible that the woman was not local but came from a region where wild boars were abundant and common game for Mesolithic people.     

Rib fractures in the archaeological record: a useful source of sociocultural information?

Investigation of palaeopathological fractures has been shown to provide important information on past societies. However, despite the fact that rib fractures are amongst the most commonly recorded types of fractures in archaeological bone, little attention has been paid to them. Although there will be sites with badly preserved ribs, making their study difficult, this will not always be the case. Recent clinical investigations have highlighted the potential significance of rib fractures with regard to morbidity and mortality, and their importance in relation to health is now appreciated. This study investigates rib fractures in 352 adults from St. Martin's churchyard, Birmingham, England. The crude prevalence of rib fractures was found to be 15.6% and the true prevalence rate 2.3%. The majority of the fractures occurred in males, and those buried in vaults were less likely to have a fracture than individuals from earth‐cut graves. In 11 individuals the fractures were healing at the time of death, and in these cases death was probably related to one of the complications that are frequently linked to fractured ribs. Certain types of accidents may have been linked to these more serious fractures, as 70% occurred in the same anatomical area. Other rib fractures were associated with pathological conditions, such as osteomalacia and osteoporosis. Overall, the study of the rib fractures in this collection provided valuable information that aided interpretation of the lifeways of individuals investigated. It is argued that where preservation permits, studies of fractures in archaeological bone should include ribs. Copyright © 2005 John Wiley & Sons, Ltd.     

Ascertaining an agent: using tooth pit data to determine the carnivore/s responsible for predation in cases of suspected big cat kills in an upland area of Britain

The identification of the involvement of a particular carnivore in the modification of bone assemblages concerns a number of fields of research including archaeological and palaeontological enquiry. Taphonomy provides a methodology by which bone assemblages can be analysed and interpreted and this is more often undertaken with archaeological or palaeontological assemblages. A taphonomic analysis is undertaken here in order to determine the perpetrator of predation attacks on domestic stock from a modern-day setting. Recently reported techniques using tooth marks preserved on bone surfaces made by known carnivores are successful at determining some class sizes of predators and are used here to determine the perpetrator(s). Although a class size of carnivore is readily identified by this methodology, a particular carnivore taxon is not. Tooth morphology and dental configuration are reported here as better criteria for identifying a particular taphonomic agent. Tooth pit dimensions are used here to identify the class size of carnivores involved, and tooth morphology and cusp spacing to suggest a medium sized felid and fox as taphonomic agents. The identification of the medium-sized felid may support observations and reports of alleged “big” cat kills in the area. The study has important implications for the interpretation of fossil sites where felids may have been involved in the modification of animal carcasses but are archaeologically invisible in terms of their fossil remains.     

An investigation of historical and archaeological evidence for age‐related bone loss and osteoporosis

A growing awareness of the problems caused by osteoporosis‐related fractures has led to increased investigation of the condition in past populations. The present study seeks to examine the ways in which osteoporosis‐related fractures may be explored through different approaches; modern clinical information, historical records of fractures and analysis of archaeological bone may provide fuller information on the condition. The three types of fractures upon which this study focuses are fractures of the femoral neck, Colles' fractures and vertebral compression fractures. The results of the investigation clearly demonstrate the way in which the various sources produce a slightly different picture of the condition. The archaeological significance of the different types of fractures was found to be the reverse of that which would be suspected in the light of information derived from historical sources and the clinical literature. To date vertebral crush fractures have been the most commonly found osteoporosis‐related fracture in archaeological material, but their significance to people in the past is likely to have been minimal. In contrast hip fractures have rarely been reported from archaeological bone material, but historical information makes it clear they were well known, and knowledge derived from clinical sources emphasizes the serious consequences of such a fracture for the affected individuals. The results indicate the value of undertaking a multi‐disciplinary approach where possible. Copyright © 2002 John Wiley & Sons, Ltd.     

Investigating the potential of micro-focus computed tomography in the study of ancient bone tool function: results from actualistic experiments

Many experiments have sought to recreate the types of damage that would be expected in ancient stone and bone weapon tips. This damage is usually presented as visible fractures or microscopic surface modification. Fatigue tests conducted on bovine bones, however, show the development of internal micro-cracks that result from stress, prior to actual breakage. In this paper I present the results of an experimental investigation of bone points subjected to a variety of activities. I assess the presence of microdamage using micro-focus computed tomography. The results show that two patterns of micro-cracks develop in bone and are best viewed in longitudinal section. Micro-cracks are a cumulative feature dependent on the amount of load applied and the duration of activity. When subjected to high enough loading rates, micro-cracks will merge together to eventually form a fracture. Although further tests are needed to confirm the exact point at which these fatigue fractures begin to form, micro-focus computed tomography has the potential to reveal whether an individual bone point underwent multiple or prolonged impacts and thus to elucidate the probable function/s of ancient pointed bone tools where no visible damage is apparent. Micro-focus computed tomography is a non-destructive and non-invasive procedure and therefore safe to use on archaeological artefacts.     

Epiphyseal fusion in brown bears: a population study of grizzlies (Ursus arctos horribilis) from Montana and Wyoming

This contribution presents results of a study of the timing of appendicular epiphyseal fusion in brown bears (Ursus arctos) based on the visual examination of 86 modern skeletons of grizzlies (U. a. horribilis) of known age and sex from the greater Yellowstone area, in the States of Wyoming and Montana (US). The timing of fusion in brown bears was compared with the (scant) information available for the black bear (Ursus americanus); both similarities and differences were found. It is still inconclusive whether the discrepancies stem from the methods of study (visual examination vs. X‐rays) or whether they reflect real difference in fusion ages. It is suggested that data derived from U. arctos can be used profitably to investigate mortality patterns of extinct bears such as the cave bear Ursus spelaeus.

Carcass damage and digested bone from mountain lions (Felis concolor): implications for carcass persistence on landscapes as a function of prey age

This actualistic study examines the taphonomic signatures of modern free-ranging mountain lions (Felis concolor) on prey skeletal remains left at kill sites and digested bone fragments in the lions’ scats. Conducted in western Texas and southeastern New Mexico (U.S.A.), the study and its outcomes are relevant to models of carcass persistence and scavenging opportunities on ancient landscapes. Mountain lions in the study area ingested disproportionate quantities of bone from very young prey. This tendency holds true irrespective of prey body size. The results meanwhile confirm a relatively mild pattern of damage to adult deer carcasses. Digestive erosion of the surfaces of bones that passed through the gut was relatively severe, but many of these bone and tooth specimens retained identifiable features. It is clear that the mountain lions quickly remove the carcasses of very young prey from the pool of potentially scavenge-able resources. The non-linear relation between bone destruction from feeding by the cats and the skeletal maturity of prey also has consequences for prey mortality patterns, specifically a bias against the representation of very young individuals. This effect is not sufficient, however, to produce a global bias to prime-adult prey because older juveniles are much less affected.     

Gazelle bone marrow yields and Epipalaeolithic carcass exploitation strategies in the southern Levant

We measure the bone marrow yields of mountain gazelle (Gazella gazella) carcasses to reconstruct gazelle exploitation strategies during the Epipalaeolithic periods in the southern Levant. We present experimentally derived data on the bone marrow content of seven fresh gazelle carcasses, determine the range of marrow yields among individuals of different sexes and seasons of death, and compare the new data to gazelle skeletal element abundances from five Epipalaeolithic assemblages from Israel. We found extensive variation in marrow fat content among individual gazelles. Animals with the highest marrow yields were killed in the spring while animals killed in the early autumn had lower fat contents. Nevertheless, our results suggest that gazelle marrow provided a reliable, albeit small fat resource for prehistoric foragers in all seasons. Strong relationships between bone fragmentation and marrow content demonstrate that Epipalaeolithic people preferentially processed bones with high marrow yields.     

Europe as a global actor: empire by example?

The European Union (EU) spreads its norms and extends its power in various parts of the world in a truly imperial fashion. This is because the EU tries to impose domestic constraints on other actors through various forms of economic and political domination or even formal annexations. This effort has proved most successful in the EU's immediate neighbourhood where the Union has enormous political and economic leverage and where there has been a strong and ever‐growing convergence of norms and values. However, in the global arena where actors do not share European norms and the EU has limited power, the results are limited. Consequently, it is not only Europe's ethical agenda that is in limbo; some basic social preferences across the EU seem also to be unsustainable. Can Europe maintain, let alone enhance, its environmental, labour or food safety norms without forcing global competitors to embrace them? The challenge lies not only in enhancing Europe's global power, but also primarily in exporting rules and norms for which there is more demand among existing and emerging global players. This means that Europe should engage in a dialogue that will help it to establish commonly shared rules of morality and global governance. Only then can Europe's exercise of power be seen as legitimate. It also means that Europe should try to become a ‘model power’ rather than a ‘superpower’, to use David Miliband's expression. The latter approach would imply the creation of a strong European centre able to impose economic pains on uncooperative actors. The former would imply showing other actors that European norms can also work for them and providing economic incentives for adopting these norms. To be successful in today's world, Europe needs to export its governance to other countries, but it can do it in a modest and novel way that will not provoke accusations of ‘regulatory imperialism’.     

Networked Spirits and Smart Séances: Aura and the Anthropological Gaze in the Era of the Internet of Things

2015 has been declared the year of the “Internet of Things”, the promised (or threatened) era when our commodities communicate among themselves. But even the most optimistic prognostications cannot conceal deep ambivalences about objects and agency. How do we think about our things when they communicate and act independently of us? How do we frame our relationships with them? How do we articulate distributed intelligence? And how are others imbricated in those relationships? Yet, anthropologists have been asking these questions for some time, and, in this essay, I revisit some ghosts of anthropology's past in order to prompt spectral evocation of these anthropological futures. Through revisiting anthropological fascinations with the nineteenth-century séances, phantasmagoria, commodities and auras, this essay looks to nineteenth-century confusions not only to reflect on the confusions of the present, but also to gesture to possible futures where our lively things might help us challenge suspect dichotomies of human and non-human.     

Bringing the tracker-guards back in: Arms-carrying markets and quests for status in conservation at war

Scholarly attention to the militarization of conservation efforts globally is now being further explored through attention to the specific dynamics around “green militarization” in places where violent conflict is endemic, as in this special issue. Scholars have tracked the governance and economic effects of these developments. In this paper we look at a different level of political effect, namely that of individual tracker-guards as they navigate their careers in arms-carrying work. Existing research on tracker-guards focuses on them in their capacity as anti-poachers and looks at one site only. In contrast, we take a biographical, historical, and regional approach to show how anti-poaching jobs play into broader markets for arms-carrying work and the ways that men navigate them in search of social status and employment stability. The paper spans two adjacent but nationally distinct sites: eastern Chad (primarily in and around Zakouma National Park) and northeastern Central African Republic (primarily in and around Bamingui-Bangoran and Manovo-Gounda St. Floris National Parks). Focusing on the lives of three tracker-guards, we show that even within the same region the status and relational opportunities associated with anti-poaching vary depending on wider contexts encompassing evolving demands for skilled men in arms, and as a result so do the trajectories of people trying to make their way professionally in these realms. This finding demonstrates the usefulness of understanding the personal politics (social and relational factors and what counts as success) into which anti-poaching work plays.     

Age-dependent cortical bone loss in a medieval population

Age-dependent cortical bone loss was studied in a skeletal assemblage from a British medieval site using metacarpal radiogrammetry. Significant loss of bone was found in the females but not in the males. The magnitude of bone loss in the older females relative to their younger counterparts was found to be similar to that reported for modern European subjects. Low cortical bone was associated with healed fractures of the highly trabecular bone of the axial skeleton, and this observation is suggestive that weakening of the skeleton due to loss of bone substance precipitated such fractures, as it does in modern Western women. The broad similarities between the medieval and modern data may call into question the importance of lifestyle factors in influencing the severity of osteoporosis, at least as far as loss of cortical bone is concerned.     

Fur-Trade Period Animal Ceremonialism at the Grand Village of the Meskwaki

The Bell site was the principal village of the Algonquian-speaking Meskwaki from ca. A.D. 1680 to 1730. Based on collected ethnohistoric data, it is hypothesized that the Meskwaki saw bears and dogs as spiritually important animals and expressed this view through differential treatment of their remains. The results suggest that discard behaviors for bears were unique and that their remains may be indicative of ritual feasting. Meanwhile, comparison of features with dog remains to features with bear remains does not show clearly comparable behaviors in most cases. Ethnohistoric and ethnographic data suggest that dogs played an important role as spiritual conduits for the Meskwaki and their neighbors, but the archaeological data are not unequivocal.     

Trauma and amputations in 19th century miners from Kimberley,South Africa

Trauma is the result of violent accidental or therapeutic events that cause physical or psychological injury. The frequencies and types of trauma within a population can give important information regarding their lifestyle as well as the quantity and quality of medical care available to them. The purpose of this study was to assess the incidence of trauma in the Gladstone sample population with regards to the presence of interpersonal violence a hazardous working environment strenuous working requirements and the availability of medical care. The individuals studied here were diamond miners from Kimberley dating to the late 19th century. A total of 107 well‐preserved skeletons were excavated from unmarked graves after accidental discovery. This sample included 86 males 15 females and 6 individuals of unknown sex. The majority of individuals (71%) were between 19 and 45 years of age. The remains were most likely those of migrant mine workers of low socioeconomic status who had passed away at the local hospitals. All bones were visually assessed for macroscopic indications of traumatic bone alterations and compared to standard palaeopathological texts and photographs. A total of 27% (n = 28) of the individuals in the sample presented with well‐healed healing or perimortem fractures. Fractures to the skull encompassed 49% (n = 20) of all the fractures that were observed. A total of six (6%) amputations were noted. Spondylolysis was observed in 7% (n = 7) of the individuals within the sample and longstanding subluxation was noted in two individuals. The high incidences of cranial fractures within this population are suggestive of high levels of interpersonal violence while long bone fractures spondylolysis and evidence of longstanding subluxations are indicative of the strenuous work requirements and the high‐risk environment to which these individuals were exposed. When considering the presence of well‐reduced fractures and healed amputations it seems that adequate medical care was available to at least some members of this community.

Neoliberalism and the Institutions for Regional Development in Australia

This paper examines some effects of the pursuit of neoliberalism on regional development policy and practice in Australia, and in particular on the activities and effectiveness of regional development organisations. The paper interprets data from a survey of 505 regional development organisations across Australia through the framework of Jessop's contribution to state theory and his identification of four key trends in economic management under neoliberalism. Regional development policies are seen as a response of governments to electoral pressure from regions, but a response that is constrained by the dominance of neoliberal ideology. The objectives of regional development are predominantly economic, but are often limited to the role of facilitation and the provision of information. Some responsibility for regional development has been shifted downwards to regions, but the effectiveness of the organisations given this responsibility is reduced by the short‐term and competitive nature of much of their funding, the lack of coordination between regional development actors at the local level, the proliferation of agencies and the competition between them. The paper concludes that regional development agencies in Australia are in many ways a product of neoliberalism, since they represent one way in which governments can be seen to be responding to regional pressure for assistance but they can do so without incurring significant costs. Yet regional development bodies are also a victim of neoliberalist thinking, since it denies them the resources and the powers they need to be more successful in their work.
