Which Bone to Pick: Creation,Curation, and Dissemination of Online 3D Digital Bioarchaeological Data

A fluorescence of shape-capture technologies at many different scales, including synchrotron, CT, micro/nano-CT, laser scanning, and photogrammetry, has led to a proliferation of digital data in bioarchaeology. The question remains how these new 3D datasets, alongside traditional bioarchaeological data, can be disseminated, and what ethical concerns are raised by trying to bring a sensitive topic into the ‘Open Access’ era. A survey of current resources and policies suggest the need for establishing best-practice standards. This paper outlines a sample of current resources, alongside modes of access and dissemination strategies to develop a picture of online Digital Bioarchaeological Data (DBD) use.     

Models and Metadata: The Ethics of Sharing Bioarchaeological 3D Models Online

Digital 3D modelling is increasingly common in archaeological recording, but building the models is only part of the story. Sharing and interacting with these digital representations is essential in fostering engagement and ensuring that research is relevant to the broader community. Projects and institutions understand that much of their communication and outreach now take place via digital platforms. However, archaeologists are faced with a variety of challenges when sharing 3D models of human remains online, including metadata curation, accessibility, openness, copyright as well as the ethical implications of sharing digital bioarchaeological data and long-term storage requirements. In this research, metadata from a collection of 3D models of human remains were extracted from SketchFab and analysed to understand how users share 3D models of human remains via online social platforms. The results were contrasted with a critical review of current ethical and technical guidelines, indicating potentially ethically compromising practices, particularly the lack of contextualising metadata for some models. This article proposes and discusses recommendations for developing more strategic approaches to the sharing of 3D data on human remains online, such as assessing and agreeing hosting, licensing and metadata management during project design. Frameworks are provided to support these approaches and make decisions on how to share data openly.     

Bioarchaeological Investigation of Possible Gunshot Wounds in 18th Century Human Skeletons from Korea

Notwithstanding the relative abundance of bioarchaeological evidence of pre‐20th century gunshot wounds discovered at European and American archaeological sites, similar findings in East Asian countries have been very rare. In this study, we report evidence of possible gunshot wounds sustained by two individuals buried in Joseon tombs of Korea. The shapes of the trauma seemed to indicate low‐velocity projectiles, most likely musket balls. To our knowledge, this is the first bioarchaeological report specifically concerning possible gunshot‐wound evidence in East Asian skeletons recovered from archaeological fields.

The Social,Spatial, and Bioarchaeological Histories of Ancient Oman project: the mortuary landscape of Dhank

The Social, Spatial, and Bioarchaeological Histories of Ancient Oman (SoBO) project has conducted three seasons of survey and excavation in north‐western Oman. Focusing on third‐millennium BC archaeological features, this project is unique because of the combination of geospatial survey and bioarchaeological excavation of mortuary monuments in and around the town of Dhank. Here we report our initial findings, define our survey area and techniques and discuss excavated funerary structures and associated radiocarbon dates from both charcoal and human skeletal remains. This report presents preliminary results that introduce this new project on the prehistoric mortuary landscapes of Oman and highlight the techniques the SoBO team employs to examine Bronze Age communities in this rural location.     

Bioarchaeological inferences from a Neolithic ossuary from Alepotrypa Cave,Diros, Greece

Alepotrypa Cave, one of the richest and best preserved Neolithic sites in Greece, was occupied by early farmers from ca. 5000 to 3200 BC . Study of human remains from this site contributes important information to the bioarchaeological record for this period. The remains are from the cave's Ossuary II, a secondary deposit containing the disarticulated remains of at least 20 individuals, including adults and sub‐adults. A high frequency of porotic hyperostosis and cribra orbitalia suggests the presence of chronic iron deficiency anaemia. A combination of two possible factors could explain this situation, including reliance on an iron‐deficient cereal diet, and presence of high pathogen and parasitic loads resulting from poor hygiene and contamination of the communal water source. These lesions may also be related to some type of inflammatory process. Some 31% of individuals display healed cranial depressed fractures, indicating evidence of violent (non‐lethal) confrontations. Stable isotope analysis reveals a predominantly terrestrial C₃ diet, with little evidence of marine food consumption, despite close proximity to coastal resources. The presence of various domesticated plants suggests that these C₃ foods may have been agricultural. Moreover, a high frequency of dental caries is consistent with a diet involving significant carbohydrate consumption. Copyright © 2000 John Wiley & Sons, Ltd.     

Teaching with Digital Archaeological Data: A Research Archive in the University Classroom

Digital tools and techniques have revolutionized archaeological research and allow analyses unimagined by previous generations of scholars. However, digital archaeological data appear to be an underappreciated resource for teaching. Here, the authors draw on their experiences as university instructors using digital data contained in the Digital Archaeological Archive of Comparative Slavery (http://www.daacs.org) to teach in a variety of higher education settings, from method-intensive thematic courses for graduate students to general education science courses for undergraduates. The authors provide concrete examples of how they use digital archaeological data to accomplish a range of pedagogical goals. These include teaching basic artifact identification and simple statistical methods as well as developing skills in critical thinking, inference from data, and problem solving and communication. The paper concludes with a discussion of how archaeologists can use digital data to address ethical and curricular issues, such as preservation, professional training, and public accountability that are crucial to the discipline and relevant to the academy at large.     

The 4.2 ka BP Climate Event in Egypt: Integration of Archaeological,Geoarchaeological, and Bioarchaeological Evidence

The 4.2 ka BP climate event was a phase of severe global drought. Its evidence has been attested in many regions of the world and was reported to have played an important role in the collapse of major ancient civilizations. This article provides a comprehensive literature review using several proxies on the 4.2 ka BP climate event in Ancient Egypt. It applies a multidisciplinary approach that integrates archaeological, geoarchaeological, and bioarchaeological evidence. The conclusion is that the event had critical environmental, economic, and political impacts. It led to aridification, a decline in the Nile level and Nile-fed lakes, encroachment of aeolian desert sand into the Nile Valley, lower crop yields, and famine across ancient Egypt. Therefore, as a compound event, it played an important role in the collapse of the Old Kingdom (ca. 2181 BC), and its effect continued in the First Intermediate Period (ca. 2181–2055 BC) when Egypt witnessed political fragmentation.

     

The Bioarchaeological Investigation of Childhood and Social Age: Problems and Prospects

Recently, the value of the study of children and childhood from archaeological contexts has become more recognized. Childhood is both a biological and a social phenomenon. However, because of specialization in research fields within anthropology, subadults from the archaeological record are usually studied from the biological perspective (bioarchaeology) or, more predominantly, the social perspective (social archaeology), with little research that incorporates both approaches. These polarized approaches to childhood and age highlight the dualistic way in which “biological” and “social” aspects of the body are viewed. Some recent literature criticizes bioarchaeological approaches, and calls for the incorporation of childhood social theory, including social age categories, into subadult health analysis. However, few studies have explicitly addressed the practicalities or theoretical issues that need to be considered when attempting this. This paper critically examines these issues, including terminology used for defining subadulthood and age divisions within it, and approaches to identify “social age” in past populations. The important contribution that bioarchaeology can make to the study of social aspects of childhood is outlined. Recent theoretical approaches for understanding the body offer exciting opportunities to incorporate skeletal remains into research, and develop a more biologically and socially integrated understanding of childhood and age.

A Bioarchaeological and Biogeochemical Study of Warfare and Mobility in Andahuaylas,Peru (ca. ad 1160–1260)

Warfare impacts how people and populations can move about the landscape. Ethnographers have posited that internal warfare, conflict that takes place within a single society, is strongly associated with female abduction. In contrast, external warfare, combat between different societies, is often accompanied by the in‐migration of men for purposes of defence. To test this assertion, we evaluate human remains from one of the most violent eras in Andean prehistory, the Late Intermediate Period (ad 1000–1400). In the south‐central highlands of Andahuaylas, Peru, this era witnessed the coalescence of two formidable polities, the Chanka and the Quichua. Ethnohistoric accounts describe internal warfare among the Chanka and external warfare between the Quichua and their neighbours. In this study, bioarchaeological and biogeochemical methods are marshalled to elucidate ancient patterns of violence and mobility with greater nuance. We employ strontium isotope analysis of tooth enamel apatite to inform on residential origin, and we reconstruct patterns of violent conflict through analysis of cranial trauma. In all, 265 crania were excavated from 17 cave ossuaries at two Chanka sites and one Quichua site. Data were collected on age, sex and cranial modification—an indicator of social identity and cranial trauma. A representative subsample of molars from 34 individuals subjected to strontium isotope analysis demonstrates that among the Chanka, violence was significantly directed towards social groups within society, marked by modified crania. The presence of two nonlocal women with signs of increased morbidity and mistreatment points to possible mobility‐by‐abduction. In contrast, among the Quichua, men have significantly more trauma, and wounds are concentrated on the anterior. Trauma on women is lower, nonlethal, and concentrated on the posterior. This divergent pattern is commonly observed in external warfare (raids and community defence), where men face attackers and women escape them. The presence of two nonlocal men supports a mobility model of strategic in‐migration. In sum, osteological and isotopic data sets are shown to reveal divergent life‐course experiences not captured by the archaeological data or historic records alone.

Bioarchaeological Analysis of a Royal Burial from the Oldest Maya Tomb in Palenque,Mexico

In 1957, a new discovery inside Temple XVIII‐A was made in Palenque, the Mayan archaeological site in Chiapas Mexico, a royal tomb of an original design which proved to be the oldest at the site. Two skeletons were found, the principal (PAL‐44) was at the centre showing red pigmentation on the surface of some bones, personal adornments and offerings, which indicate that he was an early ruler of Palenque. The second (PAL‐45), deposited at the entrance, not in a special mortuary position, without offerings, suggests it was of a lower social status. This research presents a new bioarchaeological analysis with the following results: (i) The result of a direct radiocarbon dating of PAL‐44 by accelerator mass spectrometry is 250–420 cal AD (LTL12759A:1696 ± 30 BP). This means that the personage was buried long before the first designated ruler of Palenque, who, according to the epigraphic record was enthroned in ad 431. (ii) With X‐Ray Fluorescence, the red pigment was identified as cinnabar (HgS). (iii) PAL‐44 is a young adult male with a severe idiopathic scoliosis with a double curvature that affected the ribcage and lower limbs. Such a three‐dimensional deformity resulted in changes to his body mechanics and induced motion asymmetry. Consequently, his health and mobility must have been significantly affected by such a severe condition. (iv) PAL‐45 is an adult female with signs of nutritional problems in childhood and entheseal changes probably related to her activity. Three ante‐mortem traumas are registered: rib fracture, frontal depressed circular fracture and a nasal septal deviation. This traumatic event took place two weeks, approximately, prior to PAL‐45's death. Copyright © 2013 John Wiley & Sons, Ltd.     

The Internet of Landlords: Digital Platforms and New Mechanisms of Rentier Capitalism

Digital platforms are a nearly ubiquitous form of intermediary and infrastructure in society. By positioning platforms in the geographical political economy/ecology literature, this paper provides a critical analysis of platforms as a dominant form of rentier in contemporary capitalism. In doing so, I extend this work on rent theory beyond applications to land and nature so that it also includes platforms and data. I argue that the rapid rise of the “X-as-a-service” business model across nearly all sectors of the economy is creating rentier relations by another name. This model is premised on the platform latching onto and inserting itself into the production, circulation, or consumption process, thus creating opportunities to capture value. To better understand the operations and implications of platforms, I outline three key mechanisms: data extraction, digital enclosure, and capital convergence.     

Virtual Representation: the Production of 3D Digital Artifacts

As new digital technologies now pervade the discipline of archaeology, the practice of creating digital 3D representations of artifacts has become widespread. The rapid growth and acceptance of these technologies into the discipline leaves us in a position where we must engage with how these tools fit our epistemologies. I propose that we look to a much older technology, photography, to inform the way that these digital artifacts are dealt with as we move into an increasingly digital field. In doing so, I will argue that the creation of a 3D digital artifact is a productive process, just as any form of media used to document and interpret the archaeological record. Through this production, the digital form is decoupled from the original physical artifact. The creation of a new representation of the artifact (in the form of a photograph or digital model) provides a new dimension to our interactions with these artifacts. The result of the digital movement in archaeology is a more interactive experience with artifacts, allowing researchers and the public alike digital access to archaeological collections. If the current trend continues, digital artifact modeling will become as indispensable to archaeology as traditional photography. It is therefore necessary for archaeologists to be aware of the subjectivities and biases that exist during this productive act as we move into a more integrated field of digital, representational technologies.

The Eulau eulogy: Bioarchaeological interpretation of lethal violence in Corded Ware multiple burials from Saxony-Anhalt, Germany

The Corded Ware is one of the major archaeological traditions of Late Neolithic Europe. Its burial customs are characterized by single graves but multiple burials also occur. We present a detailed study of antemortem and perimortem trauma in a group of Corded Ware skeletons from four multiple graves and give the most probable interpretation of the site, based upon all available bioarchaeological evidence. The pattern of observed injuries in male, female, and subadult skeletons, including cranial trauma, arrow wounds, and fractures of the forearm and hands points towards a violent event that resulted in the death of all individuals, most probably a raid. In contrast to comparable Neolithic raid sites, there was no complete extermination of the local population and no use of mass graves. The burials have been arranged with care and detailed knowledge about biological kinship ties [Haak, W., Brandt, G., de Jong, H.N., Meyer, C., Ganslmeier, R., Heyd, V., Hawkesworth, C., Pike, A.W.G., Meller, H., Alt, K.W., 2008. Ancient DNA, strontium isotopes, and osteological analyses shed light on social and kinship organization of the Later Stone Age. Proceedings of the National Academy of Sciences of the United States of America 105, 18226–18231]. The combination of clear causes of death and the proven biological relationships among some of the individuals, including a nuclear family, provides new and important insights into Corded Ware mortuary customs and the reasons why and how multiple graves have been utilised.     

DOES CRANIAL TRAUMA PROVIDE EVIDENCE FOR PROJECTILE WEAPONRY IN LATE IRON AGE DORSET?

Human remains form an independent dataset with which to examine martial activity in past societies, particularly how to understand the types of weaponry used and who was subject to lethal violence. In the Late Iron Age of Dorset (first century BC to first century AD), these data are useful in understanding such activity in light of the small range of extant evidence.
This bioarchaeological study examined the crania of 80 inhumed and articulated sexed adults, using forensic, bioarchaeological and clinical criteria to determine whether osteological evidence for sharp and blunt projectiles could be observed. The sample showed evidence for peri- and ante-mortem traumas, with the majority of injuries sustained at the time of death; most affected males and were caused by blunt projectiles. Healed injuries were observed in both sexes but only females had evidence for remodelled blunt projectile injuries. The age-groups affected were predominantly young and middle-aged adults, suggesting that weapon training began early in life.     

3D Digital Documentation,Assessment, and Damage Quantifi cation of the Al-Deir Monument in the Ancient City of Petra,Jordan

Abstract

The rock-cut monuments in the ancient city of Petra in Jordan form an outstanding tangible heritage site. Unfortunately, this important part of the world's cultural heritage is gradually being diminished due to weathering and erosion problems. In this research, an approach combining in situ surveying and laboratory analysis is applied in order to provide sufficient and comprehensive data regarding the documentation and evaluation of the status of the Al-Deir monument in Petra. The purpose was not only to quantify the damage, but also to make a first step towards creating a 3D monitoring programme of the deterioration rate. The approach presents a correlation study between the environmental condition and the surface weathering damage, using 2D mapping of the weathering form and accurate 3D realistic modelling from laser scanning and digital photogrammetry. The 2D mapping provides detailed weathering damage information for the entire stone surface of the monument, whereas the 3D modelling provides information on the spatial distribution and texture of the damage. Additionally, the 3D digital model can provide reference data as an exact guide to the restoration needed. In order to support the visual presentation of 3D surface details, a hybrid approach combining data from laser scanning and digital imagery was developed.

Studies of stone texture and spatial distribution of soluble salts were carried out at the monument in order to explain the mechanism of the weathering problem. Relative humidity, temperature, and wind are the main factors in the salt damage process. In order to study the effect of these conditions in the salt crystallization process a series of fieldwork investigations and laboratory work were undertaken. The results show that visible zoning of weathering damage is correlated to different salt concentrations.     

Who were the first urban settlers of Oslo? A discussion of early medieval urbanization based on isotopic analyses of human remains

This paper investigates the process of early urbanization in Oslo, Norway, during the initial period of early 11th–late 12th Century using a bioarchaeological approach. Through the use of isotope analyses performed on teeth and bone from 20 humans buried in Oslo during the first phases of urban settlement, individual dietary change and mobility are reconstructed. Oslo is traditionally perceived as one of many urban settlements initiated by royal power, and this paper contributes to this discussion by investigating the origin of the first settlers, and also how the early urban process affected their way of living. Results suggest that most individuals in the study were of local origin, and had a constant diet throughout life from childhood to its last phase. The absence of individual dietary change sharply contrasts the dynamic dietary patterns observed in people from the Viking age. Dietary variation between individuals does suggest, however, social differences among the early urban population of Oslo.     

Bioarchaeological Patterns of Violence in North Patagonia (Argentina) during the late Holocene. Implications for the Study of Population Dynamics

This work presents bioarchaeological patterns of interpersonal violence inferred for Northeastern Patagonia (Argentina) during the late Holocene. The main goal is to evaluate if there is a significant increase in the frequency of indicators of violence during the final late Holocene, prior to colonial times, in possible concordance with the Medieval Climatic Anomaly (ca. 1150–600 years BP). A sample of skulls (n = 797) was studied through a series of methodological steps that included the evaluation of their state of preservation and the study of potential injuries, taking into account the degree of ambiguity of the diagnosis. The sample was divided into three chronological groups: early (ca. 3500–2500 years BP), middle (ca. 2500–1500 years BP) and late (ca. 1500–400 years BP). The individuals were also separated according to sex, age category and geographical distribution. Although a temporal trend toward increased violence was detected, it was not statistically significant. There was also a higher percentage of positive cases in Northern individuals compared to the Southern ones, and between males compared to females, but neither case had statistically significant differences. Alternative mechanisms, such as population dispersals, exchange and use of buffer areas, that may have functioned to dispel social tensions, are proposed.

Stress near the start of life? Localised enamel hypoplasia of the primary canine in late prehistoric mainland Southeast Asia

Localised hypoplasia of the primary canine (LHPC) is characterised by roughly circular defective areas of thinned or missing enamel on the labial surface. This defect is rarely reported in bioarchaeological research. Using samples from late prehistoric mainland Southeast Asia, this paper documents the prevalence of LHPC to produce baseline data for this defect. The samples are from seven archaeological sites in Thailand and collectively span from ca. 4000 to 1500 BP. In the combined samples, 32/79 (40.5%) of individuals and 47/199 (23.6%) of teeth had LHPC. The high occurrence of LHPC may suggest there was poor maternal and infant health. There is also a high occurrence of caries associated with LHPC, which has implications for the assessment of deciduous dental health. This paper stresses the importance of the collection of dental enamel defect data from deciduous teeth including LHPC in bioarchaeological research.     

Digital heritage in a Melanesian context: authenticity,integrity and ancestrality from the other side of the digital divide

This article examines how digital heritage, in the form of 3D digital objects, fits into particular discourses around identity, ancestrality and cultural transmission in Melanesia. Through an ethnographic analysis of digital heritage use amongst the Nalik community in New Ireland (Papua New Guinea), it demonstrates how digital heritage is understood not in terms of deceit and a loss of authenticity, but instead, towards an understanding of authenticity in terms of completeness and integrity. A notion of completeness and integrity, I argue, has the effect of creating an authentic experience of the past for Nalik communities by bringing back museum objects (‘old’ objects) that have been dispersed amongst museums and heritage institutions worldwide. In tracing out the operations and effects of how a Melanesian community engages with 3D digital objects, this article offers unique ethnographic insights into digital heritage in ways that challenge widely-held assumptions about the heightened value placed on the original object over its digital counterpart.
