Bone frequencies: differential transport, in situ destruction,and the MGUI

Human transport of bones with high food values, and destruction of bones with low density values are the traditionally invoked explanations of the frequencies of bones in archeological contexts. The manner in which these two explanations have been used suggests archaeologists assume the explanations to be independent of one another. The transport explanation is operationalized as the modified general utility index (MGUI) of Binford, and the destruction explanation is operationalized with measures of bone density. Statistical correlation of the MGUI with bone density, while weak, indicates that many high utility bones have low density values while many low utility bones have high density values. Because low density bones tend to be destroyed more readily than high density bones, inferences of human utility strategies derived from bone frequencies and based on the MGUI may be inaccurate. The utility strategies suggested by three archaeofaunas are compared to bone density, and two of these faunas are shown to potentially be the result of differential destruction and not human transport as measured by the MGUI.     

Osteophagia and dental wear in herbivores: actualistic data and archaeological evidence

The ability of herbivores to produce damage in bones and antlers has recently been described by the present authors (Cáceres et al., 2011), showing several cases of modified bones and various stages of bone modification due to osteophagic behavior by herbivores. Herbivores chew and eat bones and antlers to make up for mineral scarcity in their diet. In this paper we describe how the consumption of bone and antlers by herbivore can result in distinct differential tooth wear, breakage and the loss of some dental pieces. This damage has also been identified in fossils. These preliminary results are especially relevant in archaeological contexts, because this marked tooth wear can be mistaken for dental disease or lead to the incorrect assignment of age to the animals.     

Three-hole composite stone anchors from a medieval context at Caesarea Maritima,Israel

Three-holed stone anchors have been considered the earliest ‘composite anchors’, replacing single-hole ‘weight anchors’ of the Bronze Age. Though there is inconclusive evidence as to the first appearance of this new, revolutionary type, the data from land sites attest its use by the end of the 13th century BCE. Specimens of this anchor have been used as a testimony for Iron Age maritime activity of the Phoenicians and related maritime groups at various sites. While three-holed stone anchors were found in clear medieval contexts, only a few originate from good datable contexts. Recent discoveries derive from both the well-stratified medieval urban settlement of Caesarea, and late deposits on its harbour floor. They include the period between 1101 and 1265, when Crusaders settled in the city. This data calls for a revision of our attitude towards ‘anchorology’ and a reassessment of earlier conclusions concerning typology as a cultural and chronological benchmark.     

A Day’s Excursion among the Churches of South-East Norfolk

It will be proposed that the common utilitarian or functional explanation for the deposition of currency bars is too simple and should be amended to allow greater emphasis on the social context of the acts of production and deposition. Research indicates that currency bars—both as single finds and as hoards—occur in a limited range of archaeological contexts. It would appear that the act of deposition occurred under strict control and that the majority of currency bars were deposited as part of acts of ritual. The archaeological contexts of the three major types of currency bar are considered. All three types of currency bar—spit-shaped, sword-shaped, and plough-share—occur in similar contexts. Two major types of context are identified and in turn these define at least two distinct regions in the distribution of the bars. One zone is characterized by the deposition of the bars in varying sized hoards, but almost always in close relationship to a hill-fort rampart or a settlement boundary ditch. This may relate to rituals which defined the boundary of the settlement area of the family or community group. The analysis raises questions concerning the social and ritual significance of the boundaries which surrounded iron age hill forts and settlements. In contrast, a second zone is characterized by the deposition of currency bars in a range of natural locations (including bogs, rivers, caves, and rocky outcrops) which constitute the more standard contexts of ritual deposition for the British Bronze Age and Iron Age. These contexts may relate to rituals that defined boundaries at a range of scales; from those between social groups to tribal boundaries and even the boundaries of Britain.     

The Use of Multiple Correspondence Analysis (MCA) in Taphonomy: The Case of Middle Helladic Asine,Greece

The goal of this paper is to investigate whether multiple correspondence analysis (MCA), a multivariate statistical technique, is a useful dimensionality‐reduction tool in zooarchaeological and taphonomic studies. For this purpose, the focus is to detect and discuss traces of waste management. Animal bones from waste‐related contexts at the Bronze Age site Asine, Greece, are investigated. The data consist of bone fragments dating to the Middle Helladic from this site. Unidentified fragments were categorised in size classes, where possible. Information on taxa, skeletal parts and the presence or absence of several taphonomic markers is included in the data set. The MCA reveals several correlations of zooarchaeological interest. For example, the association between indeterminate fragments and calcined bone points to issues concerning identification and preservation. Floors are characterised by weathered long‐bone fragments from medium‐sized mammals. Additionally, the results of MCA indicate that the material might have suffered from density‐mediated attrition, based on the abundance of axial fragments, which did not differ between different contexts and taxa. The results show that MCA can be used to detect zooarchaeological and taphonomic patterns. This multivariate technique is useful when investigating large data sets, as is often the case with large zooarchaeological assemblages. Copyright © 2016 John Wiley & Sons, Ltd.     

‘Rid grasse of bones’: A taphonomic study of the bones from midden deposits at the Neolithic and Bronze age site of Runnymede,Surrey, England

Runnymede has large samples of Neolithic and Late Bronze Age animal bones, with contrasting preservation conditions in both periods. The bone evidence has been used to interpret the formation of the site deposits. There are few articulated bones, and no joins were found in butchered bone, indicating that the area studied did not contain primary refuse. Various aspects of bone alteration have been analysed: (i) the proportion of bones with very good surface preservation was high in the in situ Neolithic excavation units and the basal Bronze Age midden, but bones in the upper units were mostly eroded. These units are reworked flood deposits. The greater degree of fragmentation of the bone in the reworked units has been quantified, using a system of recording the ‘zones’ present on each bone, which allows calculation of the fraction present. It is also demonstrated that the reworked units contain a lower proportion of identified bones and a higher proportion of teeth and iaws than the units with well-preserved bone, (ii) Quantification of canid gnawing shows, unexpectedly, that more was recorded on well-preserved bone. Thus recognition of gnawing depends on bone condition. This also confirms that most of the erosion of the bone surface is a post-depositional phenomenon. The sequence of activities is therefore interpreted as follows: meat was cooked and consumed, and the bones discarded for the dogs. At a later stage, larger bones were picked up and thrown away in the river or midden. Some ethnographic examples of periodic cleaning of farming settlements are cited.     

Her Mirror,His Sword: Unbinding Binary Gender and Sex Assumptions in Iron Age British Mortuary Traditions

At the site of Hillside Farm, Bryher, on the Isles of Scilly, a materially rich single Iron Age inhumation was discovered containing the unsexable fragmented remains of one adult with a number of high-quality metal grave goods including an iron sword with a bronze scabbard and a bronze mirror. Swords and mirrors have long been considered high-status, oppositionally gendered grave goods that crosscut regional divisions in the pre-Roman British Iron Age (c. 800 B.C.–A.D. 43). Their combined presence within the burial of a single individual represents a touchstone within the ongoing unraveling of a long-held, interconnected set of reified binary sex and gender assumptions that have permeated discussions of British Iron Age mortuary contexts. In better recognizing this web of “binary binds,” we can deconstruct the a priori, exclusionary, interconnected sex and gender assumptions that configure how we investigate the terms of engagement between materials and persons in these burial contexts. Crucial to this analysis is an approach to patterning that (1) does not begin with a search for sex and gender as evidence of male and female dichotomies, (2) sees the potentiality for any component of a mortuary assemblage to have multiple points of significance, and (3) embraces data ambiguity. Developing such critical approaches will ultimately contribute to the deployment of more inclusive forms of analysis that do not reify sex and gender as the primary organizing principles within mortuary contexts, aiding scholars in avoiding assumptions that bind sex and gender analyses into artificially binary paradigms.     

Identifying stone tools used in mining,smelting, and casting in Middle Bronze Age Cyprus

Abstract

Metallurgical production sites are often difficult to identify in the archaeological record because ore beneficiation and slag processing in the past involved the use of ground stone tools that were similar to those used in other contexts to prepare cereals and foods. Analysis of the ground stone assemblage from a Middle Bronze Age copper mining and production site at Ambelikou Aletri in Cyprus provided an opportunity to distinguish industrial and domestic ground stone tools and to identify the types of tools used in different stages of metal production. A comparison of tool morphologies, raw materials, and wear and breakage patterns from Ambelikou Aletri with those from contemporary domestic contexts, suggests that distinctions in the nature and structure of industrial and domestic tool kits do exist and those distinctions have an important role to play in identifying mining, smelting, and casting sites in the future.     

Separating Sheep (Ovis aries L.) and Goats (Capra hircus L.) Using Geometric Morphometric Methods: An Investigation of Astragalus Morphology from Late and Final Bronze Age Central Asian Contexts

Many qualitative and quantitative methods for the separation of sheep and goat bones are based upon Middle Eastern, Mediterranean and European specimens. However, these methods may not be as applicable in other geographical contexts due to regional morphological variation. In order to address this, both traditional and geometric morphometric methods were applied to sheep, (Ovis aries L.) and goat (Capra hircus L.) astragali from archaeological sites from Kazakhstan dating to the Late and Final Bronze Age (1900–900 bce ). This exploratory research confirmed that qualitative features remained useful for distinguishing between species, while traditional morphometric methods were unable to conclusively support the field identification of species. Geometric morphometric methods found significant morphological differences between species and confirmed group membership while exploring specific qualitative features that were effective in distinguishing between sheep and goat in Central Asian contexts.

Ceramics, Ethnohistory, and Ethnography: Locating Meaning in Southern African Iron Age Ceramic Assemblages

For ceramics to be relevant in the Southern African Iron Age, archaeologists must broaden their theoretical base to include social and other contexts when interpreting material culture items such as pottery. Pottery remains critical in understanding cultural dynamics in the region for the past two millennia, but current usage is narrow in scope. Using ethnohistorical data and archaeological examples from South Africa and Zimbabwe, we argue that pottery provides valuable information on the region's Iron Age, if archaeologists address the social meaning of ceramic assemblages. Ceramic production among rural communities provides the basis on which a wide range of social issues are discussed and used to critique pottery recovered from archaeology. Ethnography suggests that ceramic assemblages are context specific, and archaeologists are cautioned against making generic statements on the basis of similarities of vessel shape and decoration motif.     

The Nature and Function of Astragalus Bones from Archaeological Contexts in the Levant and Eastern Mediterranean

Worked and unworked astragalus bones from a variety of different animals have been excavated throughout the eastern Mediterranean and Near East in several different contexts. This paper examines the nature and function of astragali and their modifications, and concludes that they were most often used as gamepieces, but also served a ritual function in cultic and funerary contexts. The frequent use of astragali in ritual contexts is due to the manner in which animals were skinned, and as a result of cultural diffusion. The frequent occurrence of worked astragali in cultic and funerary contexts allows them to serve as potential indicators of ritual activity in archaeological excavations.     

Tracking changes in bone fracture morphology over time: environment, taphonomy, and the archaeological record

Zooarchaeologists have often employed studies of bone fracture morphology as a means of understanding past human cultural activity, and various methodological approaches have been developed for analyzing archaeological broken bone assemblages. It is widely understood that bones degrade over time, however, few studies have attempted to define and quantify the rate at which bones degrade and fracture morphologies change. This study examines degradation in frozen bones (−20 °C) and bones exposed to hot (40 °C) dry conditions. These two simulated environmental conditions represent extreme real-world climates, and allow for an actualistic understanding of the rates of degradation that bones experience in nature. When frozen, bones degrade slowly but significantly, and demonstrate measurable differences in samples frozen for 1, 10, 20, 40, and 60 weeks. In hot, dry conditions, bones degrade very quickly, and demonstrate measurable differences after 1, 3, 7, 14, and 21 days. These data allow for a more detailed understanding of the relationship between the cultural and natural processes that result in bone fracture, and the time period during which bones can be expected to maintain fresh fracture characteristics. This research also has implications for understanding human subsistence and survival strategies and for interpreting the archaeological record.     

Meaningful Materials? Bone Artefacts and Symbolism in the Early Bronze Age Aegean

The symbolically laden use of materials is well documented ethnographically but hard to demonstrate archaeologically, especially for animal bones and teeth, use of which in post‐Neolithic contexts is commonly considered expedient. Early Bronze Age southern Aegean mortuary assemblages have yielded three distinctive classes of bone artefact. Comparison with contemporary unworked bone assemblages and contextually or formally related objects in other materials reveals complex cultural associations, the symbolic meaning of which is explored through heuristic use of ethnographic analogues. It is concluded that alternative value systems operated alongside those structured around exoticism and technological sophistication, usually deployed to understand EBA southern Aegean cultures.     

Sugar Monoculture,Bovid Skeletal Part Frequencies,and Stable Carbon Isotopes: Interpreting Enslaved African Diet at Brimstone Hill,St Kitts,West Indies

Sugar production was so pervasive in the British West Indies during the 17th, 18th, and 19th centuries that provisions were regularly shipped to the islands from as far away as Europe and North America. Skeletal part frequencies of bovids from late 18th century enslaved African contexts at Brimstone Hill Fortress, St Kitts, indicate that sheep and goats were probably raised locally, but that many of the cattle bones were transported to the site as barrelled beef. Stable carbon isotopes in sheep, goat, and cattle bones confirm these interpretations. This, in spite of the fact that cattle remains from Brimstone Hill included numerous marrow bones that ostensibly were excluded from barrelled beef. It is concluded that marrow bones, while reportedly excluded from barrelled beef, may have been included in provisions destined for enslaved Africans in the West Indies.     

Burnt bones and teeth: an experimental study of color,morphology, crystal structure and shrinkage

Burnt osteological materials are one focus of interest in forensic, archaeological, and palaeontological studies. We document the effects of experimental, controlled heating on a sample of modern bones and teeth from sheep and goats. Four aspects of heating specimens to between 20 and 940°C were considered: color, microscopic morphology, crystalline structure and shrinkage. Our results show that changes in both color and microscopic morphology of burnt bones and teeth can be divided into five stages each of which is typical of a particular temperature range, although the stages based on color do not correlate exactly with those based on micromorphology. These stages can be used to determine (1) if specimens of unknown taphonomic history were burnt, and (2) the maximum temperature reached by those specimens. In addition, powder X-ray diffraction studies show that heating causes an increase in the crystal size of hydroxyapatite, the major inorganic component of bones and teeth. This fact in conjunction with the microscopic morphology can be used to confirm deduced heating to 645°C or more. The data on shrinkage are analyzed to yield a polynomial expression that summarizes percentage shrinkage as a function of the maximum temperature reached by bones. Thus, the original size of specimens can be reconstructed within limits since the maximum temperature reached by the bones can be deduced on the basis of color, microscopic morphology and/or powder X-ray diffraction patterns. Finally, because there is a discrepancy between the maximum heating device temperature and the maximum specimen temperature, caution must be exercised in distinguishing between the effects of man made and natural fires.     

The Middle and Later Stone Age faunal remains from Diepkloof Rock Shelter,Western Cape,South Africa

The faunal sample from the Middle Stone Age (MSA) and overlying Later Stone Age (LSA) deposits of Diepkloof Rock Shelter (Western Cape Province, South Africa) includes at least 40 taxa, mostly mammals, but also tortoises, snakes, birds (especially ostrich represented by eggshell), and intertidal mollusks. The LSA sample contains only species that occurred nearby historically, including domestic sheep, which LSA people introduced to the region by 1800 years ago. In contrast, like other Western Cape MSA faunas, the Diepkloof MSA sample has more species and it is especially notable for five large extralimital grazing species. These imply a greater-than-historic role for grasses in the local vegetation, particularly in the post-Howiesons Poort (latest MSA) interval where the grazers appear most abundant. Extreme fragmentation and dark-staining impedes analysis of the MSA bones, but cut-marks, abundant burning, and numerous associated artifacts suggest that people were the main accumulators. Rare coprolites imply that carnivores could have contributed some bones, and concentrations of small mammal bones, particularly near the bottom of the MSA sequence, suggest a role for raptors. Tortoise bones are common throughout the sequence, and the MSA specimens tend to be especially large, as in other MSA assemblages. The LSA specimens are smaller, probably because LSA human populations were denser and preyed on tortoises more intensively. The most surprising aspect of the Diepkloof assemblage is its marine component. The coast is currently 14 km away and it would have been even more distant during much of the MSA when sea levels were often lower. Intertidal mollusks, particularly black mussels and granite limpets, are concentrated in the LSA and in the Late and Post-Howiesons Poort layers. Only LSA shells are complete enough for measurement, and the limpets are small as at other LSA sites. The implication is again for more intense LSA collection by relatively dense human populations. Both the LSA and MSA deposits also contain bones of shorebirds and Cape fur seals. Whale barnacles and occasional dolphin bones indicate that MSA people scavenged beached cetaceans.     

Burial containers – A hidden aspect of mortuary practices: Archaeothanatology at Ban Non Wat,Thailand

Research on mortuary practices has attracted a wide following for the role it can play in determination of individual social identity and population social structure. One aspect of mortuary practices that is rarely addressed, except where physical remnants are recovered, is the form of burial containers. Archaeothanatology is a taphonomically based methodology applied to infer the form of such containers when no material evidence remains. This paper shows how the archaeothanatological approach can be applied post hoc, with 133 adult burials from the prehistoric site of Ban Non Wat analyzed. Temporal changes in container form were expected as subsistence, technology, and social organization transformed over 1850 years. The deceased were predominantly loosely wrapped in non-durable material or placed in wide coffins, although individuals were buried in other contexts, with a peak in variety towards the end of the Bronze Age and early Iron Age. In combination with evidence from other sites in the area, our results identify a reduction in the variety of container forms used within sites in the mid to late Iron Age. We have shown the value of archaeothanatology as a contributor to research on mortuary practices, in particular having shown that it may be usefully applied post-excavation.     

Identification of dermestid pupal chambers on Southern Levant human bones: inference for reconstruction of Middle Bronze Age mortuary practices

Unique bone damage identified on Middle Bronze Age human skeletal material from the Southern Levant provided important information about the processes of modification and the possible funerary practices resulting in such damage. By comparing archaeological remains with recent skeletal material and by using computed tomography (CT) scans and 3D imaging techniques, the damage is interpreted as pupal chambers created by dermestid beetles. Using skeletal remains from two Middle Bronze Age sites, Jericho Tomb E1 and Munhata Tomb 641, we then discuss how the bores and tunnels left by dermestid beetles on human bones might constitute an interpretative key to the funerary practices of Middle Bronze Age collective burials.     

Birds and burials at Ajvide (Gotland,Sweden) and Zvejnieki (Latvia) about 8000–3900 BP

Animal bones in human burials may reveal aspects of the relationship between animals and humans. This article describes the roles of birds in mortuary practices and in the ideology of Stone Age northern Europe. Bird bones from two large burial sites, Middle Neolithic Ajvide (Gotland, Sweden) and Mesolithic and Neolithic Zvejnieki (Latvia) are investigated with osteological methods. Beads and pendants were fashioned from the wing bones of waterbirds, and used in the decoration of the body or the burial dress. The jay was found in three Neolithic burials at Zvejnieki, and it may have been a totem animal for the Middle Neolithic people at Zvejnieki, and its wings or feathers were presumably attached to dresses and costumes for the dead. Bird remains in burials at Ajvide, Zvejnieki and some other Stone Age cemeteries may indicate similar features in the way of perceiving birds, especially the possible symbolic roles of waterbirds and wings. The findings are discussed from the perspective of the cosmology of historical hunter–gatherer (and herding) groups in modern Russia.     

Transition from hunting to animal husbandry in Southern,Western and Eastern Finland: new dated osteological evidence

The beginning of animal husbandry in Finland is one of the most debated topics in Finnish archaeology. For this study a total of 69 bone materials from archaeological sites in Southern, Western and Eastern Finland, dating from the Middle Neolithic to the Early Metal Period, were analysed: 52 represented identifiable animal bones. These data were complemented with those from previously analysed bone materials. A total of 19 domestic animal bones were radiocarbon-dated to determine their connection with a particular cultural period. However, 13 of them proved to belong to the historical and not the prehistoric period, emphasizing the importance of radiocarbon-dating and context awareness when interpreting prehistoric bone materials. Among the radiocarbon-dated material were the oldest dated sheep, cattle and horse bones in Finland. The oldest radiocarbon-dated domestic animal bone in Finland, from sheep or goat, derives from the Late Stone Age Kiukainen Culture site, while cattle and horse bones date to the Bronze Age. This is later than expected. However, the available material does not exclude the possibility that some animal husbandry was practised in Finland earlier. Nevertheless, domestic animal bones are rare in samples dated to the cultural periods studied, while hunting and fishing represented important subsistence activities.
