Skeletal manifestations of vitamin D deficiency osteomalacia in documented historical collections

The frequency with which changes related to vitamin D deficiency are recorded in juvenile bone from archaeological contexts makes it clear that conditions conducive to such deficiency were fairly widespread at a number of points in the past. Although changes will take longer to be manifest in the adult skeleton than in juveniles, and may not be as obvious, the scarcity of reported cases suggests that it is likely that cases of osteomalacia are being overlooked in archaeological human bone. Vitamin D is probably better described as a hormone, rather than a vitamin, and the production of vitamin D within the body following exposure to sunlight allows adequate mineralisation of bone to take place. Lack of exposure to sunlight, which can be caused by a range of factors, is probably one of the main causes of vitamin D deficiency. The result of such a deficiency is a general weakening of the skeleton. The range of skeletal changes recorded across different bones of the skeleton in two documented historical pathology collections (the Galler collection, Basel, and the collection of the Federal Museum for Pathological Anatomy, Vienna), are discussed for scapulae, vertebrae, ribs, sterna, pelves and femora. The likelihood of each feature being preserved in archaeological skeletal material is considered. Although the changes associated with osteomalacia may lead to fragmentation of the skeleton, the presence of characteristic changes on bones from across the skeleton should make the condition identifiable using macroscopic examination, even where the skeleton is not well preserved. The identification of cases of osteomalacia in archaeological skeletal material is potentially significant because of the socio‐cultural information that can be implied from diagnosis of the condition.

A summary of epiphyseal union timings in Bosnian males

Dry bone documentation of epiphyseal union times is scarcely represented within the literature due to the difficulties in obtaining large sample sizes of known‐age, juvenile osseous material. The identified missing from the recent conflicts in the former Yugoslavia has become a source for such a sample. This study investigates the union times of 26 epiphyses, in addition to union of the sternebrae, in 256 identified Bosnian males between the ages of 14 to 30 years. Progress of union was recorded by assigning each epiphysis to one of three phases denoting open, active or complete union. Age/phase distributions are provided for each of the epiphyses, as well as a summary table documenting overall age parameters. The results of this analysis not only increase the discipline's overall understanding of the timings of developmental changes, but will also assist in the process of age estimations, specifically within the Balkans.

Fusion status of the jugular growth plate: An aid for age at death determination

To assess the feasibility of the fusion (synostosis) status of the jugular growth plate as an age at death indicator, a series of 98 skulls of documented age and sex from the so-called ‘Utrecht collection’ was examined. Ages at death in the series ranged from 14 to 92 years. Only specimens that could be inspected bilaterally were taken into account. According to the few but conflicting data from the literature, fusion happens at 16–18 years, or starts at ca. 25 years of age. In our sample no fusions were seen before the age of 22 years. Unilateral fusions were found only in the age range 22–34 years. At ages above 34 years in females and above 36 years in males all jugular growth plates were fused bilaterally. These results indicate that examination of the fusion status of the jugular growth plate is of use in age at death determination.     

Developmental Osteology of Cross‐bred Red Junglefowl (Gallus gallus L. 1758) and the Implications for Ageing Chickens from Archaeological Sites

We document the developmental osteology of a captive population of cross‐bred red junglefowl (Gallus gallus L. 1758) that were slaughtered at known ages from 6 days old until they reached maturity and explore the relationships that exist between bone size, maturity, body weight and sex. In doing so, we contribute to the body of knowledge concerning developmental osteology in domestic fowl, which has previously focussed upon ‘improved’ breeds. Comparison with archaeological material demonstrates that regression equations developed from the study population to determine age from bone length measurements are unreliable, even when samples with similar mean size for adult birds are compared. However, greater understanding of the maturity of domestic fowl more ‘primitive’ than most comparative material available for study is used to assist in the assignation of three age classes—chick, immature and adult—and thus facilitate more nuanced analyses of age‐at‐death patterns in faunal assemblages.

Age‐at‐Death Estimates from a Disarticulated,Fragmented and Commingled Archaeological Battlefield Assemblage

Estimation of age‐at‐death is an important and challenging part of any investigation of human remains. Extensive research has been undertaken on this subject as demographic information contributes much to bioarchaeological and forensic work. Disarticulated, fragmentary and commingled human remains occur from a wide range of spatial and temporal contexts, and estimation of age‐at‐death can be particularly challenging in these collections. This study evaluated the impact of preservation on techniques that might be applied and their relative utility, using human remains from the site of the Smith's Knoll associated with the Battle of Stoney Creek, a War of 1812 collection from Ontario Canada with some supporting documentary evidence on age‐at‐death. Features assessed were the pubic symphysis, auricular surface and epiphyseal fusion in the innominate. An age‐at‐death estimate was produced for 16 out of 19 individuals considered; the highest minimum number of individuals (MNI) was 24 (right radius) from 2701 identifiable fragments. The pubic symphysis made no contribution to construction of a demographic profile, but as has been suggested previously epiphyseal fusion was useful in this respect. Results demonstrate that previous statements regarding preservation of the auricular surface and its utility in fragmented and poorly preserved collections need to be carefully evaluated. Although 129 fragments of innominate were recorded just one had an auricular surface and post auricular area that could be fully assessed. Transition Analysis was easier to apply than techniques developed previously, and findings from this study suggest that use of the forensic prior distribution could assist in assessment of battlefield assemblages. These results raise some valuable points that need to be considered in any future attempts to improve age‐at‐death estimates using the auricular surface, and important questions regarding expectations for estimation of age‐at‐death in disarticulated, fragmented and commingled collections of human bone.

Directional asymmetry in the human clavicle

The human right clavicle tends to be shorter than the left. A range of possible explanations can be advanced to account for this asymmetry. In the present work, clavicular morphology was studied in a medieval skeletal assemblage from Wharram Percy, England, with the aim of evaluating these competing explanations. At Wharram Percy, as anticipated, the right clavicle tended to be shorter. Patterns of asymmetry in curvature, robusticity, vascularization, and in the morphology of ligament and muscle attachment sites were also studied. The patterning in these data at Wharram Percy is consistent with inhibition of longitudinal growth of the clavicle on the dominant side due to lateral bias in mechanical loading, particularly in axial compression.

The Relationship Between Molar Wear and Age in an Early 19th Century AD Archaeological Human Skeletal Series of Documented Age at Death

Crown height of molar teeth was measured in a 19th century Dutch skeletal collection of known age at death. Results indicate an approximately linear relationship between crown height and age. A closer relationship between age and crown height exists for the mandibular than the maxillary molars. The mandibular molars wear at a faster rate than the maxillary molars. There is no evidence for any difference in wear rates between first, second and third molars. No effect on wear rate of ante-mortem loss of occlusal partner nor of dental caries could be detected. The rate of wear in the study material was markedly slower than that which characterizes most archaeological groups and the burials are drawn from a rather heterogeneous urban population; these factors mean that dental wear ageing would be expected to perform less well in this material than for most archaeological groups. Despite this, strong correlations were observed between molar wear and adult age at death; that this was the case despite circumstances unfavourable for its use supports the idea that dental wear is a reliable ageing technique for most archaeological skeletal material.     

Scanning electron microscope study of normal vertebrae and ribs from early medieval human skeletons

A method is described for the preparation of vertebral body and rib sections of archaeological context, for scanning electron microscopy (SEM). The specimens included in the present paper are macroscopically normal and are male and female in juvenile and adult age brackets. The changing directionality of trabeculae and the changing ratio of trabecular bone to cancellous space are noted in relation to the age at death.     

A juvenile human frontal bone from the French Upper Palaeolithic site of Lacave: significance and problems of interpretation

In 1902, a portion of a juvenile human frontal bone was excavated by Armand Viré from the cave of Lacave in the Dordogne valley of southwestern France. The specimen is clearly from an Upper Palaeolithic context, although problems in interpreting the stratigraphy and postdepositional history in the cave render it essentially impossible to determine whether it is from a Magdalenian or Solutrean context. The morphology of the specimen is modern, as would be expected considering its relatively late Upper Palaeolithic context. Examination of aspects of brow ridge and frontal sinus development, as well as metopic suture obliteration, allows estimation of a developmental age of approximately 7–8 years for the specimen. Sex is indeterminate, and there is no pathology present. Apart from serving as an example of the problems of interpreting fragmentary skeletal remains from early 20th century excavations, the Lacave frontal represents one of the relatively few subadult cranial specimens known from the European Upper Palaeolithic. As such it is a valuable addition to the fossil record of early modern humans from Europe. Copyright © 1999 John Wiley & Sons, Ltd.     

Inventing the Victorian age: the Greville Diary and its Early Critics

The Journals of Charles Greville, clerk to the Privy Council from 1821 to 1859 are among the most well-known, well-respected and widely cited sources for the political and social history of their times. What is less well-known is the controversy they aroused among Greville's Victorian readers when first published (less than a decade after Greville's death) in 1874. The purpose of investigation here is to chart the course and extent of reader reaction as it unfolded during 1874–75, to explore ways of accounting for its intensity and, finally, to attempt evaluation of its impact as a cultural experience conducive to the emergence among readers of a conscious recognition of themselves as ‘Victorians’. When read in the context of the preoccupations of its first readers, Greville's Journals prove to be anything but a dead historical source. Instead, reader reaction is found to be driven by a series of contemporary concerns. They include the question of the degree of respect owing to hereditary authority; the definition of standards of honourable behaviour in protection of the private dealings of people of public reputation; and the very degree of reliability to be attributed to diary-based ‘memoirs’, given their contestable genre. Even so, participants in the controversies which broke out on all these fronts found themselves admitting common ground in acknowledging across their differences that the ‘Victorian’ age in which they lived was a decisive cultural and political break from the past world the Journals recorded.     

Age‐at‐death assessment using the os pubis and the auricular surface of the ilium: a test on an identified Asian sample

This paper reviews the results of blind tests of two morphological methods of age‐at‐death estimation. These tests were performed on a known age‐at‐death and sex sample taken from a collection of a Thai population. The first technique is based on the age related changes of the pubic symphysis according to the Suchey‐Brooks system, and the other concerns the metamorphosis of the auricular surface of the ilium elaborated by Lovejoy and colleagues. This is the first time that these methods have been tested on skeletal material from Asia. The results indicate that, for both methods, bias and inaccuracy increase with age and true age tends to be underestimated. As a consequence, age‐at‐death assessment based on these two techniques should be avoided on Asian archaeological series or forensic cases. Copyright © 2004 John Wiley & Sons, Ltd.     

Developmental Stress and Survival among the Mid Upper Paleolithic Sunghir Children: Dental Enamel Hypoplasias of Sunghir 2 and 3

The Sunghir 2 and 3 late juvenile to early adolescent immature skeletons, from the Mid Upper Paleolithic (Eastern Gravettian) of northern Russia, exhibit several episodes of dental enamel hypoplasias. Those of the older male Sunghir 2 relate principally to a stress episode in the third year post‐natal, although subsequent minor stress episodes may be indicated. They are not accompanied by other marked developmental abnormalities. The younger female Sunghir 3 exhibits at least three episodes of pronounced post‐natal stress through the third to fifth years post‐natal, followed by femoral and tibial growth arrest lines that formed shortly before her death at 9–11 years. These first decade post‐natal stress episodes of Sunghir 3 may be related to the same developmental condition that produced her abnormally bowed femora pre‐natally and/or to continued frailty related to that condition. Surviving these stress episodes for different lengths of time, both Sunghir 2 and 3 were awarded the most elaborate Paleolithic burial known. Copyright © 2011 John Wiley & Sons, Ltd.     

Occipitalization of the Atlas in Archaeological Material from the 16th–19th Century

During the anthropological analysis of skeletal material dated in the 16th–19th century from St Katarina monastery in Split, a female skull with occipitalization of atlas has been found. Anterior part of atlas and foramen magnum were fused, with numerous perforations on auricular surface of atlas. As the age at death was estimated at more than 70 years, it is most likely that this woman had progressive course of illness. Copyright © 2012 John Wiley & Sons, Ltd.     

Combining photogrammetry and laser scanning for the recording and modelling of the Late Intermediate Period site of Pinchango Alto,Palpa, Peru

This paper describes the 3D modelling of Pinchango Alto, Peru, based on a combination of image and range data. Digital photogrammetry and laser scanning allow archaeological sites to be recorded efficiently and in detail even under unfavourable conditions. In 2004 we documented Pinchango Alto, a typical site of the hitherto poorly studied Late Intermediate Period on the south coast of Peru, with the aim of conducting spatial archaeological analyses at different scales. The combined use of a mini helicopter and a terrestrial laser scanner, both equipped with a camera, allowed a fast yet accurate recording of the site and its stone architecture. In this paper we describe the research background, the 3D modelling based on different image and range data sets, and the resulting products that will serve as a basis for archaeological analysis.     

Animal palaeopathology: Possibilities and problems

A brief account of the range of pathological disorders affecting the skeleton and certain other tissues of animals (mainly mammals) is given to indicate a broad picture of the sort of lesions which might be encountered in archaeological contexts.Though palaeopathological bone specimens have been described since the 18th century, it is only recently that an interest in archaeozoological material has encouraged the tentative interpretation of such specimens. Despite the pessimism of some workers in the field, it has been shown that this material does persist in archaeological samples, and that while diagnosis is not always clear cut, some of the spectrum of bone changes induced by disease processes has been documented.As early as 4000 years ago an awareness of some of these diseases was recorded, with several early societies adopting preventive and therapeutic measures to deal with them. As advanced human communities came into more intimate contact with animals, transmission of infectious diseases was facilitated. Husbandry practices, too, are seen to be directly related to the incidence of certain conditions, the occurrence of which in archaeological material can yield an insight into animal keeping.Diverse data of archaeological significance is, in fact, retrievable not only from osteological remains, but from organic material which may be preserved under certain conditions. The impact of animal disease is far-reaching, with important implications not only for the economy but also for human health.     

Measuring Root Dentine Translucency in Human Teeth of Varying Antiquity

Many workers have calibrated human root dentine transparency (RDT) as a linear regression on age. It is now regarded as a well-established means of estimating age at death in modern human material. Similar applications in archaeological material have not yet been developed. The aim of this study was to establish a standard protocol for measuring RDT which was derived from previous methods and which could be applied to teeth of unknown and varying antiquity. An initial study on two archaeological populations determined the choice of tooth to study and a second study, using expendable teeth (of unknown age and origin), evaluated various techniques of specimen preparation and examination. Findings from the pilot study indicated that the lower canine was the tooth of choice. From the second study it was observed that archaeological teeth could only be sectioned if they had first been infiltrated and embedded in methyl methacrylate. The optimal section thickness was found to be 150 μm and no benefit was gained by staining. Inter-observer reliability tests showed significant differences in repeated measures of RDT in intact teeth, which were not borne out when sectioned teeth were used. Intra-observer reliability was maintained for measurements in both intact and sectioned teeth. These findings have been used to establish a standard protocol for application to human teeth of any depositional phase to estimate the dental age at death of that individual.     

Micro‐CT Imaging and Analysis of Enamel Defects on the Early Late Pleistocene Xujiayao Juvenile

Dental pathologies and enamel defects in East Asian hominins have rarely been reported. Here, we systematically document and describe a suite of enamel defects in the Xujiayao juvenile maxilla, an East Asian hominin from the early Late Pleistocene that may represent an unknown hominin lineage. In addition, we determine the chronology of growth disruptions represented by matched linear enamel hypoplasias, evaluate the long‐held hypothesis that the large brownish pit on the I¹ is evidence of dental fluorosis and assess the utility of micro‐computed tomography (micro‐CT) techniques in analyzing enamel defects. With the use of binocular microscopy, scanning electron microscopy (SEM) and micro‐CT imaging techniques, the Xujiayao teeth were found to exhibit a high number of pit‐form defects seldom seen in the fossil record. By matching the timing of linear enamel hyperplasia across multiple teeth, a minimum of five developmental disruptions were identified, indicating that the Xujiayao juvenile experienced several growth disturbances during its short lifespan. Our SEM and micro‐CT analyses suggest that the large pit on the I¹ is an enamel hypoplasia due to its morphology and pre‐eruptive enamel thinning. It is not a post‐eruptive fluorotic pit, and there is no evidence of chalkiness or opacity associated with dental fluorosis. The micro‐CT technique made it possible to verify the presence of enamel hypoplasia and to more precisely quantify defect dimensions, especially in unerupted teeth and shallow hypoplasias that are difficult to detect by binocular microscopy or SEM.

Trajectories of Development: International Heritage Management of Archaeology in the Middle East and North Africa

Archaeology and material heritage are increasingly being used for development projects aimed at producing economic growth and reducing poverty. I am interested in how these projects construct particular ‘developmental’ visions of heritage, orienting and circumscribing relationships both with the past and contemporary social contexts. Here I address these processes as developmental technologies that produce poverty as a ‘local’ affair, in need of intervention, set in contrast to the traveling and translational abilities of international expertise in heritage management and development. I trace the expansion of this expertise across the Middle East and North Africa region, in a variety of contexts where material heritage is mobilized to reduce poverty. Importantly, the question of the economic value of heritage is necessarily placed center-stage in such projects. I argue that as archaeologists we need to engage with the economic value of material heritage, in order to start examining how exactly material heritage works in the world: to what ends and results, in what contexts, who gains to profit, and who suffers.     

Pronounced bilateral asymmetry of the complete upper extremity: a case from the early Neolithic Baikal,Siberia

An adult male skeleton from the early Neolithic cemetery of Shamanka II on the south coast of Lake Baikal (Siberia, Russia) presents one of most striking examples of upper limb bilateral asymmetry documented without obvious indicators of skeletal pathology or trauma to the afflicted arm. The condition is noteworthy not only for its severity, with asymmetry values as high as 89.5%, but also for its involvement of the whole upper extremity, from clavicle to manual phalanges. The lack of any demonstrable hypertrophy on the unaffected left arm, and the clear evidence of extensive hypotrophy/atrophy on the right, leave little doubt that this asymmetry has a pathological or traumatic basis rather than a functional (activity‐induced) one. It most likely reflects paralysis or paresis of the entire right arm resulting from complete brachial palsy incurred prior to the attainment of skeletal maturity in that limb.

Clarifying prehistoric parasitism from a complementary morphological and molecular approach

This paper reports an approach to the identification of prehistoric parasitic infection, which integrates traditional morphological methods with molecular methods. The approach includes the strengths of each method while mitigating the limitations. Demonstrating the efficacy of this approach, we provide a case study from a 1400 year old desiccated fecal sample from La Cueva de los Muertos Chiquitos, archaeological site, near Rio Zape, Durango, Mexico. Traditionally prepared microscope slides were processed via microscopy and tentative ascarids were identified. Information regarding the parasites' developmental stage was recorded. DNA was then extracted directly from the slide material. From this DNA extract, a small segment of the 18S ribosomal RNA gene variant that is specific to Ascaris, and its phylogenetically close relatives, was targeted for PCR amplification and sequencing. Phylogenetic analysis of the DNA sequence best matched a member of physalopterids, rather than ascarids, with a single exception of a match to Contracaecum spiculigerum. Subsequent extractions, amplifications and sequencing of the original rehydrated coprolite material confirmed these results. The C. spiculigerum sequence represented a phylogenetic anomaly and subsequent analysis determined the sequence was an error in the BLAST database, likely attributable to misidentification of juvenile specimens prior to sequencing and submission. Physaloptera are a difficult genus to identify morphologically and can carry major health burdens. They may be underreported in humans, in part, because of morphological similarities to the more common human parasites belonging to ascarids. We conclude that integrating traditional morphological methods with molecular methods can help resolve this issue, in both contemporary and prehistoric populations.
