Neurocranial Trauma in the Late Archaic Human Remains from Xujiayao,Northern China

The early Late Pleistocene late archaic human remains from Xujiayao, northern China, reveal several abnormalities of the neurocranial vault. The Xujiayao site is located on the northwestern boundary of the Nihewan Basin, and on the basis of various indicators, it dates to the early Late Pleistocene. Among the 15 human neurocranial elements found at Xujiayao in the 1970s, three elements show minor traumatic lesions of the external table: the largely complete Xujiayao 5a immature parietal bone, the Xujiayao 8 small piece of anterior right parietal bone and the Xujiayao 12 partial occipital bone. The lesions are all superior to the temporal or nuchal lines and hence were subcutaneous, covered only by the pericranium, the galea aponeurotica and the overlying skin. The external tables are variably concave with irregular bone within the bony depressions, and the diploë show varying degrees of involvement. The Xujiayao abnormalities join a series of minor neurocranial healed lesions among Pleistocene humans, as well as more pronounced healed neurocranial and facial trauma.

Pathological Changes of the Cranium of a Young Female Cave Bear (Ursus spelaeus R.)—A Case Study (the Sudety Mts,Poland)

A cranium of a young female cave bear (Ursus spelaeus R.) was found in the Upper Pleistocene sediments of Bear Cave in Kletno, SW Poland. A detailed analysis of the cranium, including radiology, CT and histological methods, revealed numerous pathological changes caused both by diseases and by injuries inflicted by another predator. It is likely that during its lifespan, the young female was exposed to several attacks (bites on the head) from adult bears. The injuries varied in extent and caused bone infection and inflammation. The nature of most of them suggests that they were not fatal but could have had a significant effect on the overall fitness of the animal. In contrast, the lesions on the frontal bone and in the anterior part of the parietal bone may have been the cause of the individual's death. Additionally, the cranium was found to have cut marks, sharp‐edged longitudinal scars that indicate the use of a sharp‐edged tool, and are usually interpreted as effects of skinning. The finding is suggested to be indirect evidence of the existence of people in southern Poland during the Pleistocene. Copyright © 2012 John Wiley & Sons, Ltd.     

A Case of Early Childhood Caries from Late Roman Ancaster,England

This paper presents a differential diagnosis of pathological changes observed in the deciduous dentition of a child aged 3–4 years, recovered from a Late Roman (c. ad 270–410) cemetery at Ancaster, England. The entire maxillary dentition exhibited areas of missing enamel and erosion of the underlying dentine, which was most pronounced at the lingual surfaces of the anterior teeth, and lingual and occlusal surfaces of the molars. Additionally, the mandibular second molars and mandibular right first molar displayed superficial enamel erosion of the buccal surfaces. Radiography indicated normal enamel density, and no further dental pathology was identified. Conditions considered in a differential diagnosis included amelogenesis imperfecta, fluorosis, perimolysis, xerostomia‐related caries and early childhood caries (ECC). The nature and distribution of lesions implicates ECC – also known as ‘nursing caries’ or ‘baby‐bottle caries’ – as the most probable diagnosis. The potential significance of the findings for studies of infant health and feeding practices in past populations is discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

Minateda rock shelters (Albacete) and post-palaeolithic art of the Mediterranean Basin in Spain: pigments,surfaces and patinas

The inorganic and organic fractions of two microsamples of prehistoric paint from the same site, the Minateda rock shelters, are analysed here for the first time. The two samples correspond to two rock shelters of different styles (Levantine and schematic) – Abrigo Grande de Minateda (The Great Rock Shelter of Minateda) and Abrigo del Barranco de la Mortaja (Del Barranco de la Mortaja Rock Shelter). Since its discovery, historiographical tradition has emphasised the Abrigo Grande de Minateda, with its magnificence and complexity, as emblematic of the origin and evolution of rock art in the Mediterranean Basin of the Iberian Peninsula (a UNESCO World Heritage Site). Four complementary techniques –Microphotography, Scanning Electron Microscopy-Energy Dispersive X-Ray Spectroscopy (SEM-EDX), Raman Spectroscopy and Gas Chromatography–Mass Spectroscopy (GC–MS)– were combined to identify and characterise the physicochemical properties of the paint and of the surface. We present an interpretation of the results that leads us to define complex taphonomic alterations beyond the usual distinction of layers that include the surface, pigments and patinas.     

Calcium isotopes in archaeological bones and their relationship to dairy consumption

The calcium isotope ratios (δ^44/42Ca) of bones from humans and fauna from three archaeological sites, Taforalt, Abu Hureyra, and Danebury, are evaluated in order to assess whether calcium isotope ratios of bones can be used to detect dairy consumption by adult humans. At each site the fauna δ^44/42Ca is the same regardless of species, while the humans have lower δ^44/42Ca than the local animals by 0.24–0.41‰ (site means). However we cannot ascribe this difference to dairy consumption, given this human–faunal difference also occurs in Epipalaeolithic and Mesolithic adult humans, where dairy consumption is unlikely. Rather, this difference appears to be a result of differences in metabolic processes or other aspects of diet between humans and fauna. Minimal isotopic change in sequential acid leaches of bone powders and consideration of the high calcium concentration in bone suggest that bone calcium isotope ratios are not substantially affected by diagenetic change.     

Electrojet irregularity parameters from daytime equatorial scintillations

The second moment of the complex amplitude or the mutual coherence function (MCF) for transionospheric VHF radio waves transmitted from the geostationary satellite ATS-6 is computed from daytime amplitude and phase scintillations recorded at an equatorial station, in order to study the structure of electrojet irregularities. The shape of the correlation function for fluctuations in the integrated electron content along the signal path is deduced by using a theoretical relationship between this correlation function and the MCF which is based on the assumption that the irregularities are “frozen”. Further, using a power-law spectrum to describe the electrojet irregularities, the outerscale l_o associated with the spectrum as well as the r.m.s. density fluctuation are estimated from theoretical fits to the computed values. The irregularity drift speeds V_o transverse to the signal path, for the scintillation events studied here, are derived from power spectra of weak scintillations. On the basis of a relationship between l_o and V_o suggested by a linear theory of the gradient-drift instability, the effective Hall conductivity is estimated to be about five times the effective Pedersen conductivity in the electrojet region.     

The value of sieving of grave soil in the recovery of human remains: an experimental study of poorly preserved archaeological inhumations

The aim of this work is to assess the effects of sieving basal grave fills, following lifting of visible skeletal remains on the recovery of human bones and loose teeth in poorly preserved inhumation burials. The experiment was carried out during excavations at the 7th–9th century AD cemetery site at Whitby, England. Burials generally consisted of degraded bone fragments and/or soil stains. In each grave (N = 70 adult burials), all visible human remains were hand-collected on site; following this, the soil remaining in the grave was recovered and sieved successively through 8 mm, 4 mm and 2 mm meshes. No bone or dental fragments in the 2–4 mm fraction were identifiable to skeletal element. Approximately one third of the total weight of bone, and one third of the total numbers of teeth were recovered in the 4–8 mm and >8 mm sieved fractions. It is concluded that sieving down to 4 mm is adequate for recovery of adult skeletal remains at the study site. It would be useful to conduct similar sieving experiments at other archaeological cemetery sites to provide data on recovery when bone survival is good, and in subadult burials.     

Biofilm growth in human skeletal material from ancient Mesopotamia

Investigators have long recognised the effects of microbial activity on archaeological bone. These investigators, however, have focused on single or groups of microbes rather than on complex microbial aggregates such as biofilms, a focus that has affected our understanding of archaeological bone biodeterioration. In this paper, we report on the investigation of a biofilm in archaeological human bone from the site of Tell Leilan, Syria (2900–1900 BCE). Scanning electron microscopy indicated that the biofilm is characterised by single cells and microcolonies of bacteria and fungi, as well as calcite crystals that were all embedded within extracellular polymeric substances. Using culture techniques and DNA sequencing, we isolated and identified several microbes from the biofilm including Amycolatopsis sp., Penicillium chrysogenum, Aspergillus sp., Chaetomium sp., and Cladosporium sp. Having characterised the Leilan biofilm, we are now closer to understanding the complex process of bone biodeterioration in archaeological bone collections.     

Severe lead contamination among children of samurai families in Edo period Japan

This paper presents evidence for severe lead contamination among children of samurai families living in a castle town in Edo period Japan (1603–1867). Excavated rib bones were analyzed by atomic absorption, and soft X-ray roentgenograms of long bones were taken. The median values of lead concentration in the bones of children 3 years of age and under(1241.0 μg Pb/g dry bone) and 4–6 years of age (462.5 μg Pb/g dry bone) were significantly higher than those of adult males (14.3 μg Pb/g dry bone) and females (23.6 μg Pb/g dry bone) (p < 0.001). In addition, that of children over 6 years of age (313.0 μg Pb/g dry bone) was significantly higher than those of adult males (p < 0.01) and adult females (p < 0.05). The median value of lead in the bones of children 3 years of age and under was over fifty times higher than that of their mothers (adult females). Hypertrophy was seen in the long bones of five samurai children. In this area, lead lines or lead bands were distinguished by soft X-ray roentgenogram. Samurai children suffered from severe lead contamination in Edo period Japan. When the mothers were nursing their children, the children might have ingested their mother’s white lead non-selectively.     

Stable hydrogen isotopes of bone collagen in palaeodietary and palaeoenvironmental reconstruction

The stable hydrogen isotope ratios (δD) of bone collagen in archaeological human and animal samples demonstrate a trophic level effect, with increasing δD from herbivores to omnivores to humans, in steps of 10–30‰. In addition the archaeological sites studied (Yarnton, Eton Rowing Lake, Danebury Environs–Suddern Farm, and Windmill Hill in the UK, Balatonszárszó in Hungary, and Huari in Peru) demonstrate geographical variation in δD. The detection of manuring in prehistory by comparison of δ¹⁵N to δD values in humans and a local herbivore (cattle) is also considered. This work is the first to measure δD in a large number and range of archaeological samples, with several animal species and humans. It demonstrates unequivocally that δD is different between species in ancient material, increasing from herbivores to omnivores to carnivores.     

Ossified haematomas and infectious bone changes on the anterior tibia: histomorphological features as an aid for accurate diagnosis

Examination of the histological structure of bone not only helps investigators to estimate age at death but can also aid in the diagnosis of palaeopathological lesions. The purpose of this paper is to assess whether histological features as described in the literature can confirm the macroscopic diagnoses of ossified subperiosteal haematomas associated with healed scurvy and syphilitic bone changes observed on the anterior tibiae of individuals from a 19th century mining community from Kimberley South Africa. The frequent occurrence of these two diseases amongst the deceased was well established in related hospital documents and governmental documents. A section of bone was removed from lesions on the tibiae of 14 individuals. These bone changes were macroscopically diagnosed as being indicative of either treponematosis ossified subperiosteal haematomas or non‐specific periostitis. Cross‐sections were prepared for microscopic investigation using a manual ground section technique. Ossified haematomas were histologically identified in seven individuals. These sections were characterised by normal cortical bone an intact original periosteal surface and newly formed radiating trabecular bone apposing it. Three phases of ossified subperiosteal haematoma formation and remodelling could be distinguished. Infectious bone changes most likely associated with treponematosis were observed in one individual. These were characterised by lysis and numerous resorption holes/channels. No clear distinction could be made between the internal spongy cortical or newly formed bone. Histological features described by some authors as characteristic of this condition could not be identified. In addition three individuals presented with microscopic features indicative of both the aforementioned bone affections and three did not show any pathological changes on microscopic level. It was concluded that although specific pathological conditions can most likely not be diagnosed purely on the basis of histomorphological observations broad distinctions could be made between lesions caused by the ossification of subperiosteal haematomas and bone changes due to infectious diseases.

Post-medieval sheep (Ovis aries) metapodia from southern Britain

The ‘improvement’ of sheep (Ovis aries) in southern Britain during the post-medieval period is examined using measurements taken on the metacarpals and metatarsals from the late 18th to 19th centuries AD site of Tumbling Fields, Tiverton, Devon. This data set is a rare and important metric archive from which is derived information on the conformation (size and shape) of sheep. Comparisons are presented from other medieval and post-medieval sites, which demonstrate that Tumbling Fields is comparable to other sites of a similar period. The comparisons presented also reveal temporal variation with bones from later sites being taller and more robust on average than those from earlier sites. In addition, the abnormalities of sheep (O. aries) metapodia are examined. In particular, two different conditions are discussed: small, oval cavities in the proximal articulation of the metacarpals, and a ridge of bone on the proximal anterior shaft of the metatarsals. Comparisons are presented from other medieval and post-medieval sites, and potential aetiologies are discussed.     

Injuries on a skull from the Ancient Bronze Age (Ballabio,Lecco, Italy): a natural or an anthropic origin?

This paper discusses the results of the analysis of a female skull from a collective burial dated to the Ancient Bronze Age in Italy (Ballabio, LC). A virtual restoration and 3D reconstruction was also produced from the digitalized skull to complete the damaged parts and to recreate the facial appearance of this young adult female from the Bronze Age. The skull shows clear evidence of post-mortem modifications, as some series of scraping marks on the external cranial vault cross the parietal bones longitudinally. The contemporaneous presence of taphonomic linear marks on the skull and periostitis on the frontal bone, as well as the provenance of the specimen from a secondary burial (a typical funerary habit documented in Italy during the Copper Age and Ancient Bronze Age), makes it difficult to interpret the case (scalping, surgery, or ritual practice linked to secondary burial). The advanced methods used to analyse the skull surface allowed us to discriminate intentional marks from modifications due to other taphonomic processes and to determine the timing of their formation (peri- or post-mortem). The possibility that the scraping marks are related to a ritual practice, conducted during the individual's life (with specific symbolic or social value) or after death or at the moment of secondary burial, is discussed.     

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.     

Stable isotopes and diet at Ancient Kerma,Upper Nubia (Sudan)

Carbon and nitrogen stable isotope values were measured from bone collagen extracted from archaeological Nubian human (n = 54) and faunal (n = 61) populations from the site of Kerma, Sudan. Collagen suitable for isotopic analysis was extracted from 22 faunal and 48 human samples from the Eastern cemetery site, dated to the Middle Kerma (c. 2050–1750 BC) and Classic Kerma (c. 1750–1500 BC) periods respectively. The isotopic data indicate that the human dietary regimen included a mix of C₃ and C₄ plant-derived components, with a larger C₄ component than previously reported in archaeological Egyptian Nile Valley populations. Elevated δ¹⁵N values are attributed to consumption of dietary resources from a ¹⁵N-enriched terrestrial ecosystem. The faunal isotope data also indicate the consumption of C₃ and C₄ plants. The large range of δ¹³C values measured in both the human and faunal samples supports previous work suggesting that a significant portion of the populations buried at Kerma may have originated elsewhere, further confirming the Nile Valley as a major corridor for population movement in the region.     

Ancient-DNA reveals an Asian type of Mycobacterium leprae in medieval Scandinavia

Leprosy is a chronic infection of the skin and peripheral nerves caused by the pathogen Mycobacterium leprae. Its impact on human populations and societies of the past as well as its phylogeographic patterns around the world – at least in modern times – has been well documented. This slow growing bacterium has been shown to exist in distinct ‘SNP types’ that occur in relatively defined parts of the globe. The routes that the disease followed in the past are, however, still uncertain. This study of ancient-DNA typing of archaeological human remains from Sweden dated to early Medieval times provides genetic evidence that a transmission of M. leprae ‘SNP subtype’ 2G – found mainly in Asia – took or had already taken place at that time from the Middle East to Scandinavia. This finding is unique in the history of leprosy in Europe. All human specimens from this continent – both modern and ancient – that have been tested to date showed that the one responsible for the infection strains of M. leprae belong to ‘SNP type’ 3, whereas our results show that there were some European populations that were hosts to bacteria representing ‘SNP type’ 2 of the species as well.
