Skeletal metastatic carcinoma: A case from 15th–20th century Coimbra,Portugal

This paper discusses the differential diagnosis of unusual and distinct pathological changes in the skeletal remains of a 40+‐year‐old female from 15th–20th century Coimbra (Portugal). The most affected area seems to have been the skull, but multiple lesions, lytic and/or blastic, have been found throughout the post‐cranial skeleton, more specifically in the scapulae, clavicles, humerus, sternum, ribs, sacrum, innominates and femurs. The differential diagnosis of the lesions gave rise to several possible pathological conditions, namely, Langerhans cell histiocytosis (granulomatosis or Histiocytosis X), multiple myeloma and metastatic carcinoma. Various macroscopic and radiological aspects lead us to consider metastatic carcinoma as the most probable diagnosis. Despite the argumentative identity of the possible primary lesion, age, sex and the mixed nature of the osseous response are consistent with cancer of the breast but do not exclude other carcinomas, namely lung cancer. With temporal and regional differences emerging in the frequency of malignant tumours, the identification of new cases becomes important, particularly from geographic areas where few cases have been reported. In fact, the present report adds to the only case of metastatic carcinoma detected in non‐identified Portuguese human skeletal remains until now. Copyright © 2009 John Wiley & Sons, Ltd.     

The Sunghir 3 Upper Paleolithic Juvenile: Pathology versus Persistence in the Paleolithic

The Mid Upper Paleolithic Sunghir 3 late juvenile early modern human, from the most elaborate burial in the Pleistocene, had pathologically foreshortened and anteriorly bowed femora and, based on her dental enamel hypoplasias and transverse lines, sustained severe and persistent systemic stress throughout her decade of life. Her modest femoral and tibial asymmetry and her femoral bicondylar angles indicate non‐pathological patterns of posture and locomotion. The levels of rigidity for her weight‐bearing tibiae and the non‐dominant left arm reflect normal weight‐bearing and manipulation. These indicators are combined with an elevated level of right humeral strength, leading to pronounced humeral diaphyseal asymmetry, combined with elevated muscular insertion asymmetry. In combination with marked upper limb muscle markings and normal levels of bone formation, these reflections of her robustness indicate that she was fully mobile and participated actively in the tasks of her social group. There is no indication of the skeletal hypotrophy/atrophy that would be associated with less than full participation in the mobility and subsistence of her social group. As such, Sunghir 3 joins a growing list of developmentally or degeneratively pathological Late Pleistocene humans who nonetheless remained mobile and active.

Death in Flames: Human Remains from a Domestic House Fire from Early Iron Age,Denmark

This paper presents osteoarchaeological analyses of the human skeletal material from a burnt down house in Jutland, Denmark, dated to the first century bc . We describe how the osteological analyses of this complex site were approached and illustrate how we reconstructed the death of the human victims. Besides basic osteological analyses, we also tried to reconstruct the posture of the deceased humans using 12‐in. posable wooden mannequins. Along with bones from several domestic animals, skeletal elements from six human individuals were recovered. All individuals were located in the eastern end of the house—the byre end. The demographic structure indicates a small family household. Our posture reconstruction further proposes that they did not die of asphyxiation while sleeping: At least two of the individuals were lying face down, trying to protect themselves. Two other individuals were lying on their side in crouching positions, which cannot be ruled out as examples of pugilistic attitude. However, we suggest this is rather unlikely. The humans could have died as they failed to rescue their invaluable animals from the fire. Copyright © 2013 John Wiley & Sons, Ltd.     

Spotted hyena (Crocuta crocuta) den use and taphonomy in the Masai Mara National Reserve,Kenya

Hyena taphonomy is of great importance to studies of hominid evolution, since these carnivore taxa have the highest potential both to produce large osseous assemblages and to modify existing hominid-accumulated assemblages throughout the Old World. The three extant hyena species (brown: Parahyaena brunnea; striped: Hyaena hyaena; and spotted: Crocuta crocuta) are all significant bone collectors and modifiers. Spotted hyenas generally have the lowest potential to accumulate osseous remains, and the rate of accumulation varies based upon the type of den. The present research examines the remains accumulated by spotted hyenas in Masai Mara Cave, Masai Mara National Reserve, Kenya. The contents of this den were collected twice by the authors, with an 11-year span interceding. The taphonomic signatures of spotted hyena interaction with bone are presented, including species and skeletal element representation, breakage patterns, tooth marks, tooth puncture, edge polish, and gastric corrosion. Other taphonomic factors examined include rodent gnawing and weathering stage. The cave den assemblage was accumulated at a rate of 30.4 identified specimens and a minimum of 4.1 prey individuals per year. In addition, the osseous remains accumulated by spotted hyenas at multiple burrow dens within the Reserve were examined for taxonomic representation and multiple taphonomic parameters. Rates of accumulation at this type of den tend to be very low, due to differential usage by spotted hyenas and the more ephemeral nature of earthen dens.     

Severe vertebral collapse in a juvenile from the graveyard (13th/14th–19th centuries) of the São Miguel church (Castelo Branco,Portugal): differential palaeopathological diagnosis

Diseases that culminate into vertebral collapse are of intricate diagnosis both in palaeopathology and modern clinical practice. When analysing human skeletal remains from the archaeological record this difficulty is amplified due to the absence of complementary medical diagnostic information. This is especially evident when the distinction between tuberculous and pyogenic spondylitis is intended. Taking into consideration this challenging task and based on the macroscopic and radiological study of the skeleton number 8, a specimen exhumed from the East necropolis (13th/14th to 19th centuries) of the São Miguel church, at the Portuguese city of Castelo Branco, the aims of the work here presented are to discuss the range of possible aetiological factors, especially infectious ones, ascribable to the striking pathological changes noticed on this 12‐year‐old individual. These included alterations on the axial skeleton, namely extensive vertebral destruction, presenting as a gibbus deformity, and correlated thoracic deformities. Consubstantiated on palaeopathological and clinical research, tuberculous spondylitis seems to be the most probable cause for the reported lesions. However, the scrutiny between this condition and other pyogenic spinal infections is of extreme complexity when analysing ancient human remains and deserves in‐depth future investigations. Within the framework of the Portuguese archaeological record, the specimen here presented is of major relevance since the pattern and severity of the spinal osseous changes observed were not previously reported. Further, if tuberculous spondylitis is assumed as the most probable diagnosis, the case here presented represents one of the earliest skeletal evidence of this condition in Portugal.

Osseous talocalcaneal coalition in a medieval skeleton (ca. 1050 AD)

Tarsal coalition (TC) is defined as an abnormal fusion of two or more tarsal bones. The fusion may be fibrous, cartilaginous or osseous and can be congenital or acquired in response to infection, articular disorders, trauma, neoplasm or surgery. We report a case of a talocalcaneal (TCC) type of tarsal coalition in a medieval skeleton from Northwest Germany dating to ca. 1050 AD. The fusion is of osseous type. Plain AP radiographs and computed tomography confirmed the macroscopic diagnosis. Copyright © 2009 John Wiley & Sons, Ltd.     

An investigation of the frequency of squatting facets in Later Stone Age foragers from South Africa

Distinctive morphological changes attributed to a habitual squatting posture were observed on the distal femur, distal tibia and on the talar neck of Later Stone Age (LSA) foragers. The frequency of squatting in LSA foragers (n = 56) was determined by the presence of anatomical features of joint hyperflexion. Three South African comparative skeletal groups from different time periods were also analysed: skeletal remains of early farming populations (n = 17), 18th century ‘Free Blacks’ and/or slaves from Cobern Street, Cape Town (n = 21), and a modern cadaver sample (n = 29). The results show that 28 out of 56 LSA foragers (50%) were habitual squatters; 13 out of 17 farmers (76.5%) and one of 21 individuals from the Cobern Street collection (4.8%) demonstrated squatting facets. No anatomical squatters were found in the modern cadaver sample. There was no significant sex difference between squatters and non‐squatters. Hence at least half of the LSA foragers and farmers were habitual squatters, according to the signs of joint hyperflexion. Squatting is a comfortable position for those used to it because the body weight is supported with minimal muscular activity. Two probable reasons are suggested for the difference in postures adopted by the different groups: (1) availability or lack of availability of furniture and (2) cultural and individual differences in resting posture.

Hard core and cutting edge: experimental manufacture and use of Magdalenian composite projectile tips

The technology of the European Upper Palaeolithic yielded abundant evidence of the use of composite projectile heads, in the form of osseous points on the side of which one or several (micro)lithic elements are attached. Yet, little experimental work has been devoted to testing and assessing the parameters of use of this type of composite tips. In this paper we present a pilot experiment with replicas of Magdalenian composite spear tips, made of an antler point with one or two rows of flint backed bladelets. Two series of replicas were manufactured after the lithic and osseous record of, respectively, the Lower Magdalenian from southwest France (c. 20–18 Ky cal BP) and the Upper Magdalenian of Pincevent in the Paris Basin (c. 15–14 Ky cal BP). The 34 experimental composite heads were hafted to spears that were then shot with a spearthrower at the carcasses of two young deer. The results provide some insight into the performance characteristics of the osseous and lithic components, both in efficiency and durability. Finally, possible improvements of the experimental protocol are discussed, as well as the implications of our results for the understanding of projectile point variability in the Upper Palaeolithic.     

Benign mandibular tumours: Two case studies from the Maya lowland site of Tikal,Guatemala

This study presents a differential diagnosis of benign mandibular tumours identified in two adult burials from the precontact Maya city of Tikal, Guatemala. Both individuals were recovered from domestic structures that date to the Late Classic Period (AD 550–850). The osseous growths were interpreted as probable benign tumours based on evidence of localised growth, a circumscribed border, a dense texture and a lack of osteolytic activity or spiculate bone formation. Burial PTP‐026A is a middle adult (35–50 years) of indeterminate sex with evidence of a small dense, circular mass extending laterally from the right mandibular corpus. Macroscopic and radiographic assessment of this lesion provided a diagnosis of osteoma, a true neoplasm, or alternately, hyperplasia (e.g. exostosis) or hamartoma, which are not true neoplasms. Burial PTP‐017 is a probable young adult female (20–35 years) with a large osteoblastic lesion on the right anterior mandibular corpus. This dense, bony mass extends from the anterior margin of the mental canal, and shows a distinct boundary from the adjacent trabecular and cortical bone. The growth of the osseous mass displaced the right first premolar anteriorly. Radiographic assessment showed the presence of dense, radiopaque material, indicating significant calcification. This suggested a likely fibro‐osseous origin for this lesion, with a probable diagnosis of ossifying fibroma, or possibly osseous dysplasia. Although not definitive, our differential diagnosis was able to exclude a number of neoplastic and non‐neoplastic conditions that affect the jaws. This study provides the first reported cases of possible benign mandibular tumours in the ancient Maya. Copyright © 2009 John Wiley & Sons, Ltd.     

Big boats and bigger skimmers: determining Britain's role in the Long War

While much of the focus in the Trident replacement debate in the UK is on Britain's long-term role as a nuclear power, a second decision is imminent, concerning the acquisition of two large aircraft carriers. In combination, these two projects will do much to determine the UK defence posture for several decades to come and are therefore best analysed together. The decisions are particularly significant when viewed in relation to the post 9/II US defence posture, especially in what is now being termed the 'long war'. The new aircraft carriers will make it possible for the UK military to work closely with the United States in future expeditionary warfare, with all the potential political controversies that might result.     

Foot anomalies in the Late Neolithic/Chalcolithic population exhumed from the rock cut cave of São Paulo 2 (Almada,Portugal)

The study of developmental abnormalities of the tarsal bones in a Portuguese Late Neolithic population was performed, as part of an ongoing research project that includes the evaluation of foot defects in Portuguese skeletal populations from Neolithic times to modern 20th century samples. Two accessory bones were found, calcaneum secundarium and os trigonum, and three non‐osseous coalitions were detected, calcaneonavicular, cuboid‐navicular and third metatarsal‐third cuneiform. The newly presented frequencies corresponded to other published sources, except for the frequency of calcaneum secundarium, higher than in previous studies (8.6% left bones; 15.2% right bones). This result suggests population homogeneity maybe due to geographic isolation and/or marriage customs although the exact pattern of inheritance of the majority of these foot anomalies is unknown. No apparent sex bias was detected and side could not be tested since these human remains were uncovered from a commingled funerary context. Copyright © 2010 John Wiley & Sons, Ltd.     

A probable case of metastatic carcinoma from the late prehistoric eastern Tennessee River Valley

There are few described cases of metastatic carcinoma from the prehistoric eastern United States and none primarily differentially diagnosed from the southeast. A mature adult female exhibiting several large lytic cranial lesions suggestive of neoplastic disease was identified in a late prehistoric Mississippian Period (AD 1200–1600) context. Burial 371 is from Ledford Island, a Mouse Creek phase (AD 1400–1500) site from the Chickamauga Reservoir of southeastern Tennessee. It is the only case in this reservoir (total adult n = 843). The radiographs of the otherwise asymptomatic postcranium yielded radiolucencies in both proximal femora, both medial clavicles, the sternum, the surviving humeral metaphysis and fragmentary innominate. The locations are all consistent with metastasized carcinoma. The identity of the possible primary lesion is argumentative. Age, sex and the mixed nature of the osseous response are consistent with carcinoma of the breast but not to the exclusion of bronchogenic, thyroid, or kidney cancers.

Of stones and bones: Interpreting site function in the Upper Paleolithic and Mesolithic of Western Europe

Upper Paleolithic and Mesolithic excavations have usually yielded both artifacts and faunal remains in a variety of environmental settings across a latitudinal range from Belgium to Portugal. In some cases there seem to be functional relationships within levels between ungulate species and skeletal elements on the one hand and associated lithic and osseous artifacts on the other. In other cases—perhaps because of their nature as occupational and depositional palimpsests—the relationships are murkier. Examples examined here include La Riera and El Mirón caves (coastal and montane Cantabrian Spain, respectively), Dufaure rockshelter (Pyrenean lowland France), Magrite cave, Pape rockshelter, and Bois Laiterie cave and the Huccorgne open-air site (Ardennes upland, transitional zone, and central plateau of Belgium, respectively), and the Vidigal shell midden (coastal southern Portugal). The interpretation of site function (e.g., multi-purpose residential site, specialized logistical camp, or transit bivouac) is a matter of pragmatic, interdisciplinary, situation-specific analyses, and parsimony.     

A sixteenth‐century warrior grave from Uppsala,Sweden: the Battle of Good Friday

Little is known about the Battle of Good Friday in Uppsala. The historical records are scarce and of limited extent. Moreover, the more spectacular event of the Stockholm Bloodbath has drawn most of the attention from both the contemporary public and later historians. This is why the discovery of a mass grave in the steep slope of Uppsala Castle in 2001 has provoked much interest. An analysis of the osseous material showed that the remains of at least 60 male individuals, mostly between 25–34 years of age, were buried in the excavated area. The demographic profile is largely similar to other European war‐related skeletal assemblages of the same era. Sharp force trauma was exhibited primarily on the skulls, with no obvious dominance to either side. The trauma distribution pattern suggests that the battle was not fought face‐to‐face. Blade wounds concentrated in specific regions imply a standardised technique when delivering the blows. The combination of commingled bones and articulated elements suggests that the individuals were in different stages of skeletonisation when buried. Copyright © 2004 John Wiley & Sons, Ltd.     

Possible cases of scalping from pre‐hispanic highland Peru

For years, the pre‐Hispanic Chachapoya of Northern Peru have been described as the ‘Warriors of the Clouds’. A more detailed look at newly excavated osteological samples from the highland site of Kuelap allows us to better examine the types of traumatic injuries among the Chachapoya. This paper describes an individual with evidence of a recent scalp removal including cut marks encircling the vault and a large area of active inflammatory response due to exposure of the outer table. The degree of osseous response and a small area of healing indicate short‐term survival. A second fragmentary skull demonstrates similar features but more advanced healing. The location and patterning of the cut marks are consistent with North American Indian pre‐historic and historic cases of scalping. The skulls of these two individuals provide the first osteological evidence of scalp removal from a pre‐Hispanic South American Andean context, although it is difficult to determine the motivation whether for therapeutic treatment or trophy taking. These cases, along with other evidence of interpersonal violence and cranial trauma, serve to elucidate the possible volatile nature of cultural contact between this region and lowland Amazonian tribes, where scalps and trophy heads were commonly taken in raids.

Slipped proximal femoral epiphysis in a priest from the medieval period

During the course of a routine analysis of a cemetery burial population associated with the medieval hospital of St Giles, Brough, North Yorkshire, the partially excavated burial (No. 1423) of a priest, as identified through the associated chalice and paten dating to the medieval period, was observed to exhibit osseous changes commensurate with those of an untreated slipped proximal femoral epiphysis. Secondary osseous changes were noted that may indicate habitual positional behaviour subsequent to the injury.     

Comparison of fluoride and direct AMS radiocarbon dating of black bear bone from Lawson Cave,Missouri

Abstract

After a 20-year hiatus (1955–1975) during which few archaeologists discussed fluoride dating, the method again received attention in the 1980s and 1990s when some argued for its validity. As a dating method, fluoride dating depends on the rate at which fluorine ions replace hydroxyl ions in osseous tissue. The rate of replacement is influenced by the properties of the skeletal part (SP), sediment chemistry (K), and sediment hydrology (H), and the replacement rate influences estimates of time. Calibrated AMS radiocarbon assays of 10 black bear (Ursus americanus) femora from a natural-trap cave in central Missouri are weakly correlated with fluorine concentrations, determined by neutron activation analysis in the 10 femora. Despite minimal variation in SP, K, and H, results indicate fluoride dating can be considered a valid dating method only in cases when the chronological validity of its results are confirmed with independent chronometric data. As similarities in fluorine amounts across specimens increase, provenience information and bone orientation data as well as fine resolution data on K and H become critical to the application of fluoride dating.     

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.     

A case of valgus ankle in an early Pleistocene hominin

Bipedal locomotion is a defining character of the hominin lineage. A skeletal correlate of bipedality is a perpendicularly oriented tibia relative to the plane of the ankle joint, positioning the foot directly under the centre of mass. Non‐human primates, in contrast, possess a tibial shaft that tilts laterally away from the plane of the ankle joint (valgus ankle), which positions the foot in inversion and is adaptive for arboreal climbing. KNM‐ER 2596 is a small distal tibia from 1.9 mya sediments at Koobi Fora, Kenya. Though it possesses some morphologies functionally linked to bipedality, such as an expanded metaphysis, it also possesses a valgus tilt to the ankle. We test the competing hypotheses that the KNM‐ER 2596 tibia is from a cercopithecoid, a non‐human hominoid, or a pathological hominin. A survey of the orthopaedic literature and a comparative study of modern human and non‐human primate tibiae support the hypothesis that KNM‐ER 2596 is from a hominin. In order to investigate the non‐phylogenetic causes of valgus ankle, we examined human skeletal tibiae with valgus tilt secondary to fracture of the distal fibula. Untreated breaks of the lower third portion of the fibula during childhood can result in a valgus tilt to the distal tibia and occasionally other peculiar morphologies found in the KNM‐ER 2596 tibia such as a superoinferiorly atrophied medial malleolus. The morphology of this tibia is incompatible with hypotheses that it is from a cercopithecoid or a hominoid, and instead, we suggest that KNM‐ER 2596 belonged to a hominin that may have suffered a fracture of the lower left fibula as a juvenile.
