Rib fractures in the archaeological record: a useful source of sociocultural information?

Investigation of palaeopathological fractures has been shown to provide important information on past societies. However, despite the fact that rib fractures are amongst the most commonly recorded types of fractures in archaeological bone, little attention has been paid to them. Although there will be sites with badly preserved ribs, making their study difficult, this will not always be the case. Recent clinical investigations have highlighted the potential significance of rib fractures with regard to morbidity and mortality, and their importance in relation to health is now appreciated. This study investigates rib fractures in 352 adults from St. Martin's churchyard, Birmingham, England. The crude prevalence of rib fractures was found to be 15.6% and the true prevalence rate 2.3%. The majority of the fractures occurred in males, and those buried in vaults were less likely to have a fracture than individuals from earth‐cut graves. In 11 individuals the fractures were healing at the time of death, and in these cases death was probably related to one of the complications that are frequently linked to fractured ribs. Certain types of accidents may have been linked to these more serious fractures, as 70% occurred in the same anatomical area. Other rib fractures were associated with pathological conditions, such as osteomalacia and osteoporosis. Overall, the study of the rib fractures in this collection provided valuable information that aided interpretation of the lifeways of individuals investigated. It is argued that where preservation permits, studies of fractures in archaeological bone should include ribs. Copyright © 2005 John Wiley & Sons, Ltd.     

A new plant from the earliest Carboniferous of Jiangsu,China

A new plant, Multifurcatus tenellus gen. et sp. nov., is described from the earliest Carboniferous of Jiangsu, China. The branching pattern is predominantly trifurcate with a main axis and paired subordinate branches. There are three orders of lateral branches. Two appendages are inserted at nodes, each dichotomized up to five times. Three appendages or fertile units at nodes are borne on the IV^th order branch. The fertile unit at the nodes of the IV^th order branch is made up of one sporangium and an appendage.     

A temporal bone lesion in a modern subject to explain a defect in the Kabwe skull

The skull of a dissection room subject was noted to have a hole in the left squamous temporal bone similar to a lesion in the Kabwe (Broken Hill) skull. Kabwe man has an 8 × 8 mm hole situated 2 cm above and slightly anterior to the left external auditory meatus (EAM). This report describes a possible mechanism for the causation of that lesion, which is illustrated by features on a modern skull. The subject is a 55-year-old man who died from carcinoma of the stomach in 1942. The skull was macerated, defatted and stored after the cadaver had been dissected by medical students. In the squamous temporal bone there was an oval shaped 9 × 8 mm hole. The base of the oval was situated 11 mm above the superior margin of the EAM with the central axis of the hole being in line with the anterior margin of the EAM. This hole forms the base of a larger intracranial pit measuring 21 mm in diameter. The hole has an irregular margin except superiorly where it is smooth and rounded, indicative of healing. Intracranially, the petrous temporal bone displayed a marked exophytic, bony outgrowth suggestive of a chronic infective condition. The tegmen tympani contained a hole 3 mm in diameter in the middle of the exophytic area. No sign of disease in the mastoid process was noted. These findings are compatible with advanced chronic ear disease which has tracked into the extradural space through the tegmen tympani, become loculated, and then eroded the squamous temporal bone. The Kabwe skull shows signs compatible with chronic ear disease. It is suggested that a mechanism similar to the one described in the modern skull could explain the lesion in the left squamous temporal bone of Kabwe man.     

Septic bone changes in leprosy: A clinical,radiological and palaeopathological review

Infective lesions of bone in leprosy are of two types. In the rhinomaxillary syndrome, superficial infective changes in the bones of the maxilla are due to the presence of Mycobacterium leprae. Lytic foci in the medulla or the outer cortical surface may be due to Mycobacterium leprae at the site as granulomatous lesions. The most frequent infective bone changes in leprosy are, however, sequelae of regional anaesthesia and soft tissue ulceration. The bone lesions are due to pyogenic bacteria and the nature of these infective lesions is similar to that in non-leprous conditions. The pyogenic lesions in leprosy are restricted to the bones of the hands, feet and lower legs.     

Stapedial footplate fixation in a 4000-year-old temporal bone from Franzhausen II,Austria

In one of 185 temporal bones from 100 individuals excavated from the Bronze Age cemetery Franzhausen II in Lower Austria, stapedial footplate fixation was detected, in a 16–20-year-old male. Examination by surgical microscope, flexible endoscope and computed tomography revealed that the stapes footplate is almost completely fixed into the oval window, with abnormal bone formation in its anterior end. As shown by computed tomographic imaging there were no radiolucent zones around the cochlea, which can sometimes be seen in modern patients with cochlear otosclerosis. Most findings lead to the conclusion that this case of a stapes ankylosis nearly 4000 years ago is probably due to otosclerosis.     

The distribution of osteoarthritis of the hands in a skeletal population

The distribution of osteoarthritis of the hands was studied in 101 skeletons from archaeological sites in England. The results are similar to those found in epidemiological studies of modern populations. Osteoarthritis of the hands was more common in females than in males, and in females tended to involve a greater number of joints. The distal and proximal interphalangeal joints were commonly affected, the former more frequently than the latter, but otherwise the disease was largely confined to the first ray of the hand, centred on the trapezium. It is concluded that the pattern of osteoarthritis in the hand has probably not changed greatly over several hundred years.     

The rhinomaxillary syndrome in leprosy: A clinical,radiological and palaeopathological study

The rhinomaxillary syndrome consists of a group of maxillary bone changes, which may be present in part or in total, in lepromatous and near-lepromatous leprosy. The changes are a composite mixture of erosive, absorptive and proliferative bone reactions. The anatomical zones involved are the alveolar process of the maxilla, the anterior nasal spine, the palatine process of the maxilla, intranasal osseous structures, and the margins of the nasal aperture.     

Staining ground sections of natural dry bone tissue for microscopy

The histological staining of bone tissue is of great value in identifying structural changes in human bone tissue when examined microscopically, and is therefore routinely used by clinical pathologists. However, for archaeological and other types of undecalcified dry bone tissue, histochemical staining is currently not widely used. The purpose of this paper is to describe a new method developed for the staining of undecalcified archaeological bone which may be a valuable addition to the palaeopathological toolkit. Sections were ground by hand and stained with haematoxylin and eosin. The microstructure and architecture of the stained sections become clearly visible without compromising total tissue envisioning. In addition, staining enhances differentiation between taphonomically affected and non‐affected bone tissue. This paper accordingly describes a reproducible stepwise method for the production of ground stained sections. An additional troubleshooting paragraph discusses the most often encountered problems and provides solutions. Copyright © 2010 John Wiley & Sons, Ltd.     

The EB IA tombs and burials of Bâb edh‐Dhrâ, Jordan: a bioarchaeological perspective on the people

The transition from a hunting/gathering economy to an agricultural economy, beginning about 10,000 years ago, was accompanied by the development of specialised innovations including nomadic pastoralism. It was also associated with the emergence of increasingly sedentary human societies in which relatively large numbers of people lived in a crowded urban environment. The dynamic relationship between agriculture and urbanisation undoubtedly had a profound effect on evolutionary dynamics in developing complex human societies. By the beginning of the Early Bronze Age (EB IA, ca. 3300 BCE) an agricultural economy was well established in the region surrounding Bâb edh‐Dhrâ, located in the southeastern plain adjacent to the Dead Sea in Jordan. However, the site apparently did not begin to develop as an urban centre until EB IB. The objective of this paper is to explore what is known about the EB IA people of Bâb edh‐Dhrâ. The presence of infectious and metabolic diseases coupled with high infant mortality and low life‐expectancy at birth suggest a society at risk. Nevertheless the people were robust and give evidence of at least a moderately successful adaptation to the environment in which they lived. Published in 2007 by John Wiley & Sons, Ltd.     

Stable–unstable flow of geothermal fluids in fractured rock

Density-driven geothermal flow in 3-D fractured rock is investigated and compared with density-driven haline flow. For typical matrix and fracture hydraulic conductivities, haline flow tends to be unstable (convecting) while geothermal flow is stable (non-convecting). Thermal diffusivity is generally three orders of magnitude larger than haline diffusivity and, as a result, large heat conduction diminishes growth of geothermal instabilities while low mass diffusion enables formation of unstable haline 'fingering' within fractures. A series of thermal flow simulations is presented to identify stable and unstable conditions for a wide range of hydraulic conductivities for matrix and fractures. The classic Rayleigh stability criterion can be applied to classify these simulations when fracture aperture is very small. However, the Rayleigh criterion is not applicable when the porous matrix hydraulic conductivity is very small, because stabilizing fracture–matrix heat conduction is independent of matrix hydraulic conductivity. In that case, the numerically estimated critical fracture conductivity is nine orders of magnitude larger than the theoretically calculated critical fracture conductivity based on Rayleigh theory. The numerical stability analysis presented here may be used as a guideline to predict if a geothermal system in 3-D fractured rock is stable or unstable.     

Well preserved non‐collagenous extracellular matrix proteins in ancient human bone and teeth

Ancient bones in a good preservation state, ascertained by microscopic techniques, conserve extracellular matrix proteins over thousands of years. With new techniques, intact extracellular matrix proteins from ancient bones and teeth are extracted and separated by one‐dimensional and two‐dimensional electrophoresis. Proteins were identified in Western blots by special antibodies against different human extracellular matrix (ECM) molecules of bone. We have confirmed different types of ECM human bone molecules such as osteonectin, osteopontin, and alkaline phosphatase with specific antibodies in human bone samples from different age groups. Additionally, we selected bone samples from different cultural time periods, such as the Middle Ages, the Bronze Age and the Late Pre‐Pottery Neolithic Phase (PPNB), and teeth from individuals from the Early Middle Ages and from the Late PPNB. The survival of intact extracellular matrix proteins in ancient bones and teeth dating from recent times to the Late PPNB, and reliable techniques to identify these proteins, present a great challenge to further research. A Match Set with PD‐Quest 7.2 shows that only 16% of protein spots in the teeth are also found in the bone of the same individual. In combination with the results of macro‐ and microscopic investigation, biochemical techniques will help us in obtaining a better understanding of bone and teeth in health and disease.

The Chalcolithic burial cave in Ma'avarot,Israel, and its palaeoanthropological implications

This paper reports on bioarchaeological and palaeopathological investigations of the Chalcolithic Ma'avarot burial cave in the Hefer valley (Sharon central coastal plain), Israel. The objective of this project was to retrieve enough data from the anthropological material which, in conjunction with the rest of the archaeological record, would help to better elucidate aspects of the archaeological questions concerning the Chalcolithic in the Levant. The integrated analysis of the archaeological record included studies of burial customs and practices, the associated material culture, skeletal biology, pathology and bone archaeometry. Correlations are made with the current and contradictory arguments about the migration of peoples and cultural diffusion and the explanatory hypothesis supporting autochthonous cultural developmental processes at this chronological juncture in the Levant. © 1998 John Wiley & Sons, Ltd.     

The earliest cylinder seal in the Arabian Peninsula

A cylinder seal of Late Uruk (late fourth millennium BC) type from Abu Dhabi is presented and analysed. Comparisons with excavated finds from elsewhere in the Near East are discussed. An inventory of cylinder seals from sites in the UAE and the Sultanate of Oman shows that cylinder seal use, while not unknown in the region, was never very great. The ways in which the seal may have arrived at its eventual place of discovery are described and the significance of the seal is assessed.

‘The bullets buzzed like bees’: Gunshot wounds in skeletons from the Battle of the Little Bighorn

Gunshot trauma is an important, but often overlooked, avenue for interpreting the historic past. Ten skeletons of Seventh Cavalry troopers, killed during the Battle of the Little Bighorn in 1876, are analysed osteologically. Six of the ten specimens have gunshot wounds, including three to the cranial vault. The other wounds are to postcranial remains, including one in an innominate. This wound location aids the identification of the individual, confirming and complementing historic accounts. Of the remaining two, one is to the humerus and the other to the chest region. These wounds provide insights into the nature of perimortem injuries, weapons used in the battle, and interpretations of the battle.     

The ‘caries correction factor’: A new method of calibrating dental caries rates to compensate for antemortem loss of teeth

Dental caries rates are frequently based exclusively upon the number of carious teeth observed in a human skeletal series. However, a portion of the teeth lost antemortem will be lost because of severe carious decay, a factor not considered by many investigators. This paper reviews and critiques earlier attempts to adjust dental caries rates to account for antemortem loss of teeth, and proposes a new ‘caries correction factor’ that is population specific, requires no assumptions, and is sensitive to the temporal and ecogeographical context of a skeletal series. An example of how to apply this caries correction factor is provided using new data from the Bronze Age site of Harappa in northern Pakistan. Its value in dental palaeopathology is reviewed with two recent studies of dental caries in the Arabian Gulf, and concludes with a consideration of its possible application to non-human primates.     

Scapular stress fracture: a palaeopathological case consistent with crutch use

This report describes a defect on the right scapula of a 50 to 60 year old male slave who had been buried extra‐muros in the Le Colombier cemetery of Vaison‐la‐Romaine (5^th to 6^th century AD) in Vaucluse, France. This injury can only be described as a stress fracture, most likely associated with heavy and persistent use of the humerus in abduction. Other bony defects on the skeleton included early signs of ossification of the glenohumeral joint, slight vertebral discopathy, and osteoarthrosis on the right hip. A relationship between scapular stress fractures and walking devices has been described in the current medical literature, and taking this in consideration, possible aetiologies for this scapular defect include either consistent use of a crutch or routine physical labour. Little information is available on either stress fractures or assisted walking devices in antiquity; therefore this information is a valuable contribution to palaeopathology.

Clay‐shoveler's fracture: an uncommon diagnosis in palaeopathology

An archaeological case of clay‐shoveler's fracture was observed in an adult male exhumed from a Roman necropolis dated to the 1st–3rd century AD and located in the city of Barcelona, Spain. Clay‐shoveler's fracture is a breakage of a lower cervical or upper thoracic spinous process as a result of mechanical stress. Different mechanisms have been related to this injury, generally in labour‐related contexts. This paper reviews the literature concerning this uncommon finding, focusing especially on its mechanism and on activity‐related lesions. Copyright © 2006 John Wiley & Sons, Ltd.
