Cranial pathology of Ursus spelaeus ROSENMÜLLER & HEINROTH from Chateau Pignon,Basque Territories (Spain)

A complex lesion, on a skull of a female cave bear (Ursus spelaeus) associated with perforations of the frontal sinus is described. Paleopathological analysis suggests that the lesion is attributable to complex cranial trauma, probably complicated by an infection which appears to have occurred following a fight, most likely with another bear or, possibly, a cave lion (Panthera leo spelaea); at least one of the perforations observed on the skull may have been produced by the canine of a large carnivore. This hypothesis is supported by the frequent intraspecific aggressiveness documented in modern bears, and by evidence suggesting interspecific fights between cave bears and cave lions. The case is discussed in the light of other evidence reported in the literature. © 1998 John Wiley & Sons, Ltd.     

An interesting case of prehistoric trepanation from Poland: re‐evaluation of the skull from the Franki Suchodolskie site

The skull described here was excavated in Central Poland (archaeological site Franki Suchodolskie) in 1951, and was known as one of the oldest cases of healed trepanation. This skull, with later excavations from the Ukraine (cemeteries of Vasilyevka II and Vasilyevka III), was the basis for dating the beginning of the practice of trepanation in the Mesolithic period. The skull was never comprehensively described and dated, although it was scientifically extremely important. The skull has been reassessed by the authors of this paper has brought thorough verification of the knowledge concerning this excavation. According to radiocarbon analysis it is much younger than previously thought and has now been dated to the Late Neolithic or the Bronze Age. Earlier opinions about the healing and survival after the operation have not been confirmed: the hole in the squama of the frontal bone made by scraping and then by grooving has no evidence of healing. Radiological studies as well as computer tomography indicate lack of any healing processes in the bone tissue around the trepanation opening. The results of the analysis significantly modify ideas regarding the earliest skull operations in Central Europe, and change the time of the first trepanation to the Late Neolithic, as for most of the continent.

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.     

An unusual cluster of meningiomas?

Three cases of meningioma are described from a single site in Hertfordshire yielding a total of 83 male and 84 female burials. The lesions were present in the parietal and frontal bones, and were bilateral in one case. All presented as a defect in the inner table of the skull and were supplied by a large aberrant artery; in two instances the lesion had eroded completely through the skull but no hyperostosis was present. The unusually high prevalence of this tumour is discussed in the light of other palaeopathological findings. © 1998 John Wiley & Sons, Ltd.     

Neurosurgical aspects of trepanations from Neolithic times

Trepanation of the cranial vault is the oldest known surgical procedure and has often been reported in the literature. We present two skulls with trepanations from Neolithic excavations in southwestern Germany. One skull exhibits a healed fracture in association with the trepanation. Both skulls show clear signs of healing without evidence of osteolytic inflammatory reaction. We discuss conditions relating to survival from trepanation in Neolithic times and some potential complications such as intraoperative bleeding and wound infection, in the context of modern neurosurgical knowledge. We conclude that neolithic skull surgery was probably mainly extradural. Copyright © 2006 John Wiley & Sons, Ltd.     

A possible fatal wounding in the prehistoric Pacific Islands

This paper reports two cases of prehistoric interpersonal violence from Taumako Island, southeast Solomon Islands. The first case is a young child with a bone point found in situ in a lower lumbar vertebra. It is concluded that this child most likely died as the result of the injury. The second case is a male of advanced age with a well‐remodelled depression fracture on the frontal bone of the skull. This individual also has a remodelled penetrating wound to the left iliac crest of the pelvis. Warfare is thought to have been endemic in much of the Solomon Islands before European arrival. However, besides the two cases reported here there is little other evidence of trauma in the Taumako population. The young child is the first case of an in situ weapon reported from the prehistoric Pacific Islands. Copyright © 2000 John Wiley & Sons, Ltd.     

Two decapitations from Roman Towcester

Two young adult males from a Roman cemetery at Towcester show unambiguous evidence of decapitation In one, the skull had been placed over the lower legs, and in the other, the skull was in its correct anatomical position. The significance of this variation and the reasons for decapitation are discussed. Copyright © 2001 John Wiley & Sons, Ltd.     

The origins of two purportedly pre-Columbian Mexican crystal skulls

The well-known life-size rock crystal skull in the British Museum was purchased in 1897 as an example of genuine pre-Columbian workmanship, but its authenticity has been the subject of increasing speculation since the 1930s. This paper is concerned with the history, technology and material of the skull and another larger white quartz skull, donated recently to the Smithsonian Institution. Manufacturing techniques were investigated, using scanning electron microscopy to examine tool marks on the artefacts, and compared with Mesoamerican material from secure contexts. A Mixtec rock crystal goblet and a group of Aztec/Mixtec rock crystal beads show no evidence of lapidary wheels. They were probably worked with stone and wood tools charged with abrasives, some of which may have been as hard as corundum. Textual evidence for Mexican lapidary techniques during the early colonial period, supported by limited archaeological evidence, also indicates a technology without the wheel, probably based on natural tool materials. In contrast, the two skulls under consideration were carved with rotary wheels. The British Museum skull was worked with hard abrasives such as corundum or diamond, whereas X-ray diffraction revealed traces of carborundum (SiC), a hard modern synthetic abrasive, on the Smithsonian skull. Investigation of fluid and solid inclusions in the quartz of the British Museum skull, using microscopy and Raman spectroscopy, shows that the material formed in a mesothermal metamorphic environment equivalent to greenschist facies. This suggests that the quartz was obtained from Brazil or Madagascar, areas far outside pre-Columbian trade networks. Recent archival research revealed that the British Museum skull was rejected as a modern artefact by the Museo Nacional de Mexico in 1885, when offered for sale by the collector and dealer, Eugène Boban. These findings led to the conclusion that the British Museum skull was worked in Europe during the nineteenth century. The Smithsonian Institution skull was probably manufactured shortly before it was bought in Mexico City in 1960; large blocks of white quartz would have been available from deposits in Mexico and the USA.     

Trauma to the Skull: A Historical Perspective from the Southern Levant (4300BCE–1917CE)

Background: Although the southern Levant is commonly perceived as having been a violent region throughout history, few studies have explored the pattern and intensity of skull trauma through time in the general population. The aim of this study is to follow changes in traumatic injury patterns in the southern Levant, over an extensive period of 6,000 years. Methods: 783 archaeological skulls from the Tel Aviv University osteological collection were examined for evidence of trauma. The specimens were divided into three periods: Chalcolithic‐Bronze‐Iron Age (4300–520 BCE), Hellenistic‐Roman‐Byzantine Period (332 BCE‐640 CE), and Early and Late Arab Period (640–1917 CE). The characteristics of injury on each skull were recorded. Results: A high frequency (25%) of traumatic lesions to the skull was evident among historic populations of the southern Levant, a rate that did not fluctuate significantly over 6,000 years. The most common pattern of trauma was minor circular depressed injuries. Most of the injuries were located on the parietal or frontal bones. Traumatic lesions were more frequent in males than in females, and in mature individuals than in adolescents and children, during all periods. Conclusions: The rate of trauma in the southern Levantine populations was shown to be considerably higher than in other archaeological populations worldwide. The fact that no significant differences in trauma rates were found over time implies that socio‐economical shifts (from agrarian to urban populations) had little impact on the local populations’ aggressive behavior. In contrast, changes in type of injury, from blunt force trauma to sharp force trauma and eventually projectile trauma, reflects changes in weaponry over time. The accumulated characteristics of cranial trauma pattern (type, location, side, size, sex, age) suggest that most of the individuals studied were not engaged directly in warfare. Rather, most injuries seem to be due to blows given during interpersonal violent encounters. Copyright © 2012 John Wiley & Sons, Ltd.     

Evidence of interpersonal violence at the Chalcolithic village of Shiqmim (Israel)

Three circumscribed depressed fractures were found on the skull of an adolescent boy recovered from a primary intramural burial at the Chalcolithic site of Shiqmim, northern Negev, Israel dated to (∼4500–3200 BCE). The fractures were located on the left side and back of the skull. They are circular in outline and have sharp margins containing numerous small bone fragments. These indicate that the skull was fractured when the bone was still fresh and were the probable cause of death. The location of the fractured areas is typical of blows inflicted by a right‐handed individual in face‐to‐face conflict. The size and shape of the fractures, suggests that they were inflicted by a blunt instrument, possibly a mace head. The absence of any signs of healing or infection indicates that all fractures occurred within a short space of time and resulted in death. Neither biological characteristics nor burial pattern show any unique features that distinguish this individual from others recovered at this site. Copyright © 2003 John Wiley & Sons, Ltd.     

Neolithic dogs: A reappraisal based on evidence from the remains of a large canid deposited in a ritual feature

A canid skull and mandible, dated to the late neolithic, produced a series of measurements which indicate an animal significantly larger than any dog recovered from this period. The skull showed evidence of healed trauma with associated asymmetry. Metrical and morphological criteria have been applied to identify the remains as those of wolf Canis lupus, and the results of these tests are inconclusive. The possibility that the remains are of a large dog, Canis familiaris, is discussed, together with the implications that this may have for the archaeological consideration of this species.     

Effects of artificial deformation on cranial morphogenesis in the south central Andes

One of the most interesting issues of the interface between biology and culture is the artificial deformation of the skull. This modification is produced during early morphogenesis through the use of devices that alter the normal growth and development, to obtain a culturally established model. This paper, using a large cranial sample from the South Central Andes (1586 individuals), describes and documents a detailed morphometric study of the changes affecting the vault, cranial base, face, orbits and nasal region resulting from the tabular erect (TE), tabular oblique (TO), circular erect (CE) and circular oblique (CO) deformations with respect to the model without deformation. Data from 17 metric variables were processed by a one‐way ANOVA and LSD test for paired comparisons. All of the deformation types produce significant morphometric divergence in most of the anatomical structures of the skull. The TE exhibits: a restriction of antero‐posterior growth producing expansion in cranial width and height, frontal flattening, shortening of the face and cranial base, widening of the face, increased nasal and orbit height (ORH) and a foramen magnum size increase. The TO exhibits: most change reflected in the widening of the cranial vault, shortening of the cranial base and face, frontal flattening, increased nasal and ORH and foramen magnum size decrease. The CE style exhibits: a decrease in cranial width and strong increase in the cranial height, a reduction in frontal width, expansion of the cranial base and face, increased nasal and ORH, orbital widening and a foramen magnum size increase. The CO style exhibits: a decrease of the cranial vault's width and height, expansion along its length, stretching of the cranial base and face, reduced frontal width, fronto‐malar and biorbitary elongation of the face and further development of foramen magnum.

Multiple Calvarial Lytic Lesions: A Differential Diagnosis from Early Medieval France (5th to 7th c. AD)

A skull from the early French Medieval period presenting multiple destructive lesions is investigated. The study of this presumably young female skull suggests a series of possible diagnoses using macroscopic features, standard radiography, CT, and 3D analysis. After a review of the paleopathological and medical literature, the debate focuses on several malignant disorders (cancerous metastases, multiple myeloma), Langerhans cell histiocytosis, and other benign conditions such as infection (especially tuberculosis) or sarcoidosis. Although the definite diagnosis of such paleopathological lesions is not straightforward, Langerhans cell histiocytosis is the most probable diagnosis. Copyright © 2012 John Wiley & Sons, Ltd.     

The use of large numbers of variables to measure the shape of a restricted area of bone

A series of 28 “depth” measurements, from a fixed plane to a bone surface (the frontal bone of the human skull), is presumed to contain information about shape. Data are presented for three groups of skulls and a few problematic single ones. A simple method for reducing the 28 measurements to a few shape contrasts is described. Reasons why the data are unsuitable for a canonical analysis are discussed and possible problems arising from the uncritical use of canonical analysis in general are pointed out. Some general comments are made as to the relative morphological affinities of the comparative groups selected, and especially the single more controversial specimens.     

The Ciempozuelos Necropolis skull: a case of double trepanation?

The focus of this study is the analysis of a trepanation performed on the skull of an adult male from the famous Bell Beaker necropolis of Ciempozuelos (Madrid) excavated at the end of the 19^th century. The unusual characteristics of the pottery and other associated grave goods gave rise to the use of the name ‘Ciempozuelos’ to define the regional Bell Beaker style; this refers to similar finds from other sites on the Meseta of central Spain. Although trepanations from Chalcolithic contexts in the Iberian peninsula are not infrequent, they are unusual in Bell Beaker inhumations. Furthermore, this skull is exceptional not only for the type of trepanation performed, but also for the subsequent cranial deformation apparently resulting from the operation, as well as evidence of a second subsequent trepanation which indicates a very short post‐surgical survival period for the individual.

Shape Change and Variation in the Cranial Morphology of Wild Canids (Canis lupus,Canis latrans,Canis rufus) Compared to Domestic Dogs (Canis familiaris) Using Geometric Morphometrics

Wild canid populations exhibit different anatomical morphologies compared to domesticated dogs in North America. This is particularly important concerning archaeological sites, which may contain early domesticated species, for the proper identification of osteological remains. Previous studies have indicated domestic dogs exhibit a shorter rostrum accompanied by a crowded tooth row; however, none describe the overall complexity of these changes. Consequently, using a landmark‐based geometric morphometric analysis, cranial morphological characteristics were examined in North American wild canids: the gray wolf (Canis lupus), coyote (Canis latrans), red wolf (Canis rufus), and the domestic dog (Canis familiaris). The shape and size of the cranium in lateral and ventral views were compared between the three wild species to the group of domesticated dogs. Wild canids clustered separately from the domestic group in all statistical analyses. Results indicate an expansion of the orbital region, a compression of the rostrum, and an overall warping in the shape and orientation of the skull. In domestic species, there is also a downward shift in the frontal portion of the skull accompanied by the braincase assuming a more upward position. This technique successfully depicted how slight changes in isolated areas of the cranium can have an impact on the overall shape and morphology of the skull. We presume these changes in cranial anatomy reflect the recent selective pressures domestic dogs have undergone since diverging from their wild ancestors.

On sinking Otavalo man

The human remains from the Otavalo site, Ecuador, are claimed to be of Upper Pleistocene date, but there are reasons to doubt this. Morphological details, radiocarbon evidence and other aspects are considered together. It is suggested that the time has come to remove the skull firmly from the fossil record.     

Tropospheric gravity waves and their possible association with medium-scale travelling ionospheric disturbances

Analysis of pressure fluctuations observed over a period of several days using an array of microbarographs has shown the existence of long trains of gravity waves with two or more waves often present simultaneously. Meteorological data from radiosonde ascents indicates that many of the waves have a velocity which matches that of the background wind at some level within the troposphere. Generally this height corresponds to that of a frontal zone marking the transition between air masses and it is suggested that the waves may have been generated by shear flow instability within the frontal layer. Theoretical considerations, based on a three-layer model troposphere, show that some of the observed waves could have been ducted in or near the frontal zone. Some evidence is found to indicate that a non-linear wave-wave interaction between pairs of waves occurring simultaneously in the frontal zone could yield secondary waves with the characteristics of the gravity waves which had been observed in the thermosphere at appropriate times and whose group paths were traced to source regions in the troposphere in the general vicinity of the microbarograph array.     

Early Human Decapitation, 11,700–10,700 cal bp,within the Pre‐Pottery Neolithic Village of Tell Qaramel,North Syria

The process and timing of skull removal remains poorly understood by researchers. New archaeological and skeletal analysis from two skeletons from the early Pre‐Pottery Neolithic site of Tell Qaramel, northern Syria, highlights that Neolithic villagers used stone tools to physically decapitate the dead. Drawing upon cutmarks on the axis and the mandible from primary and secondary burials, we employed a scanning electron microscope to document how Neolithic people cut the ligament and its surrounding connecting tissues that bind the cranium with the bones of the axis and the mandible. The position of the cutmarks, especially at the top of the odontoid process of the axis, illustrates the complexities of intentional skull removal. From these and associated burial data, we illustrate that Levantine Neolithic people had specific practical codes for the sequence of skull removal, but given variation in the decomposition of the human body, at times, villagers had to use flint tools for skull removal. This study provides evidence of some of the world's earliest examples of intentional decapitation within human communities. Copyright © 2013 John Wiley & Sons, Ltd.     

Legalized trauma

In the past, criminals were executed by a variety of means, including beheading or hanging, and both these methods may leave signs on the skeleton. It is not difficult to recognize individuals who have been beheaded because one or other of the cervical vertebrae will show evidence of the fatal blow, and there may also be cut marks on the base of the skull or the back of the mandible. Death from hanging, however, often leaves no marks on the skeleton, especially when carried out with a running noose and no drop. With a drop, dislocation of the sutures at the base of the skull may be noted and the classic ‘hangman's fracture’, which is a fracture dislocation of the second cervical vertebra, may be present. When there is no evidence of trauma, death from hanging may have to be inferred in skeletons which are found with the hands tied or with other signs that are discussed here.
