Intercemetery morphological variation in Arikara crania from the Mobridge Site (39WW1).
Multivariate analysis is used to examine intrasite variation in cranial morphology in the Mobridge Arikara skeletal collection. The site included three spatially distinct burial areas. The burial areas (features) are defined according to geographic location. Feature 1 is a small hill west of the village. Feature 2 is a large, long hill 200-300 yards south of the village. Feature 3 is a small knoll 100 yards south of Feature 1. The internal chronology of Mobridge has not been established with precision, but order has been postulated based on archeological data. Previous researchers have considered area 2 to be later than areas 1 and 3. Significant morphological heterogeneity exists between areas. Sample differences indicate that specific features were used by temporally distinct populations. The archaeologically proposed temporal ordering of the cemeteries is supported by osteological evidence.

Age and sex biases in the preservation of human skeletal remains.
Inaccuracies introduced through biases in preservation are a major source of error in paleodemographic reconstructions. Although it is generally assumed that such biases exist, little is known about their magnitude. To investigate this problem, we studied age and sex differences in the preservation of skeletal remains from Mission La Purisima and a prehistoric cemetery (Ca-Ven-110). Comparison of mortality profiles obtained through analysis of skeletal remains and burial records from the mission indicates that biases in preservation can be very significant in poorly preserved skeletal collections. The Purisima burial records show that most of the people interred in the cemetery were either infants or elderly adults. The skeletal remains, in contrast, are predominantly those of young adults. The burial records and skeletal collection produced comparable sex ratios. These results show that age biases in preservation are much more important than sex biases. This conclusion is supported by data on the completeness of the skeletons from La Purisima and Ca-Ven-110. At both sites, the remains of young adults were better preserved than those of children or elderly adults, and the completeness of male and female skeletons was comparable.

Analysis of dental attrition and mortality in the Medieval village of Tirup, Denmark.
New directions and new questions raised in the study of health in the past justify this reanalysis of the pattern of dental attrition in the Medieval Danish population of Tirup. Dental attrition was scored on all permanent molars from the Tirup skeletal sample. Scores were analyzed by means of logistic regression of the probability of having entered a given stage of wear for a given tooth in a way that is very similar to transition analysis. The primary determinant of dental attrition was age at death. In addition to age, the effects of sex, side, and dating were analyzed. In order to assess the homogeneity of the process of wearing teeth down, a third-order polynomial in age-at-death was also fitted to the transition probabilities. It was found that age is the single most important determinant of dental attrition, and that sex or side did not differentiate the rate of attrition. In several transitions, there was evidence of heterogeneity, indicating both random and systematic interpersonal differences in the rate of attrition and an association between the rate of attrition and age-at-death. It was found that attrition proceeded more quickly after AD 1300 than prior to that date. It is suggested that this was due to a possible general deterioration of living conditions in Northern Europe and an increased reliance on grain for food during the first half of the 14th century. The temporal effect on attrition rate accounts for some but not all the observed heterogeneity wear.

Leprosy and mortality in the Medieval Danish village of Tirup.
Leprosy was a well-recognized and dreaded disease in Denmark in the Middle Ages (AD 1000-1536). A large fraction of the population was affected by leprosy in the 13th century. This paper analyzes the correlation between signs of leprosy and risk of dying in the small Danish village of Tirup (AD 1150-1350). Seven different dichotomous osteological lesions indicative of leprosy are analyzed, and it is possible to score at least one of these conditions on 135 skeletons of adult or adolescent people (aged 14 or more). Scores were transformed to a statistic, lambda, indicating the likelihood that the person to whom the skeleton belonged suffered from leprosy. The analyses indicate that the prevalence of leprosy among adult people in Tirup was 26% (95% confidence interval, 17-35%). The lambda statistic indicates that people who died with signs of leprosy did not differ in the distribution of age at death from those who did not have such signs. Skeletons showing dental enamel hypoplasia were less likely to come from skeletons with high lambda-values. The association between lambda and dental enamel hypoplasia indicates a relationship between stress in early childhood (ages 1-6 years) and subsequent development of signs of leprosy.

Paleopathological study of hallux valgus.
Hallux valgus is the abnormal lateral deviation of the great toe. The principal cause is biomechanical, specifically the habitual use of footwear which constricts the toes. In this study, descriptions of the anatomical changes of hallux valgus from published cadaveric and clinical studies were used to generate criteria for identifying the condition in ancient skeletal remains. The value of systematic scoring of hallux valgus in paleopathology is illustrated using two British skeletal series, one dating from the earlier and one from the later Medieval period. It was found that hallux valgus was restricted to later Medieval burials. This appears consistent with archaeological and historical evidence for a rise in popularity, during the late Medieval period (at least among the richer social classes), of narrow, pointed shoes which would have constricted the toes.

Osteoarchaeological evidence for leprosy from western Central Asia.
Published reports of palaeopathological analyses of skeletal collections from Central Asia are, to date, scarce. During the macroscopic examination of skeletal remains dating to the early first millennium AD from the Ustyurt Plateau, Uzbekistan, diagnostic features suggestive of leprosy were found on one individual from Devkesken 6. This adult female exhibited rhinomaxillary changes indicative of leprosy: resorption of the anterior nasal spine, rounding and widening of the nasal aperture, erosion of the alveolar margin, loss of a maxillary incisor, and inflammatory changes in the hard palate. While it is unclear whether the bones of the hands and the feet from this individual were absent as a result of collection strategy or poor preservation, lesions affecting the tibia and fibula were recorded, and the ways in which they may be related to a diagnosis of leprosy are discussed. This is the first skeletal evidence of leprosy from Central Asia and raises questions not only about the spread of the disease in the past, but also about the living conditions of what traditionally were thought of as nomadic peoples.

The Vikings bare their filed teeth.
Finds of deliberate dental modification have for the first time been found in archaeological human skeletal material from Europe. The type of modification is a horizontally filed furrow on the frontal upper part of the tooth crown. The furrows are single or, more usually, multiple, and are found on the front teeth in the maxilla. The affected individuals are 24 men from the Viking Age (ca. 800-1050 AD), found in present day Sweden and Denmark. The marks are so well-made that it is most likely they were filed by a person of great skill. The reason for, and importance of, the furrows are obscure. The affected individuals may have belonged to a certain occupational group (such as tradesmen), or the furrows could have been pure decoration.

Comparison of child morbidity in two contrasting medieval cemeteries from Denmark.
This study compares associations between demographic profiles, long bone lengths, bone mineral content, and frequencies of stress indicators in the preadult populations of two medieval skeletal assemblages from Denmark. One is from a leprosarium, and thus probably represents a disadvantaged group (Naestved). The other comes from a normal, and in comparison rather privileged, medieval community (AEbelholt). Previous studies of the adult population indicated differences between the two skeletal collections with regard to mortality, dental size, and metabolic and specific infectious disease. The two samples were analyzed against the view known as the "osteological paradox" (Wood et al. [1992] Curr. Anthropol. 33:343-370), according to which skeletons displaying pathological modification are likely to represent the healthier individuals of a population, whereas those without lesions would have died without acquiring modifications as a result of a depressed immune response. Results reveal that older age groups among the preadults from Naestved are shorter and have less bone mineral content than their peers from AEbelholt. On average, the Naestved children have a higher prevalence of stress indicators, and in some cases display skeletal signs of leprosy. This is likely a result of the combination of compromised health and social disadvantage, thus supporting a more traditional interpretation. The study provides insights into the health of children from two different biocultural settings of medieval Danish society and illustrates the importance of comparing samples of single age groups.

Lateral angle: a method for sexing using the petrous bone.
We report on the results of applying the so-called lateral angle method for sex determination on skeletal remains. The lateral angle denotes the angle of the internal auditory canal in relation to the medial surface of the petrous part of the temporal bone. The method involves making a small cast of the proximal part of the internal acoustic canal and determining the angle at which the canal opens up to the surface of the petrous bone. The method has the great advantage of utilizing one of the sturdiest bone elements of the human skeleton, and may thus be especially suited for analyses of very fragmented skeletal remains or cremated bones, where the petrous bone may still be readily recognizable. The method was tested using a forensic sample of 113 petrous bones with known sex. Intra- and interobserver testing was also performed. We found a statistically significant difference in angle size between males and females (mean angle size of males, 39.3 degrees ; mean angle size of females, 48.2 degrees ; P < 0.001). There was no bilateral difference in angle size. In blind trials, 83.2% of petrous bones were assigned to the correct sex. We also tested the lateral angle method against an archaeological skeletal sample. True sex was not known for this sample; instead, sexing had been carried out by assessing pelvic and cranial morphology in independent trials. We found a higher concordance between the lateral angle and "pelvic" sex than for lateral angle and "cranial" sex. Finally, we note that subadult sexing may also be possible with this method.

mtDNA analysis of human remains from an early Danish Christian cemetery.
One of Denmark's earliest Christian cemeteries is Kongemarken, dating to around AD 1000-1250. A feature of early Scandinavian Christian cemeteries is sex segregation, with females buried on the northern sides and males on the southern sides. However, such separation was never complete; in the few early Christian cemeteries excavated in Scandinavia, there were always a few males placed on the north side, and some females on the south side. At Kongemarken, several males with juxtaposed females were found on the north side of the cemetery. Thus, to evaluate possible kinship relationships, and more general questions of population affinity, we analyzed mitochondrial DNA extracted from nine individuals excavated in two different areas within the cemetery: one male and four females from Area 1, and one male and three females from Area 2. Using stringent laboratory protocols, each individual was unequivocally assigned to a mitochondrial haplogroup. A surprising amount of haplogroup diversity was observed (Area 1: 1 U7 (male), 1 H, 1 I, 1 J, and 1 T2; Area 2: 2 H, 1 I, and 1 T, with one H being male); even the three subjects of haplogroup H were of different subtypes. This indicates that no subjects within each area were maternally related. The observed haplogroup, U7, while common in India and in western Siberian tribes, was not previously observed among present-day ethnic Scandinavians, and haplogroup I is rare (2%) in Scandinavia. These observations suggest that the individuals living in the Roskilde region 1,000 years ago were not all members of a tightly knit local population and comprised individuals with genetic links with populations that were from much farther away.

A pilot study of an intervention to prevent negative mental health consequences of forensic mortuary work.
This preliminary study investigated an intervention to mitigate mental health effects of forensic mortuary work. Fourteen peer-nominated opinion leaders at two mortuaries were trained in traumatic stress management methods. Effect was examined on variables assessing stress management and effects of traumatic stress. Sixty-two staff members participated. At baseline, opinion leaders did not differ from their colleagues on any variable. After intervention, opinion leaders had significantly better scores in comparison to coworkers in leisure repertoire, problem solving, and positive states of mind, but no difference in use of avoidance or social support, or in interpersonal relationships. Qualitative data suggests that opinion leaders had increased self-awareness, improved ability to tolerate unchangeable stressors, and increased belief in their ability to make changes.

[Stress deformations of skeletal remains from prehistoric cremation burials].
Vertebrae and parts of joints from long bones from prehistoric cremations of the Late Bronze Age and Early Iron Age are presented, showing marked deformations caused by pressure during cremation when bones exposed to temperatures of 400 degrees-500 degrees Centigrade display minimal hardness. The vertebrae with deformation of the arcus parts are only from the lower vertebral column; on account of the weight of this body region, this suggests that the corpse lay in the dorsal position at the place of cremation. The fact that there were deformed arches only on one side might suggest an irregular structure of the surface on which the corpse lay. In the prone position, i.e. in the absence of pressure caused by body weight, all vertebrae should be unaltered; alternatively, if cremation wood was piled on top of the corpse, the arches of thoracic and cervical vertebrae are also likely to be deformed. Deformations resulting from weight bearing were found in the joints of extremities only, with flattening of the heads of joints as well as fissures in the external layers of bones and compression into folds. Some bones show distinct even grooves caused by direct pressure, possibly resulting from the fixation of joint regions for cremation? Evidently the deformations caused by the weighting down of different skeletal regions provide hints that may help in the recognition of cremation rites. It would be helpful if experimental cremations could be performed to establish the pressure necessary to cause deformations.

[A contribution towards metrical sex determination of cremated and uncremated human bone remains, worked out at the pars petrosa ossis temporalis (author's transl)].
A new method for sex diagnosis is presented; the uni-, di-, and multivariate analysis of the Pars petrosa, which is a part of the temporal bone. This work was initiated because the Pars petrosa can be found very often among human cremation remains. Two different discriminant functions were worked out, and their comparison shows the great value of considering all the characteristics. Consideration of three measurements can give a sex determination of remarkable accuracy (about 80%). Even the uni- and divariate examinations yield important leads. The last part of this work deals with the possibility of applying the method to cremated bones. The most important point to consider is the shrinking of burnt bones. Appropriate new mean values of the first three measurements and an adapted sectioning point are given. Yet, even without shrinkage-correction the functions possess great reliability in the application on cremated material.

[Individual age determination using growth rings in the cementum of buried human teeth].
Incremental lines of the dental cementum were used for individual age determination in 102 teeth. 66 of them come from different historic periods, 15 teeth were cremated. 36 modern teeth of known age were use as controls. The incremental lines were investigated by use of 100 microns thin cross-sections of the root. Age determination by this method was possible in every tooth, independent of incinaration of various burial conditions. The individual age was determined by adding the mean value of the repeatedly counted incremental lines to the sex-specific eruption age of the tooth in question. Since average deviation from known age is +/- 3.23 years only, counting the incremental lines represent a very advantageous, quantitative method for individual age determination.

[Some new aspects in the study of human cremations (author's transl)].
Thermally induced reactions of bone mineral are outlined. The shrinkage of cremated bones is due to sintering of bone mineral. In an electron microscopic study changes of bone structure caused by thermal treatment and sintered mineral units are described. The problems of estimating the shrinkage factor and the use of cremation weight for identification and discussed. There is a significant difference between mean weights of cremations of senile males and females. The absolute difference indicates, that cremation weight is not a useful criterion for identification. Even in cremated bones, cuts and saw marks can be detected.
