The Raymond A. Dart Collection of Human Skeletons (Dart Collection) is housed in the School of Anatomical Sciences at the University of the Witwatersrand, Johannesburg, South Africa, and comprises one of the largest documented cadaver‐derived human skeletal assemblages in the world. This collection originated in the early 1920s as a result of the efforts of Raymond Dart and continues to grow. The skeletons included represent varied indigenous and immigrant populations from southern Africa, Europe and Asia. This contribution documents the history of the collection and provides an updated inventory and demographic assessment of this valuable research collection. According to a recent inventory the Dart Collection currently comprises 2,605 skeletons representing individuals from regional SA African (76%), White (15%), Coloured (4%) and Indian (0.3%) populations. A large proportion of the skeletons (71%) represent males. The recorded ages at death range from the first year to over 100 years of age, but the majority of individuals died between the ages of 20 and 70. The Dart Collection has been affected by collection procedures based on availability. All of the cadavers collected before 1958, and large proportions subsequently, were derived from unclaimed bodies in regional South African hospitals. Some details of documentation (age at death, population group) are estimates and some aspects of the collection demographics (sex ratios) do not closely reflect any living South African population. Our inventory and analysis of the Dart Collection is aimed to assist researchers planning research on the materials from this collection. Am J Phys Anthropol, 2009. © 2009 Wiley‐Liss, Inc. 相似文献

Comprehending violence among bioarchaeological and historical groups is a topic of recent interest among biological anthropologists. This research examines trauma among African American and Euro-American males of low socioeconomic status born between 1825 and 1877. A total of 651 male skeletons from the Cobb, Terry, and Hamann-Todd anatomical collections were macroscopically evaluated for skeletal trauma, based on the presence of fractures and weapon-related wounds, and statistically analyzed according to ancestry, birth (Antebellum, Civil War, Reconstruction), combined ancestry - birth, and collection cohorts. Results indicated that African Americans and Euro-Americans expressed ethnic differences in regard to interpersonal violence. To interpret these disparities, documentary data were used to reconstruct the socioeconomic and cultural environment of these individuals. This research emphasizes the importance of evaluating skeletal data within the context of class, culture, and environment so that behavioral patterns observed in the skeleton can be better understood. 相似文献

The work reported here is the beginning of an attempt to determine whether data on skeletal aging changes derived from the Terry collection (Smithsonian Institution) can safely be applied to present-day clinical and forensic problems. Measurements made on radiographs of the proximal third of the right femur below the greater trochanter were compared in three groups of American white females: Terry collection “regulars,” Terry collection willed, and GW (George Washington University Medical Center) willed. Mean birth year for the Terry regulars was 1883, whereas the mean birth year for Terry and GW willed was 1910. Terry willed femora are longer than those of Terry regulars, but not more robust. The two groups show opposing secular trends in femoral length, and in this respect the Terry regulars appear closer to the general U.S. population. In two indices of relative medullary cavity size (which reflect changes in cortical thickness as well as internal and external diameters) all three groups agree in showing age-related increase of medullary diameters, greater increase in the anterior–posterior dimension, and greatest amount of increase at diaphyseal levels. The major difference between groups is in timing, with medullary cavity expansion becoming evident at least a decade earlier and leading to greater eventual loss of cortical thickness in the willed groups. 相似文献

Assessment of race from the pelvis 总被引:5,自引:0,他引:5

Racial assessment of human postcranial skeletal remains has been a major concern for forensic and skeletal anthropologists. Materials (N = 400) of the present study are from the Terry Collection and consist of 100 black and white American pelves of both sex with known age and race. Measurements were taken from the articulated pelves. Results of discriminant function analysis indicate classificatory accuracy may be as high as 88%. Transverse pelvic breadth contributes more to the function than biiliac breadth and antero-posterior height. The females are more easily assessed racially than males. Although a highly reliable classification is produced, the results of the study should be employed with caution, as samples were of questionable nutritional status and of low socioeconomic class. 相似文献

Diploic veins (Canales diploicae), which were identified in dogs by Dupuytren more than 200 years ago (Hecker [1845] Die anatomische Verhaltnisse und Krankheiten der Venae diploicae und Vasa emissaria. Erfahrungen und Abhandlungen im Gebiete der Chirurgie und Augenheilkunde. Erlangen), have remained inadequately understood and scantily referenced in the anatomical and anthropological literature. The tunnels formed by diploic veins are among the few known skeletal markers of soft tissue alteration. Protected by two bony laminae, diploic vein tunnels often resist postdepositional destruction and may provide a new way to assess living and extinct hominid populations. This basic research was carried out to enable future utilization of the diploic venous channels in anthropologic research. In the present study, diploic venous channels were observed radiographically in 108 human adults aged 19 years and above, 18 infants and children aged 1-18 years (Hamann-Todd Osteological Collection), eight fetuses aged 7-9 months (the Johns Hopkins Collection), and seven nonhuman primates (Hamann-Todd Osteological Collection). In addition, seven documented cases of parents and children were radiographed for genetic evaluation (Osteological Collection of The Hungarian Natural History Museum). Five distinct diploic distribution patterns were identified and described in this study. This was at variance with the impressions reported in dissection-based studies. Independence of diploic vein pattern from demographic (gender and age) and size factors and their tendency to be symmetrical make them amenable and reliable traits for skeletal population study. Diploic vein patterns appeared to be more complicated in humans than in nonhuman primates, raising the possibility of future phylogenetic applications. 相似文献

The cranial base can be used to determine the sex of fragmentary or deformed skulls. An initial study used nine measurements taken from 100 crania in the Terry Collection. The sample was divided equally by race and sex. Six regression models were formulated that predicted correctly the sex of the sample with 71-90% accuracy. In a separate test, a control sample of 20 skulls, also drawn from the Terry Collection but not involved with formulating the regression equations, was correctly classified with 70-85% accuracy. 相似文献

Skull anatomy and development have been extensively studied due to their significance in evolutionary biology, forensic anthropology, and clinical medicine. Bone collections are an indispensable resource for conducting such anthropological and anatomical studies. However, worldwide there are only few skull collections containing specimens covering the entire fetal and postnatal period. Herein we describe the Zagreb Skull Collection, an identified collection comprising more than 1100 skulls and skull bone sets from the early fetal period to centenarians. The Zagreb Skull Collection consists of two main parts: the unique Collection of Skull Bones containing 386 sets of separated skull bones from the early fetal period to adulthood and the Collection of Skulls containing 742 skulls (age range 4–101 years). The collection was the core source for numerous anatomical studies on the development, postnatal changes, and anatomical variations of the skull. However, the Zagreb Skull Collection is still an underexploited resource for anthropological, forensic, and anatomical studies with translatability to contemporary clinical practice. 相似文献

This study analyzed skeletal health disparities among African American and Euro-American males of low socioeconomic status born between 1825 and 1877. A total of 651 skeletons from the Cobb, Hamann-Todd, and Terry anatomical collections were macroscopically examined for skeletal pathologies related to dietary deficiencies and disease. Individuals were separated into age, ancestry, birth (Antebellum, Civil War, Pre-Reconstruction, and Reconstruction), combined ancestry/birth, enslaved versus liberated, and collection cohorts. These groups were statistically evaluated using ANOVA and χ(2) analyses to determine if age, ethnic, and temporal differences existed. Results indicated that African Americans, especially those born during Reconstruction, had significantly higher frequencies of tuberculosis (P = 0.004) and treponematosis (P = 0.006) than Euro-Americans. Historical sources are important in contextualizing why these different ethnic and temporal patterns were present, pointing to environmental conditions related to enslavement, postliberation migration to the industrialized North, crowded urban living conditions, and poor sanitation. 相似文献

The objective of this paper is to test a revised method of age estimation based on the morphology of the auricular surface recently proposed by Buckberry and Chamberlain ([2002] Am. J. Phys. Anthropol. 119:231-239). The study sample consists of 309 individuals of known sex, age, and race from the Terry and Huntington Collections. Auricular surfaces were scored using the revised technique to determine whether it is equally applicable to both sexes as well as blacks and whites. The auricular surfaces of the same individuals were also scored using the original method of auricular surface scoring developed by Lovejoy et al. ([1985] Am. J. Phys. Anthropol. 68:15-28) to determine whether the revised technique is comparable to the original method in terms of accuracy. Results show that the revised method is equally applicable to males and females as well as blacks and whites. The revised method is less accurate than the original method for individuals between 20-49 years of age, but more accurate for individuals between 50-69 years of age. 相似文献

This study completes previously reported ages for timing of epiphyseal union in the postcranial skeleton in a recent sample, with data from the scapula, clavicle, humerus, radius, and ulna. A sample of 121 individuals between the ages of 9 and 29 (females = 65, males = 56) was derived from the Lisbon documented skeletal collection. Epiphyseal union was scored at 16 anatomical locations, using a three-stage scheme: 1) no union; 2) partial union; and 3) completed union, all traces of fusion having disappeared. In the upper limb, the epiphyses of the elbow are the first to fuse at around 11 to 15 years of age, followed by those of the shoulder and wrist. In the scapular girdle, the coracoid area is the first to fuse, followed by the glenoid surface and remaining epiphyses, with the medial clavicle fusing last, by the age of 25-27. There is a sex difference in maturation, with females showing an advance relative to males of about 2 years in the upper limb. Sex differences in maturation are less noticeable in the scapular girdle, but data suggest that females are also ahead of males. Results suggest overall similar age ranges for stages of union as previous dry bone observations, but some studies show significant divergences which seem to derive from methodological issues. Although some radiographic reference standards provide comparable age ranges, they should probably be avoided when aging skeletal remains. 相似文献

Previous research (Tague [1994] Am. J. Phys. Anthropol. 95:27–40) has shown an age effect in pubic bone length among adult women. Tague found that in three prehistoric Native American skeletal samples, women aged 18–24 had a significantly shorter linea terminalis than did women aged 25 and older. The purpose of this research is to determine whether such a difference can be discerned in other female skeletal samples. Three female skeletal samples were used in this analysis: 75 African-American and 42 European-American females aged 18–39 from the Hamann-Todd Collection (collected between 1893 and 1938; Iscan, 1990) and 99 African-American females aged 18–39 from the Terry Collection (collected between 1914 and 1965; Cobb, 1933; Iscan, 1990). Several chord measurements of pubic bone length along the linea terminalis were analyzed by one-tailed t-tests of the separate samples subdivided into two age groups: 18–24 and 25–39 years. Of 15 comparisons between age groups, none differed significantly by age group within each sample. It is concluded that the observed significant difference in pubic bone length in the Native American female skeletal samples cannot be replicated in other samples and that there is no age effect on pubic bone length in the samples tested in this analysis. Tague's findings reflect either the occurrence of late menarche in prehistoric populations or differential survivorship. Am J Phys Anthropol 106:323–328, 1998. © 1998 Wiley-Liss, Inc. 相似文献

A large collection of identified human skeletons curated at the Bocage Museum (National Museum of Natural History, Lisbon, Portugal) has remained in relative anonymity since its collecting protocol was initiated in the 1980s. This collection originates from modern cemetery sources and is comprised of 1,692 skeletons with basic documentary data (age at death, place of birth, occupation, place of residence, and date and cause of death). At present, this information is more readily available for 699 individuals. The remaining 993 are in the process of being fully documented. The skeletons consist largely of Portuguese nationals who lived in the 19th and 20th centuries (1805-1975) in Lisbon. Both sexes are equally represented, and ages at death range from birth to 98 years, including 92 subadults (<20 years old). 相似文献

Due to disparity regarding the age at which skeletal maturation of the spheno‐occipital synchondrosis occurs in forensic and biological literature, this study provides recalibrated multislice computed tomography (MSCT) age standards for the Australian (Queensland) population, using a Bayesian statistical approach. The sample comprises retrospective cranial/cervical MSCT scans obtained from 448 males and 416 females aged birth to 20 years from the Skeletal Biology and Forensic Anthropology Research Osteological Database. Fusion status of the synchondrosis was scored using a modified six‐stage scoring tier on an MSCT platform, with negligible observer error (κ = 0.911 ± 0.04, intraclass correlation coefficient = 0.994). Bayesian transition analysis indicates that females are most likely to transition to complete fusion at 13.1 years and males at 15.6 years. Posterior densities were derived for each morphological stage, with complete fusion of the synchondrosis attained in all Queensland males over 16.3 years of age and females aged 13.8 years and older. The results demonstrate significant sexual dimorphism in synchondrosis fusion and are suggestive of intrapopulation variation between major geographic regions in Australia. This study contributes to the growing repository of contemporary anthropological standards calibrated for the Queensland milieu to improve the efficacy of the coronial process for medicolegal death investigation. As a stand‐alone age indicator, the basicranial synchondrosis may be consulted as an exclusion criterion when determining the age of majority that constitutes 17 years in Queensland forensic practice.

Alcide d’Orbigny made his mark in the history of French Palaeontology by becoming, in 1853, the first holder of the chair of Palaeontology at the Museum of Natural History, Paris. His work on foraminifera made him one of the pioneers of Micropalaeontology. Today, his original collection of foraminifera, bought by the Museum after his death, represents one of the most prestigious collections of the institution. However, for more than a century, it had been relegated to the reserves and to the good will of a few enthusiasts, while the priority of research study was given to the large vertebrate fossils. It survived the conflicts that affected the Palaeontology department, and was moved in response to construction works, wars and natural accidents such as the great flood of 1910. These different events, combined with inappropriate storage conditions, probably caused the fragility of the specimens. In order to better understand this phenomenon, known as Byne's decay, research has been undertaken to reconstruct the various storage points of the collection from its acquisition to the present day. This article aims to demonstrate the close link between the Foraminifera Collection and the history of the chair of Palaeontology, through evidence drawn from the archives of the Palaeontology laboratory and the Museum of Natural History. 相似文献

I measured the bodies of vertebrae L3 and L4 of 338 skeletons from the Terry collection in the Smithsonian Institution, including Blacks and Whites, males and females, aged from 20 to 90 years. Transverse breadths of the upper and lower endplates (excluding osteophytes) and minimum transverse breadths all increase with age. In general, the greater broadening occurs in the endplates, but the middle of the body also broadens to such a degree that there is no demonstrable increase in vertebral “flaring” with age. In males, posterior body height decreases relative to anterior height, so that the lumbar bodies become more wedge-shaped with age, but females show essentially no change. Anterior height decreases in proportion to minimum breadth, so that the lumbar bodies become relatively lower and broader, and this change is significantly correlated with age in all groups. Midbody height decreases relative to anterior height, so that Nordin's biconcavity index is reduced with age. The increase in biconcavity remains evident even when average anterior-posterior height is used to calculate the index. At all age levels a high percentage of individuals have biconcavity indices of 80% or less, indicating that Nordin's standard of normality for this index, established from measurement on radiographs of the living, should be revised downward for use in evaluating osteoporosis in skeletal populations. 相似文献

The purpose of this study is to obtain demographic data regarding the medieval population buried at the Yuigahama-minami site in Kamakura, Japan, and to detect a secular trend in the life expectancy of Japanese population over the last several thousand years. The Yuigahama-minami skeletal sample consists of 260 individuals, including 98 subadults (under 20 years old) and 162 adults. A Yuigahama-minami abridged life-table analysis yielded a life expectancy at birth (e0) of 24.0 years for both sexes, a life expectancy at age 15 years (e15) of 15.8 years for males, and an e15 of 18.0 years for females. The reliability of the estimated e0 was confirmed by analysis of the juvenility index. Demographic profiles comparing the Yuigahama-minami series with other skeletal series indicated that both the survivorship curve and life expectancy of the Yuigahama-minami sample are similar to those of the Mesolithic-Neolithic Jomon population, but are far lower than those of the early modern Edo population. These comparisons strongly suggest that life expectancy changed little over the thousands of years between the Mesolithic-Neolithic Jomon and medieval periods, but then improved remarkably during the few hundred years between the medieval period and early modern Edo period. The short-lived tendency of the Yuigahama-minami sample does not contradict the archaeological hypothesis of unsanitary living conditions in medieval Kamakura. This is the first investigation to address the demographic features of a medieval population in Japan, and will help refine our understanding of long-term trends in the demographic profiles of inhabitants of Japan. 相似文献

Rhesus monkeys (Macaca mulatta) at the Nanwan peninsula of Hainan Island, China, have been observed in the field for 25 years, and have been studied intensively for eight years, beginning in 1981. There were about 115 monkeys in 5 natural groups when the Nanwan Reserve was founded in 1965. From 1965 to 1984, the number of groups increased from 5 to 19, and the total population increased from 115 to 930 individuals, an annual population increase of 12.7%. From 1984 to 1987, the population continued a slower rate of increase (8.9%) to approximately 1200 monkeys in 20 groups. The home ranges of each monkey group at Nanwan varied from 0.16 to 0.72 km2, with a mean and standard deviation of 0.37 ± 0.18. The size of the home range of the rhesus was affected by the quality of vegetation and rhesus population density. The average birth rate per year was 77.8 ± 13.9%, varying from 53.8% to 100% since 1978. From 1978, the birth rates of two food provisioned groups were higher in alternate years (x? = 91.7%) and lower in intervening years (x? = 68.8%; P = <0.01). A minority (26.5%) of females have given birth at 4 years of age, most at 5 years. The sex ratio of newborns in any one year varied from 0.3 to 3.5 males to females, with a mean and standard error of 1.09 ± 0.37 males to females. 相似文献

BACKGROUND: Little is known about the degree to which baboons, an important animal model in skeletal research, spontaneously experience age-related osteopenia and osteoporosis. METHODS: We measured bone mineral density (BMD) in 667 baboons, assigned T-scores to older animals based on sex-specific young adult reference groups, and compared reproductive history in older females with low BMD to those with normal BMD. RESULTS: Approximately 25% of older baboon females were osteopenic. No females or males were osteoporotic. Neither parity nor interbirth interval spine clearly distinguished low vs. normal BMD groups. Intersite correspondence in low BMD was highest between sites in the same region rather than sites of the same bone type. CONCLUSION: As with humans, osteopenia is common among older females. The absence of osteoporotic animals may be due to colony maintenance resulting in truncation of the aged population and selection for healthier animals in the oldest ranges. 相似文献
