Diaphyseal growth in a nineteenth century skeletal sample of subadults from St Thomas' church,Belleville, Ontario

This study presents skeletal growth data for a nineteenth century church cemetery sample from Belleville, Ontario. Skeletal growth profiles (SGPs), plotting measurements of growth against age estimated by tooth formation, were constructed for the sample. Means and confidence intervals for 1-year cohorts up to 12 years of age are presented for each of the long bones, the ilium and scapula. Comparison of the SGPs created for this sample with modern and archaeological samples demonstrates that the nineteenth century Belleville children followed a growth pattern similar to their modern counterparts, at least until 12 years of age. It is recommended that these data can be used by other investigators as a comparative sample of nineteenth century children; they can also be used as standards of growth for the purpose of estimating age from diaphyseal lengths for other archaeological samples of similar temporal context and population affinities. It is argued that confidence intervals rather than standard deviations be used to report variation, as the former controls for sample size as well as variance.     

Aging fetal and juvenile skeletons from Roman Period Egypt using basiocciput osteometrics

This paper tests the use of basiocciput osteometrics against those of femoral diaphyseal length and dental development for aging fetal and juvenile skeletal remains. The study sample consists of 39 fetal and juvenile skeletons recovered from Kellis 2, a Roman Period cemetery in Dakhleh, Egypt. The results add to the corpus of data supporting the reliability of this method for use in both bioarchaeological and forensic contexts. Copyright © 2002 John Wiley & Sons, Ltd.     

The Relationship Between Molar Wear and Age in an Early 19th Century AD Archaeological Human Skeletal Series of Documented Age at Death

Crown height of molar teeth was measured in a 19th century Dutch skeletal collection of known age at death. Results indicate an approximately linear relationship between crown height and age. A closer relationship between age and crown height exists for the mandibular than the maxillary molars. The mandibular molars wear at a faster rate than the maxillary molars. There is no evidence for any difference in wear rates between first, second and third molars. No effect on wear rate of ante-mortem loss of occlusal partner nor of dental caries could be detected. The rate of wear in the study material was markedly slower than that which characterizes most archaeological groups and the burials are drawn from a rather heterogeneous urban population; these factors mean that dental wear ageing would be expected to perform less well in this material than for most archaeological groups. Despite this, strong correlations were observed between molar wear and adult age at death; that this was the case despite circumstances unfavourable for its use supports the idea that dental wear is a reliable ageing technique for most archaeological skeletal material.     

Age estimation of children from prehistoric Southeast Asia: are the dental formation methods used appropriate?

Inter-population differences in skeletal and dental growth and maturation are acknowledged frequently in the biological anthropological literature. These growth differences have implications for the reliability of standards for the estimation of age at death of archaeological subadults. The number of archaeological projects that are recovering human burials from non-European contexts, including Southeast Asia, and the increasing interest in subadult bioarchaeological studies provides the impetus for investigating this issue of ageing subadult individuals from these populations. This paper aims to address some of the problems of the representativeness of ageing standards for non-European children in bioarchaeology. This is achieved through a literature review of the issue of growth variability and age estimation, and a basic comparison of the commonly applied age estimation method based on North American children with a dental formation study of modern Thai children. Although these studies do not employ similar methods the Thai study is the only comparable data available and therefore serves as a starting point to address these issues. The results raise an important question for bioarchaeologists of the appropriateness of available ageing methods. In addition this paper emphasises the need for the use of appropriate methodologies in the collection and presentation of dental formation data.     

Skeletal evidence for morbidity and mortality in Copper Age samples from northeastern Hungary

Analysis of 183 human skeletons representing the Copper Age in northeastern Hungary indicates slightly less morbidity and mortality than found in previous studies of later Bronze Age and Iron Age samples from the same area. Mean adult age at death was 33.4 years for males and 32.9 years for females. Life table reconstruction revealed a life expectancy at birth of about 28 years, and at age 15 of about 17 years. Frequencies of dental hypoplasia (<1%) and carious lesions (2.3%) were relatively low. Comparisons of the Copper Age data reported here with previously published studies of later Bronze Age and Iron Age samples from the same area revealed little or no change in life expectancy at age 15, long bone diaphyseal circumference, estimated living stature, frequencies of dental hypoplasia, alveolar abscesses, tooth loss, adult porotic hyperostosis or trauma. Temporal increases were detected in life expectancy at birth, dental caries frequency, cribra orbitalia, subadult periosteal lesions and vertebral osteoarthritis. The study is part of a larger effort to examine long‐term temporal changes in skeletal samples from that region. Copyright © 2008 John Wiley & Sons, Ltd.     

A dental study comparing age estimations of the human remains from the Swedish warship Vasa

The great Swedish warship Vasa capsized and sank in Stockholm harbour on her maiden voyage in 1628. The ship was raised from the seabed in 1961 and skeletal remains were recovered from at least 25 individuals, with teeth and jaws from 17 of them. The skeletal material was odontologically examined, including dental radiographs. Teeth lost both ante‐mortem and post‐mortem were recorded and variations in tooth anatomy noted. Acquired changes were recorded including enamel hypoplasia, attrition, dental caries and periodontal recession. Age estimations based on a separate odontological study, osteological changes and tooth attrition had been made in 1989. Ages were estimated additionally by three non‐destructive dental methods based on (a) the length of the apical translucent zone, (b) selected measurements both on intact teeth and from ratios on dental radiographs and (c) ratios of the length and width measurements on dental radiographs from selected teeth. Several sources of post‐mortem changes had been observed, among them vivianite in 33 teeth from four individuals. The results of the dental examination showed that few teeth had been lost ante‐mortem, there was a low caries rate and little loss of periodontal attachments. With few exceptions, there is fairly good agreement between the different methods of estimating age. Age estimates based on dental attrition were, however, significantly different from the other dental methods and age estimates calculated from apical translucency ought to be regarded with scepticism due to post‐mortem changes. The chronological ages of the victims will never be known, but age estimates based on all the age‐markers available will probably reach a fairly close approximation.

Original DocumentsNotarial Instrument,Dated A.D. 1322, Relating to Saint Nectan’s Chapel,in the Parish of St. Winnow,Near Lostwithiel,Cornwall

Our demographic knowledge of early Anglo-Saxon cemetery populations is highly valuable. This paper will present new demographic data from the Elsham and Cleatham cemeteries, both located in North Lincolnshire. These population structures will be compared with those recorded from contemporary cemeteries, including Sancton and Spong Hill. The observations made in this paper illustrate that the demographic profiles of cremation practicing groups are largely similar in nature. Two intriguing trends are verified by the Elsham and Cleatham assemblages, both of which include the under-representation of infants and males. This enlarged body of osteological data highlights that large amounts of information can be extracted from burned skeletal remains and can enhance our understanding of the demographic structure of cremation practicing groups in early Anglo-Saxon England.     

The periodontal disease status of the historical population of Assos

The science of anthropology obtains data on health, disease and death from ancient populations. Research on the skeletal remains of human teeth and surrounding tissues provides useful information on the evolutionary perspective of dental and periodontal diseases. The aim of this study was to determine the prevalence and severity of periodontal diseases in the skeletal remains of 33 Assos inhabitants of the 4th century BC. Three age groups were constituted for the studied population. Periodontal disease status was determined based on the textural and architectural variations of the interdental septum and the extent of bone loss. It was found that the prevalence of periodontal diseases increased with age. The severity of periodontal bone loss also increased with age and the mean alveolar bone loss between age groups was statistically significant (P = 0.004). This analysis of the dental health of ancient populations provides insights into the aetiology, patterns and distribution of periodontitis, which has a very complex disease pathogenesis.

Prediction Models for Age‐at‐Death Estimates for Calves,Using Unfused Epiphyses and Diaphyses

For cattle (Bos taurus), age estimations using dental criteria before the eruption of the first molar (3–8 months) have large error margins. This hampers archaeozoological investigation into perinatal mortality or the putative slaughtering of very young calves for milk exploitation. Previous ageing methods for subjuveniles have focused on the length of unfused bones, but it is rarely possible to use them because they are restricted to foetuses and because of the fragmentation of bones. This paper presents new age prediction models based on length, breadth and depth of post cranial bones produced from a dataset of modern calves (n = 27). This reference collection was compiled from material of known age at death, sex and breed from collections in Britain, France, Germany and Switzerland. Linear regression models were constructed using the modern data for age prediction, and these models were then successfully tested and assessed using a Middle Neolithic assemblage of complete calves' skeletons from Bourguignon‐Lès‐Morey, France. From the assessment, the astragalus and metapodials were determined to be the most reliable bones, and the femur was the worst. Measurements of the epiphyseal and distal elements and depth measurements were the most reliable. For ages before 12 months, these models can provide ±1 month age estimates.

Subadult Age‐at‐Death Estimation From the Human Calcaneus

The estimation of age from subadult skeletal remains relies on the measurement of bones, which when unavailable or damaged hampers the ability to generate a reliable age estimate. The goal of this project was to demonstrate two methods for estimating age at death from the developing human calcaneus. These methods are generated from a sample of 32 European American and African American males and females with ages ranging from 1 to 19 years from the Hamann–Todd Collection. The first method was based on linear regression from two standard measurements of the calcaneus (maximum length and middle breadth); the second was based on transition analysis of fusion states of the calcaneal epiphysis. Results suggest that both methods perform well in estimating subadult age at death. Additional testing with larger contemporary samples would likely increase the accuracy of both methods.

The person‐years construct: ageing and the prevalence of health related phenomena from skeletal samples

Age has the ability to confound prevalence data. Yet, the effects of length of exposure and age‐structure on such prevalence data are seldom directly measured in osteological studies. Here we describe a simple method that addresses both issues through the use of person‐years, and treatment of data in the case of rare events as Poisson counts. We advocate use of person‐years as a denominator when comparing skeletal data that involves the cumulative insults of ageing (e.g. fractures, dental caries, and other chronic diseases such as osteoarthritis).

Sex estimation using cervical dental measurements in an archaeological population from Iran

Sex estimation of skeletal remains is one of the major components of forensic identification of unknown individuals. Teeth are a potential source of information on sex and are often recovered in archaeological or forensic contexts due to their post-mortem longevity. Currently, there is limited data on dental sexual dimorphism of archaeological populations from Iran. This paper represents the first study to provide a dental sex estimation method for Iron Age populations. The current study was conducted on the skeletal remains of 143 adults from two Iron Age populations in close temporal and geographic proximity in the Solduz Valley (West Azerbaijan Province of Iran). Mesiodistal and buccolingual cervical measurements of 1334 maxillary and mandibular teeth were used to investigate the degree of sexual dimorphism in permanent dentition and to assess their applicability in sex estimation. Data was analysed using discriminant function analysis (SPSS 23), and posterior probabilities were calculated for all produced formulae. The results showed that incisors and canines were the most sexually dimorphic teeth, providing percentages of correct sex classification between 86.4 and 100 % depending on the measurement used. The combination of canines and other teeth improved significantly the level of correct sex classification. The highest percentages of sex classification were obtained by the combination of canines and incisors (100 %) and canines and molars (92.3 %). The present study provided the first reference standards for sex estimation using odontometric data in an Iranian archaeological population. Cervical measurements were found to be of value for sex assessment, and the method presented here can be a useful tool for establishing accurate demographic data from skeletal remains of the Iron Age from Iran.     

Dolnı́ Věstonice 15: Pathology and Persistence in the Pavlovian

Several lines of archaeological and human palaeontological data from the Moravian earlier Gravettian (or Pavlovian) indicate a high level of mobility among these earlier Upper Palaeolithic human populations. The congenitally abnormal young adult Dolnı́ Věstonice 15 human remains support this pattern. Dolnı́ Věstonice 15 suffered serious developmental abnormalities, most likely as a result of the X-linked dominant form of chondrodysplasia calcificans punctata, that included pronounced infantile and minor later childhood developmental defects of dental enamel (enamel hypoplasia), asymmetrical curvature and angular deformities of the proximal femora, asymmetrical shortening of the femora, a diaphyseal deformity of the distal right humerus, a probable healed left ulnar fracture with associated deformity of the radial diaphysis, elevated length asymmetries of the forearms, and an unusual pattern of anomalies of tooth position and number. These are combined with trivial intervertebral articular degenerations, plus localized pronounced osteoarthritis of the right glenohumeral joint and right second and fifth ray hand proximal interphalangeal joints. Yet, there is little asymmetry of the lower limbs distal of the mid-femora, and both diaphyseal hypertrophy of the humeri, femora and tibiae and relative arm and leg muscle attachment size and moment arms indicate a level of skeletal hypertrophy average to high for an earlier Upper Palaeolithic human. The severe upper limb osteoarthritis may indicate a pattern of pronounced and repetitive carrying or dragging of heavy loads. These data indicate the ability of the population to keep a severely affected individual alive through development, yet they also emphasize the necessity for all individuals to participate actively in the elevated mobility and overall activity levels of these earlier Upper Palaeolithic human populations.     

Sugar Consumption,Dental Health and Foodways in Late Medieval Iin Hamina and Early Modern Oulu,Northern Finland

This article examines the modernization of northern Finnish food culture, especially in 17th- and 18th-century urban Oulu, by applying the methods of archaeology and history research. During the 17th century, the food culture was still quite conservative. Coffee, sugar, wheat flour, and fruit began entering the diet of affluent northern Finnish people from the 18th century onwards. The food culture of Oulu inhabitants is studied by comparing dental material retrieved from Oulu Cathedral graveyard to data obtained from historical document sources. A comparison point to the early modern bone material of Oulu is provided by late Middle Ages material from Ii, which lies north of Oulu on the coast of the Gulf of Bothnia. Carbohydrate consumption is related to many dental conditions, such as caries and calculus, which can be traced in archaeological human skeletal remains. The diets of males and females, as well as the diets of adults and children, are compared, in order to retrieve information on the emerging consumption of sugar in different groups, such as gender and age groups. The relationship between carbohydrate consumption and class identity in northern Finland is discussed.     

The Retromolar Space: A Morphological Curiosity Observed Amongst the Protohistoric Arikara and Mandan

The retromolar space (RMS), defined in palaeoanthropology as a space posterior to the third molar, between the distal edge of the tooth and the anterior margin of the ascending ramus when the mandible is held in lateral view, has been described as an autapomorphic trait unique to Neanderthals despite its presence in anatomically modern humans. This study examined RMS prevalence in a sample of protohistoric Arikara and Mandan Amerindians to determine what craniofacial morphology is correlated with the RMS. It was hypothesised that the feature would be present in the Amerindians studied and associated with a long cranial length, a large nasal height, midfacial prognathism, a broad mandible, and dental wear. The results indicated that RMSs were present in the Arikara and Mandan and significantly correlated with cranial length, cranial breadth, nasal height, bizygomatic breadth, basion‐nasion length, basion‐nasiospinale, mandible length, gonial angle, bigonial breadth, and dental wear. Thus, RMSs are associated with a dolichocephalic skull, wide cranial and facial breadth, a prognathic face, large nose and a corresponding wide and long mandible with a reduced gonial angle. This suggests that the RMS is the result of these features merging together in the craniofacial complex and should not be considered a Neanderthal autapomorphy.

Growth curves of immature bones from a Scottish island population of sixteenth to mid-nineteenth century: Limb-bone diaphyses and some bones of the hand and foot

Growth curves were prepared for length of the diaphyses of the six major long bones of the limbs and for length of the calcaneus, talus, cuboid and the first metacarpals and metatarsals, of ages up to 20 years including several immature and many full-term fetuses. Most curves showed what appears to be a consistent adolescent growth spurt at about 17 years, but the number of specimens supporting these parts of the curves is too small for the validity of this spurt to be beyond doubt. The fetal diaphysis lengths were similar to those of Fazekas and Kósa and other recent populations but, compared with curves prepared from the Maresh radiographic data for recent caucasoids, the island diaphyseal growth rate, starting at about 4 months after birth, fell progressively behind so that, by 18 years for example, the femur was 90 mm shorter and the humerus 60 mm shorter than the Maresh equivalents. These findings accord with the short stature of the island adults (male mean 166.2 cm). The growth curves were closer to those of some ancient peoples, Amerindian, caucasoid and negroid, than to contemporary caucasoid. There is evidence of a secular change in growth in this island region because the calculated mean height at 18 years of this earlier island population is at the present time achieved by boys by about 14 years of age. Thus it is argued that the earlier population was affected by stunting factors. Although there is no skeletal evidence of malnutrition, there is plenty of evidence that the way of life was full of hardship in which the children shared. They took a full part in the arduous work involved in farming marginal-quality land; the houses were damp, cold, smoky and dark; they were overcrowded although, mainly because of the high infant-mortality rate, families were not large.     

A leprous skeleton of the 7th century from Eccles,Kent, and the present evidence of leprosy in early Britain

A male skeleton of 7th century date from the Anglo-Saxon cemetery at Eccles, Kent, is described. Certain skeletal changes associated with leprosy are manifest. The disease is discussed in its palaeopathological context and this case in relation to the few other cases of the disease hitherto diagnosed in Great Britain.     

An investigation of cortical bone loss and fracture patterns in the neolithic community of Çatalhöyük,Turkey using metacarpal radiogrammetry

Bioarchaeologists have conducted numerous studies on human skeletal remains using metacarpal cortical bone radiogrammetry. This method allows cortical thickness of the second metacarpal to be quantified. As a sensitive index of bone health metacarpal cortical thickness is evaluated in the context of functional adaptations, growth, ageing and bone loss in osteoporosis, as well as used as a reliable indicator of fracture risk. The focus of this study is an examination of the widely used calculation that expresses second metacarpal cortical bone values, followed by an examination of age and sex-related patterns of cortical bone loss and skeletal fragility fracture in a Neolithic archaeological skeletal sample from Çatalhöyük, Turkey. Using metacarpal radiogrammetry, 49 adult metacarpals (f = 27 m = 22) were examined. Data were collected for size variables, length (L) and total bone width (TW) as well as quantity variables, medullary width (MW) and cortical thickness (CT). These parameters were then used to calculate the widely used cortical index (CI) and two new indices expressing medullary width and cortical bone thickness in relation to length (medullary width index, MWI and cortical thickness index, CTI). The ratios were then used to explore age- and sex-related cortical bone loss and fragility fracture patterns amongst the inhabitants of Çatalhöyük. Çatalhöyük males and females demonstrate an inverse relationship where CTI decreases as age and MWI increase. Analyses indicate statistically significant age-related change in MWI amongst the oldest females. Despite age-related loss of bone, no typical fragility fractures are observed. We discuss the role of ageing and lifestyle factors at Çatalhöyük that may have been beneficial to skeletal health and a reduction in the risk of fragility fracture.     

A comparison of different non-destructive methods of age estimation in skeletal material

The skeletal remains of unidentifiable persons, recovered in recent years from the churchyard adjoining the House of Correction in Oslo, included 91 instances in which the maxillae and/or mandibles had been preserved, and these were examined. The length of the apical translucent zone in unsectioned teeth and the amount of secondary dentine deposit have been regarded as two of the most reliable factors in odontological age estimation. This study has used two methods, each using one of these factors, on single-rooted teeth from, respectively, 78 and 76 individuals. The distribution of age at death, as estimated from the two dental methods and from anthropological criteria, was then compared with the distribution of age at death of 380 individuals recorded in the church register for the House of Correction. Age calculations from secondary dentine, measured indirectly on dental radiographs of premolars, and estimates based on anthropological criteria both seemed to approximate to the chronological age distribution better than age estimates based on the length of the apical translucent zone. Statistical analyses indicated that all three methods of age estimation were significantly different (p<0.05). When compared with the church register, each method assigned a lower percentage of individuals to the younger and older age-groups and a higher percentage to those in the middle. No statistical difference could be found between the age distribution from the church register and estimates from either anthropological criteria or dental radiographs; but when age estimates based on these two latter methods were compared, 39.5 per cent differed by more than 10 years.
