Dental pathology and diet at Apollonia,a Greek colony on the Black Sea

Dental pathology has the potential to provide insight into the composition of the diet and to reveal dietary differences based on age, sex and social status. Human skeletal remains from the Greek colonial site of Apollonia (5^th to 2^nd centuries BC) on the Black Sea coast of Bulgaria were analysed for various forms of dental pathology in order to: assess the prevalence of dental disease in the population; compare the dental pathology data from Apollonia with dietary data derived from ancient literary texts and from previous stable isotopic analysis of the colonists' remains; explore variations in dental disease with respect to age and sex; and compare the prevalence of dental pathology in the Apollonians with that of other Greek populations. The composition of the diet, as indicated by the dental pathology data, is consistent with the stable isotopic evidence from Apollonia and with the ancient literary texts, both of which indicate the consumption of a relatively soft, high carbohydrate diet. The higher frequency of dental caries, abscesses, calculus, and antemortem tooth loss in older adults compared with younger ones reflects the age‐progressive nature of these conditions. The lack of significant sex differences in caries, abscesses, calculus and tooth loss corresponds with the stable carbon and nitrogen isotopic data derived from bone collagen, which indicate no significant sex differences in the consumption of dietary protein. In contrast, these findings conflict with the ancient literary texts, which refer to distinct dietary differences between males and females, and with the stable carbon isotopic values derived from bone carbonate, which indicate sex differences with respect to the overall diet. Despite the lack of marked sex differences in dental pathology, overall trends point to subtle dietary differences between males and females. A greater degree of tooth wear in males also hints at possible sex differences in the use of the teeth as tools. Copyright © 2007 John Wiley & Sons, Ltd.     

Frequency of Complete Cleft Sacra in a Native American Sample

The purpose of this paper is to contribute to the current understanding of the variability of complete sacral clefts in human populations by presenting new data on a large prehistoric and historic Native American skeletal sample (n = 1943). Results are examined by age, sex, time period, and regional distribution and compared with reported frequencies of complete sacral clefts in other modern, historic, and ancient populations. In all, 1.6% of the sample exhibited complete sacral clefts, including 2.1% of males and 1.1% of females. Although males exhibit a frequency twice as high as females, this difference is not statistically significant. However, within the Alaskan sample, the sex difference was significant (p = 0.002), with 3.4% of males and 0.5% of females exhibiting complete clefts; these differences may be related to mechanical influences during growth and development in males. Differences among age groups are not significant. Regional comparisons among Alaska, Eastern Woodlands, Great Basin/Northwest/California, Great Plains, and Southwest showed no significant differences overall, but Alaska (2.2%) and Great Plains (0.5%) do show a significant difference (p = 0.024). No significant differences were found between prehistoric, protohistoric, and historic/recent samples, suggesting a lack of a secular trend in frequency of complete sacral clefts in Native American populations. One individual exhibited an enlarged canal, which may be indicative of a more severe condition. Copyright © 2012 John Wiley & Sons, Ltd.     

Enamel hypoplasia in Danish and Lithuanian Late Medieval/Early Modern samples: a possible reflection of child morbidity and mortality patterns

Numerous studies and various interpretations of the prevalence of linear enamel hypoplasias (LEH) based on populations living in different cultural and economic conditions are causing some confusion and raising doubts about whether or not such LEH are reliable indicators of life conditions. An analysis of LEH prevalence patterns was performed on the adults of three populations: Tirup—a Danish Medieval rural population of the 12–14th centuries (131 individuals), Subačiaus str. in Vilnius—a Lithuanian Late Medieval urban population of the 16–17th centuries (88 individuals), and the aristocracy—a Lithuanian pooled sample population from several churches of the 15–18th centuries (66 individuals). Statistical testing of the influence of population affinity, sex and age at death was also performed. Since the same investigator scored all the samples, possible inter‐observer error bias was minimized. In all the populations, LEH formation ages were similar. Statistically significant sex differences were found only in the aristocratic sample (with higher male frequency). It was found that the town population was characterized by the highest frequency of affected individuals, with the highest severity and highest number of stress episodes per individual. A reliable relationship with age at death was found only in the town sample: individuals with more numerous and more marked LEH had shorter life expectancies in adulthood. Different “most vulnerable years” for subsequent life expectancies were noted for different populations. A tentative explanation of these differences could be the pooled effect of differential morbidity and mortality. It seems that the rural population experienced the highest morbidity and nutrition deficiency as well as the highest child mortality whereas, in the urban sample, high morbidity was accompanied by a lower child mortality. Both lower morbidity and mortality seem to be characteristic for the aristocracy. Copyright © 2002 John Wiley & Sons, Ltd.     

Fur-bearing species and Scottish islands

Analysis of a database comprising archaeological records of fur-bearing species in Scotland has highlighted the presence of foxes, badgers and other mustelids in areas outside their modern-day geographic range. Of particular interest is the apparent presence of foxes on Orkney for a number of centuries, from perhaps the last few centuries BC to the mid to late first millennium AD, pine marten on Orkney in the Neolithic, and badgers on the Outer Hebrides in the Early Bronze Age and 6–7th centuries AD. While zooarchaeological analysis of the data suggests the evidence from the Outer Hebrides is indicative of imported products of fur-bearing species, such as skins or ‘trophies’, the evidence from Orkney suggests populations of fur-bearing species may have been purposefully introduced by humans. This raises interesting questions regarding human perception and use of the different species in prehistoric North Atlantic Scotland.     

Prevalence rates of spondylolysis in British skeletal populations

As an activity‐related pathological lesion, spondylolysis and its prevalence rates are indicative of relative diachronic activity levels in different populations. In this paper we document the prevalence of spondylolytic defects in a series of time‐successive populations with special reference to the recording methods employed, and compare the findings with modern clinical studies. We identify epidemiological trends in expression of the condition through 1500 years in a series of skeletonised human remains from England. This includes a 5th–6th‐century settlement, a 15th‐century mass grave, a 14th to 17th‐century rural parish, a medieval Dominican friary, a medieval leper hospital and an 18th to 19th‐century crypt collection. These skeletal populations sample human groups experiencing considerable social change from an agrarian, non‐centralised early medieval period through the development of the medieval state to the earliest phases of industrialisation in England. A detailed study of all lumbar vertebrae in one of the assemblages highlights discrepancies between clinical prevalence rates for spondylolysis established through radiography, and those resulting from direct osteological analysis of the lumbar region of the vertebral column. Current prevalence rates cited in the osteological as well as the clinical literature are greatly dependent upon the recording methods employed, and the effects of several methods for osteological remains are considered in this treatment. For the populations reported on here, prevalence rates vary from considerably less than 1% to as much as 12%, depending on the method selected. A standardised recording method for spondylolytic lesions is suggested to facilitate accurate prevalence reporting and comparison of activity levels between different populations.

The Meul Index: A non‐destructive method for estimating the cortical index in skeletal samples

The study of osteoporosis in past populations provides insight into the history and evolution of this condition. The Cortical Index is a relative measure of cortical bone often used for identifying individuals with age‐related bone loss associated with osteoporosis. Current methods of measuring the Cortical Index involve radiography or cutting actual sections of long bones at the mid‐shaft. We propose a new index, the Meul Index as means for estimating the Cortical Index without the use of radiography. Based on a preliminary study of 13 individuals consisting of 9 males, 3 females and one unknown sex, ranging in age from young to older adult, the Meul Index is highly correlated with the Cortical Index (r = 0.903). The proposed Meul Index provides a non‐destructive and inexpensive means for studying age‐related bone loss in prehistoric and historic populations represented by skeletal samples. Our research builds on the recent publication of Silva, A.M., Crubezy, E. and Cunha, E. 2008. Bone weight: new reference values based on a modern Portuguese identified skeletal collection. Int. J. Osteoarchaeol. DOI: 10.1002/oa.998. Copyright © 2009 John Wiley & Sons, Ltd.     

A Geometric Morphometric Study of Regional Craniofacial Variation in Mexico

Spanish speaking populations in the USA have long been categorised under the umbrella term ‘Hispanic’, which is a cultural construct. The term Hispanic ignores the unique ethnohistories and biological variation among Hispanic groups with various European, African and indigenous American influences. Considerable heterogeneity has been identified in pre‐contact America and has continued to influence the cultural and biological compositions of various regions today. The purpose of this research is to examine biological variation in Mexico, which was influenced by indigenous migration patterns and the Old World conquests of the Americans. Using multivariate statistics, this paper compares 16 three‐dimensional craniometric landmarks of samples from northern Central Mexico, northern Yucatan and western Mexico to examine the regional biological variation present in Mexico in both prehistoric and historic groups and also compares Mexican, Spanish and African American groups to examine patterns of Old World conquests. Multivariate statistics detected significant group differences for both size and shape (centroid size, p < 0.0001; shape, p < 0.0001) and showed that while significantly different, all the Mexican groups are more similar to one another except for one prehistoric inland‐western Mexican group, which is morphologically distinct from the other Mexican groups. Previous mtDNA research in these areas shows a low prevalence of African American admixture and a high indigenous component in the northern Mexican groups, which is consistent with the findings of this paper. The prehistoric and historic Mexican groups were the most similar indicating the retention of indigenous admixture after contact. The results from this analysis demonstrate that all groups are significantly different from one another supporting other findings that have shown that the indigenous populations of the New World are heterogeneous and that this variation may also contribute to the heterogeneity of contemporary populations.

Sex inequality in the Māori population in the prehistoric,proto-historic and early historic Eras in a Trans-Polynesian context

This study considers evidence of Māori sex inequality in life chances during the prehistoric, proto-historic and early historic eras in terms of sex differences in bone size and structure, historic reports of sex dimorphism in height, and early census data of ratios of numbers of males to females. The triangulated evidence suggests significant inequality by sex. This evidence is then placed into a contact era Polynesian context. The broader evidence, also triangulated, suggests that sex inequality amongst Māori was not unique in Polynesia. Nor, however, was inequality universal across Polynesia. There are wide differences in sex inequality in different contact-era Polynesian societies. Sex inequality appears to have been less in Tonga, Samoa and Hawai’i than in New Zealand, Tahiti, the Marquesas, Easter Island and the Cook Islands. Sex inequality mostly collapsed by the first third of the 20th century, rendering the cross-island comparisons much more homogeneous.     

CARBON ISOTOPE RATIOS IN PALAEODIET: LACK OF AGE OR SEX EFFECT

Palaeodiet of humans can be determined using stable carbon isotope ratios of bone collagen. Differences in δ¹³C-values between individuals in a population may be due to real differences in diet, or alternatively, they could be due to age- or sex-dependent differences in the physiologically controlled fractionation of carbon isotopes between food and collagen. The dependence of this fractionation on age and sex was tested in a study of 50 individuals of differing ages from a prehistoric population of bison hunters. The total variation in δ¹³C for bone collagen was found to be ± 0.3‰, indicating that variations larger than this, observed in other populations, are due to real dietary differences between individuals.     

Tooth wear in two ancient populations of the Khazar Kaganat region in the Ukraine

Tooth wear is a common phenomenon in archaeological material. It has been related to the abrasiveness of diet and to the tribological attrition of teeth of individuals. Numerous investigations have been carried out in north and middle American samples as well as African anthropological material. Not much is known about tooth wear in European cultures. Eleven skulls from Chervona Gusarovka, and 14 skulls from the Upper Saltov sites of the Khazar Kaganat region (8th–10th centuries AD) in eastern Ukraine, with different diets were examined. A total of 208 teeth were studied for tooth wear, caries prevalence and periodontal status. Abrasion grades were determined according to a standardised classification and statistically evaluated. Periodontal status was measured using the distance between the enamel‐cementum junction and alveolar crest and the gingival attachment level respectively. Tooth wear was significantly different (P < 0.01) between the two populations. A low caries prevalence of 4.2% in the Chervona Gusarovka population and 1.7% in the Upper Saltov population was found. Significantly more alveolar crest bone resorption on the lingual side was found in the premolars and anterior teeth of the Chervona Gusarovka population. No significant differences were found regarding gingival attachment levels and gingival recession. It is concluded that the content and mode of food preparation influenced tooth wear, as reflected by the prevalence of dental caries and periodontal diseases in these ancient populations.

Evidence of Social Stratification in Bronze Age Denmark

Abstract

The Late Bronze Age hoards (12th–6th centuries B.C.) from Denmark are examined as evidence of the existence of social ranking in that prehistoric society. The hoards contain bronze weapons and ornaments which seem to function as sumptuary goods and appear to be ranked according to regular rules. The hoards also represent economic wealth and include objects of ritual importance. This intersection, in single finds, of material reflections of the political, religious, and economic systems in the society, along with the inferred existence of social ranking, suggests the presence of a prehistoric chiefdom in Denmark in the Late Bronze Age.     

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.

Age at death estimates for the protohistoric Arikara using molar attrition rates: A new quantification method

Dental attrition is positively related to ageing and has often been used to determine age at death of animals and prehistoric/historic humans. A newly designed molar-attrition-scoring standard was applied to a protohistoric skeletal sample, the Arikara (N = 143) from the North American Plains. Several criteria are used in producing a molar tooth crown wear (MTCW) score. These include: (i) the size of enamel wear facets, (ii) the amount of dentine and secondary dentine exposure, (iii) the height of the tooth, (iv) the enamel rim thickness, and (v) the amount of pulp-cavity exposure in the advanced stages. Age-at-death estimates were generated from ordinary least-squares (OLS) analysis, with estimated age regressed independently on the total molar attrition score (TMAS), mean molar-1 tooth crown wear (ȲM1TCW), mean molar-2 tooth crown wear (ȲM2TCW), and mean molar-3 tooth crown wear (ȲM3TCW). In all analyses (with the exception of the third molar), the coefficient of determination (r²) revealed a strong relationship between molar attrition and age. Multiple-regression analysis revealed a significant sex difference in molar-attrition rates. Besides intercept and slope differences, the female scatter showed greater molar attrition variation than the male scatter. There was no statistical difference between mean upper molar attrition score (UMAS) and lower molar attrition score (LMAS). There was no significant difference in molar attrition rates by side, and side by molar tooth.     

Estimating the Age and Sex of Caribou from Mandibular Measurements

Formulae for estimating the age and sex of caribou are derived from measurements taken from a control sample of caribou mandibles collected by the Canadian Wildlife Service. A robust linear relationship was found to exist between first molar crown height and age, while male and female mandibular measurements are statistically distinguishable on either side of a linear regression line. The application of these formulae to three 19th century archaeological assemblages from the western Canadian Arctic indicates their usefulness in estimating the age and sex of fossil populations, although some problems due to geographical variability remain. Tentative results indicate that traditional western Arctic Inuit were unable to exert strong control over the age and sex of the caribou they killed, perhaps because of the use of large-scale communal hunting techniques. This situation seems to have changed radically with the introduction of firearms in the 1870s.     

Did Children in Medieval and Post‐medieval Poland Suffer from Scurvy? Examination of the Skeletal Evidence

Late‐medieval and post‐medieval writings report that scurvy was a widespread condition in medieval and early historical Poland. Archaeological and historical data indicate that the diet of children was based on foods poor in vitamin C and contained small amounts of raw plant products. Also, historians emphasise that in medieval and post‐medieval Poland, there were seasonal fluctuations in food availability, frequently accompanied by poor harvests. Both resulted in long periods of poor nutrition, which affected children most severely. The aim of this study was to investigate skeletal manifestations of scurvy in subadult remains from medieval and post‐medieval Poland. Following standards described by Ortner and colleagues, anatomical sites pathognomonic of scurvy in subadults (<17 years) were assessed for abnormal porosity and hypertrophic bone among skeletons excavated from three sites: Ostrów Lednicki (dated to the 11th–14th centuries AD), Cedynia (10th–14th centuries AD) and Słaboszewo (14th–17th centuries AD). In total, 3.6% of all examined children were found to bear traces of vitamin C deficiency. The prevalence of scorbutic lesions was 4.5% for Cedynia, 2.6% for Ostrów Lednicki and 3.6% for Słaboszewo. The majority of affected children were less than 7 years of age. Scurvy was likely more widespread in the living populations than it appears from the calculation of skeletal markers, because some individuals might have recovered or died before obvious traces became apparent. Also, in some children, scurvy might not have reached an advanced stage, identifiable in the skeletal material. The prevalence of scurvy reflects not only dietary patterns but also food storage and preparation techniques adopted in the Polish territories during the Middle Ages, which contributed to low intakes of vitamin C.

Trepanation in Italy: A Review

This paper reviews and discusses cases of skull trepanation in ancient Italy on the basis of information provided by the literature. A total of 54 individuals from 43 different Italian archaeological sites were found to have evidence of trepanation. The analysis of evidences of trepanation in Italy has demonstrated that no differences can generally be perceived between the trepanned individual and the social context of the burial, leading to exclude a special role of the former within the group. Trepanation in Italy covers a time span of approximately 7000 years, the most ancient cases dating back to the fifth millennium bc and the most recent to the 18th–19th centuries ad . The geographic distribution appears quite homogeneous, with a prevalence of cases in Central Italy and abundant evidence from prehistoric Sardinia. The majority of individuals show a single trepanation, whereas others present skulls with multiple holes. Trepanation in Italy was reserved to adult individuals, except for some rare cases, and shows a relevant preponderance for the male sex. The most diffused technique is scraping; cutting and drilling are less attested, especially as unique techniques for trepanation, but they were used more frequently in combination with scraping. Trepanation could in some cases be hypothesised as therapeutic intervention for the treatment of a traumatic wound or of other pathologies, whereas in other cases, a number of evidences are attested of trepanation performed as probable ritual intervention or as experimental surgery; in the remaining cases, the reasons for trepanation are unclear or not determinable. A high percentage of long‐term healing associated with trepanation has been evidenced. Copyright © 2017 John Wiley & Sons, Ltd.     

Palaeopathological and palaeogenetic study of 13 cases of developmental dysplasia of the hip with dislocation in a historical population from southern France

Dislocation of the hip can be consecutive to developmental dysplasia of the hip that is linked to a complex set of genetic and mechanical factors. The purpose of this report is to describe 13 cases of complete dysplastic hip dislocation observed in the skeletal remains of nine women exhumed from an historical gravesite dating from the 5th to 17th centuries in southern France. Despite the size of this palaeopathological series, which is the largest study published to date, findings indicate that the prevalence of hip dislocation in this historical sample was still lower than in some French areas at the beginning of the 20th century. Mitochondrial DNA sequencing demonstrated possible kinship only between two women, i.e. one who died in the period from the 11th to 13th centuries and another who died in the period from the 16th to 17th centuries. It is suggested that the tight swaddling of young infants in France up to the end of the 19th century could have been a predisposing factor for this highly debilitating disorder.

On Colouring Statues

Auldhill, on the Ayrshire coast of the Firth of Clyde, is a site with a very long history. Excavations were conducted there for a total of ten weeks in 1987, 1988 and 1989, and seven main phases were recognized, as follows: I the timber-framed fort occupied in the first millennium B.c.;

II the iron age or early historic dun;

III the timber castle of the twelfth-thirteenth centuries;

IV the stone castle of the late thirteenth century;

V the hall of the end of the thirteenth or early fourteenth century;

VI the remodelled hall; and

VII dismantlement and stone robbing of the site from the mid-fourteenth century. Significant finds from the prehistoric deposits include an antler cheek piece and cannel coal jewellery. The main objective of the excavations was to understand the use of the site as a lordly residence in the medieval period. An architectural analysis is offered of Portencross Castle, the fourteenth-century successor of Auldhill in an appendix.

     

Past or present? Differentiating California prehistoric native American remains from forensic cases: An empirical approach

The goal of this project is to provide additional data and statistical analyses for differentiating between prehistoric/historic Native American remains and modern forensic cases that may be potentially confusing. Forensic anthropologists often receive requests from local law enforcement to infer whether skeletal remains are of forensic or non‐forensic significance. Skeletal remains of non‐forensic significance are commonly of Native American ancestry, but the empirical methods common for determining Native American affinity from skeletal remains have not been established for California prehistoric/historic Native Americans. Therefore, forensic anthropologists working in California lack empirical methods for not only identifying prehistoric California Native American remains, but also differentiating them from modern/forensic populations whose skeletal attributes are similar. In particular, skeletal remains of Latin American US immigrants of indigenous origins are becoming more present in the forensic anthropological laboratory, and can exhibit the same suite of skeletal traits classically used to identify Native American affinity. In this article, we initiate an investigation into this issue by analyzing both craniometric and morphoscopic data using a range of statistical methods for differentiating prehistoric Northern California Native Americans from modern Guatemalan Maya. Our discriminant analyses results indicate that by using nine craniometric variables, group classification is 87% correct. In addition, seven morphoscopic variables can predict group classification correctly for 77% of the sample. The results suggest that it is possible to differentiate between our two samples. Such a method contributes to the efficient and empirical determination of temporal and geographic affinity, allowing for the repartriation of Native American remains to their tribes, as well as the accurate analysis of forensically significant remains.
