Reconstructing age distribution,season of capture and growth rate of fish from archaeological sites based on otoliths and vertebrae

The growth increments of otoliths and vertebrae of plaice (Pleuronectes platessa) derived from a 15th century single depositional event at Raversijde (Belgium) are analysed with the aim of reconstructing (a) the age distribution of the population, (b) the season of capture, and (c) the growth rate. Otoliths and vertebrae give slightly different age distributions but it is possible to arrive at similar seasonality estimations in both structures when information from the literature and our own data from monthly captures of plaice from the North Sea are taken into account. These modern data show that the timing of annulus formation in otoliths and vertebrae is more or less similar. Back‐calculations on vertebrae and otoliths yield similar growth curves. The age distribution, the edge condition of both vertebrae and otoliths, and the growth rate obtained on the material from Raversijde all show that the plaice from the studied assemblage were captured during spring in the southern part of the North Sea. Vertebrae are commonly preserved in archaeological sites whereas otoliths rarely survive. Although they are more difficult to read than otoliths, vertebrae of plaice can be used for growth increment analyses, and the growth rates obtained from vertebrae from archaeological sites can, therefore, be compared in the future to growth data from modern otoliths studied in sea fisheries research. Archaeozoological material predating industrialized fishing since the 19th century can hence serve as a reference in the study of the compensatory response of commercially important species to heavy exploitation.

A recently excavated odontome from medieval Canterbury,Kent

During archaeological excavation of St George's church, Canterbury, 269 skeletons ranging from early medieval to late nineteenth century were recovered. A medieval female aged ca. 23–28 years displayed an unusual dental anomaly, an odontome. Odontomes are infrequent in clinical dentistry. A search of the literature suggests that very few archaeological examples have been published and our specimen is the first excavated case reported from Britain. Archaeological material, if subject to radiographic examination, provides a unique source of information for the prevalence of odontomes from prehistoric to modern times.     

Excavating Utopia: Why Archaeologists Should Study “Ideal” Communities of the Nineteenth Century

The study of utopias is riddled with contradictions: we admire and fear them; they are a radical critique of the modernist societies that surround them, and yet they are in some ways the archetypal product of modernity. This paper suggests that studying Utopia could be of value in analyzing some of the complexities and contradictions of Western society and ideology in the nineteenth century, as well as causing us to question some of the preconceptions we regularly bring to the study of the archaeological past. Finally I will suggest that a different kind of nineteenth century, one which includes the radical dissent and resistance of utopian thinkers and experimenters, provides a strong basis for a critique of the social values of modern capitalism.     

Osteometric Analysis of South American Sea Lions (Otaria flavescens) Pups From Patagonia. An Assessment of Their Use as Indicators for Seasonality in Archaeological Sites

Zooarchaeological analyses of pinniped remains have been scarce in South America because of lack of specific studies of species determination and estimation of age and sex. Nonetheless, the presence of small and unfused bones (assigned as pup remains) of Otaria flavescens (O. flavescens) in the Patagonian archaeological record has been frequently used as an indicator of summer occupation accomplished by ecological analogues. For this reason, we carried out a postcranial skeletons osteometric study of modern pups of South American sea lions (O. flavescens) with known sex and aged 0–12 months, allowing a more precise age estimation of archaeological samples. Then, we revisited the evidence for seasonality in the Cabo Virgenes 6 site at Cabo Virgenes locality, one of the archaeological localities in Patagonia where the seasonality has been determined only on the basis of the presence of unfused pup bones. Our metric data study on a modern sample shows that the regression analyses generated a complementary and dependable age estimation model for unfused appendicular bones of O. flavescens between 0 and 12 months old that can be applied to samples recovered from archaeological sites. These osteometric studies of postcranial elements allow us to adjust the age estimation of the animal's death and re‐examine seasonality of the Cabo Virgenes 6 site (Santa Cruz, Argentina).

Universal methodology for developing univariate sample-specific sex determination methods: an example using the epicondylar breadth of the humerus

In this paper we present a new methodology for developing sample-specific metric sex determination methods using unidentified individuals that can be applied to archaeological samples. This methodology does not require the assessment of sex of a large sample from pelvic morphological features as a first step in developing the method and instead is developed from a sample of individuals with sex unknown. The procedure involves using the overall mean of a measurement collected from the sample of unknowns as the discriminant criteria for determining the sex of the individuals in that same sample. Experiments with various sample sizes and sex ratios using distal humerus measurements from the Coimbra Collection (Portugal) suggest that allocation accuracies of 83–96% can be expected when the sample used to develop the method is greater than 40 individuals and the sex ratio is less than 1.5:1. The utility of the methodology is explored using the Lisbon Collection (Portugal) and an archaeological sample from Belleville (Canada) is tested as an example. The Lisbon Collection data indicate that joint measurements of long bones will provide the highest allocation accuracies. The results from the Belleville sample confirm that humerus joint measurements consistently provide the highest allocation accuracies (88–100%) even when the sex ratio in the sample used to develop the method is estimated at 1.9:1.     

The Modified Triangular Graph: A Refined Method for Comparing Mortality Profiles in Archaeological Samples

Plotting the percentages of juvenile, prime, and old individuals on a triangular graph has become a popular method for analysing mortality profiles or age structures found in archaeological faunal samples. This method allows easy comparisons of multiple samples or multiple species and appears to work even with small sample sizes. However, the utility of triangular graphs is compromised for two reasons: (1) samples cannot be statistically compared and (2) the points on the graph are based on percentages, and, therefore, they do not provide information about sample size. The modified triangular graph described here offers a method for approximating 95% confidence intervals around the data points by using bootstrapping. Samples with non-overlapping contours are likely to have had different pre- or post-depositional histories. The 95% density contours reflect sample size since they shrink as samples get larger. Thus, the modified triangular graph allows more confident comparisons of three age class data.     

The appearance and disappearance of Birket El-Kamar,Jaffa, Israel

ABSTRACT

The harbor of Jaffa is one of the oldest in the land of Israel and was a significant entry from the sea for the last 4000 years, from the Middle Bronze Age to the twentieth century. Birket el-Kamar was a sandy bay in the coastal strip south of modern Jaffa harbor that had been part of the harbor during various past periods, but no longer exists. Its name, meaning ‘the Moon Pool’, occurs in historical archival documents, mainly maps, from the nineteenth century to the first half of the twentieth century. This study focuses on the changing outlines of Birket el-Kamar during the last 800 years, based on recently revealed archaeological remains, and documentary evidence. It seems that in addition to the natural processes, the Ottoman fortress that was built on the natural sand strip connecting the rocks in the sea with the coast, also affected the on-going processes, through which the inner port, the central port and the north anchorage suffered higher erosion rates and the shoreline retreated eastward.     

Comparing methods for analysing mortality profiles in zooarchaeological and palaeontological samples

In this study, I examine three methods that are currently used for comparing mortality profiles from zooarchaeological and palaeontological samples: (1) histograms with 10% of life‐span age classes; (2) boxplots showing tooth crown height medians; and (3) triangular plots of the proportions of young, prime and old animals. I assess the advantages and disadvantages of each method using data collected on two samples of Northern Yellowstone elk (Cervus elaphus nelsoni) with known, or cementum annuli‐determined, ages at death. One sample was hunted by wolves (n = 96), and the other was hunted by recent humans using rifles (n = 226). I tested each method with the known or cementum annuli age distributions and with age estimation techniques appropriate for archaeological assemblages. Histograms are best used when the relationship between dental eruption/attrition and age is well established so that individuals can be confidently assigned into 10% of life‐span groups, and when more than 30 or 40 individuals are present in the assemblage. Boxplots employ raw crown heights, thus removing the error introduced by assigning specimens to age classes, and therefore they allow the analysis of species where the relationship between dental eruption/attrition and age is unknown. Confidence intervals around the medians allow samples to be statistically compared. Triangular plots are easy to use and allow multiple samples and species to be considered simultaneously, but samples cannot be statistically compared. Modified triangular plots bootstrap samples to provide 95% confidence ellipses, allowing for statistical comparisons between samples. When possible, samples should be examined using multiple methods to increase confidence in the results. Copyright © 2005 John Wiley & Sons, Ltd.     

Archaeological and archaeomagnetic dating at a site from the ager Tarraconensis (Tarragona,Spain): El Vila-sec Roman pottery

A very accurate archaeological dating of a Roman site in NE Spain (El Vila-sec) was made based on the typology of pottery artifacts. Three different phases were identified with activity ranging from the mid-1st century BC to the early-3rd century AD. Analyses of bricks from kilns at El Vila-sec produced data on their stored archaeomagnetic vector. These data were compared with the secular variation curve for the Iberian Peninsula and the SCHA.DIF.3K regional archaeomagnetic model. Both, the reference curve and the model, produced probability distributions for the final period of use for two kilns from the second archaeological phase that were not used during the third phase. At a 95% confidence level, both time distributions cover a wide chronological range including the presumed archaeological age. Both the Iberian secular variation curve and the SCHA.DIF.3K regional model proved to be suitable models for dating the site, although on their own they do not produce a single unambiguous solution. This archaeomagnetic approach could also be applied to neighbouring archaeological sites that have an imprecise archaeological age.     

Imperial Expansion, Ethnic Change, and Ceramic Traditions in The Southern Chad Basin: A Terminal Nineteenth-Century Pottery Assemblage from Dikwa, Borno State, Nigeria

In the course of an archaeological project in the southern Chad Basin of Nigeria, excavations were conducted at several deeply stratified mound sites that date from the Late Neolithic to the Late Iron Age. As a way to complement the ceramic sequence obtained so far and to link it with today's pottery tradition, a small excavation was conducted at a site that dates to the turn of the nineteenth to the twentieth century A.D. A pottery assemblage was discovered that shows obvious links to today's tradition but notable breaks with those of the nineteenth century and earlier. This break in decoration style and technique is interpreted as an archaeologically visible expression of changing ethnic identity. This ethnic change and the associated spread of the ceramic tradition can be linked with the expansion of the sphere of power of the Kanem-Borno Empire into the area south of Lake Chad after the sixteenth century A.D.     

Consumer Strategy and Household Consumption in the Cripple Creek Mining District, Colorado, USA

The Cripple Creek Mining District of Colorado (USA) was billed as “the World’s Greatest Gold Camp” in the 1890s and was home to a multitude of men, women, and children who left behind a record of past consumer behavior. Examination of fourteen household archaeological assemblages provides insight into aspects of household consumption strategies and the negotiation of socioeconomic class relationships within the late nineteenth and early twentieth century mining communities in the American West. An analytical approach that combines the quantitative economic scaling of ceramics and faunal remains is used in combination with the qualitative analysis of entire assemblages to understand consumer strategies and the negotiation of class relationships between households in the district.     

Implications of age variation and sexual dimorphism in modern equids for Middle Pleistocene equid taxonomy

Interspecific variation in the equid lineage is limited when compared with other large mammal lineages, while a considerable amount of intraspecific ecomorphological variation occurs. This has led to considerable debate regarding the taxonomic status of palaeontological and archaeological equid remains. The possible confounding impact of sex and age variation on analyses of archaeological equid remains has so far remained untested. This could be especially problematic when it is unknown whether an assemblage contains more than one equid species, breed or hybrid. Here, sex and age variation in modern equid species is examined and compared to variation in Pleistocene equid assemblages from northwest Europe. Sex variation in the longbones of modern equid species was found to be lower than variation over time. Similarly, age variation in dental elements of the same species is predominantly lower than diachronic variation, although caution needs to be taken when an archaeological assemblages consists mostly of elements at a similar wear stage. To assess whether late Middle Pleistocene caballoid horse fossils should be assigned to multiple species or be considered to form a monospecific group, the coefficients of variation for measurements on fossil horse remains were compared with those for modern equid specimens. Results indicate that the fossil assemblages are similarly variable to samples of modern material. Taken as a whole, the late Middle Pleistocene caballoid horse lineage is equally variable to an assemblage of modern ponies of a variety of different breeds. This implies that the variation observed between samples dating from different parts of the Middle Pleistocene can be characterised as intraspecific variation within a single species reflecting ecomorphological adaptations to the changeable Pleistocene climate.

The appropriation of the Phoenicians in British imperial ideology

The Phoenicians played ambivalent roles in Western historical imagination. One such role was as a valued predecessor and prototype for the industrial and maritime enterprise of nineteenth‐century imperial Britain. Explicit parallels were drawn in historical representations and more popular culture. It was widely believed that the Phoenicians had been present in Britain, especially in Cornwall, despite a lack of convincing historical evidence, and much importance was placed on supposed archaeological evidence. Ideological tensions arose from the need to reconcile ancient and modern Britain, and from the Semitic origin of the Phoenicians. This example shows the power of archaeological objects to provide material support for national and imperial constructions of the past.     

Application of non-adult Bayesian dental age assessment methods to skeletal remains: the Spitalfields collection

The aim of this study was to test with non-adult skeletons the quality of a recently published dental age assessment method based on Bayes' theorem. The test sample consisted of dental X-rays from 16 individuals (range 2.6–15.1 years) recovered from the crypt of Christ Church, Spitalfields, London, for which age-at-death and sex were known. The training sample consisted of dental X-rays from 1346 girls and 1040 boys (range 1.9–16.0 years). Bayesian dental age assessment method was alternatively used with dependent and independent assumptions; the dependent Bayesian method (DBM) and independent Bayesian method (IBM), respectively. Moreover, both DBM and IBM were used alternatively with sex-specific standards and with non-sex-specific standard. Due to the training sample age distribution, both methods are efficient between 5.0 and 14.0 years. Whatever the method or the sex standard used, when dental age was different from chronological age, the discrepancy did not exceed one age group of one year. DBM produced tighter dental age 100% confidence intervals than IBM for the majority of assessments. The observed stability between results produced according to the type of sex standard used (i.e. sex-specific or non-sex-specific), and the number of teeth studied (range 4–7), is worthy of note for both archaeological and forensic contexts.     

Photography and Latin American Ruins

Ever since the nineteenth century photographers have regularly turned to Latin American ruins to express a diverse range of scientific, colonial, aesthetic and spiritual desires. This article looks at photographs of Latin American ruins from the nineteenth century through several archaeological expeditions in Central and South America over the course of the twentieth century. Focusing in particular on photographs of ruins that include human subjects, I argue that the human-material interactions evident in these images undermine the traditional view of a split between the archaeological subject and the material object, serving as a reminder of the political actuality of ‘classical’ ruins, sites that have sometimes been left out of the West’s contemporary fascination with the dark underbelly of modernity. Acknowledging that such politics is by no means always innocent, sometimes reflecting as it does the embedded power relations of neo-colonial desires, I argue nonetheless that ancient ruins in Latin America continue to be spaces around which social relations can be formed, not least through humour and pleasure.     

Matchlocks, Flintlocks, and Saltpetre: The Chronological Implications for the Use of Matchlock Muskets among Ottoman-Period Bedouin in the Southern Levant

This paper examines the chronological implications for the prolonged use of matchlock muskets by the Bedouin during the Ottoman Period (1453–1918). Although the technology behind the matchlock ignition system is from the fifteenth century, this weapon was used by many Bedouin until the beginning of the twentieth century. As a result, the presence of gun parts from matchlock muskets poses a potential problem for identifying Bedouin occupations from the eighteenth and nineteenth centuries in the southern Levant and in northern Arabia. This issue is heightened by the paucity of diagnostic artifacts found at archaeological sites associated with the Bedouin during the Ottoman Period.     

Evaluating human skeletal growth: An Anglo-Saxon example

Cross-sectional growth data were obtained from the skeletal remains of non-adults from the Raunds Anglo-Saxon site. Standard measurements of the diaphyseal lengths of the long bones of the upper and lower limbs and the maximum breadth of the ilium were recorded in order to construct skeletal growth profiles (SGP). In addition regression equations were used to estimate diaphyseal length from proximal and distal shaft widths, and epiphyseal breadth data for fragmentary remains. The skeletal measurements were then plotted against age estimates determined by the dental formation standards of Moorrees, Fanning and Hunt, and Anderson, Thompson and Popovich. The growth data were compared with sixth to seventh century German, ninth century Slavic and modern Caucasian data. With the exception of the ancient Slavic material, the Anglo-Saxon remains demonstrated the smallest rates of growth. Diaphyseal ageing curves derived from the Anglo-Saxon sample were tested for applicability on the non-adult cohorts of the Berinsfield and Exeter Anglo-Saxon/Early Medieval samples. Differences were observed between diaphyseal age as determined from the skeletal growth profiles for Raunds and calcification age assessed for individuals within the test samples. It is proposed that variation in long bone growth as well as dental age confounds consistent and reliable ageing of skeletal remains based on diaphyseal length. Assessment of changes in health and evaluation of methodological problems inherent to studies of skeletal growth from archaeological populations are discussed. Population comparisons for changes in general health are recommended over individual assessments.     

Stratigraphic and spatial variability in shell middens: microfacies identification at the ethnohistoric site Tunel VII (Tierra del Fuego,Argentina)

Based on ethnographic accounts from the eighteenth to the twentieth century, functional areas have been identified within Fueginian shell middens. In this context, archaeological microfacies acquire a functional meaning when the microscopic record is compared to information gathered from ethnology, macroscopic observations made during excavation, and experimental modern analogues. All these lines of evidence were combined for the first time at Tunel VII, an eighteenth/nineteenth century shell midden occupied repeatedly by Yamana people, the last hunter–gatherer–fisher groups of the Beagle Channel. The sampling strategy involved three sets of samples: (1) two stratigraphical columns taken from the hut “entrance” and from a portion of the shell midden (i.e., the surrounding refuse shell ring), (2) thin sections from five hearths representing successive phases of frequentation of the hut, and (3) experimental burnt valves of Mytilus edulis, the main malacological component of the site. Comparison of microfacies from groups (1) and (2) provided microscopic indicators to distinguish between shell dumping areas and occupation surfaces. Comparison of microfacies within columns from group (1) allowed recognizing periods of site abandonment and periods of more intense/longer site frequentation. The experimental samples from M. edulis served as a reference to characterize the five central hearths in terms of maximum burning temperatures reached. Different burning structures were correlated to the season of hut frequentation and to their location (and function) within different portions of the hut. The intra-site micromorphological comparison strategy within a well-documented ethnohistorical context provides valuable indicators for the identification of functional areas in archaeological contexts when ethnographical information is not available.     

Myths of ancestry

This article examines the national significance of fifth‐century BC Greek sculpture and especially the so‐called Elgin Marbles. It examines the significance of these archaeological remains not for the Greek nation but for the British, and specifically the English, nation during the nineteenth century. The national significance of fifth‐century BC Greek art lies in its incorporation into nineteenth‐century debates concerning the identity of the English nation. At a time when physical appearance or race was accepted as an important and, indeed, determining component of the ‘self’ and a measure of collective belonging, Greek sculpture, which was primarily figural in its subject‐matter, came to be seen as an image of the English ‘self’. The belief in the Greek identity of the English caused a Greek revival in English life and art. In life, this revival took the form of care for the body and the imitation of the athletic practices of Greek youth through the practice of sport in English school and university education. It was thus that nineteenth‐century English youth turned itself into a work of art.
