Introducing δSr analysis in archaeology: a demonstration of the utility of strontium isotope fractionation in paleodietary studies

Isotopic methods are widely used in archaeology to investigate paleodiet. Here, we present a new method to identify trophic level in archaeological human populations and to investigate paleodiet. We demonstrate that strontium isotope compositions (reported as δ^88/86Sr) vary in a mass-dependent manner with increasing trophic level and can elucidate paleodiet in archaeological human populations. We present new mass-dependent strontium isotope data from tooth enamel and bone from individuals buried during the Late Intermediate Period (c. AD 1000–1300) in the large cemeteries of Chiribaya Alta, Chiribaya Baja, San Gerónimo, and El Yaral in the Ilo and Moquegua Valleys of southern Peru. We compare these data to radiogenic strontium isotope data (⁸⁷Sr/⁸⁶Sr) and light stable isotope data (δ¹⁵N_col and δ¹³C_col) from the same individuals to investigate geologic variability in strontium sources as well as marine food consumption among the Chiribaya. Our results demonstrate the utility of measurements of strontium isotope fractionation as a new tool for archaeological investigation of paleodiet. Importantly, this new technique can be used to generate paleodietary (δ^88/86Sr) and paleomobility (⁸⁷Sr/⁸⁶Sr) data from the same specimen, minimizing destructive analyses of invaluable archaeological material, and provides a new way to examine paleodiet through hydroxyapatite, which is particularly important when collagen is poorly preserved.     

Variations in the bridging trait of the hypoglossal canal in 13th century Byzantine skulls

The presence of a bony bridge in the (bridging trait) hypoglossal canal, with five different modes, was investigated in 25 adult male Byzantine (13th century) skulls. First, we re‐evaluated the viability of proposed classification schemes, then for the first time, provided information on the structural features of this part of the occipital bone in a population of Asia Minor. Analysis of the data revealed minor differences in the Byzantine population compared to those previously investigated. Diverse geographical sources may be beneficial in understanding the role of developmental and genetic factors in bridging trait. Copyright © 2005 John Wiley & Sons, Ltd.     

Dendrochronological dating of wooden artifacts by measuring the tree rings using magnifying glass and photography-assisted method: an example of a Dutch panel painting

Dendrochronology, an analysis of tree rings, is a commonly used method for dating wooden structures in archaeological remains and historical objects. Fascinating subjects of examination are the historical oil paintings on oak panels. Here, we applied a tree ring analysis on three boards of a Dutch painting from the Sinebrychoff Art Museum (Helsinki). Tree rings were measured using the conventional lens-assisted method, in addition to the photography-based approach, where the widths of the rings were determined from digital enlargements of the photos. These two methods produced comparable tree ring series. The lens- and photography-based records of the measured panel exhibited higher agreement with each other than the conventional, lens-based, record against the different master chronologies. Dendrochronological cross-dating against the master chronology showed that the rings of the panel represent the period ad 1413–1620. Cross-dating was attained by comparing the tree ring series of the panel painting with the previously published chronologies obtained from timber transported from the historical ports of the Eastern Baltic Sea to Western Europe. Photography appears as a promising method to be used for dendrochronological investigations of archaeological and historical objects, alongside the conventional methods. We note that the importance of using photographs of tree ring cross sections was highlighted already in the 1930s. In the digital era, the photographic approach shows obvious benefits for archival purposes and remeasuring the rings, with additional future prospects of image processing and analyses.     

Pottery Production in the Buddhist Communities in Central Asia: The Kushan‐Sassanian Pottery Workshop of Kara Tepe (Termez,Uzbekistan)

We present the first full archaeometrical study of Kushan‐Sassanian pottery from the Buddhist monastic complexes at Kara Tepe (Termez, Uzbekistan), recovered both in the pottery workshop and in the monastery, using a combination of analytical methods (XRF, XRD, SEM–EDS and OM). The study allowed the identification of the reference group, the correspondent fabric, the raw materials used for its productions, some of the technological processes involved in manufacture and several weathering processes. All the results confirm that the kiln was supplying the religious community of the monastery with pottery, made using local raw materials, and highlight the possibility that the kiln could have supplied the nearby monastic complexes, where no kilns have been found. Further archaeological evidence indicates the existence of specialized potters working itinerantly at the broader Bactrian area.     

The Muddle in the Middle Pleistocene: The Lower–Middle Paleolithic Transition from the Levantine Perspective

The terms Lower Palaeolithic and Middle Palaeolithic represent research constructs within which cultural evolution and prehistoric hominin behaviours can be studied, with the transition usually understood as marking a watershed in our evolution: an adaptation with a million-year record of success that gives way to something new. The interpretation of the Lower Palaeolithic Acheulian technocomplex is usually understood as a period of cultural stasis that extends over much of Africa and Eurasia, principally associated with Homo erectus. Those innovations that can be observed occur widely separated from one another in space and time. Yet a closer and more detailed examination of the Middle Pleistocene records from East Africa, southern Africa, Europe and the Levant reveals significant variation in cultural repertoires. A kind of paradox emerges, in which an Old World Lower Palaeolithic, apparently lacking an overall dynamic of distinctive and directed change in terms of cumulative variation over time, nevertheless culminates in a transition which sees the universal appearance of the Middle Palaeolithic. The two main hypotheses that have been advanced to explain the global transition, which happens essentially synchronously, appear mutually exclusive and contradictory. One view is that altered climatic-environmental constraints enabled and encouraged an ‘Out-of-Africa’ dispersal (or dispersals) of a new type of genus Homo. This cultural replacement model has been challenged more recently by the alternative hypothesis of accumulating but unrelated and temporally non-linked regional, and in fact potentially autochthonous, processes. The Levant, by virtue of its position bridging Africa and Eurasia (thus being the region into which any out-of-Africa groups would have had first to disperse into), must be seen as a critical region for assessing the relative merits of these competing hypotheses. This paper deals with the Lower–Middle Paleolithic boundary in the Levant within a long temporal perspective. The Middle Pleistocene record in the Levant enables us to examine the amplitude of variation within each techno-complex, as well as to question whether there are diachronic changes in the amplitude of techno-typological variations as well as changes in the manner by which they appear in the record. The results carry significant implications for understandings of demographic and societal processes during the Lower–Middle Paleolithic transition in the Levant.     

The Shadow Field of Reindeer Management: A Case Study from Finland

Abstract

This article applies the analytical concept of shadow field in relation to reindeer management, to explain why some herders and reindeer herding cooperatives do not adhere to government regulations on herd size. The underlying processes and structures related to reindeer numbers are exemplified through two case studies of two Finnish reindeer herding cooperatives, which for several years have exceeded the total allowable quota of reindeer. The case studies reveal a different reality of reindeer management, which functions according to a logic and agenda not always understood by the State authorities or incorporated into the management decisions. This reality is the outcome of anomalies in the official reindeer management system, including the system's disclosure of herders from the decision-making process, the system's provision of self-determination and self-monitoring regarding the organisation of reindeer herding to the cooperatives, the system's weak external control and a subsidy system which promotes reindeer ownership instead of production. Combined, these anomalies enable and encourage the formation of a shadow field of reindeer management. This paper uses as its theoretical framework Pierre Bourdieu's theory of practice, and focuses especially on the key notion of field and shadow field in addressing the Common Pool Resource discussion related to reindeer herding.     

Laser scanning for conservation and research of African cultural heritage sites: the case study of Wonderwerk Cave,South Africa

The ‘African Cultural Heritage and Landscape Database’ project, initiated and directed by the senior author and administered by Aluka (www.aluka.org), is aimed at the creation of a digital library of spatial and non-spatial materials relating to cultural heritage sites in Africa. The archaeological site of Wonderwerk Cave (South Africa) is one of the 19 sites documented to date using laser scanning, conventional survey, digital photogrammetry and 3D modelling. To date, it is one of the few archaeological caves worldwide to be fully scanned. This paper explores the different uses to which the spatial data derived from this cave have been, or will be, put – for historical and educational purposes, scientific research and site conservation and development.
