The pattern of spondylosis deformans in prehistoric samples from west‐central New Mexico

A Pre‐Columbian skeletal sample (n=42) from two ancestral Pueblo sites in the Rio Grande valley of west‐central New Mexico was examined for frequency and severity of spondylosis deformans (vertebral osteophytosis). No significant sex differences were detected. Degenerative changes in the collective sample are generally confined to no more than well‐defined horizontal lipping at the joint margins. Advanced proliferative osteophytic change is infrequent even in the oldest age category. Not surprisingly, the lumbar vertebrae were the most frequently and most severely involved vertebral segment for all three adult age cohorts defined. The cervical vertebrae were the least involved. This pattern generally conforms with observations made on other archaeological samples from west of the Mississippi River, but it contrasts with the general pattern of more extensive cervical involvement in Pre‐Columbian North American samples from the Eastern Woodlands. This possible east–west difference is hypothesized (Bridges, P.S. 1994. American Journal of Physical Anthropology 93: 83–93) to be related to differential burden bearing habits.

Red marals at Satakular in the Alai

The article focuses on a newly discovered petroglyphic site on the Satakular River, Ongudai Region, Altai Republic. Rock art images were found in two areas on the walls of a natural groove running through a huge monolith rock. The images include several pecked representations and two unique red paintings of Siberian deer (marals). The images have parallels in the petroglyphs of the Minusinsk tradition in the middle reaches of the Yenisei River, the Afanasyevo culture at Kalbak-Tash Mount, and the Kuilu rock shelter. An analysis of Kalbak-Tash analogies suggests that the Satakular petroglyphs represent a pair of male and female maral deer. The painted images themselves demonstrate expressed artistic skill and the rock monolith with its unusual groove represents a unique site.     

Rock art on Socotra,Yemen: the discovery of a petroglyph site on the island's south coast.

Recent fieldwork on the south coast of the island of Socotra, Yemen, has revealed a hitherto unknown petroglyph site. This site represents the first rock art to have been recorded on the south coast, an area generally regarded as being unpopulated up until the recent past. The corpus of recorded petroglyphs includes feet, cupules, anthropomorphic figures and geometric motifs, whose designs parallel those from known rock‐art sites on the north coast. The importance of this site is that it provides us with the first glimpse into the religious and socio‐political lives of the inhabitants of the previously unknown southern half of Socotra. Placing these petroglyphs within the broader context of rock‐art studies on the island of Socotra has also allowed us to begin to disentangle the skewed view of Socotra's inhabitants.     

基于HSI彩色模型灰度分量的宁夏岩画断代研究初探

岩画是古代先民生产、生活、祭祀等活动的生动记载,是人类文明的史诗,岩画的断代一直是岩画研究的难点,文中提出了一种基于色度、饱和度和灰度(HSI)彩色模型的数字图像处理技术提取岩画灰度值(I)的方法,利用岩画灰度值与岩画作画年代之间的线性可比关系,测定岩画的年代。此方法能提取整个岩画中的灰度值,避免了手工提取有限个点的缺陷。试验结果表明此方法能为岩画的断代提供一种可参考的、简便的、快速的计算机解决方法,但测定年代的准确性依赖于选取的岩画标尺年代的准确性。     

Antillean Islander Space: On the Religious Beliefs and Representations of the Taíno People

This study aims to shed light on Taíno polytheism and its imprint in the Antillean geographic space and the unitary and differentiated development of its religious beliefs and representations, by means of mythic substitution and iconographic hybridisation, as a result of the multinatural perspectivism (animism) shared with its South American relatives and indigenous transculturation processes. It will also show the implications of a revised interpretation of the archaeological heritage based on a comparative approach using the available Caribbean ethnohistoric records (dated from the fifteenth century, mostly, like the mythological passages recorded by friar Ramón Pané) and contemporary lowland Amerindian ethnography along with the iconographic analysis of Taíno imagery in context, an area in which the pioneer linguist José Juan Arrom made the first advances, but his work now demands review.     

Lucayan–Taíno burials from Preacher's cave,Eleuthera, Bahamas

In March 2007, three prehistoric skeletons were excavated and analysed from Preacher's Cave on the northern aspect of the island of Eleuthera in the Bahama archipelago. The human skeletal remains represent two males and one female dating to AD 800–1300. The first is a female in the 30s with mild osteoarthritis of the joints and spine and several healed fractures who may have been an important community elder. The second is a male in the 20s with Schmorl's nodes who may have been a shaman or even a victim of interpersonal violence. The third is a male in the mid to late 20s also with marginal osteoarthritis of the joints and spine who may have been a ceremonial leader and village headman. The high incidence of carious lesions implies a cariogenic diet possibly rich in starchy foodstuffs or even fructose. The presence of grave goods and plaited mats suggest that at least two individuals may have been of high status. This study emphasises the significance of caves to Lucayan–Taíno mythology, cosmology and mortuary practice. Copyright © 2010 John Wiley & Sons, Ltd.     

A HYBRID APPROACH TO CREATE AN ARCHAEOLOGICAL VISUALIZATION SYSTEM FOR A PALAEOLITHIC CAVE

This paper presents a visualization system based on metric data to manage and disseminate archaeological information on the Internet. We describe the integration of two different types of sensors: laser scanning and close‐range photogrammetry. How we created an automatic and hierarchical approach based on processing and matching the images coming from a digital camera and a terrestrial laser scanner is also shown. This development has created a visualization system combining spherical photographs and georeferences for graphical and numerical data acquired by the sensors. The case study where we have applied this method is the Palaeolithic rock art of the Llonín Cave (Asturias, Spain), which has been declared a World Heritage Site by UNESCO and has restricted public access. Our results demonstrate that this tool integrates data, metadata, services and information, which simplifies the location, identification, selection and management of archaeological information.     

Treponemal Disease,Tuberculosis and Subsistence‐settlement Pattern in the Late Woodland Period West‐central Illinois

In later pre‐Columbian prehistory (post AD 1000), the adaptation and intensification of maize agriculture and its correlate of aggregate village settlement (i.e. Mississippianization) is temporally and geographically variable. In the Midwest, consequential to the florescence of the major ceremonial centre of Cahokia (AD 1050–1300), the Mississippi River Valley alluvial plain in Illinois, known as the American Bottom, became a core area of this subsistence‐settlement change. Much archaeological research has traced aspects of this transition in the Lower and Middle Illinois River Valley, but little is known outside of these areas. A skeletal sample from the remote hinterland area of the Upper Mississippi River in west‐central Illinois was examined for arguable paleopathological correlates of sedentism (treponemal disease) and Mississippianization (tuberculosis). The Schroeder Mounds (AD 900–1100) adult skeletal sample (N = 53) exhibited a high frequency of treponemal disease (13.2–15.1%). This result is consistent with paleopathological literature linking a 9+ % pre‐Columbian North American prevalence with sedentism, challenging archaeologically based inferences that the hinterland was occupied by mobile forager‐horticulturalists. A hallmark of Mississippianization is the presence of diagnostic cases of tuberculosis. No cases were observed in the Schroeder sample, suggesting a pre‐Mississippian subsistence‐settlement pattern.

Metallic encounters in Cuba: The technology,exchange and meaning of metals before and after Columbus

Metals held important symbolic and political values for the indigenous communities of the Caribbean islands. However, metal objects are not abundant in indigenous archaeological sites, and their study has hitherto been very limited. This paper presents the results of the first analytical programme focused on metal artifacts recovered in a range of Taíno sites in Cuba, chronologically covering the periods before and after contact with Europeans. Our aims were: (a) to identify metallurgical traditions related to a diversity of cultural or learning backgrounds; (b) to investigate the origins of different metal artifacts found in Cuba, as a proxy to reconstruct patterns of exchange and interaction among indigenous communities and between these and Europeans; and (c) to approach the meaning and symbolism of different metals by considering their contexts of appropriation and use. The techniques employed included optical microscopy, SEM–EDS, pXRF and PIXE. The results allow a diachronic picture of the procurement, transformation, use and symbolism of metals in Cuba with broader implications for Caribbean archaeology. We reveal culture-specific Taíno choices in their interaction with materials and value systems from continental America and Europe. We also discuss the selective appropriation, recontextualization and meaning of different metals in the indigenous cultures.     

Rock art survey in the ancient oasis of Salūt (northern Sultanate of Oman): a variegated iconographic record

The systematic survey of petroglyphs in the area of the ancient oasis of Salūt, in central Oman, highlighted a rich repertoire of representations that are here discussed against the background of Arabian rock art in general. The region displays an extremely rich number of engravings along the slopes of the Jabal Hammah, north of the main site of Salūt. The majority of the petroglyphs find abundant fitting comparisons in the region. The notable exception of the motif of the “man with halberd” is presented, as it appears to be significantly rare and underlines interpretative issues concerning the so-called T-shaped signs, ubiquitous in Arabian rock art. One of its occurrences was radiocarbon dated to before the mid-first millennium BCE. This and other, relative hints for reconstructing the chronological context of the petroglyphs are discussed, indicating that engravings can be broadly dated from the second millennium BCE onwards.

Working on Rock Art in the Dakhleh Oasis: Some Thoughts on Threats to Petroglyphs and Possibilities of Research in the Western Desert,Egypt

The rock art in Dakhleh, despite being known for more than a century, has been thoroughly investigated only since the late 1980s, and remains far from being well known especially outside of Egypt. At the same time, the consecutive seasons of fieldwork conducted by the Petroglylph Unit (part of the international Dakhleh Oasis Project) have produced a great number of findings and substantially enhanced our knowledge of the petroglyphs of this area. Here, rather than focusing on interpretive aspects of the research, I wish to discuss the threats endangering the petroglyphs in the Oasis. Dakhleh has developed very intensively in the last 100 years. It is, however, the twenty-first century which seems to pose some serious threats to archaeological heritage. Hence, in this paper I wish to report on what has been done so far to document rock art in the Oasis, and try to establish the priorities for potential future work. The agricultural and infrastructural development in the area, and the uncertain political climate in the country, heavily influence the state of rock art preservation and the possibilities of research. The need for documentation and preservation of rock art is larger than ever before, because many changes in the local landscape cannot be stopped. The time is pressing, because more and more rock art is disappearing due to the reasons discussed in this paper. Threats to Egyptian rock art in general will form a background for considerations concerning petroglyphs from the Western Desert.     

Three-dimensional recording by laser scanning of the petroglyphs at Rombald's Moor,West Yorkshire

Abstract

A variety of methods have been used to depict and document petroglyphs, from hand sketching to close-range photogrammetry. Most methods, however, record only a two-dimensional image, whereas petroglyphs are by their nature three-dimensional. Additionally, most methods suffer from inaccuracies resulting from the skill and subjectivity of the recorder or distortions imposed by the equipment and conditions under which the panel was viewed. Conventional three-dimensional recording techniques such as the use of traditional moulding and casting materials, may damage the petroglyph itself. An assessment of the various shortcomings of established rock art recording methods resulted in the field-testing of laser scanning with the objective of obtaining a quantitative, three-dimensional record of petroglyph panels and the creation of non-contact replicas. This paper presents the principles behind laser scanning and an account of field trial results of laser scanning rock art in situ at Rombald's Moor, West Yorkshire, England. The work presented was undertaken as part of the Rock Art Pilot Project commissioned by English Heritage in July 1999.     

CONSTRUCTING CARIBBEAN CHRONOLOGIES: COMPARATIVE RADIOCARBON DATING OF SHELL AND WOOD ARTEFACTS FROM PRE‐COLUMBIAN SITES IN CUBA

The lack of robust chronological frameworks for pre‐Columbian archaeology in the Caribbean limits the interpretive potential of ongoing studies of inter‐site and inter‐island interaction. This paper reviews the dating of 28 wood and shell artefacts from sites in northern Cuba in an attempt to date pre‐Columbian activity in the region and develop dating methodologies for the study of pre‐Columbian interaction in the Caribbean. This research compares dates from wood and shell artefacts from the waterlogged site of Los Buchillones in north‐central Cuba with dates from shell artefacts from sites on eight islands in the Sabana–Camaguey archipelago in the Bahama Channel. In addition to providing a chronological framework based on absolute dates for pre‐Columbian activity in northern Cuba, this paper also considers the methodological issues of using shell for dating pre‐Columbian activity in the Caribbean.     

Morphometric analysis and detection of invisible archaeological elements by spectral treatment of digital images

The aim of this paper is to describe the creation of a method to apply digital image treatment, consisting of a combination of filters and algorhythms, to prehistoric rock carvings, to enhance the information obtained from them. In the experimental phase a study was made of a laboratory piece and two highly valuable pieces of cave art from the Tamanart Valley in Morocco and the Casares Cave in Guadalajara, Spain. The results clearly demonstrate the potential of the proposed digital methodas information was obtained that could not have been achieved by the traditional techniques.     

The economic development of West Africa

Almost all documented landslides in Scotland belong to one of four categories: non‐rotational rock slope failures (major rockfalls, translational slides, topples or sags, often in some combination); rotational rock slope failures; debris flows; and translational slides in drift or regolith. Non‐rotational rock slope failures are particularly common on Highland metamorphic rocks, especially schists, and on igneous scarps in the Hebrides and Midland Valley; rotational rock slope failures almost invariably occur in weak sedimentary rocks overlain by resistant igneous rocks; and debris flows are most common on sandy drift or regolith. Former glacial activity has also been of importance in determining landslide distribution. The great majority of rock slope failures are ancient features, but debris flows and small translational slides in drift (both triggered mainly by intensive rainstorms) are much more frequent at present and cause much greater damage, particularly to communications.
