Recent carbon isotope research and its implications for African archaeology

A number of new developments in the carbon isotope field are reviewed, some of these having immediate and others potential application to African archaeology. Mass spectrometric analysis of¹³C/¹²C ratios in human and animal bone collagen makes it possible to reconstruct prehistoric foodwebs and to draw conclusions about dietary adaptations. Alternatively, where dietary behaviour is known, analysis of the bone of certain animal species allows for reconstruction of past environments. Ratio mass spectrometers are widely available in research institutions, and provided that the proper techniques for sample preparation are followed, this method of analysis should be of immediate use to most Africanists. It is already making an impact on African archaeology. The development of accelerator-based or high energy mass spectrometry (HEMS) radiocarbon dating provides the potential for extending the method back to 100,000 years, particularly in the case of bone samples. Practical applications, however, are still a few years off. In the immediate future HEMS dating is likely to be applied to small samples of ages less than 50,000 years. In competition with HEMS is the use of mini-counters for conventional radiocarbon dating of small samples. This procedure is available in a few laboratories with more under development. Dating of small samples has potential applications in many areas, specifically in the direct age measurement of critical specimens as opposed to the dating of associated materials.     

Another Dating Revolution for Prehistoric Archaeology?

Transitions to the Howiesons Poort Industry and other early modern human cultural phases have conventionally been explained as direct or indirect responses to major climatic and ecological fluctuations. Advances in optically stimulated luminescence dating have now provided the time resolution necessary to refute these explanations. However, for improvements in dating methods to have a revolutionary impact on the archaeology of early modern human evolution, the correction of these flawed narratives can only be regarded as a first step. What is more important is that the discipline now embraces the opportunity to analyse cultural entities in terms of their internal temporal structure, and hence to realign praxis with contemporary evolutionary theory.

The application of luminescence dating in American archaeology

Luminescence dating is underutilized in American archaeology given the theoretical advantages of direct dating that it confers. Recent advances in understanding the physical processes underlying the method have also made it more reliable as a dating tool. This research as well as potential applications is reviewed.     

INFRARED STIMULATED LUMINESCENCE DATING OF ARCHAEOSEDIMENTS

In this study the feasibility of infrared stimulated luminescence (IRSL) for dating loessic colluvial sediments, deposited as a result of human activity, is investigated. It is demonstrated that the ‘IRSL-clock’is reset after a few minutes of daylight exposure even under foggy weather conditions. Samples of independently known age were taken at the Neolithic Bruchsal Aue site in south-west Germany. Different laboratory procedures are tried and a method is suggested (narrow wave-length band in the blue, preheat at 220° C for 5 min) to overcome age underestimates. This laboratory technique yielded archaeologically reasonable ages for colluvial sediments and hollow fillings. The IRSL-ages demonstrate that the deposition of the colluvia is related to soil erosion triggered by human activities, such as wood clearing and agriculture. The successful dating of archaeosediments has a great potential for applications in environmental archaeology as well as in geomorphology and in particular for the reconstruction of man-landscape interactions in central Europe.     

Household and Community Archaeology at the Chumash Village of Niaqla,Santa Rosa Island,California

Abstract

Several studies on the North American Pacific Coast have demonstrated the importance of household and community archaeology for documenting hunter-gatherer sociocultural dynamics. Household archaeology in coastal southern California is limited, leaving a significant gap in our understanding of a fundamental aspect of ancient human social life on the Pacific Coast. The Chumash village of Niaqla (CA-SRI-2), located on Santa Rosa Island, California, is one of the few island sites where several houses have been excavated. Cemeteries and parts of at least 10 houses were excavated in the 1940s–1960s, but only limited details have been published. Analysis of field notes, artifacts, photographs, and maps from these excavations, supplemented by additional testing, mapping, and radiocarbon dating at the site, demonstrate that Niaqla was a vibrant community, with over 20 houses, occupied for more than 2000 years. Unlike houses along the northwest coast of North America, Island Chumash houses required substantially less labor and planning, but were important locations of craft production, subsistence practices, and other activities, illustrating variability in the structure and function of houses and communities among complex hunter-gatherers.

Archaeological investigations and OSL dating of terraces at Ramat Rahel,Israel

Abstract

Dating terraces, the most prominent feature of the agricultural landscape in many parts of the world, is a problem for archaeologists. This study presents an interdisciplinary approach that combines archaeological survey and excavations with direct sediment dating of terrace fill using Optically Stimulated Luminescence (OSL). The study focuses on Ramat Rahel, a multi-period site located in the southern outskirts of modern Jerusalem, Israel, where, on a defined terraced slope chosen for a small-scale landscape archaeology project, three main phases of terrace construction and use were identified. The earliest phase dates to the Late Byzantine/Early Islamic period, the second to medieval times, and the last to the Ottoman period. The results enable a comprehensive reconstruction of the changing local landscape through time and demonstrate the validity of OSL, when combined with archaeological investigations, as a reliable method for terrace dating.     

Oaks,tree-rings and wooden cultural heritage: a review of the main characteristics and applications of oak dendrochronology in Europe

We overview the recent development of oak dendrochronology in Europe related to archaeology and art-history. Tree-ring series of European oaks (Quercus robur and Q. petraea) have provided a reliable framework for chronometric dating and reconstruction of past climate and environment. To date, long oak chronologies cover almost the entire Holocene, up to 8480 BC and the network over the entire area in which the two oaks grow is being improved. We present the main characteristics of oak ring series and discuss the latest methodological advances in defining the calendar year in which the tree-rings were formed and in interpreting such dating in terms of the age of a wooden object. Dendrochronology has established itself as a standard dating tool and has been applied in a wide variety of (pre-)historical studies. Archaeological wood, historical buildings, works of art (such as panel paintings and sculptures) have been successfully investigated. Recent advances in dendro-provenancing have helped to obtain more information on the timber trade in the past. Information on past forest structures, silviculture and timber use have become available through scrutinizing historical and contemporary ring-width patterns.

OSL dating and lithological characteristics of loess deposits from Biały Kościół

Absolute dating using luminescence methods is widely applicable in geology, geomorphology, palaeogeography and in archaeology in establishing ages of sediments and archaeological artefacts. By creating absolute time scales for different events in the history of Earth scientists are able to reconstruct changes in climate and environment in the past, and the history of colonization and development of culture.     

Early medieval T⊘nsberg — dating problems and the results

According to the 13th century Icelandic Saga writer Snorre Sturlasson, there was a marketplace (in old Norwegian: Kaupstadir) in the T?nsberg area by the end of the 9th century. The origin of the medieval town of T?nsberg has therefore been much discussed in the light of this statement. Viking Age and early medieval settlements often lack material datable by archaeology alone. In T?nsberg radiocarbon dating has been used to distinguish between Viking Age deposits and medieval deposits, when stratigraphy alone does not state the differences. However, this dating method has produced various results and there is obvious need for a local calibration.     

The effects of geographical distances on pottery assemblage similarities: a case study from Northern Iroquoia

A basic premise of archaeology is that the more frequently two human populations interacted with one another the more similar was their material culture. A corollary of this is that the closer two human populations are to one another geographically, the more frequently they will interact. This corollary has been expressed in the archaeological study of northern Iroquoia since the 1950s on the basis of historical ethnic territories. The expectation has been that after ca. A.D. 1000 to 1300 there was more interaction between village populations within these historical territories than between village populations located in different historical territories. Here I test this corollary with pottery decoration data from 114 northern Iroquoian village sites dating from c. A.D. 1350 to 1640. Results indicate that geographic distance has little effect on pottery assemblage similarity.     

Psychic Archaeology: Theory,Method, and Mythology

Abstract

In contemporary society the growth of mystical, occult religious cults is providing the public with new interpretations about prehistory, human evolution, and ancient civilizations. One spiritualistic search for the human past is named psychic archaeology and it preaches the gospel that traditional field archaeology is limited, obsolete, and largely useless because it has not been getting the right answers about antiquity. The doctrine continues that the truth about man's cultural origins is obtained from psychic mediums who have the occult power actually to visit prehistoric times in visions and to exchange messages with the spirit world. These psychic mediums are widely believed to have the ability to dowse for artifacts and in various ways communicate with the ghosts of the dead. One looks in vain to the professional journals for discussions of the fallacies of psychic archaeology, and. Partly because of the lack of a professional response to the occult challenge, these new religious movements have grown unchecked despite errors, anachronisms, and false premises in their astonishing claims about the origin and development of human society. This review article is concerned especially with recent publications of Jeffrey Goodman, Hans Holzer, and David Zink, along with a few other earlier authors; their books are cited in the text and in the footnotes.     

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.

The Archaeology of Al-Andalus: Past,Present and Future

Abstract

THIS PAPER PRESENTS AN OVERVIEW of the archaeology of al-Andalus (the Arabic name for Islamic Spain and Portugal), from its beginnings in the late 1970s to the present day. Innovative approaches and challenging theoretical stances made the archaeology of al-Andalus the spearhead of medieval archaeology in Iberia between the 1980s and 1990s. A problematic, and often conflicting, relationship between archaeology and history has characterised medieval archaeology in Spain since its inception, however, and a new awareness of these problems is emerging. This paper reviews past and current attitudes to such challenges and reflects on the future needs of the discipline. It also reflects on the politics of archaeology and on the role of medieval archaeology in revealing social change, which has until now been underrated.     

Humans in the Environment: Plants,Animals and Landscapes in Mesolithic Britain and Ireland

Environmental archaeology has historically been central to Mesolithic studies in Britain and Ireland. Whilst processual archaeology was concerned with the economic significance of the environment, post-processual archaeology later rejected economically driven narratives, resulting in a turn away from plant and animal remains. Post-processual narratives focused instead on enigmatic ‘ritual’ items that economic accounts struggled to suitably explain. Processual accounts of landscapes, grounded in economic determinism, were also rejected in favour of explorations of their sociocultural aspects. However, in moving away from plant and animal remains, such accounts lacked the ability to rigorously explore the specificities of particular landscapes and humans actions within them. This paper will bridge this gap by considering how palaeoecological and zooarchaeological analyses can be used to explore human interactions with plants and animals, which were key in developing understandings and relationships that ultimately structured landscapes, influenced past human actions and shaped archaeological assemblages.     

A Multi‐disciplinary Approach to the Archaeological Investigation of a Bedrock‐Dominated Shallow‐Marine Landscape: an example from the Bay of Firth,Orkney, UK

Investigation of shallow‐marine environments for submerged prehistoric archaeology can be hampered in many localities by extensive bedrock exposure and thus limited preservation potential. Using the concept of ‘seamless archaeology’ where land‐based archaeology is integrated across the intertidal zone through to the offshore, a multi‐disciplinary approach is essential. This approach taken in the Bay of Firth, Orkney uses geophysics, historical archive and ethno‐archaeology, coastal geomorphology, palaeo‐environmental analyses and sea‐level science, and allows a clearer understanding of the landscape in which prehistoric settlers lived. While acknowledging the limitations of the preserved environment, we are successful in identifying areas of archaeological potential on the sea‐bed for both upstanding structural elements as well as sediment preservation that contains evidence for human occupation. This has wider implications beyond Orkney's World Heritage sites to provide a blueprint for similar studies elsewhere in the coastal zone. © 2012 The Authors
