Three-dimensional laser scanning: potential uses for museum conservation and scientific research

Recent technological advancements have made a tremendous impact in the fields of biological anthropology and archaeology. Although advancements in DNA analysis have overshadowed other areas of progress in the subfields of biological anthropology, bioarchaeologists are now utilizing many other new forms of technology in their work. In particular, three-dimensional (3D) laser scanning offers a sophisticated method of documenting and studying prehistoric human skeletons. In recent years, portable laser scanning devices capable of creating high resolution images have become available, enabling researchers to scan and archive skeletal collections from archaeological sites and museum collections around the world. 3D laser scanners are inexpensive, simple to operate, and completely non-destructive to human skeletal material. A major benefit is that they offer a cost-effective method of creating a digital record of skeletal collections for museum archives. Since published research using 3D methods typically focuses on sophisticated analyses used to analyze 3D data that are difficult for the novice user to follow, in this paper we provide a simple and straightforward overview of 3D scanning methods aimed at non-specialists. We discuss how these methods can be used to preserve and document osteological material in museums, develop research ideas in the subfields of biological anthropology, and increase the potential for scholarly collaboration.     

Settlement history in the eastern Rub al-Khali: Preliminary Report of the Dubai Desert Survey (2006–2007)

Regional archaeological survey in desert areas of Dubai, U.A.E., has identified numerous archaeological sites in this rapidly changing landscape. Subsurface geophysical surveys have been undertaken in concert with surface collection and test excavation to document the extent and chronology of each site. Contrary to expectations that deserts were permanently abandoned following the end of the mid-Holocene pluvial phase around 4000 BC, two sites, Al-Ashoosh and Saruq al-Hadid, show evidence of substantial occupation during the late third and early first millennia respectively. These findings suggest that the Rub al-Khali supported human settlement much later than is generally thought, challenging traditional understandings of the region's cultural and environmental histories.     

The telltale potency of a simple milligram of charcoal found in a hearth left by Mesolithic reindeer hunters in the Norwegian mountains

The discovery and excavation of superimposed, information-rich Pre-Boreal hunting sites around the mountain lakes of Myrvatn and Fløyrlivatn in Southwest Norway have been the subject of archaeological debate. A brief review of research is presented here. In contrast to the well-preserved sites, settlement remains of a diametrically different order occur in the strongly water-eroded zone of the lakeshores: small, surface hearths in almost every stage of preservation, from evident hearths to diffuse and irregular scatters of fire-cracked stones. The latter category seems generally underestimated as a source of evidence. However, recent finds at Myrvatn demonstrate how even blurred, heavily eroded and almost intangible hearth remains, by the support of wood anatomical analysis, radiocarbon dating and intra-site comparison, may reveal concise, invaluable information both about the history of local use and regional landscape development.     

Herbivorous livestock dung: formation,taphonomy, methods for identification,and archaeological significance

Herbivore livestock dung has been identified in archaeological sites around the world. Focusing on dung from the ubiquitous Old World herbivorous domesticates – sheep, goats and cattle – this review deals with the materials found within dung that have relevance to archaeology. The natural and anthropogenic/cultural taphonomic processes that affect the preservation and identification of livestock dung, and the archaeological information that can be extracted through detailed studies of the context and content of identified livestock dung in archaeological sites is modeled and discussed.     

Archaeology and Development: the Tembladera Sites of the Peruvian North Coast

Abstract

Utilizing the example provided by a major water-control project planned for construction in the Jequetepeque Valley on the Peruvian north coast, this paper emphasizes a number of problems in the implementation of cultural resource-management programs in the Third World. The impact of this particular economic development program on the archaeological record is demonstrated by focusing on the project's most devastating aspect, the construction of a large dam in the up valley region just south of the town of Tembladera. Special attention is given to the threatened Chavin-related sites in this region, sites about which little is known other than that they are characterized by a highly valued ceramic style often found in private and museum collections.     

Paleoindian subsistence strategies and late Pleistocene paleoenvironments in the northeastern and southwestern United States: a tooth wear analysis

Paleoindians of North America entered a continent undergoing rapid climatic and environmental changes. This paper is a preliminary contribution toward obtaining a better picture regarding how climate and environmental change might have impacted the first settlers of North America. The Paleoindian sites we analyzed are, from the oldest to the youngest, Ingleside (Texas), Blackwater Draw Locality No. 1 (New Mexico), Hiscock Site (New York), and Plainview Quarry (Texas). Paleoenvironmental reconstruction involves identifying the dietary traits of ungulate species that might reflect the environmental conditions where they were living, and also where they might have been hunted by Paleoindians. Such an approach is realized through tooth microwear and mesowear analyses. Results indicate that a variety of food resources were available for the ungulates at these sites as well as the likely presence of mosaic environments around these sites which allowed Paleoindians to exploit resources in a large variety of habitats. The application of a method that allows for the estimation of the duration of occupation at archaeological sites reveals that results for Blackwater Draw and Hiscock Site indicate a long-term occupation of probably several months. However, during short events, Paleoindians were most likely hunting herds of horse and bison when these prey were available near the site. Results indicate that Plainview Quarry was likely used only for short-term occupations, with large game hunting focusing on bison. These patterns identified at the archeological sites studied are related to the fact that Paleoindians follow a high-technology forager model and frequently shifted their territory depending on the composition and distribution of the large mammal fauna.     

Estimating age and season of death of pronghorn antelope (Antilocapra americana Ord) by means of tooth eruption and wear

Age and season of death information for prey animals at archaeological sites can address issues such as season of site occupation and prey hunting or harvesting strategies. Unfortunately, adequate reference information for estimating age and season is lacking for many wild species, including pronghorn antelope. To address this problem, new methods of scoring tooth eruption and wear have been developed and have been applied to a sample of over 500 pronghorn mandibles to obtain improved eruption and wear schedules. One implication of this study is that ‘age class discreteness’ is an unreliable method for demonstrating mass mortality of prey. This study provides a much larger comparative sample than previously available, although larger known‐age mandible samples are still needed for pronghorn and many other wild species.

Extra! Extra! Read All About It: Newspaper Archives as Archaeological Site Survey

Relative to other historic documents, newspapers have received little attention from researchers as a source of archaeological data. Now that many historic newspapers have been digitized and placed online, this traditionally underutilized resource has the potential to yield new information about archaeological sites, especially those in heavily developed urban areas where sites are inaccessible or have been destroyed. In this article, a methodology is proposed by which archived newspapers might be searched for data about archaeological sites. A case study using newspapers from Allen County, Indiana and its principal city, Fort Wayne, demonstrates the utility of the methodology by producing evidence about many previously unrecorded archaeological sites.     

An evaluation of the site specificity of soil elemental signatures for identifying and interpreting former functional areas

Soil multi-element analysis is now a routine technique employed to help answer questions about space use and function in and around archaeological sites. The pattern of enhancement of certain elements, including P, Pb, Ca, Zn, and Cu, has been shown by numerous studies to correlate closely with the archaeological and historical record. Interpretation of these soil signatures, however, has generally been more problematic. One approach to the problem has been the use of ethnographic or “known” sites to guide interpretation, but how confidently can results from one site be extrapolated to another? This study of abandoned farms tests the site specificity of soil multi-element signatures of past space use through the use of discriminant models. Data analysis suggests that one to one comparisons of similar sites are much less accurate (38% accuracy) than comparisons based on a wider range of sites (59.3% accuracy), even when the latter have contrasting geology. The results highlight the importance of individual anthropogenic practices during occupation and abandonment in the development of diagnostic soil geochemical signatures.     

Sea bird fowling in southern Patagonia: a contribution to understanding the nomadic round of the Canoeros Indians

As well as providing data on meat yield, avian remains can be expected to give information on seasonality, an important parameter for understanding prehistoric hunting economies. An archaeological survey conducted in the Skyring Sea (Province of Magellan, Chile) between 1992 and 1994 provided bird bone assemblages that have been analysed with this aim in mind, of which 12 are discussed here. Cormorants and steamer ducks constitute 97 per cent of the specimens identified. The proportions of avian remains are compared with the mammals remains, and mostly show a predominance of the former. The status and seasonal distribution of animal resources are discussed in order to understand the motivation for such a specialization on bird hunting, when mammals (Artiodactyls and Pinnipeds) can bring a much higher yield of meat. This nomadic marine economy can best be understood when comparisons are made with other sites from the same cultural area. © 1997 John Wiley & Sons, Ltd.     

Limited yet informative: pathological alterations observed on human skeletal remains from third and second millennia bc collective burials in the United Arab Emirates

While syntheses of palaeopathological studies have been undertaken in many parts of the world, until recently little was known about human health in the past in the United Arab Emirates (UAE). Focusing on skeletal pathologies, this paper documents the results of the first synthetic palaeopathologlcal study for this country. The collections of archaeological human skeletal remains come from three sites dating to the third and two sites dating to the second millennia bc and consist predominantly of disarticulated, partially fragmented and often cremated remains. The paper initially discusses potential explanations for the neglected study of human skeletal remains from the UAE. This discussion is followed by an outline of the types of burial practices employed in the past in this region and their effects on preservation. The nature of the collections and the methodology employed in their study are described. Using specific headings, the pathological findings are then documented, followed by a discussion of the results of the skeletal analysis in light of the available archaeological evidence. Finally, it is shown that although limited by preservation, analyses of human skeletal remains provide valuable details about the types of diseases that affected people in the past in the UAE. While less detailed than some palaeopathological syntheses, the results presented in this paper lay the foundations for further work on humans in the past in eastern Arabia.

Context, curation, and bias: an evaluation of the Middle Paleolithic collections of Combe-Grenal (France)

The site of Combe-Grenal is arguably the reference site for the Mousterian of southwest France. Bordes excavated the site over a period of 13 years and generated a large collection of lithics and fauna from a deep series of 64 Lower and Middle Paleolithic levels. Though Bordes only partially published his work at the site, its long stratigraphic sequence and particularly its collections have been subjected to numerous studies over the years and have figured prominently in several long-running debates concerning the Mousterian. Recently, the authors undertook a project to inventory and analyzed these collections along with the documentation of their archaeological context. In so doing, however, a number of serious problems became apparent with the collection in its current state, problems that cannot easily be resolved given the state of the available documentation. These problems have important implications not only for results of studies based on these collections, but more generally, they also point to problems in terms of how archaeological collections are curated.     

A Retrospective and a Look Forward

Abstract

For 20 years (1974–1993), the “Antiquities Market” section of the Journal of Field Archaeology provided news and commentary on the illicit traffic in antiquities and on issues of cultural heritage relevant to field archaeologists from around the world. Much has happened in more recent years; military conflict, natural disaster;development, political or religious extremism, calculated looting, and the illicit sale of antiquities all combine to jeopardize the very existence of archaeology. The commodification of material culture is among the most pressing issues on the archaeological agenda. Links between collecting and looting continue to be hotly debated, and recent investigations illustrate how archaeological research may also unintentionally spur looting. Legislative efforts attempt to curb the plunder of sites and the illicit sale of antiquities. What is clear from the various efforts and questions is that globalization is bringing us closer together,and that we need a concentrated international initiative to document and preserve the archaeological record. Concrete proposals for such an initiative are required. The restoration of the “Antiquities Market” section is intended to reopen dialogue on these pressing issues by discussing specific sites in jeopardy and instances of looting, highlighting current trends, and encouraging all those who value the past to protect cultural heritage.     

Identifying Shell Middens With Historic Aerial Photos: An Example From California's Santa Cruz Island

Using 1929 aerial photos of western Santa Cruz Island, we identified numerous potential shell midden locations, followed by confirmation of site locations via field reconnaissance. Heavy grazing by sheep, cattle, and pigs closely cropped island vegetation in the early twentieth century, exposing shell middens now often covered with thick vegetation. We discuss the potential and limitations of early aerial photos as aids to archaeological site identification and management in island and coastal settings. Although results varied from island to island, we found historic aerial photos to be extremely useful for documenting previously unrecorded sites on Santa Cruz Island, ranging from historical EuroAmerican sites to Island Chumash sites dating to as much as 7250 cal BP. These methods may also be applicable to other islands around the world subject to heavy livestock grazing in the past, especially where introduced animals have been removed and recovering vegetation now obscures archaeological sites.     

PEAT-BOG SITES IN THE EASTERN URALS

Peat-bog sites are unique archaeological sources due to their ability to preserve organic remains which otherwise decompose in mineral soils. This opens up a wide range of prospects for the use of science-based methods in paleoenvironmental research. Relatively few peat-bog sites are known in Russia; most are located in the Eastern Urals and in the forest zone of the Russian Plain. At the Uralian sites, anthropomorphic and zoomorphic sculptures, vessels, transportation means, hunting and fi shing tools, and details of structures made from organic materials have been discovered. All these are highly relevant to archaeological reconstruction. Along with fi nds from numerous sites in mineral soils they provide a basis for multidisciplinary approaches to reconstructing the environments, lifestyles, and ideologies of prehistoric Northern Eurasia.     

Differential Avian Skeletal Part Distribution: Explaining the Abundance of Wings

An abundance of wings relative to other skeletal parts has been observed in avifaunal assemblages from many different types of archaeological sites from numerous locations around the world and of various time periods. Both cultural and post-depositional hypotheses have been proposed to explain this pattern. One of the most powerful explanations to account for this phenomenon is differential survival of avian elements due to bone density. Although bone density has not been systematically measured for all types of birds, I test this hypothesis using predictions derived from observations about the functional anatomy of birds using archaeological data from numerous sites in the Pacific Northwest Coast (U.S.A.). I conclude that the density hypothesis is not supported at these sites, and that other hypotheses must be examined further.     

Privatisation of Italian Cultural Heritage

Italy is home to much of the European cultural heritage, including artistic, archaeological, architectural and environmental heritage. Articles 7 and 22 (now 33), introduced in the Financial Act 2002 (now Law 112/2002) by the current Italian government, are privatising part of it. Already, objects from the mediaeval period to the 20th century have been sold to international investment firms and private investors for amounts that many Italian experts consider well below the median market price. Hundreds of other objects, among them temples, old cities, medieval palazzos, archaeological sites, museums, beaches and islands, are waiting to be sold. Currently, this case is not only a source of division in Italian politics but is also the subject of heated public debate. It highlights crucial social and cultural problems relating to global privatisation that the world community will have to face in the coming years.     

Cut and Tooth Mark Distributions on Large Animal Bones: Ethnoarchaeological Data from the Hadza and Their Implications For Current Ideas About Early Human Carnivory

Distributions of cut and tooth marks on the bones of large animals found in archaeological sites are increasingly used as sources of inference about the relative importance of hunting and scavenging in early human diets, and (by extension) about the role of meat-eating in human evolution. Here we review the empirical basis for these inferences in light of ethnoarchaeological data from the Tanzanian Hadza, a modern East African foraging population. Comparison of the Hadza data with those produced by other actualistic work indicates that while there may be a relationship between cut and tooth mark distributions and order of consumer access (human- versus carnivore-first), it is less clear-cut than many have suggested. Application of these results to the analysis of Plio-Pleistocene archaeological collections is further complicated by inconsistencies in the ways cut and tooth marks have been defined and counted, and by significant differences between patterns observed in modern control samples and those reported at ancient sites. These observations indicate that cut and tooth mark analyses are unlikely to speak effectively to questions about early human carnivory in the absence of: (1) better-warranted, more comprehensive expectations about the potential range of variation in past human carcass acquisition strategies, (2) a larger, more rigorously designed set of control experiments that model the archaeological consequences of these strategies, and (3) a larger, more consistently analysed archaeological data base. Even if these requirements are met, the idea of meat-eating as an important catalyst in the evolution of early humans will remain highly problematic, mainly due to problems involving the frequency and short-term reliability of carcass access.     

The Upper Paleolithic of the Russian steppe zone

The vast steppe area North of the Black Sea has been populated since the early Middle Paleolithic. The number of known sites dating to the Upper Paleolithic is increasing as research progresses, and today about 150 Upper Paleolithic sites have received some (although varied) degree of study. For a long time, the steppe zone was considered to have had a separate cultural-economic adaptation that differed drastically from that found in the periglacial province farther north. The difference was expressed in the specialization in bison hunting and in the very high mobility of the population. More recent archaeological research, described briefly in this article, presents a different picture: Subsistence was more varied, hunting was not limited to bison, and the settlement system indicates long periods of occupation of the sites. There were many local archaeological cultures, and study of the material remains indicates numerous contacts between the people of the steppe zone and those in Central Europe and the Caucasus and, by way of the Caucasus, with Western Asia.
