Paleoethology as a tool for the development of archaeological models of land-use: the Crimean Middle Palaeolithic

The principal aim of our research is to capitalize on the close relationship between prehistoric hunters and prey to develop spatial models for the investigation of land-use patterns. Ideally, these models should be useful both as predictive tools for designing regional archaeological surveys, and as analytical tools for studying the distribution of known archaeological sites. Here, we build upon a basic G.I.S. model (including standard environmental variables such as slope, aspect and distance to water) adding a paleoethological variable in the form of range reconstructions for the regionally dominant, prehistoric human prey species: Equus hydruntinus.     

First dendroarchaeological dates of prehistoric contexts in South America: chullpas in the Central Andes

Despite the existence of long-lived tree species with excellent tree-ring characteristics, the use of dendrochronological techniques for dating archaeological contexts has been very limited in South America. Recent research in the Bolivian Altiplano of the Central Andes has yielded a network of Polylepis tarapacana chronologies that goes back to the 13th century. This species was regularly used by local populations since pre-Columbian times as raw material for beams, lintels, hooks and other architectural features in houses, storage chambers, and sepulchers. The aim of this study is to argue in favor of the potential of P. tarapacana for providing high resolution dates of significant archaeological events during the pre-Columbian era. The chronology of chullpas (burial towers and storage chambers) in the southern Andean Altiplano is used as a case study. Growth rings from P. tarapacana have provided several centennial-length dendrochronological records including a reference regional chronology covering the last 786 years in the Central Andean highlands. Based on this long reference chronology calendar years were assigned to woody pieces from pre-Hispanic chullpas. Dendroarchaeological results are consistent with contextual evidence and most radiocarbon dates from woody samples and related archaeological items. Our results indicate that P. tarapacana has a high potential for providing annually-resolved tree-ring dates for archaeological contexts in the Altiplano since the early 13th century.     

Wild or domesticated? An ancient DNA approach to canid species identification in South Africa's Western Cape Province

The fragmentary remains typical of archaeological fauna can prove impossible to identify when confronted with closely related sympatric species. In southern Africa domesticated dogs (Canis familiaris) and black-backed jackals (Canis mesomelas) pose just such a problem, rendering difficult an accurate assessment of the timing of arrival of domesticated dogs in the region. Contextual evidence has suggested that canid remains from four Later Stone Age archaeological sites were likely to be domesticated dogs rather than jackals, and were subjected to ancient DNA analyses to determine species. Every tested specimen proved to derive from black-backed jackals. These data provide not only an unexpected window on southern African prehistory, but also highlight the value in applying ancient DNA techniques to archaeological species identification.     

Endangered species,archaeology, and stable isotopes: huemul (Hippocamelus bisulcus) isotopic ecology in central-western Patagonia (South America)

The management and conservation of animal species should be based upon a long-term analysis that considers its geographical distribution and feeding patterns. The study of carbon and nitrogen stable isotopes on skeletal remains provides a quantitative approach to the paleodietary reconstructions and constitutes a potent tool for comparing behavioral aspects of the fauna. In this paper we present the first set of isotopic values for modern and archaeological samples of Huemul (Hippocamelus bisulcus) from the forests of Central-western Patagonia, Chile. Contrary to initial expectations, our analysis indicates that there is no evidence of an important incidence of the canopy effect on the δ¹³Ccollagen values, which we suggest is due to an ecological selection that drives the huemul to focus its predation on open sectors within the forest. On the other hand, a wide range of δ¹⁵Ncollagen values for huemul was verified. This could reflect the N impoverishment of the forest soils and provide an interesting ecological indicator. The long-term information offered by the archaeological record provides the necessary context for decision-making conducive towards the preservation of Hippocamelus bisulcus in Patagonia.     

Studies on Amerindian dogs, 3: Prehistoric wolf/dog hybrids from the northwestern plains

Discriminant function analysis is an invaluable statistical tool for the taxonomic identification of hybrids between various extant species of Canis in the eastern United States. This technique has recently been applied to the taxonomic identification of canid skulls from several Wyoming archaeological sites. Analysis indicates most canid remains, originally identified as wolf (Canis lupus), to be wolf/dog hybrids exhibiting constant and continual backbreeding to the local wolf populations. The spatial and temporal extent of the form is discussed.     

Some chronological implications of a fossil molluscan assemblage from a neolithic site at Brook,Kent, England

The later post-glacial history of a valley in the chalk escarpment near Brook, Kent, is described, based on molluscan stratigraphy, archaeological evidence and radio-carbon dating. Differences in size and colour banding, respectively, of fossil and living representatives of two species of land snails, Pomatias elegans (Müller) and Cepaea nemoralis (L.), are correlated with climatic change during the post-glacial period. The problems of the use of fossil shells of these species as samples for radiocarbon dating are discussed.     

Differentiating Aspen and Cottonwood in Prehistoric Wood from Chacoan Great House Ruins

Accurate taxonomic identification is an essential part of archaeological wood analysis. However, making identifications more precise than the genus level is usually not possible since species within the same genus typically possess very similar cellular morphology. This paper describes a method for distinguishing aspen (Populus tremuloides) from cottonwood (Populus fremontii, Populus angustifolia, Populus acuminata) in samples of wood collected from the San Juan Basin in northwestern New Mexico and southwestern Colorado. This method is then applied to archaeological wood samples from the Anasazi great house at Aztec Ruins National Monument in Aztec, New Mexico. The results of this study demonstrate that quantifiable differences do exist between aspen and cottonwood species and that the technique can be used to separate archaeological specimens of Populus wood.     

Studies on Amerindian dogs: Taxonomic analysis of canid crania from the Northern Plains

Archaeological investigation of the economic role of domestic versus wild canids among late prehistoric and historic villagers in the Northern Plains has long been hindered by difficulties in reliably distinguishing between remains of different species, especially dogs (Canis familiaris) and wolves (Canis lupus). Taxonomic confusion is the result of deliberate human selection for large, strong dogs for use as draft animals, and occasional but probably consistent hybridization between dogs and wolves. Discriminant analysis is used to help identify 33 archaeological canid crania from the Northern Plains, many of which are taxonomically confusing. Reference samples for classification of these specimens consist of six groups of modern or archaeological dog, wolf and coyote (Canis latrans) crania from North America. Thirteen measurements are used. Analysis indicates that, relative to wolves, the dogs tend to have proportionally wide posterior cranial vaults, short snouts and palates, steeply rising foreheads, and small teeth. Although convincing evidence for dog—wolf hybrid specimens from recent Plains archaeological contexts is lacking, the identification of such specimens probably has little practical significance with regard to canid domestication in general. Compared to dogs, a greater proportion of specimens identified as wolves exhibit evidence of butchering.     

Defining an indicator package to allow identification of ‘cesspits’ in the archaeological record

This paper summarises the insect, plant macrofossil and other environmental evidence from a large number of deposits, thought to be cesspits, at a range of archaeological sites. A potential ‘indicator package’ (sensu Kenward and Hall, 1997), consisting of a range of biological materials and archaeological artefacts, is outlined which should allow a more accurate identification of cesspits in the archaeological record enhancing further studies of the rich evidence often preserved in them.     

Stable hydrogen isotopes of bone collagen in palaeodietary and palaeoenvironmental reconstruction

The stable hydrogen isotope ratios (δD) of bone collagen in archaeological human and animal samples demonstrate a trophic level effect, with increasing δD from herbivores to omnivores to humans, in steps of 10–30‰. In addition the archaeological sites studied (Yarnton, Eton Rowing Lake, Danebury Environs–Suddern Farm, and Windmill Hill in the UK, Balatonszárszó in Hungary, and Huari in Peru) demonstrate geographical variation in δD. The detection of manuring in prehistory by comparison of δ¹⁵N to δD values in humans and a local herbivore (cattle) is also considered. This work is the first to measure δD in a large number and range of archaeological samples, with several animal species and humans. It demonstrates unequivocally that δD is different between species in ancient material, increasing from herbivores to omnivores to carnivores.     

Locally diagnostic phytoliths of wild rice (Zizania palustris L.) from Minnesota,USA: comparison to other wetland grasses and usefulness for archaeobotany and paleoecological reconstructions

Wild rice (Zizania spp.) is an important native grain of north-central North America, with spiritual and subsistence significance to many native peoples. Due to lack of suitable proxies, its past distribution and pattern of use are poorly known. This study demonstrates the diagnostic value of silica phytoliths from Z. palustris as a proxy tool to detect its past occurrence in a variety of paleoenvironmental and archaeological contexts. Our main findings are: 1) Dominant wetland grass species in Minnesota produce phytoliths distinct from Zizania phytoliths; 2) Closely related Leersia oryzoides produces a few Zizania-like phytolith morphotypes; however, these potential confusers can be identified based on 2-D and 3-D morphologies; 3) Z. palustris produces a wide variety of phytolith morphotypes, many of which are only found in certain parts of the plant (e.g., Inflorescence Type 1 from the spikelet); 4) Z. palustris produces 23 locally diagnostic phytolith morphotypes that can be used to determine the presence and abundance of wild rice in modern and paleo lake sediments; and 5) Wild rice phytolith Inflorescence Type 1 is the morphotype most likely to be observed in archaeological contexts, and may be unequivocally diagnostic for the genera Zizania.     

Correlating archaeological and palaeoenvironmental records using a Bayesian approach: a case study from Sutton Common,South Yorkshire,England

This paper presents a case study aimed at correlating archaeological ‘events’ (obtained from radiocarbon measurements and dendrochronology) from the site of Sutton Common with a radiocarbon-dated pollen sequence obtained from a palaeochannel deposit adjacent to the area of the main archaeological activity. It demonstrates the use of a Bayesian approach to quantifying whether the timing of palynological ‘events’ interpreted as reflecting anthropogenic impacts are likely to be associated with archaeological ‘events’. The results suggest that Bronze Age activity in the form of a mortuary enclosure and associated cremation burials are probably not contemporary with the palynological evidence for disturbance to the oak–hazel woodland in this period. Subsequent evidence for local woodland clearance and agriculture is estimated to precede the construction of the large Iron Age enclosure in 372 BC, with increases in ‘anthropogenic indicators’ following this ‘event’. The construction of the site does not appear to have had a pronounced impact on the local vegetation, with hazel the only woody taxon to show clear reductions. Despite the use of a substantial number of oak timbers in the enclosure palisade, percentages of oak remain remarkably stable. Later farming activity on the site probably post-dates the end of activity in the enclosures. The value of the methodology is discussed in relation to quantifiable and robust correlations of archaeological and palaeoenvironmental narratives of landscape and human activity.     

The biological and archaeological implications of the beetle Aglenus brunneus (Gyllenhal) in ancient faunas

The distribution and ecology, as far as they are known, of the Colydiid beetle Aglenus brunneus (Gyll.) are summarized and the significance of its records from archaeological sites considered. The supposition that A. brunneus originated in North America (Peyerimhoff, 1945) is questioned in the light of the ancient records. The species is used to illustrate some of the general principles and problems involved in the theoretical reconstruction of past environments from ancient faunas.     

BUTCHERING PATTERNS AND SPATIAL DISTRIBUTION OF FAUNAL ANIMAL REMAINS CONSUMED AT THE LOS MILLARES CHALCOLITHIC SETTLEMENT (SANTA FE DE MONDÚJAR,ALMERÍA,SPAIN)

The archaeological settlement of Los Millares (Santa Fe de Mondújar, Almería) is located in the Mediterranean coastal area of southern Spain. This archaeological site constitutes one of the most important settlements belonging to the Copper Age in the Iberian Peninsula and has given its name to the ‘millariense’ culture. The settlement has been completely excavated, yielding major archaeological faunal remains, with 27,426 bone fragments classified by researchers from Munich University (Germany). In this paper, we apply different statistical methods (mainly χ² analysis) to study the spatial distribution of bones from domestic and wild animals, reconstructing the patterns of appearance within specific functional spaces. These functions can be associated with meat consumption (sites to cut the animals into small pieces, areas where the meat was eaten, garbage sites, etc.) and the production of handmade objects (bone tools, stone tools, etc.). The results show different spatial distributions of faunal remains within the areas of the settlement, according to the animal species and particular parts of the animal skeleton, as well as the age and the sex of individuals. The findings reflect social behaviour that relates the consumption of certain species to a specific sector of population, and such behaviour can be discerned in the animal remains. Moreover, there is evidence regarding economic matters, such as meat production and the exchange of animals, which require further research.     

Ectopic paragonimiasis from 400-year-old female mummy of Korea

Of the parasite eggs discovered in ancient samples from Korean archaeological sites, Paragonimus spp. are of particular importance in that they are regarded as one of the most insidious trematode infection sources. Although their infection prevalence decreased rapidly in the early 20th century, archaeoparasitological studies on the species are still required, as historical knowledge of paragonimiasis remains far from comprehensive. Fortunately, we recently were given a chance to examine a medieval Korean mummy in a good state of preservation. Using morphological techniques, we discovered evidence of ectopic paragonimiasis in the sample from the 17th-century female. When the ITS 2 gene was extracted, amplified and sequenced from Paragonimus eggs, it showed 100% homology to the sequences of modern Paragonimus westermani reported from Korea and Japan, forming a cluster distinct from South Asian P. westermani. Our report is the first-ever analysis of ancient Paragonimus DNA from any archaeological field in the world. The ectopic paragonimiasis diagnosis made in this study, especially involving the liver sample, also is the first of its kind in archaeoparasitology.     

Autochthony and orientation patterns in Olduvai Bed I: a re-examination of the status of post-depositional biasing of archaeological assemblages from FLK North (FLKN)

Recent excavations at FLK North (Olduvai Gorge, Tanzania) have produced new information on the orientation of archaeological materials at various levels of the site. This information includes the uniform distribution of material azimuths, which contrasts with previous inferences of highly patterned orientations of materials in the Bed I archaeological sites. Those previous inferences of patterned material orientations are based on Mary Leakey's 50-year-old drawings of artifact and fossil bone distribution, but are not verified by our precise measurements of archaeological objects made in situ. Nor do those previous results agree with the general lack of geological, geomorphological, and/or taphonomic data that would indicate significant post-depositional movement of archaeological materials in the sites. We argue here that Leakey's drawings are incomplete (only portions of each assemblage were drawn) and inaccurate in their representation of the original locations, shapes and orientations of most archaeological specimens. This argument is supported by several important mismatches in object representations between a photograph taken of a small portion of the FLK 22 Zinjanthropus site floor before the removal of the archaeological items, and the sketch of the same area drawn by Leakey. Thus, we conclude that primary orientation data of excavations (i.e., direct measurements taken from items) generated prior to object removal are the only valid indicators of the relative isotropy or anisotropy of these important paleoanthropological assemblages.     

Study of interactions between polyethylene glycol and archaeological wood components by C high-resolution solid-state CP-MAS NMR

While use of polyethylene glycols, PEG, polymers for archaeological wood conservation has been well established, there is almost no study of such composite materials with carbon thirteen high-resolution solid-sate NMR. We demonstrate that NMR is an useful analytical tool to characterize rapidly samples of conserved wooden objects. By choosing an appropriate value of the contact time (from 3 to 5 ms) for which the PEG component gives only a small residual NMR signal in the CP-MAS experiment, it is possible to edit selectively the spectra of the wood components. It allows one to visualize the degradation extent of the archaeological wood even when the conservation processes have been already applied. Moreover, by studying the kinetics of CP-MAS experiments, the time constants, T_1ρH and T_CH values for PEG moiety were computed. From these data, it is shown that either in the crude commercial product or in incorporated in archaeological woods, two components are present and they are the signatures of crystalline (or ordered) and amorphous (or disordered) molecular domains. Moreover, it was shown in the archaeological woods that almost 30% of PEG was in close molecular interactions with lignins. This study is the first evidence that the PEG in conserved wood can interact at a molecular level with wood components. It also demonstrates that the PEG diffuses inside the residual cell walls of archaeological wood. This data are important for scientists in charge of process development for the conservation of wooden artifacts.     

Chemical analyses of organic residues in archaeological pottery from Arbon Bleiche 3, Switzerland – evidence for dairying in the late Neolithic

Fatty acids distribution and stable isotope ratios (bulk δ¹³C, δ¹⁵N and δ¹³C of individual fatty acids) of organic residues from 30 potsherds have been used to get further insights into the diet at the Late Neolithic (3384–3370 BC) site of Arbon Bleiche 3, Switzerland. The results are compared with modern equivalents of animal and vegetable fats, which may have been consumed in a mixed ecology community having agrarian, breeding, shepherd, gathering, hunting, and fishing activities. The used combined chemical and isotopic approach provides valuable information to complement archaeological indirect evidence about the dietary trends obtained from the analysis of faunal and plant remains. The small variations of the δ¹³C and δ¹⁵N values within the range expected for degraded animal and plant tissues, is consistent with the archaeological evidence of animals, whose subsistence was mainly based on C₃ plants. The overall fatty acid composition and the stable carbon isotopic compositions of palmitic, stearic and oleic acids of the organic residues indicate that the studied Arbon Bleiche 3 sherds contain fat residues of plant and animal origin, most likely ruminant (bovine and ovine). In several vessels the presence of milk residues provides direct evidence for dairying during the late Neolithic in central Europe.
