Assessing Diet and Seasonality in the Lower Pecos Canyonlands: An Evaluation of Coprolite Specimens as Records of Individual Dietary DecisionsRiley, Timothy 2010 December 1900 (has links)
This dissertation presents an evaluation of coprolite specimens from the Lower
Pecos canyonlands as records of individual dietary decisions. Prior studies of coprolites
from this region have greatly expanded our knowledge of Archaic subsistence patterns,
but have not taken full advantage of the record of individual dietary decisions recorded
in each coprolite specimen. The menu, or dietary combinations, reflected in individual
coprolite specimens are assessed through the identification of several congruent
botanical components derived from the same food resource, phytoliths, fiber ultimates,
and epidermal sheets. The data is analyzed with hierarchical cluster analysis, an
exploratory statistical technique. The resultant menus reflected in these clusters are
evaluated with reference to the diet-breadth model developed for the known staple
resources of the canyonlands as well as the seasonal subsistence patterns observed in the
ethnohistoric record of modern-day Mexico and Texas. This same technique is also
applied to the coprolite data available from previous studies in the Lower Pecos
canyonlands.
Overall, the combined dietary data available for the Lower Pecos canyonlands
presents a similar dependence on desertic plant resources throughout the Archaic. Three
main menus are apparent in the specimens. The first menu consists of prickly pear
(Opuntia sp.) cladodes, or nopales, and was principally, although not exclusively,
consumed in the late spring. This menu is primarily consumed when other resources
were not readily available and may be considered a dependable but undesirable meal.
The second menu consists of pit-baked lechuguilla (Agave lechuguilla) and sotol
(Dasylirion sp.) caudices, or hearts, common throughout the cool season. This menu
entails high processing costs, but would provide a reliable caloric return. The third
menu exhibits a monolithic reliance on prickly pear fruits, or tunas, during the summer.
The ease of harvest and consumption is reflected in the seasonal dominance of this
resource, which was assuredly a highly desirable meal. The dietary patterns recorded in
the coprolite specimens from the Lower Pecos canyonlands demonstrate a seasonally
variable diet-breadth that incorporated low-ranked resources during times of seasonal
scarcity as well as a monolithic dependence on high-ranked resources when they were
available in the local landscape.

Contribution de la paléogénétique et de la paléogénomique à l’étude des sites archéologiques / Contribution of palaeogenetics and palaeogenomics to archaeological site studiesBon, Céline 23 September 2011 (has links)
La Paléogénétique a pour but l’analyse de l’ADN de pièces archéologiques, et le renouveau de cette discipline tend à intégrer une dimension génomique par le séquençage massif des spécimens les mieux préservés. Les grottes, dont la température reste fraîche et constante, permettent la conservation de l’ADN. Nous avons analysé des échantillons du Pléistocène conservés dans des grottes, dont un site archéologique majeur, la Grotte Chauvet. L’étude a porté sur deux espèces, l’ours des cavernes, Ursus spelaeus et l’hyène des cavernes, Crocuta crocuta spelaea.À partir d’un échantillon particulièrement bien conservé de la Grotte Chauvet, nous avons séquencé le génome mitochondrial de l’ours des cavernes et établi la phylogénie de cette espèce éteinte. Nous avons montré que l’ours des cavernes est une espèce proche des ours bruns et polaires dont elle s’est séparée il y a 1,6 million d’années. Nous avons ensuite analysé la région de contrôle mitochondrial de plusieurs spécimens des Grottes Chauvet et des Deux-Ouvertures datés de 28 000 à 32 000 ans. La forte homogénéité génétique de cette population ardéchoise pourrait être corrélée à la disparition régionale de l’espèce.Enfin, nous avons réalisé l’analyse génomique de coprolithes d’hyène des cavernes. Nous avons mis en évidence des quantités importantes d’ADN nucléaire et mitochondrial dans les coprolithes et reconstitué le premier génome mitochondrial complet d’hyène des cavernes. La présence d’ADN de cerf élaphe, Cervus elaphus, nous permet de décrire une relation proie-prédateur du Pléistocène. / Palaeogenetics aims at analysing DNA from archaeological remains. New genetic sequencing technologies revitalize the discipline through genomic analysis. Because of cool and constant temperature, cave sites allow the preservation of ancient DNA. We carried out DNA analysis of Pleistocene specimens originating from cave sites, especially the Chauvet cave. We studied samples from two extinct species, the cave bear, Ursus spelaeus, and the cave hyena, Crocuta crocuta spelaea.Using a well-preserved sample from Chauvet cave, we characterized the 16,810 bp-long mitochondrial genome of the extinct cave bear, and established its phylogeny. We were able to ascertain that the cave bear is a sister-species to the brown and polar bears, and that the two lineages split about 1.6 million years ago. We also sequenced mitochondrial control region fragments of Chauvet and Deux-Ouvertures cave bear samples. These Ardèche bear specimens, dated back to 28,000-32,000 years BP, display strong genetic homogeneity that may be related to the imminent species extinction.Finally, we analysed cave hyena coprolites from the Coumère Cave by metagenomic DNA sequencing. As these fossilized feces still contain a high amount of mitochondrial and nuclear DNA, we were able to decipher the first complete mitochondrial genome for the cave hyena. We found DNA from the red deer, Cervus elaphus, thus depicting a Pleistocene predator-prey relationship.

Paleopathology: signs and lesions in skeletal remains of epidemics and diseases of Biblical times in Syro-PalestineGreeff, Casparus Johannes 30 November 2005 (has links)
This dissertation deals with the study of ancient diseases mentioned in the historical period of the Scriptures in the region of Syro-Palestine. The definition, history, methodology and etymology of the terms relating to biblical diseases are discussed. Leprosy, syphilis, plague and anaemia amongst other diseases leave skeletal signs and lesions. Paleopathologists may reveal these diseases by studying skeletal remains of the population of Syro-Palestine.
Criticisms and recommendations are offered for the practical paleopathologist, anthropologist or archaeologist. More interest should be taken in the study of coprolite in every new discovery of human remains. The scarcity of skeletal remains in the region is well known. The past and present law structure, the Halakah, may partly be to blame.
The future of paleopathology worldwide is undisputedly the biochemical science of DNA analysis. With this new science the role for macromorphological examination may diminish. The diseases mentioned in the Bible are finding it increasingly difficult to hide behind the words in the Scriptures. / Old Testament and Ancient Near Eastern Studies / MA (Biblical Archaeology)

Casting no shadow : overlapping soilscapes of European-Indigenous interaction in northern SwedenGreen, Heather F. January 2012 (has links)
The Sámi’s past activities have been documented historically from a European perspective, and more recently from an anthropological viewpoint, giving a generalised observation of the Sámi, during the study period of AD200-AD1800, as semi-nomadic hunter gatherers, with several theories suggesting that interaction with Europeans, through trade, led to the adoption of European activities by certain groups of the Sámi (Eiermann, 1923; Paine, 1957; Manker and Vorren, 1962; Bratrein, 1981; Mathiesen et al, 1981; Meriot, 1984). However, there is almost no information on the impact the Sámi had on the landscape, either before or after any adoption of European activities, and none investigating what cultural footprint or indicators would remain from Sámi or European occupation and/or activity within the typically podzolic soils of Northern Sweden. Consequently the thesis aims to contribute to the gap in knowledge through the formation of a podzol model identifying the links between anthropogenic activity and the alteration of podzol soils, and through the creation of soils based models which identify the cultural indicators associated with both Sámi and European activity; formed from the identification of cultural indicators retained within known Sámi and European sites. The methods used to obtain the information needed to achieve this were the pH and magnetic susceptibility from bulk soil samples and micromorphological and chemical analysis of thin section slides through the use of standard microscopy and X-ray fluorescence from a scanning electron microscope. The analysis revealed that the Sámi had an extremely low impact on the landscape, leaving hard to detect cultural indicators related to reindeer herding in the form of reindeer faecal material with corresponding phosphorous peaks in the thin section slides. The European footprint however, was markedly different and very visible even within the acidic soil environment. The European indicators were cultivation based and included phosphorous and aluminium peaks as well as a deepened, highly homogenised plaggen style anthropogenic topsoil rich in ‘added’ materials. An abandoned European site which visibly and chemically shows the formation of a secondary albic horizon within the anthropogenic topsoil also provides an insight into the delicate balance of cultivated soil in northern Sweden, whilst reinforcing the outputs identified in the podzol model. Due to the almost invisible Sámi footprint on the landscape, areas of overlap were impossible to identify however, there was no evidence of the adoption of European cultivation activities at any of the Sámi sites investigated. The only known area of interaction between the two cultures was an official market place which had been a Sámi winter settlement prior to its use as a market site. This site showed none of the reindeer based Sámi indicators or the cultivation based European indicators, but did contain pottery fragments which could be linked to trade or occupation. Overall, the thesis reinforces the low impact expected of the semi-nomadic Sámi and sheds light on the underlying podzolic processes influencing the anthropogenically modified soils of Northern Sweden. The podzol model is reinforced by several findings throughout the thesis and the soils based cultural indicator models for both Sámi and European activity have been successfully tested against independent entomological and palynological data and therefore provide reliable reference material for future studies.

Previous issue date: 2010 / A paleoparasitologia utiliza como principal instrumento de estudo a análise de coprólitos e sedimentos retirados do solo de sítios arqueológicos, latrinas e da área pélvica de esqueletos. Associando-se dados da arqueologia, antropologia e paleoparasitologia, entre outras ciências, é possível obter resultados consistentes sobre modo de vida e saúde das populações no passado. Neste trabalho foram analisadas amostras de três regiões diferentes das Américas. Um total de 59 amostras de coprólitos e sedimentos provenientes de sítios arqueológicos localizados na área arqueológica de São Raimundo Nonato, que engloba o Parque Nacional Serra da Capivara (PNSC), Piauí, Brasil, foram analisadas. Esta região apresenta sítios com datações bastante antigas obtidas na área do Parque, com evidência de atividades humanas datadas aproximadamente de 50.000 anos; 12 amostras provenientes do sítio arqueológico Antelope Cave, localizado no Arizona, EUA. Assim como o PNSC, este sítio possui a presença de cerâmica e a iniciação da agricultura pelos grupos pré-históricos naquela região; e 15 amostras retiradas diretamente da região pélvica de sepultamentos provenientes do sambaqui Cubatão I, localizado em Joinville, Santa Catarina, Brasil. Este sítio arqueológico é, na verdade, um desafio metodológico devido ao clima e a atividade biótica do solo da região que não permitem boas condições de preservação do material arqueológico. A análise de resíduos alimentares destas diferentes regiões arqueológicas forneceu dados a respeito da dieta de populações antigas e a relação entre a presença de parasitos e o encontro de plantas com propriedades anti-helmínticas, e ainda foi possível a determinação de casos de falso parasitismo. / Paleoparasitology uses, as the main tool to study, the analysis of coprolites and sediments removed from the land of archaeological sites, latrines and the pelvic area of skeletons. Joining data from archeology, anthropology and paleoparasitology, among other sciences, it is possible to obtain solid results on livelihoods and health of people in the past. On this study were analyzed samples from three different regions of the Americas. A total of 59 samples of coprolites and sediments from archaeological sites located in the archaeological area of São Raimundo Nonato, which includes the National Park Serra da Capivara (PNSC), located in Pernambuco, Brazil, were analyzed. This region has sites with the oldest dating obtained in the Park, with human activities recorded from 50.000 years BP; 12 samples from the archaeological site of Antelope Cave, located in Arizona, USA. This site, just like PNSC, has features such as the presence of pottery and the initiation of agriculture by prehistoric groups in the region, and 15 samples taken directly from the pelvic region of burials from the sambaqui Cubatão I, located in Joinville, Santa Catarina, Brazil. This archaeological site is actually a methodological challenge due to the climate and soil biotic activity in the region that don't allow good conditions of preservation of the archeological material. The analysis of alimentary residues of these different archaeological areas supplied data regarding the diet of old populations and the relationship between the presence of parasites and the encounter of plants with anthelminthic properties, and it was still possible the determination of cases of false parasitism.
