Coprolites attributable to humans, dated from the Pleistocene–Holocene transition, obtained from the archaeological site Cerro Casa de Piedra, Santa Cruz Province, were examined for parasites. The feces were processed by rehydration and spontaneous sedimentation using conventional parasitic procedures. Helminthic eggs recovered were identified as Trichuris sp., Calodium sp., other capilariids, and ancylostomid (Nematoda), probably Hymenolepis sp. and anoplocephalid (Cestoda); one oocyst attributable to Eimeria macusaniensis (Apicomplexa) was also found. According to the life-cycles and specificity of the parasites found, it is possible to suggest that some species (i.e., E. macusaniensis and Calodium sp.) represent parasites in transit or pseudoparasitism. Paleoparasitological results revealed the existence of an intensive relationship between parasites and humans in the Pleistocene–Holocene transition in Patagonia. Evidence suggests an early association among parasites, rock shelters and hunter–gatherers in the region. It is also postulated that the ancient lifestyles associated with caves and rock shelters were conductive to illness. 相似文献

Data of high resolution for reconstructions of archaeological site formation processes can be obtained only by the use of precise excavation methods and comprehensive recovery techniques using fine-mesh water screening, followed by meticulous sorting and quantitative studies of all the small organic components from the screens. These methods are generally used at human occupation sites, but are not often employed at paleontological or mixed human-carnivore sites. At the site of Bois Roche, an Upper Pleistocene hyena den, we have used these meticulous recovery techniques in combination with absolute dating, geoarchaeological observations, taphonomic analyses, studies of microvertebrates and pollen analysis. Correlation of the site environmental data from pollen and microvertebrate assemblages with the vegetation record of a deep-sea core taken in the Bay of Biscay have allowed us to constrain the ages provided by ESR dating of bovid teeth and to reconstruct the physical environment of the site with a degree of confidence rarely achieved by the use of fossil remains from archaeological sites alone. 相似文献

This article explores the relevance of acoustics as a factor for in the production and active use of Levantine rock art in Spain. The renowned rock art area of La Valltorta Gorge serves as a case study. Two experiments are described; the first assessed whether the sites with the most painted motifs had better acoustics than those with fewer motifs. The second tested which areas in La Valltorta Gorge had better acoustics and whether there was a difference between the acoustics of the decorated area and the contiguous sectors of the Gorge where no paintings have been found. In both experiments different sounds and pitches were used. The results suggest a strong relationship between the painted areas and the sonority of the place, with the major sites generally having provided the best results, with the exception of the sonority when facing the rock art panels. It is suggested that La Valltorta Gorge was chosen to be decorated with a view to increasing the perceptual impact of the rituals that may have been held at rock art sites due to the amplification caused by the echoing and resonance. 相似文献

Bones treated at low temperature do not present major modifications although, macroscopically, boiled bones may be distinguished from unboiled ones as they are smoother, lighter and more transparent. Such observations should correspond to textural modifications at a nanometric level and should depend on boiling time. In this study, contemporary human bones, boiled during various time intervals, were characterized using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD) and nitrogen adsorption (BET). The results were used to estimate the boiling time in four archaeological samples (Neolithic bones from Malalmuerzo cave, Spain). It is concluded, comparing Neolithic bones to contemporary ones and from the textural characterization at a nanometrical level, that two of the archaeological bones were boiled and that they were boiled for less than 6 hours. 相似文献

The study of black patches and spots in prehispanic bones of Tlatelolco and Tlapacoya is presented. The chosen characterization techniques, X-ray Fluorescence, X-ray Diffraction, Scanning Electron Microscopy, Energy Dispersive X-ray Spectroscopy, Infrared Spectroscopy and Gas Chromatography are complementary and they all conclude that the bone black pigment is constituted, mainly, by amorphous carbon and some mineral inclusions. Gas Chromatography and Infrared Spectroscopy show that the pigment is constituted by organic compounds as aromatic hydrocarbons, mainly bitumen. An explanation on how the spots were formed is proposed. 相似文献

This paper aims to bring together hitherto neglected archaeological data about the early medieval landscapes of Galicia (north‐west Spain), in order to understand the social transformations this ‘peripheral’ region underwent between the fifth and the ninth centuries and to frame them in the context of wider European debates. Despite its many limitations, the archaeology reveals that until the middle of the seventh century, the late antique society of Gallaecia experienced a previously unsuspected vitality. At this point a socio‐political fragmentation occurred, which was characterized by the strengthening of local power, until a further change took place with the progressive incorporation of Galicia into the Asturian kingdom in the ninth century. 相似文献

Making history—in the sense of writing it—is often set against talking about it, with most historians considering writing history to be better than talking about it. My aim in this article is to analyze the topic of making history versus talking about history in order to understand most historians' evident decision to ignore talking about history. Ultimately my goal is to determine whether it is possible to talk about history with any sense.
To this end, I will establish a typology of the different forms of talking practiced by historians, using a chronological approach, from the Greek andRoman emphasis on the visual witness to present-day narrativism and textual analysis. Having recognized the peculiar textual character of the historiographical work, I will then discuss whether one can speak of a method for analyzing historiographical works. After considering two possible approaches—the philosophy of science and literary criticism—I offer my own proposal. This involves breaking the dichotomy between making and talking about history, adopting a fuzzy method that overcomes the isolation of self-named scientific communities, and that destroys the barriers among disciplines that work with the same texts but often from mutually excluding perspectives. Talking about history is only possible if one knows about history and about its sources and methods, but also about the foundations of the other social sciences and about the continuing importance of traditional philosophical problems of Western thought in the fields of history and the human sciences. 相似文献
