El Mirón is a large cave in the Cantabrian Cordillera of northern Spain that presents a long archaeostratigraphic sequence radiocarbon-dated by over 60 assays to between 41,000 and 2000 BP. The sediments, collected from four areas within the cave and sieved-washed with fine wire meshes, contain microvertebrate remains of fish, frogs, lizards, birds and mammals, of which the latter are most abundant. Preliminary taphonomic analysis suggests that the microvertebrates were naturally collected by owls and (less) small carnivores. Small mammal assemblages are useful for palaeoenvironmental reconstruction because they are linked to particular habitats and are sensitive to environmental changes. The small mammals from El Mirón are ideal for this because sample sizes are large, bone preservation is good, and the stratigraphic sequence is long. In this paper we reconstruct the late Quaternary environments in the Cantabrian region of Spain using small-mammal assemblages from El Mirón Cave. On the basis of the ecologic adaptations of this suite of fauna, the majority still extant, we have identified seven habitat types, which are plotted through time. The evolution of the small mammal assemblages at El Mirón reveals seven major climatic shifts that correspond closely to the climatic changes recognized in the Iberian Peninsula during the last 41 kyr.  相似文献

Between 1985 and 2007 overall nineteen human skulls dating to the Late Neolithic period were recovered at Kö?k Höyük, which lies within the borders of Bor, a district of the Ni?de Province in Central Anatolia. One of these skulls belongs to a child and the remainder to adult males and females. The plastered skulls may have been laid on or wrapped in mats and exposed either singly or in groups on a plaster surface inside the house. Among thirteen of these skulls the mouths, noses, eyes and ears were depicted with clay and painted with red ochre, while the remaining six were untreated. Two headless skeletons were also found in situ underneath the floor inside the house. One of these skeletons belongs to a child aged approximately 15–16 years old and the other belongs to an adult female. The modeled human skulls were encountered in the second and third cultural levels of the Late Neolithic period indicating that this characteristic mortuary practice lasted for quite a long time and likely disappeared by the Chalcolithic at Kö?k Höyük.  相似文献

The combined application of remote sensing techniques is often the most effective way for deepening the knowledge on very large archaeological sites (several hectares). In particular, geophysics and aerial photography could yield very detailed information on buried structures not only outlining their location but also, in many cases, defining their planimetry. Moreover, the accurate geocoding of different data sets and the use of GIS for their integration allow to extract the most comprehensive information from a combined study.  相似文献

A methodology is described by which spatial patterns of land use were reconstructed from pollen analyses on anthropogenic sediments at a recently excavated early Neolithic timber ‘hall’ in north east Scotland. The anthropogenic sediments were from a deep, small diameter pit within the building. They present numerous taphonomic and interpretative challenges to the analyst, but from this type of deposit, the power to estimate quantitatively the vegetation structure around the archaeological site makes such difficult deposits very significant. A rigorous methodology is firstly described, therefore, by which confidence in ecological interpretation can be established. Secondly, the source of pollen in the deposit is evaluated. Thirdly, the possible pollen source area and structure of the surrounding vegetation are estimated by quantitative simulation modelling. Finally, these analyses are compared with region-scale pollen analyses from nearby conventional wetland deposits with much larger pollen source areas. The pollen assemblages recovered probably reflect land uses adjacent to the ‘hall’ and up to 2.5 km around. Cereal cultivation was the most important land use immediately around the ‘hall’, possibly grown between stands of scrub Corylus (hazel) woodland. These intensive but local-scale land uses cannot be discerned in region-scale pollen analyses.  相似文献

This paper presents preliminary results of new radiocarbon dating of human, faunal and fish skeletal remains from a number of the cemeteries from the Middle and Lower Dnieper Basin, Ukraine. The results appear to demonstrate the presence of a radiocarbon reservoir effect during the Neolithic–Eneolithic periods, the first time that this has been identified in this region. The data indicate that the radiocarbon reservoir effect is currently only evident during these periods, and not in the earlier Epipalaeolithic–Mesolithic periods, prompting the suggestion that the radiocarbon reservoir effect is associated with elevated fish consumption from the Neolithic period onwards.  相似文献

Radiocarbon dates on marine shells have not been used as extensively as charcoal or bone dates for the setting up of absolute chronologies because interpreting these dates is complicated by the marine radiocarbon reservoir effect. Nevertheless marine shellfish were used widely at least during the Holocene and their shells are abundant and usually well preserved in archaeological deposits located near shorelines. Consequently prior research concerning the oceanographic conditions and the marine radiocarbon reservoir effect of a particular coastal area is needed in order to set up reliable chronologies for that region. Values of regional marine radiocarbon reservoir effect – ΔR – of coastal waters off Atlantic Iberia, some of its variability along the Holocene and its correlation with the upwelling phenomenon were determined during previous research. More data related to the ΔR values for western Portuguese coastal waters during the Late Neolithic and the Chalcolithic, a time interval badly sampled in previous research, were recently obtained. These values can be compared with ΔR values already determined for the Gulf of Cadiz. Besides the importance of these values for a better knowledge of the palaeoceanography and palaeoclimatology of Atlantic Iberia, from now on archaeologists can set up reliable chronologies for Late Neolithic and Chalcolithic contexts using marine shell samples of that origin for radiocarbon dating.  相似文献

Archaeological surface finds are difficult to date. There are several useful methods, but each requires special circumstances and has one drawback or another. On the west coast of South Africa marine shell are abundant on surface sites but they are rarely dated because they are perceived to be in disturbed context and in questionable association with artefacts. This paper attempts to rectify this misconception and shows that, although far from perfect, a large suite of surface dates can shed as much light as excavated data. On the Vredenburg Peninsula they help refute the hypothesis that two economically and culturally distinct populations shared this pre-colonial landscape since 2000 BP.  相似文献

馆藏壁画是博物馆藏品中一类特殊的文物。在馆藏大召寺壁画、陕西唐墓壁画等现状调查研究的基础上,本文分析馆藏壁画区别于原址壁画的特殊性,并提出针对馆藏壁画特点进行历史信息与现状调查的内容框架。强调壁画揭取历史、修复史、搬运史和保存环境等历史信息的调查对于认知壁画的重要性:壁画的现状调查包括本体调查和病害调查两部分,能够帮助保护工作者以科学的视角综合评价壁画保存现状。本文分别论述调查各个方面的意义、具体内容和方法。调查结果无疑对于制定保护修复方案具有重要意义,为合理实施保护修复提供科学依据,并为后续研究和档案记录提供基础信息。  相似文献

潮湿土遗址隔水防潮技术对比研究   总被引:3,自引:0,他引:3  
潮湿土遗址的破坏,很大程度上是受水的影响,目前国内几个潮湿土遗址经常使用的防水隔水措施主要有:挡水墙、隔水廊道、拱券法和抽水法。经过对几种方法进行总结评价,可看出拱券法是最有效的方法。  相似文献

金鸡岭遗址窑址群是目前长江中游发现的屈家岭文化时期数量最多、形制最丰富、分布最为集中的窑址群。陶窑从形态特征看有圆形窑、长条形分室窑、长方形馒头窑三种类型,其中长条形分室窑似龙窑结构在长江流域是首次发现,为我国早期龙窑的起源提供了极为重要的研究资料。窑址附近发现的非正常死亡的人骨架可能与窑址奠基或祭祀仪式有关。该窑址群时代为屈家岭文化时期。  相似文献
