Limb bones of Mute Swan Cygnus olor from neolithic to bronze age Cambridgeshire peat were larger than those of a recent sample when compared biometrically. The decrease in overall size that this may indicate could be part of an evolutionary trend.  相似文献

The discovery of two new Frasnian species of the subfamily Asteropyginae, Bradocryphaeus kermanensis and Radiopyge hamedii, in the Haruz section north of Kerman, east-central Iran, demonstrates for the first time the presence of North Gondwanan trilobites in this region. The two new species provide a link between faunas from Afghanistan to the east and the Alborz Mountains in north Iran. The recognition of R. hamedii confirms the validity of Radiopyge Farsan, hitherto known only from Afghanistan, as well as the presence in some Frasnian Asteropyginae of six pairs of lateral pygidial spines.  相似文献

The Early Cretaceous Otway and Strzelecki Groups exposed on the southern coast of Victoria, Australia, have produced a fauna of dinosaurs that lived within the Antarctic Circle. As many as five or six species of hypsilophodontids numerically dominate the collections from there, but the rarer and more fragmentary theropod remains suggest a surprising diversity of carnivorous dinosaurs. A possible surangular and an isolated vertebra have characters considered diagnostic for Late Cretaceous oviraptorosaurs of the Northern Hemisphere. Other fossils suggest the presence of ornithomimosaurs, dromaeosaurids and neoceratopsians, and with the possible oviraptorosaur remains, challenge the widespread assumption that these animals originated on the northern continents.  相似文献

The mesolithic of Western Europe   总被引:4,自引:0,他引:4  
Recent investigations of prefarming adaptations during the Mesolithic period in early Holocene Europe have led to significant revision of traditional views. A number of innovations and changes occur, particularly toward the end of the Mesolithic, that permit this time to be described as both dynamic and extraordinary. Permanent settlement and the use of domesticated animals, exchange, and, perhaps, cultivated plants and monumental tombs characterize a number of later Mesolithic adaptations. The transition to the Neolithic is now regarded as the result of in situ developments in most areas of Western Europe, as Mesolithic groups slowly adopted pottery, cultigens, and other characteristics of farming villagers. In this paper, questions regarding chronology, nomenclature, and the definition of terms are addressed initially. Changes in European environments at the close of the Pleistocene and during the early postglacial are considered in terms of major impacts on human adaptation. The central focus of this study is a survey of the Mesolithic in Ireland, Britain, the Netherlands, Belgium, France, Portugal, Spain, and Italy. Recent research projects in these areas are discussed in terms of new approaches and results. An overview of developments in these countries is also presented, emphasizing the transitions from the Paleolithic and into the Neolithic. Concluding remarks address future directions in Mesolithic research.  相似文献

West Tump is a Neolithic chambered tomb originally excavated in 1880. The mound was found to contain a mixed skeletal assemblage, the majority of which was disarticulated. Between 2000 and 2001 material from the site including human bone was re‐examined with a portion of this project focused on taphonomic evidence observed on the human skeletal material. Amongst the factors selected for investigation were deliberate toolmarks. Three specimens were identified as exhibiting toolmarks. Analysis demonstrated that the observed features were cutmarks, consistent with the use of flint tools. However those on two of the specimens were found to be both post‐mortem and recent. The cutmarks observed on the remaining specimen, a right clavicle, were identified as having been inflicted during the peri‐mortem period and consistent with decapitation. British Neolithic mortuary practice has been the subject of ongoing debate since the earliest excavations of relevant sites, but until very recently few assemblages from such contexts have been re‐examined and much of the data in use has derived from sources of considerable age and questionable reliability. The selective removal of specific skeletal elements (particularly skulls) has repeatedly been described in the literature regarding the collective funerary monuments of this period. It has often been assumed that such practices took place after the soft tissues had decayed. One of the examples discussed, suggests this may not always have been the case and the potential significance of this finding is discussed in addition to a possible interpretation of the cutmarks seen on the remaining specimens.

吴江梅堰龙南新石器时代村落遗址第三、四次发掘简报   总被引:3,自引:2,他引:1  
吴江梅堰龙南遗址第三、四次发掘所出土的器物表现出明显的良渚文化晚期特征,极大地丰富了该遗址的分期资料。第三、四次发掘所发现的以木桩为基础的干阑式房址与该遗址以往发现的浅穴或半地穴式的建筑风格迥异,反映了水网地区原始先民为适应环境在居住形式上的多样性。  相似文献

论黄河流域前期新石器文化的文化特征和时代特征   总被引:1,自引:0,他引:1  
70年代以来,在黄河流域陆续发现的几支前期新石器文化,曾在学术界引起热烈讨论。本文通过对每个文化的分布区域及文化特征的具体分析,阐明了它们相互之间的纵横关系,认为它们是各自相对独立的文化实体。  相似文献

江淮东部是介于海岱地区和太湖地区之间的一个重要的考古学文化区。自50年代初在江淮东部发现淮安青莲岗遗址并由此提出青莲岗文化的命名以来,江淮地区的考古工作始终受到考古学界的高度关注。而高邮龙虬庄遗址被评为1993年中国十大考古新发现之后,在考古学界也产生了较大的影响。围绕龙虬庄遗址的考古发现,探讨江淮东部原始文化和青莲岗文化,以及淮河流域古文化,对于推动中国考古学研究向纵深发展,有着积极的意义。在高邮召开的龙虬庄遗址与江淮地区古文化的座谈会上,来自北京和苏鲁豫皖浙的专家各抒己见,本刊将座谈会上有代表性的专家的发言经整理后以纪要的形式刊出,旨在对江苏乃至淮河流域的考古工作起到积极的推动作用。  相似文献

清末民初盛行通过日译本转译西方著作,汉语中引进了大量的日语词汇和句法。笔者认为,比起一直以来通用的“欧化”的说法,把此现象称为“日化”更为贴切。本文以鲁迅作品中的具体“日化”语言实例为证,论证了“日化”的语言事实。对于“日化”语言一直以来遭忽视的现象,笔者从政治、经济、文化心理、汉字等方面分析了原因。  相似文献

The two type-sites of the Khartoum Mesolithic and Khartoum Neolithic (Khartoum Hospital and Shaheinab), in Central Sudan, were excavated at the end of the 1950s. The ceramics recovered from these sites, characterized by wavy line and dotted wavy line decoration, formed a cornerstone for identifying Mesolithic–Neolithic components along the Central Nile and across the Sahara-Sahel Belt. Moreover, they formed a model for an evolutionary sequence, and suggested a level of cultural uniformity for the Nilo-Sahara-Sahel Belt from the eighth to the fourth millennia BC. This paper examines these and other related issues.L'hôpital de Khartoum et Shaheinab, qui se situe au centre du Soudan, sont les deux sites archéologiques principaux de la civilisation mésolithique et néolithique. Ces deux sites furent découverts et excavés au cours des années 1950s. Les céramiques découvertes dans ces deux sites se caractérisent par leurs lignes continues et ondoyantes, et d'autres ondoyantes mais discontinues. Ces céramiques représentent la pierre angulaire pour les caractéristiques de la période mésolithiqueet néolithique dans le centre de la vallée du Nile et á travers la zone du Sahara-Sahel. De plus, elles ont constitué un modèle pour l'évolution et ont suggéré une certaine uniformité culturelle entre la vallée du Nile, le Sahara et le Sahel de huitième au quatrième millénaires avant J.-C. Cette recherche traite donc de ces points et d'autres aspects s'y rapportant.  相似文献
