Bout coupé handaxes are widely considered to be a cultural and typological marker for the Middle Palaeolithic in Britain, and are traditionally dated to around the end of the Last Interglacial or the beginning of the Devensian glaciation. Much debate has surrounded the typological validity of this form, but relatively little attention has been paid to the stratigraphical integrity of the sample. This paper takes a fresh look at the bout coupé problem using a select sample of better provenanced pieces and employs the most current chronological frameworks. We conclude that there is a temporally restricted bout coupé phenomenon in the British Isles, but contrary to previous claims these handaxes cannot be regarded as an unequivocal marker for the Mousterian and nor do they belong to the early Upper Pleistocene. Rather the bout coupé phenomenon marks the recolonization of Britain by Neanderthal populations during OIS 3 (59–41 ka). This further suggests a bipartite division of the British Middle Palaeolithic, each period having a quasi-distinctive lithic signature.  相似文献

The presence of processed birds in the archeological faunal record is considered key to assessing human dietary evolution. Taphonomic studies on birds from sites older than Marine Isotope Stage (MIS) 2 have become relevant in the last few years, leading to the proposal of more complex scenarios of human subsistence. Several works have demonstrated direct evidence of bird consumption by Homo prior to anatomically modern humans in Europe; however, others support the hypothesis of non-anthropogenic bird accumulations. This has led to the necessity of determining what elements or factors cause the human exploitation of birds in some archeological sites before the end of the Pleistocene. The Grotte des Barasses II site is located within this framework. Short-term human occupations have been attested by the presence of lithic tools and processed macrofaunal remains. Additionally, a small assemblage of bird bones has also been recovered. Here, we present a detailed taphonomic study with the aim of exploring possible relationships between these avian taxa and human occupations. Despite the fact that Neanderthals inhabited the cave, avian specimens show damage pointing to different causative agents. Direct evidence (digestion, gnawing) indicates that mammalian carnivores and nocturnal raptors were mainly involved in the accumulation of bird bones. We propose some factors that might determine whether or not small game was exploited in this specific locality and emphasize the importance of such analytical approaches in the general interpretations of the Pleistocene sites.  相似文献

A methodology for determining the relative technical efficiency of public decision making units is described. The methodology allows the identification of those units which are most efficient at converting physical inputs to physical outputs, and the calculation of the relative efficiency of less efficient units based on the results obtained by the most efficient. An illustration of the methodology is supplied using data from 469 municipal police agencies. Some policy suggestions based on the illustration are offered.  相似文献
