Aterian stone tools represent one of the clearest indications of technological regionalisation in the North African Middle Stone Age. Found in association with Homo sapiens skeletal remains and more recently with symbolic material culture, the Aterian is widely thought to reflect modern human identity and cognition. As a lithic industry, the Aterian has been primarily defined by the presence of stemmed or tanged tools, but there has been little quantitative study of the relationship between tangs and other forms of hafting modifications, such as shouldering and basal thinning. Understanding the diversity of these features and their relationships with one another will clarify the organisation and adaptations of North African populations during Marine Isotope Stage 5 (MIS 5, ∼130–70,000 years ago), a critical timespan for modern human dispersal. This paper presents the results of a stepped analysis of fifteen Aterian and other non-Aterian assemblages from the same spatial and temporal bracket in North Africa. Using Correspondence Analyses together with a suite of other statistics, the results indicate that tanging represents a widely applied strategy of hafting a variety of different tools. On the other hand, basal thinning is specifically correlated with lightweight, highly retouched points. The distribution of these features appears to reflect geographical proximity and shared environments, rather than articulating with traditional named industries. This in turn suggests that a continued focus on tangs to differentiate an ‘Aterian’ from other, contemporary North African MSA industries may be obfuscating regional-scale patterns of technological diversity.  相似文献

This paper reflects on fieldwork undertaken at youth-led community radio station, KCC Live. It draws on Goffman to elucidate the differences between front and backstage spaces at KCC Live, and provides snapshots from research encounters to illustrate the importance of observant participation (over participant observation) in permitting access to these spaces. This paper celebrates the embeddedness of the researcher as a member of the community under study. In doing so, it argues that immersion in community research settings can enable insight into the functioning, relationships, rules and peculiarities of the place and people, all of which are fundamental to ethnographic research.  相似文献

Breccias in the upper Sterkfontein cave system levels have yielded artifact assemblages as well as Homo and Australopithecus africanus remains. As mapped by the author, this sytem can be subdivided into a northern sector, comprising small, bedding-controlled passageways, and a southern one with large galleries controlled by subvertical fracture zones and partly filled with two generations of external, detrital sediment. A four-stage model describes the development of these deposits. The implications of this study include: (1) The caves formed in one rather than two phases, as a result of structural rather than watertable controls. (2) The lowest strata of both depositional generations, 50–60 m below the hillcrest are probably the oldest. T. C. Partridge's Sterkfontein Formation only includes approximately the upper half of the stratigraphic column recognized here. Deposits underlying those he described are also fossiliferous and probably substantially older than the 2·8+ million year age attributed to the lower units of the Sterkfontein Formation. (3) The Sterkfontein Formation, as defined by Partridge, is a composite stratotype, comprising one surface exposure and another underground, at mid to upper levels in the system. Their stratigraphic relationships are obscure and since the lower boundary of the Formation also is in doubt, erection of a formal stratotype is premature. Deep-lying breccias may ultimately warrant another component, extending the Sterkfontein Formation to the lowest known levels of the cave system.  相似文献
