Grass silica short cell phytoliths were sampled from the four lowermost archaeological strata in excavation 1 at Wonderwerk Cave and offer an independent record of climatic change during an episode of Early Stone Age hominin occupation at the cave. Linked to differences in growing season temperature and the geographic distribution of C3 and C4 grasses in southern Africa, fossil grass phytoliths were used to trace palaeoenvironmental shifts at the site. The results suggest that Early Pleistocene environmental conditions at the cave fluctuated: between wetter and drier summer–rainfall growing conditions (C4) towards the end of the Olduvai subchron and the beginning of the subsequent interval of reversed polarity, to mostly dry and cooler winter–rainfall growing conditions (C3), that continued throughout the interval. It ended with a shift towards increased summer rainfall aridity at around one million years ago. The fluctuation between markedly wetter and drier C4 conditions at the cave (NADP-me grass types vs. NAD-me grass types) does not support the premise that the expansion of C4 grasslands was always coupled with increased aridity.  相似文献

The discovery of Kef en-Naga site, an open-air human occupation in northeastern Algeria, was favored by a sandstone quarrying where work truncated much of the archaeological sequence on its cross-section. A multidisciplinary rescue excavation conducted on this site provided, for the first time in the region, the evidence of superimposition of two stratigraphic levels (lower and upper) of sandy clay deposits formed in humid paleoenvironmental conditions. Besides, XRD analysis show that a large amount of hematite (Fe2O3) is localized at the lower level of the stratigraphic section, where iron is found in oxide form due to the moisture. As for rock magnetic property characterization analysis, the various magnetic parameters have strong values in the upper level, and the grains are small-sized. However, various magnetic parameters are lower at the lower level and the magnetic grain concentration is reduced. Although the site is lacking faunal and carpological remains, thereby depriving us of reliable dates, the two stratigraphic levels are correlated to the Holocene according to archaeological and paleoenvironmental considerations. The lower level likely corresponding to an early Epipaleolithic culture marked by the production of microliths using a microburin blow technique, while the upper level is related to a subsequent Epipaleolithic phase, characterized by the disappearance of microburin blow technique, the dominance of an industry on flakes and the existence of pressure debitage.  相似文献

Logging related sites and features are relatively common in forested areas of the western United States. Such sites are typically investigated through site mapping and artifact recording, and if possible, oral history. We present the results of a dendroarchaeological investigation of a small-scale unauthorized logging site in western New Mexico, US. The results provide information on the economic and social forces that created the site, as well as the scale of activities conducted there. We suggest that individuals quickly responded to improved lumber market conditions and changes in public land administration to exploit what had been an economically marginal timber stand.  相似文献

Archaeologically based explorations of colonialism or institutions are common case-studies in global historical archaeology, but the “colonial institution”—the role of institutions as operatives of colonialism—has often been neglected. In this thematic edition we argue that in order to fully understand the interconnected, global world one must explicitly dissect the colonial institution as an entwined, dual manifestation that is central to understanding both power and power relations in the modern world. Following Ann Laura Stoler, we have selected case studies from the Australia, Europe, UK and the USA which reveal that the study of colonial institutions should not be limited to the functional life of these institutions—or solely those that take the form of monumental architecture—but should include the long shadow of “imperial debris” (Stoler 2008) and immaterial institutions.  相似文献

Established as a British imperial penal colony, Van Diemen’s Land received approximately 75,000 convicts before cessation of convict transportation in 1853. A vast network of penal stations and institutions were created to accommodate, employ, administer, and discipline these exiled felons. Popular interpretations of Australia’s convict past highlight dynamics of shame, avoidance and active obliteration that characterized Australia’s relationship to its recent convict past. Yet, closer examination of these colonial institutions suggests a far more ambivalent relationship with this “dark heritage,” evidenced by continuous tourism and visitation to these places of pain and shame from the mid-nineteenth century to the present.  相似文献

Australia’s quarantine regulations have their roots in colonial practice. This paper is concerned with the “matter” of quarantine—its location, spatialization, and materialization—and the ways in which it contributed to the colonial agenda. Through an exploration of Sydney’s North Head Quarantine Station, quarantine is shown to be a technology through which the colony and the continent were framed as simultaneously pure and vulnerable. These colonial roots of quarantine practice are then brought back to the present, drawing on Stoler’s (2008) concept of “imperial debris” to contemplate the contemporary ruins, both material and ideological, of colonial quarantine practice.  相似文献

In 2011, during a salvage excavation at the Fort York National Historic Site, Archaeological Services Inc. (ASI) recovered a pinfire shotgun shell cartridge. This unique small find tells a story of the ebb and flow of the firearms technology used by armed forces around the world. It also shows how the pinfire shotgun was likely brought to Fort York in response to the Trent Affair. This international incident during the American Civil War risked a return to hostilities between Britain and the United States and sparked a defensive rearmament across the colony of Canada. This artifact also highlights the military evolution of the shotgun from a hunting tool brought to the battlefield by ragtag militia, to cutting edge weaponry used by military special forces around the world.  相似文献

This paper examines the nineteenth- and twentieth-century non-indigenous presence in the Solomon Islands as an example of a maritime industrial frontier. In particular it employs a combination of frontier and maritime cultural landscape theories to consider the material and cognitive elements that inform us about how a maritime industrial frontier was shaped and operated, including the relationships between shipwrecks, maritime infrastructure, nodal points of activity and indigenous agency. The integrated analysis of these elements reveals distinct maritime patterns considered indicative of the broader economic, political and social concerns occurring on this frontier on the peripheries of the Western European World System.  相似文献
