This article presents the results of the anatomical identification of wood charcoal from pre-Still Bay, Still Bay and Howiesons Poort assemblages at Diepkloof Rock Shelter (South Africa) using scanning electron microscopy. In the earliest phases, with pre-Still Bay stone tools, the charcoal shows a predominance of Afromontane forest taxa, some riverine woodland species, mesic thicket and proteoid fynbos vegetation. With a change in lithic technology in Still Bay contexts, the balance of Afromontane and thicket taxa shifts towards favouring the latter. A more diverse array of proteoid fynbos species emerges, and there is evidence for the use of plants from the local wetlands of the Verlorenvlei. In Howiesons Poort contexts, typified by a different lithic technology, the charcoal shows some Afromontane forest persisting, but the overwhelming change is towards greater species diversity, with the woody taxa being increasingly representative of thicket and shrubland. Some of the fynbos and thicket species are typical of vegetational communities which inhabit well-drained soils, rocky or dry locations at the present day. More wetland plants from the Verlorenvlei were selected for use. 相似文献

This paper presents the first multidisciplinary synthesis of the Middle Stone Age sequence of Diepkloof Rock Shelter (South Africa). We explore the main cultural changes that characterized southern African hunter–gatherer societies from OIS 5 to the beginning of OIS 3. We discuss the tempo of these changes, test the current interpretative hypotheses and explore an empirical model to explain the early appearance of symbolic marking within the Pleistocene hunter–gather societies of southern Africa. 相似文献

The three previous papers in this series Grigson, 1974, Grigson, 1975, Grigson, 1976 were a study of the basic craniology of the genus Bos using B. taurus as an example. This paper deals with B. primigenius from Holocene deposits in northern Europe, studying the relationship of absolute size, cranial proportions, angles and non-measurable characters to age and sex. It concludes that the two size forms of B. primigenius are merely the expression of sexual dimorphism, that the two forms B. primigenius and B. taurus are so similar that they form a continuum and should be considered to be of the same taxon, and that where B. taurus does differ from B. primigenius the differences can usually be ascribed to breed and can be described as specializations. 相似文献

When prehistoric archaeological sites yield non-carbonised wood, one of the ways to test for management practices consisting of pollarding and coppicing is analysis of branch diameter and age. However, the interpretation of such data is often based on assumptions. To test whether it is in fact possible to identify past woodland management on the basis of age/diameter analysis in archaeological wood assemblages, this paper presents models that predict the expected age and diameter distribution of branches from unmanaged and managed trees. The models have been tested using data on modern-day Alnus glutinosa, Fraxinus excelsior and species of the genus Salix. Branches of modern-day unmanaged and managed trees with a diameter up to approx. 2 cm (not an absolute limit) have a comparable age. Branches with a diameter of approx. 2–6 cm from unmanaged trees are older than similar branches from managed trees. The age distribution in the latter also ends abruptly. The age/diameter data from the modern-day trees indicate that the models can be used to discern management in the past, if branches up to approx. 2 cm in diameter are avoided and if, critically, taxon, sample size, growing conditions, natural disturbance/opportunistic wood collection and the possibility of diameter selection are taken into account. Archaeological datasets mainly from prehistoric sites are then reinterpreted by means of comparison with the models. Indications of management in prehistory as demonstrated by age/diameter are scarce but available. There is thus a clear need for further research in this field. Practical suggestions are provided for improving the quality of future research on woodland management practices by means of branch age/diameter analysis. 相似文献
