Crown height measurements are used to establish age distributions for several species of larger bovids represented in faunal samples from the Middle Stone Age (earlier Upper Pleistocene) deposits of the Klasies River Mouth Caves and the Later Stone Age (later Upper Pleistocene/Holocene) deposits of Nelson Bay Cave, South Africa. There are no obvious differences between the sites in the age distributions of the species they share, but there are significant differences in age distributions among species. Two basic patterns are apparent. In the first, characterizing the blue antelope (Hippotragus leucophaeus), roan antelope (Hippotragus equinus), Cape buffalo (Syncerus caffer), and giant buffalo (Pelorovis antiquus), the archaeological samples contain numerous very young animals and relatively few prime-age adults. At least in the buffalo samples, there is also a fair representation of old adults. In the second pattern, characterizing the bastard hartebeest (Damaliscus dorcas or D. niro) and especially of the eland (Taurotragus oryx), prime adults are far more prominent relative to younger and older age groups. The first pattern is similar to the natural pattern of attritional mortality that probably characterizes all healthy, stable populations of free-ranging large ungulates, while the second is more reminiscent of the age structure of live herds. The first pattern may reflect hunting focused on individual animals, particularly those whose age made them most vulnerable, while the second may reflect the susceptibility of certain species to driving, so that whole groups could be killed in traps in which differences in age had no meaning. 相似文献

The early Late Pleistocene late archaic human remains from Xujiayao, northern China, reveal several abnormalities of the neurocranial vault. The Xujiayao site is located on the northwestern boundary of the Nihewan Basin, and on the basis of various indicators, it dates to the early Late Pleistocene. Among the 15 human neurocranial elements found at Xujiayao in the 1970s, three elements show minor traumatic lesions of the external table: the largely complete Xujiayao 5a immature parietal bone, the Xujiayao 8 small piece of anterior right parietal bone and the Xujiayao 12 partial occipital bone. The lesions are all superior to the temporal or nuchal lines and hence were subcutaneous, covered only by the pericranium, the galea aponeurotica and the overlying skin. The external tables are variably concave with irregular bone within the bony depressions, and the diploë show varying degrees of involvement. The Xujiayao abnormalities join a series of minor neurocranial healed lesions among Pleistocene humans, as well as more pronounced healed neurocranial and facial trauma.
