Plant economy of hunter-gatherer groups at the end of the last Ice Age: plant macroremains from the cave of Santa Maira (Alacant, Spain) ca. 12000-9000 BP

摘要

Up till now, plant macroremains of hunter-gatherer groups at the end of the last Ice Age and the very early Holocene have very rarely been investigated on the Iberian Peninsula and elsewhere. The use of systematic recovery techniques at the archaeological cave site of Santa Maira has allowed the recovery of a large amount of plant remains (fruits, seeds and wood) from Upper Palaeolithic and Epipalaeolithic levels (12000-9000 B.P.) Charcoal analysis has allowed us to reconstruct the surrounding vegetation of the site. In the valley bottoms mesophilous woodland with Quercus was present even in the lowest layers (Upper Magdalenian) During the Late-glacial Juniperus was very important, in the early Holocene Quercus (both evergreen and deciduous) took over. Large numbers of macroremains of fruits (Quercus sp., Sorbus sp., Olea sp. and Vitis sp.) were found, but a significant quantity of legumes together with a few grass seeds have also been identified. This assemblage most probably represents the gathering of wild plant resources by the inhabitants of the cave, and allows us to reconstruct some of the food gathered from plant resources.
