Estimating Core Number in Assemblages: Core Movement and Mobility During the Holocene of the Fayum, Egypt

摘要: The utility of the cortex ratio first developed by Dibble et al. (American Antiquity, 70(3), 545–560, 2005) and extended Douglass 73(3), 513–526, 2008) is examined in contexts where cores rather than flakes may be transported. used to demonstrate movement artifacts quantifying missing surface area, typically it that were removed left behind. In such situations, removal with small volumes will result relatively large cortical areas resulting a low ratio. However, when removed, assemblages lose greater proportions artifact volume relative loss area. Here, we propose methods investigate effects high-volume from archeological as proxy for human addition We apply stone Fayum, Egypt, changes mid-Holocene mobility are closely linked food production.
