米索河谷是位于埃塞俄比亚中东部的一个新的古人类序列。它包含中更新世和上更新世沉积，化石和岩屑组合在层状沉积中。本文介绍了中更新世考古序列，归属于阿舍利晚期。人工制品的低密度集群表明阿舍利人对景观的短期使用。在Mieso 31中，其中一个挖掘的组合，改装集表明还原序列的碎片化，并使研究双面制造的初始阶段成为可能。Mieso 7也是一个分层的场地，主要特点是标准化的切割器集中，描绘了阿舍利技术的另一个方面，即与大型切割工具的使用和丢弃的最后阶段有关。可用的放射性测定日期将Mieso Acheulean大约在212 ka（数千年）前，这将使这一序列成为东非Acheulean的最新证据之一，在该地区已经记录了中石器时代的时间跨度。(C)2014爱思唯尔有限公司版权所有。
The Mieso valley is a new paleoanthropological sequence located in East-Central Ethiopia. It contains Middle and Upper Pleistocene deposits with fossil and lithic assemblages in stratified deposits. This paper introduces the Middle Pleistocene archaeological sequence, attributed to the late Acheulean. Low density clusters of artefacts suggest short-term use of the landscape by Acheulean hominins. In Mieso 31, one of the excavated assemblages, refit sets indicate fragmentation of the reduction sequences and enable study of the initial stages of biface manufacture. Mieso 7, also a stratified site, is primarily characterized by a small concentration of standardized cleavers, and portrays another dimension of Acheulean technology, that related to final stages of use and discard of large cutting tools. Available radiometric dates place the Mieso Acheulean around 212 ka (thousands of years) ago, which would make this sequence among the latest evidence of the Acheulean in East Africa, in a time span when the Middle Stone Age is already documented in the region.
