Geochronological and Paleoecological Context of the late Acheulean at Mieso, Ethiopia

埃塞俄比亚米埃索遗址记录了一个可能年轻至约212ka的经典阿舍利期岩屑组合的持久性。然而，Mieso的地质年代学是不确定的，该地区挖掘出的动物从未被描述过。鉴于记录人类进化转变的技术和古生态背景的重要性，以及关于非洲动物群中更新世至晚更新世演化的信息匮乏，我们在此请求支持1)重新访问Mieso遗址，利用OSL和ESR方法进行新的地质年代学分析，以及2)研究和分析Mieso动物群及其古生态背景。

The site of Mieso, Ethiopia, records the persistence of a classic Acheulean lithic assemblage that may be as young as ~212 ka. The geochronology at Mieso is, however uncertain and the fauna unearthed from excavations in the area has never been described. Given the importance of documenting the technological and paleoecological context of transitions in human evolution, and the paucity of information on the mid to late Pleistocene evolution of African faunas, we here request support to 1) revisit the Mieso site to collect samples and conduct new geochronological analyses using OSL and ESR methods, and 2) to study and analyze the Mieso fauna and its paleoecological context.
