项目摘要

The present study primarily focussed on paleoanthropological field research at Konso and laboratory anaylses of its geological, paleontological and archeologcial materials. More limited research was undertaken regarding the paleoanthropology of the Weyto region, and of hominid remains recently recovered from other sites in Ethiopia. Our main results regarding the Konso sites are summarized as follows. The chronostratigraphic framework of the entire study area was established, especially with detailed accounts of the stratigraphy, chronology, and sedimentology of the core research area. Over 3000 paleontological specimens were systematically collected, and the entire faunal assemblage of over 7500 mammalian remains have been curated and taxonomically evaluated. We now have a reliable characterization of the abundant Konso fauna from the circa 1.4 and 1.9 myr levels. These fauna are distinct from known time-equivalents of eastern Africa in many ways, and will be further evaluated in the near future. Seven hominid specimens were recovered. We focussed our morphological analyses on the A.boisei remains, the results of which have been published. The archeological program of the present study focussed on evaluating the time-transgressive trends in lithic technology at Konso. An early Acheulean assemblage of primitive aspect was confirmed to first occur at the 1.7 myr level, followed by extensive and more varaiable early Acheulean assemblages at 1.5 to 1.4 myr, finally leading to a more refined typical Acheulean technology at an estimated age of younger than 1.3 myr.

本研究主要集中在Konso的古人类学领域研究以及其地质，古生物学和考古材料的实验室Anaylses。关于Weyto地区的古人类学进行了更多的研究，最近从埃塞俄比亚的其他地点回收了人类人类学。我们关于KONSO站点的主要结果总结如下。建立了整个研究领域的年度地层学框架，尤其是关于核心研究领域的地层学，年表和沉积学的详细说明。系统地收集了超过3000个古生物学标本，并且已经策划了7500多名哺乳动物遗体的整个动物组合。现在，我们对大约1.4和1.9 MYR水平的丰富Konso动物群的可靠表征可靠。这些动物区系在许多方面与东非的已知时间相等不同，并将在不久的将来进行进一步评估。回收了七个人类标本。我们将形态学分析重点放在a.boisei遗骸上，结果已发表。本研究的考古计划的重点是评估Konso岩性技术的时间推荐趋势。早期的原始方面的Acheulean组合已证实在1.7 MYR水平上首次发生，然后在1.5至1.4 Myr处进行广泛而更可变的早期Acheulean组合，最终导致更精致的典型的Acheulean技术在年龄较小的年龄较大的年龄较大。
