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.

目前的研究主要集中在孔索古人类学的实地研究和实验室分析其地质，古生物和考古材料。对韦托地区的古人类学和最近从埃塞俄比亚其他遗址发现的原始人类遗骸进行了更有限的研究。我们关于Konso站点的主要结果总结如下。建立了整个研究区的年代地层格架，特别是对核心研究区的地层学、年代学和沉积学进行了详细的描述。系统地收集了3000多个古生物标本，并对7500多个哺乳动物遗骸的整个动物群组合进行了策划和分类学评估。我们现在有一个可靠的表征丰富的孔索动物群从大约1.4和1.9百万年的水平。这些动物群在许多方面与东非已知的时间相当的动物群不同，将在不久的将来进一步评估。发现了7个原始人类标本。我们将我们的形态分析集中在A.boisei遗骸上，其结果已经发表。本研究的考古学计划侧重于评估Konso石器技术的时间侵入趋势。一个原始面貌的早期阿舍利组合被证实首先出现在170万年的水平，随后是广泛的和更多变的早期阿舍利组合在150万至140万年，最后导致一个更精致的典型阿舍利技术在估计年龄小于130万年。
