Exploratory Research and Survey into the Plio-Pleistocene Deposits of the Gona Paleoanthropological Research Project Area, afar, Ethiopia

这是一项在戈纳研究区进行考古调查的提议，目的是寻找世界上已知最古老的石器的制造者，并研究古代人类开始制造石器的原因。戈纳位于埃塞俄比亚的阿法尔地区，1992年至1994年期间在那里出土了3000多件石器。这些石器可以追溯到250万到260万年前，它们是由300万年前被称为“露西”的人类祖先化石的后代制造的。戈纳距离“露西”遗址约10英里，距离另一个被称为中阿瓦什的遗址约50英里，科学家最近在那里发现了距今近450万年的前人类祖先的骨骼化石。在戈纳人的工具上没有发现史前人类的骨骼化石，但有强有力的考古证据表明，它们是由可能是我们的直系祖先的史前人类制造的。戈纳项目的首席调查员组织了一个由来自美国、埃塞俄比亚、西班牙和南非的科学家组成的小组，继续进行调查和挖掘，寻找这些古代工具制造者的化石遗骸，在260万年以上的沉积物中寻找石器工具，并寻找带有石器切割痕迹的动物骨骼化石，作为食肉的直接证据。戈纳石器有锋利的刃口，它们可能是用来切动物尸体吃肉的刀。250万年前的戈纳工具与东非其他地方从近200万年的沉积物中挖掘出来的工具非常相似。戈纳人的工具制作精良，这表明260万年前的先人可能有一个制作和使用工具的悠久传统。项目考古学家将在沉积物中寻找石器的痕迹，这些沉积物甚至比20世纪90年代初发掘的还要古老。项目考古学家和骨骼专家将在1992年至1994年期间对所研究地区附近的矿藏进行广泛调查。该项目的地质学家将研究戈纳的土壤结构，并收集火山灰，以确定新地区石器和化石骨骼的年龄。测试挖掘将在几个地区开始，以取样石器和化石骨骼。这种采样策略对于研究史前人类在古戈纳景观不同部分进行的各种活动是有效的。该项目的总体目标是探索戈纳地区，寻找我们祖先制造工具的实际开端，寻找制造工具的祖先的化石遗骸，以及寻找工具使用行为和生存活动的考古证据。

This is a proposal to carry out archeological survey in the Gona Study Area to search for the makers of the world's oldest known stone tools, and to study why ancient humans began making stone implements. Gona is located in the Afar region of Ethiopia where more than 3,000 stone tools were excavated between 1992 and 1994. The stone tools are dated between 2.5 million and 2.6 million years, and they were made by thedescendants of the 3.0 million year old ancestral human fossil known as "Lucy." Gona is located about 10 miles from the "Lucy" site, and about 50 miles from another site known as Middle Awash where scientists recently discovered fossilized bones of prehuman ancestors dated close to 4.5 million years. There were no fossilized bones of prehumans found with the Gona tools, but there is strong archeological evidence that they were made by prehumans who are probably our direct ancestors. The Principal-Investigators of the Gona Project have organized a team of scientists from the U.S.A., Ethiopia, Spain and South Africa to continue survey and excavations to search for the fossilized remains of the makers of these ancient tools, to search for stone tools in deposits that are older than 2.6 million years, and to look for fossilized animal bones that bear stone tool cut-marks as direct evidence for meat-eating. The Gona stone tools have sharp cutting-edges and they were probably used as knives for cutting up animal carcasses for meat. The 2.5 million year old Gona tools are very similar to those excavated elsewhere in East Africa from deposits that are close to 2.0 million years. The Gona tools were well-made and this suggests a possible long tool-making and tool-using tradition by prehumans prior to 2.6 million years ago. Project archaeologists will look for traces of stone tools in the deposits that are even older than those excavated in theearly 1990s. Extensive survey will be conducted by Project archaeologists and bone specialists in the deposits adjacent to the areas studied between 1992 and 1994. The Project geologists will study the soil formations at Gona and collect volcanic ashes to determine the age of stone tools and fossil bones from new areas. Test-excavations will be opened at several areas to sample stone tools and fossil bones. Such a strategy of sampling is effective to study the various activities conducted by prehumans atdifferent parts of the ancient Gona landscape. The overall goal of this Project will be to explore the Gona region for the actual beginnings of tool-making by our ancestors, for fossil remains of the tool-making ancestors and for archaeological evidence of tool-using behaviors and subsistence activities.
