郧县人遗址发现的石制品

THE STONE ARTIFACTS FROM THE YUNXIAN MAN SITE

本文记述了湖北省郧县曲远河口郧县人遗址发现的石制品。这一石工业显示出如下特点：打片以锤击法为主，存在砸击的石锤，表明可能使用砸击法；未见系统修理台面的石片，但存在有疤台面和多疤台面的石核；砾石石器居多数。在采集的标本中有零台面石片；有两面加工的带尖的砾石石器，其中一件使人联想到加工未完的手斧。伴出的哺乳动物化石显示出南北混合的过渡地区的特色，第三纪残留种和早更新世代表种类的存在表明其时代属早更新世晚期，大致和公王岭蓝田人时代相当。

The present article deals with the stone artifacts from the Yunxian Man site at Quyuanhekou, in Yunxian county, Hubei province. The stone industry is characterized by: 1) free hand hammering method predominates in flaking, 2) the presence of pitted pebble or cobble indicates the possibility of using the bipolar technique; 3) no systematic preparation can be observed on the talons of flakes, but there are a few cores with faceted platform or multifaceted platform; 4)the pebble or cobble tools predominate in the tool combination; 5)choppers and chopping tools are main types. There are bifacially worked pointed cobble tools in the collected specimens, one of them is reminiscent of partial hand-ax. In addition a scraper made on a flake with a null striking platform ( talon nul ) was found in the collected specimens. The associated mammalian fossils show a mixed trait of both north and south faunas of the transitional region in China. The presence of Tertiary survival and typical Early Pleistocene forms demonstrates the age of Yunxian Man may be referred to the late Early Pleistocene, by and large corresponding to that of Lantian Man at Gongwangling, Lantian in Shaanxi province.
