三峡库区池坝岭旧石器遗址2007年发掘简报

A Preliminary Report on the Excavation of the Chibaling Paleolithic Site in the Three Gorges Region

池坝岭遗址位于三峡库区重庆市丰都县境内,埋藏于长江左岸第三级基座阶地内。2007年,该遗址经过首次抢救性发掘,发掘面积514m2,出土石制品213件。石制品原料系就地取材于河流阶地底部的河卵石;石制品类型包括石核、石片、石器和断块等;硬锤锤击法为剥片的基本方法;石器以大型为主,毛坯多为完整石片和石核,刮削器和砍砸器是主要类型;石器由硬锤直接加工而成且加工简单,方向以正向居多,加工部位多集中在单端或单边。石器工业面貌除具有中国南方旧石器时代主工业鲜明特点外,石片和石片石器也占较大比例,尤其是摔碰法的存在对探讨旧石器时代三峡地区和西南地区石器工业的关系提供了新的材料和线索。依地貌地层对比和已有的测年数据推断,池坝岭遗址的时代为中更新世晚期。

The Chibaling Paleolithic site, buried in the third terrace of the left bank of the Yangtze River in the Guanshitan village, Zhenjiang town, Fengdu County, Chongqing, was excavated from November to December, 2007 by the staff of Institute of Vertebrate Paleontology and Paleoanthropology （Chinese Academy of Sciences ）, as part of the salvage archeological project in the Three Gorges Region. 514 m^2 was exposed during the excativions.
