广西都安九■山人类化石与共生动物群及其在岩溶发育史上的意义

<正> 概况九■山属广西都安县地苏公社东风大队,位于县城西北约12公里处(图1)。1977年11月,成都地质学院水文地质二队在九(?)山的R5013洞内发现了四枚人类牙齿化石和一些脊椎动物化石。1978年1月,广西博物馆在同一洞穴内进行发掘,又获得不少化石。九(?)山位于东风坡立谷内,R5013洞(图2)的洞口底部高出谷底9.5米,海拔约166.5米高。洞口朝向正东。溶洞全长约55米,包含一大一小两个洞室,略呈葫芦形。该

HUMAN FOSSILS AND ASSOCIATED FAUNA OF JIULENGSHAN HILL,GUANGXI

The four teeth of Homo sapiens sapiens and a number of vertebrate fossils described here were discovered in the R5013 cave of Jiulengshan Hill, Duan County, Guangxi. The human deciduous molar retains a few primitive characters, while the permanent ones do not differ from recent humans. The vertebrate fossils are composed of at least 35 species representing 31 genera. Most of them are members of the classical Ailuropoda-Stegodon Fauna. Jiulengshan fauna may be dated to a later stage of the Upper Pleistocene.A branch of Hongshuihe River flows near Jiulengshan Hill. Terrace 2 of Hongshuihe River and its branches corresponds with the level of the cave floor in relative height. Therefore, this terrace should be similar to the cave deposits in geological age. This is of some significance in regard to the research of the history of development for the local Karst.
