摘要
锡水洞啮齿动物化石共6科19属25种.其中大部分为东洋界种类,因此具有强烈的南方色彩;喜湿热的现生啮齿类占绝对优势,它反映了一个气候相对湿热的时期,表明锡水洞遗址当时具有亚热带森林环境.该啮齿动物群的时代为中更新世;它既可与南方歌乐山期各动物群直接对比,又可与北方周口店第一地点动物群对比,因此在研究南北动物群对比上具有重要意义;它的时代比公王岭动物群的晚,比陈家窝动物群的可能也稍晚.
A number of larger mammalian fossils were found in association with many stone artifacts,bone tools and ash layers by Huang Chunchang in 1981 in the cave deposits of Xishuidong paleolithic site of Lantian,Shaanxi.The result of a preliminary study of the larger mammalian fossils by Professor Huang is that the fauna is considered to be a correlative of the Gongwangling fauna,that is to say,the age of the Xishuidong fauna is late Early Pleistocene,and is one that is found in a warm and wet forest climates.But the result of mord detailed study of the larger mammalian fossils by the authors of this paper is that the age of the fauna seems to be Middle Pleistocene,and there is not enough evidence to relate this fauna to the Gongwangling fauna.In order to determine the age of the Xishuidong fauna more exactly and to demonstrate the relationship between this fauna and the fauna of Gongwangling and of Chengjiawo,a large amount of micromammals were collected by screen-washing in 1993 from the same level of the same cave scdiments where the larger mammalian fossils and paleocultural rclics were found.This paper only deals with the materials of the rodents in the collections.
