“元谋人”时代刍议

DISCUSSION ON THE AGE OF THE “YUANMOU MAN”(HOMO ERECTUS YUANMOUENSIS)

从古地磁剖面、地层的沉积速度及哺乳动物群性质三方面出发 ,讨论了“元谋人”的时代。通过古地磁剖面的对比 ,认为“元谋人”的层位应位于贾拉米洛亚时和后贾拉米洛亚时之间。“元谋人”动物群中含有不少的早更新世中、晚期分子和中更新世分子 ,其特点可与公王岭动物群对比。动物群中虽然出现了华北地区新第三纪的动物 ,但也显得进步 。

This paper deals with the age of the fossil human—“Yuanmou man”( Homo erectus yuanmouensis )based on the paleomagnetic polarity sections,sedimentary speed of the Yuanmou Formation and mammalian fauna.By correlation of the paleomagnetic polarity sections from the Yuanmou basin with Cox's and Mankinen's magnetic polarity time scales,the age of the “Yuanmou man” is late Early Pleistocene,that is between the Jaramillo event and late Jaramillo event.In the “Yuanmou man” fauna,there are some fossil mammals of middle and late Early Pleistocene,and of Middle Pleistocene although a fewer animals that lived in North China during Neogene and Early Pleistocene occurred in the local fauna.This assemblage of the “Yuanmou man” is correlated with the late Early Pleistocene Gongwangling fauna from Lantian County in Shanxi Province.
