| Abstract: | Damiao of Wushan,Sichuan is a new important Homo fossil site discovered by Prof.Huang Wanpo.This fossil strata belong to the Lower Pleistocene and are about 18m inthickness.100 samples were collected at 15—30cm intervals vertically.Polarity after thermaldemagnetization is mainly in reversal,also with some innormal.They are corresponding to theOlduvai and Reunion Normal Polarity Subchrons of Matuyama Reversed Chron.And the stra-ta bearing Homo fossils are corresponding to the Reunion I Polarity Subchron.Its age is2.04—2.01 Ma B.P.It is the earliest Homo fossils discovered so far in China.Our researchresult also indicated that the lower boundary of Quaternary in China is not at the beginningof Olduvai Normal Polarity Subchron,but is at least 2 Ma old. |
