新生代:
1.古近紀(jì)(Paleogene)大約距今6500萬(wàn)年,結(jié)束于23.03±0.05M,延續(xù)了約4247萬(wàn)年,哺乳動(dòng)物演化時(shí)代。

3.第四紀(jì)(人類起源,原始部落形成)(Quaternary Period)距今約160萬(wàn)年,人類出世并迅速發(fā)展時(shí)代,人類的發(fā)展經(jīng)歷了以下主要階段:
1)早期猿人階段(2百萬(wàn)年-1百75萬(wàn)年前):能人(Homo hails)在東非坦桑尼亞出現(xiàn),這可能是早期的直立猿人(Homo erectus);
2)晚期猿人階段(1百萬(wàn)年前):直立猿人(homo erectus)從非洲**到中國(guó)、爪哇,最著名的代表是北京猿人和爪哇猿人;
3)早期智人階段(50萬(wàn)年前):智人(Homo sapiens)在非洲出現(xiàn)并遷移到歐洲。
4)晚期智人(新人)階段(25萬(wàn)年-3萬(wàn)5千年前):現(xiàn)代人(Homo sapiens sapiens)在非洲南部出現(xiàn),約5萬(wàn)年前,現(xiàn)代人類分布到中東地區(qū),到3萬(wàn)5千年前,現(xiàn)代人類分布到達(dá)歐洲-克羅麥昂人(Cro-Magnon);
5)在更新世晚期,大約3萬(wàn)-2萬(wàn)年前,現(xiàn)代人類通過(guò)白令陸橋進(jìn)入北美洲并向南遷移。進(jìn)入全新世后,現(xiàn)代人的分布到除南極洲以外的各個(gè)大陸,并且成為唯一生存至今的人科動(dòng)物(hominids)。
6)2004年出版的國(guó)際地層表已取消了第四紀(jì)作為“紀(jì)”一級(jí)地質(zhì)年代的地位,但是在國(guó)際第四紀(jì)學(xué)界引起了軒然大波,后又予以恢復(fù)。
