Abstract: There are four mammalian faunas of the Early Pleistocene in the Chongzuo, Guangxi: the Baikong fauna (2.00 Ma); the Juyuan fauna (1.80 Ma); the Sanhe fauna (1.20 Ma); the Queque fauna (1.00 Ma). Event 6 (2.60 Ma) was earlier than the Baikong fauna, and named the Gigantopithecus blacki LSD. Event 7 (1.90 Ma) was between the Baikong and the Juyuan fauna, corresponds to the Ailuropoda wulingshanensis LSD. Event 8 (1.00 Ma) was latter than the Queque fauna, called the Sinomastodon HSD. The bio-events apparently occurred near the ends of the cold period or at the beginning of the warm period.
