关于广西崇左地区早更新世的三次生物事件

在广西崇左地区已发现4个早更新世的哺乳动物群,从老到新分别是:鲤鱼山百孔洞动物群(距今约200万年);泊岳山的巨猿洞动物群(距今约180万年);三合大洞动物群(距今约120万年);以及缺缺洞动物群(早于距今100万年)。事件6距今约260万年,应出现在百孔洞动物群之前,为步氏巨猿的最低层位事件(The Gigantopithecus blacki LSD)。事件7距今约190万年,应当出现在泊岳山的巨猿洞动物群和百孔洞动物群之间,为武陵山大熊猫的最低层位事件(The Ailuropoda wulingshanensis LSD)。事件8距今约100万年,应出现在缺缺洞动物群的末尾,为中华乳齿象的最高层位事件(The Sinomastodon HSD)。生物事件有规律地出现在寒冷期的末尾,或温暖期的开始。

Three Bio-Events of the Early Pleistocene in Chongzuo,Guangxi

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.
