对贵州省境内的双河洞历次科考中发现的第四纪动物群化石进行初步研究和总结,认为目前对双河洞第四纪动物群研究尚处于起步阶段,化石的发现者都是洞穴科考专家,古生物知识相对欠缺且重视不够是洞穴化石研究进展缓慢的原因。为了加快双河洞第四纪动物群的研究进程,以今年中法联合科考过程中发现的大熊猫-剑齿象动物群化石为样本,采用ICP-MS铀系定年方法对这批大熊猫骨骼化石碳酸盐岩包裹物的年龄进行测试,结果表明该化石群化石距今6.75万年,初步判定此动物群可能生存于中更新世-晚更新世早期。这批哺乳动物化石及其地层信息将为贵州(尤其是黔北)第四纪的研究提供重要资料。
Based on the preliminary study and conclusion of Quaternary fossils found in previous studies of Shuanghe Cave in Guizhou Province, it is believed that the research on quaternary fauna in Shuanghe Cave is still in its infancy, and the fossils are found in caves Expedition experts, the relative lack of paleontological knowledge and insufficient attention is the reason for the slow progress of cave fossils. In order to speed up the research process of Quaternary fauna in Shuanghe Cave, taking the giant panda-Stegosaur fauna found during the Sino-French joint expedition this year as samples, the ICP-MS dating method of uranium series The age of fossil carbonate packs was tested and the results show that the fossil fossils have been dated for 675,000 years ago, and the fauna may have preliminarily been found to survive in the middle Pleistocene-early Pleistocene. These mammalian fossils and their stratigraphic information will provide important information for the Quaternary research in Guizhou (especially in northern Guizhou).
