| 摘 要： | 对三汇坝牛尾洞发现的19种哺乳动物化石应用数理统计分析、铀系和含氟量测年分析、孢粉分析进行了研究.论证了它们是一个晚更新世时生活于亚热带暖热湿润气候中的乔木林-灌木林-湿草地动物群.通过它与四川盆地第四纪的几个典型动物群相比较,证明其性质仍是我国南方广义“大熊猫-剑齿象动物群”之一员.其特点鲜明,是该动物群演化发展过程中的一环,介于歌乐山与资阳两动物群之间.

| Abstract: | This paper deals with 19 species of mammal fossils unearthed at Niuweidong (Cattle Tail Cave), Sanhuiba, Hechuan, Chongqing, Sichuan, China. Mathematical statistic analysis, Uranium (U) series analysis, Fluorine (F) content analysis and Pollen analysis were used in this study. It is proved that it was one of Forest-Shrubbcry-Grassland Faunas which lived in warm and moist environment in the Late Pleistocene. Having been compared with the several standard faunas in the Quaternary found, in Sichuan Basin, it is shown-that, in general, it is one of the Ailuropoda-Stegodon Faunas in the Southern China. However, it has its own characteristics. Hence, it is suggested that it is one of the links in the evolutionary process in which the Ailuropoda-Stegodon Fauna evolutioned, and is positioned between Geleshan (i. e. Roloshan) Fauna and Ziyang(i. e. Tzeyang) Fauna. |
