禄丰古猿化石地小哺乳动物研究进展简述

A brief introduction to the research progress of small mammals in the Lufeng hominoid locality

云南禄丰古猿化石地是中国西南地区最重要的晚新生代化石地之一,已发现化石类群超百种,其中小哺乳动物类群超过三分之一.通过对化石地的地理地貌、地层情况、化石地动物类群进行总结,并对小哺乳动物的类群鉴定研究、生物地层年代学和古环境重建中的应用研究进行综述.可见,禄丰古猿化石地的小哺乳动物化石类群归属进行了较多的地层年代研究,但是生物年代学与古地磁研究存在明显差异;小哺乳动物在古环境重建研究中优势尚未得到充分的利用.

The Lufeng hominoid locality in Yunnan is one of the most important late Cenozoic fossil sites in Southwest China.More than 100 fossil groups have been found,including more than one third of small mammal groups.However,there is still a lack of summary work of small mammals at present.In order to improve the understanding of the research progress of small mammals in this locality,this paper briefly summarizes the animal taxa in this locality,and research status of small mammals including group identification and application of small mammals in biostratigraphic chronology and paleoenvironment reconstruction.Conclusion:the group classification has been comprehensively and systematically studied;At the same time,many stratigraphic dating studies have been carried out by using small mammal assemblages,but there are obvious differences between biological chronology and Paleomagnetism;In addition,the advantages of small mammals in Paleoenvironment reconstruction have not been fully utilized in the this locality.
