禄丰古猿在中国云南元谋的发现，为了解东亚早期人科动物的演化提供了重要线索。然而，动物群的年龄和古生态学仍有待确定。雷老是中国元谋人科化石产地之一，最近在雷老采集到一个小型哺乳动物化石组合，包括4目16科41种，是中国西南地区新近纪小型哺乳动物群中最具多样性的化石。本文分析了小型哺乳动物区系的分类、时代和古生态。元谋古猿动物群现在被认为比禄丰动物群更古老，目前被认为对应于大约9 Ma的年龄。微型哺乳动物区系表明，主要是森林的栖息地，与边缘环境组成的草地。
The discovery of Lufengpithecus at Yuanmou, in Yunnan Province, China, provides important clues to understanding the evolution of early hominoids in eastern Asia. However, the age and paleoecology of the fauna remain to be established. An assemblage of micromammalian fossils, collected recently by screenwashing at Leilao, one of the hominoid-bearing localities at Yuanmou, contains 41 species belonging to 16 families and 4 orders, and represents the most diverse Neogene micromammalian fauna known from southwestern China. This paper presents an analysis of the taxonomy, age, and paleoecology of the micromammalian fauna. The Yuanmou hominoid fauna is now considered older than the Lufeng fauna, and is currently thought to correspond to an age of about 9 Ma. The micromammalian fauna indicates a predominantly forested habitat, with marginal environments consisting of bush-grassland.
