摘要	Small mammals have short life spans, rapid reproductive cycles, wide distributions, and are sensitive to climate change. Composition of small mammal faunas is useful for reconstructing the paleoenvironment. Here we report the small mammals unearthed from the Dayin Cave, an archaeological site in Yunnan Province, Southwest China. Screen washing yielded two small mammal faunas. One has a radiocarbon date of approximately 32 ka BP. The other has a radiocarbon date around 18 ka BP, equivalent to the period of the Last Glacial Maximum (LGM). We performed taxonomic analyses, faunal comparisons, principal component analysis and cluster analyses on the small mammal fossils from the Dayin Cave. Our results show most of the species from the older fauna (similar to 32 ka) are forest-dwelling species, indicating the flourishing of forests and a relatively warm and humid climate. The younger fauna is dominated by Eothenomys, today an alpine-subalpine shrubland dweller, suggesting the flourishing of shrublands and perhaps a decrease in temperature. The stone tools discovered from the fossiliferous Layers 1 and 2 in. the Dayin Cave belong to the same type, suggesting that they were probably used by one hunter-gatherer group that lived in the Dayin Cave, and the populations were not affected by the cooling of the climate.
