摘要	The Yanjinggou fauna has long been recognized as the quintessential Middle Pleistocene fauna in South China. However, the recent discovery of the Dayakou fauna in the same region has unveiled a fossil assemblage indicative of the Early Pleistocene. Our new excavations at the Dayakou pit have yielded a substantial increase in fossil materials, which not only enriched the composition of the local fauna but also play a pivotal role in reconsidering the geochronology of the faunal complex in Yanjinggou area. The newly recovered fossil remains from the Dayakou pit comprise at least ten mammal taxa, including carnivorans ( Homotherium sp., Neofelis nebulosa, Panthera tigris and Ailuropoda melanoleuca wulingshanensis), proboscidean ( Stegodon huananensis), perissodactyls ( Hesperotherium sinense, Tapirus sinensis and Rhinoceros cf. sinensis), and artiodactyls (Cervini gen. et sp. indet. and Leptobos sp.). thereinto, A. m. wulingshanensis, T. sinensis and Leptobos sp. represent the first discoveries of their kinds in the Yanjinggou area. The faunal combination, along with the combined ESR and Useries dating of the Stegodon tooth, resulting in an age estimate of 1010 +/- 115 ka, suggests that the geologic age of the mammalian assemblage of the Dayakou pit corresponds to transition phase from the middle to late Early Pleistocene. Our study challenges preconceived notions and provides a more sophisticated understanding of the temporal framework for the Yanjinggou faunal complex, offering new insights into the Pleistocene mammalian faunas of South China. Furthermore, the Dayakou fauna is proposed to mark the onset of Early-Middle Pleistocene Transition mammalian faunas in South China, reflecting an ecosystem of mountainous subtropical forest mixed with arbor and shrub vegetation. The Dayakou locality witnesses the first appearances of modern clouded leopards and tigers in Asia, prompting the origin and early dispersal considerations of these two species.
