Abstract: Numerous mammalian fossils from Western Taiwan Strait were briefly discribed here. Concerning the age, besides an antler of Cervidea dated to late Tertiary, other specimens were suggested to be of late Pleistocene, such as Ursus sp., Elephas maximus, Dicerorhinus sp., Sus sp., Cervus unicolor, Cervus nippon and Bubalus bubalus, and early Holocene, including Cetacea gen. et sp. indet., Elephas sp. Sus scrofa, Cervus unicolor and Cervus nippon etc. The Late Pleistocene and Early Holocene faunal assemblages of Western Taiwan Strait differ from contemporary faunal assemblages ei ther from other sea area in China or localities at middle-western mountain area in Fuji an, they probably represent a local branch of Ailuropoda—Stegodon fauna occurred along the Southeastern coast of China.
