Abstract: The ruminants associated with Gigantopithecus fossils unearthed from the Sanhe Cave are systematically described. The identified taxa are as follow: Muntiacus lacustris, Cervavitus? cf. C. fenqii, Cervus(R.) yunnanensis, Megalovis guangxiensis, Caprinae gen.et sp.indet.,Bos(Bibos) sp. These fauna are most similar to those from the Gigantopithecus cave in Liucheng and Mohui Cave in Tiandong, Guangxi Autonomous Region. And these fossils confirm an Early Pleistocene age and an environment of a tropical bushy and forested environment favorable for habitation of high primates such as Gigantopithecus.
