【Abstract】 Gigantopithecus is a fossil ape only from south China and covered from Early Pleistocen to early Middle Pleistocene in age. Its fossils were collected from the cave sediments of southern China, such as Guangxi and Hubei. The last work shows that the sediments with the Gigantopithecus fossils were only scattered in the regions south to the Yangtze River. This paper mainly focuses on the early Early Pleistocene strata with Gigantopithecus in the Longgu Cave from Gaoping at Jianshi County, west Hubei. The strata consist of the cave sediments, and are named Gaoping Formation in this paper. The Gaoping Formation is widely distributed in west Hubei, is about 5m in thickness and is mainly composed of the clay and sandy clay at the Longgu Cave. According to the mammalian fauna and magnetic stratigraphy, the Gao- ping Formation is correlated with the sediments of the Gigantopithecus Cave at Liucheng, Guangxi, Locality 18 at Zhoukoudian, Beijing and the lower part of the Yuanmou Formation in the Yuanmou Basin, Yunnan. The Gigantopithecus from the Longgu Cave is earlier than 1.93 Ma in age.更多还原
