AN lang=EN-US>The Jaiojie Paleolithic Site is located in a karstic cave at Acheng, hemas-microsoft-com:office:smarttags" />Harbin City in Heilongjiang Province. The geographic coordination at the cave entrance measured with the Global Positioning System (GPS) is 45°21’07.7″N and 127°05’16.8″E, ang=EN-US>with an altitude of 183 m. The cave deposits can be divided into 6 layers. Mammalian fossils were unearthed mainly from Layers 5 and 6 in the lower part of the cave deposits. The comparison of fauna compositions shows that the Jiaojie fauna is close to that of the Middle Pleistocene Jinniushan and Miaohoushan faunas in Liaoning Province, the Late Pleistocene Xiaogushan and Gulongshan faunas, also in Liaoning Province. The fauna is therefore biochronologically dated as the late stage of the Middle Pleistocene. hemas-microsoft-com:office:office" />
