The Jaiojie Paleolithic Site is located in a karstic cave at Acheng, w:st="on">Harbin w:st="on">City in w:st="on">w:st="on">Heilongjiang w:st="on">Province. The geographic coordination at the cave entrance measured with the Global Positioning System (GPS) is 45°w:st="on" TCSC="0" NumberType="1" Negative="False" HasSpace="False" SourceValue="21" UnitName="’">21’07.7″N and 127°w:st="on" TCSC="0" NumberType="1" Negative="False" HasSpace="False" SourceValue="5" UnitName="’">05’16.8″E, with an altitude of w:st="on" TCSC="0" NumberType="1" Negative="False" HasSpace="False" SourceValue="183" UnitName="m">183 m. The cave deposits can be divided into 6 layers. Mammalian fossils were unearthed mainly from Layers 5 and w:st="on" TCSC="0" NumberType="1" Negative="False" HasSpace="True" SourceValue="6" UnitName="in">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 w:st="on">Liaoning w:st="on">Province, the Late Pleistocene Xiaogushan and Gulongshan faunas, also in w:st="on">w:st="on">Liaoning w:st="on">Province. The fauna is therefore biochronologically dated as the late stage of the Middle Pleistocene.
