摘要
Zhoukoudian (ZKD), a tiny village, is about 50 kilometers southwest of downtown Beijing. Since ancient times, it has been noted for its abundant trove of mammal fossils, as the hilly area in the vicinity is at the end of a dismembered branch of the Taihang Mountains, where they meet the North China Plain. There are a lot of well-developed and well-preserved Pleistocene sediments with valuable fossilized records in this area. Its great value for the study of human ancestry was first discovered by Western scholars in 1921.
