A brief introduction to the Zhoukoudian Caves

Zhoukoudian is a small village situated about 50 km southwest of Beijing In 1928, Dr C. C. Young, a famous Chinese paleontologist, and Wenzhong Pei, a young Chinese geologist joined the excavation. Two lower jaws of Peking Man were unearthed in this year. To make the excavation more successful, Dr Weng and Dr Black established "Cenozoic Research Laboratory" in 1929. The Peking Man Site also provides the more precise scientific data for the study of the evolution, behaviour. On the western side of Zhoukoudian Village, there are two parallel hills. The one on the east is lower and called Dragon-bone Hill. Zhoukoudian is a relic of primitive culture, 48 kilometers southwest of downtown Beijing, where Longgushan(dragon skeleton mountain) is standing. Several decades ago, local farmers mined limestone in Zhoukoudian, came upon some bone fossils and called them "the Dragon Bones". Zhoukoudian became known as "Dragon Bone Mountain". Drugstores purchased the bones as a medical ingredient. The news about the "magic bones" drew attention of scientists. In 1929 these limestone caves became world famous with the discovery of a skull and two teeth dating back 200,000 to 500,000 years. They were named Peking man.

The historical and cultural value of the Zhoukoudian site has been acknowledged by its listing as a World Heritage Site in December 1987 at the eleventh session of UNESCO.
