Peking Man also called Sinanthropus pekinensis, is an example of Homo erectus. Zhoukoudian is a small village situated about 50 km southwest of Beijing.
In 1918, the famous Swedish geologist and archaeologist Johann Gunnar Andersson was told that there were some fossils at the 'Chicken-bone Hill' in Zhoukoudian. He was then serving as an adviser on mineral affairs in the Ministry of Agriculture and Commerce of the Chinese Government, and collected a lot of rodent fossils.
In 1921, when Austrian palaeontologists Andersson and Otto Zdansky, surveyed at Zhoukoudian again, local people informed them that there were more fossils on another hill which is named 'Dragon Bone Hill'. They started an excavation, the most important discovery were two human-like teeth this time. This discovery astonished the scientific world as no this kind of ancient human fossil had been found in Asia before that.
In 1928, two lower jaws of Peking Man were unearthed.
In 1929, the first and almost complete skull cap of Peking Man was found in the red sandy clay in a branching cave.
More and more fossils and Peking Man's tools, even some easy adornments were unearthed in the next years, anthropologists and archaeologists analysed and summed that
Peking Man made tools with vein quartz, quartz crystals, flint, and sandstones. Another mark of Peking Man's cultural progress is the use of fire.
The exposure of sedimentary strata around Zhoukoudian is quite extraordinary, this site illustrated the process of hominization, in 1987, the Peking Man Site at Zhoukoudian was formally inscribed on the "World Heritage List".
