Zhoukoudian Locality 1 also known as the Peking Man Site is a cave site in Beijing famous for the discovery of the first fossils of Peking Man or Homo erectus pekinensis [1]. With a find of 6 fairly complete hominin crania and bones representing at least 40 individuals, 98 species of non-hominin mammalian fossils, and tens of thousands of stone artefacts, Zhoukoudian Locality 1 has remained the largest single source of Homo erectus (pekinensis) and is one of the most important palaeolithic sites in the world [2][3][4][5][6].
