Peking Man, Homo erectus pekinensis (formerly known by the junior synonym Sinanthropus pekinensis), is an example of Homo erectus. Discovered in 1923–27 during excavations at Zhoukoudian (Chou K'ou-tien) near Beijing (written "Peking" before the adoption of the Pinyin romanization system), China, in 2009 this group of fossil specimens dated from roughly 750,000 years ago, and a new 26Al/10Be dating suggests they are in the range of 680,000–780,000 years old.
