Beijingers, also known as Beijingers, whose scientific name is Homo erectus pekinensis, also known as Sinanthropus pekinensis, are homo erectus living in Pleistocene. Its fossil remains were found in Longgushan 1927, Zhoukoudian, southwest of Beijing, China. There is a great controversy about its age, which is generally considered to be about 500 thousand years. The application of an Al/Be dating method recently published in the British journal Nature pushed this age to 680,000-780,000 years ago. Beijingers in the modern sense generally refer to people who live or live in Beijing.
