Putaoyuan Paleolithic site from the Lower Pleistocene of the Nihewan Basin

Seventy-nine stone artifacts were discovered from a Lower Pleistocene context at the Putaoyuan site, Nihewan Basin (or Sangganhe Basin). The stone artifacts include cores, flakes, modified pieces and chunks. Bone and tooth fragments of mammalian fossils, including elephants, equids, and rhinocerids were also collected. Judging from the magnetostratigraphic context, the cultural horizon is close to the Olduvai subchron, which indicates early human occupation probably took place about 1.5-1.6 million years ago.
