Abstract: The present paper introduces briefly the progress of ongoing research at the Miaohoushan site in Liaoning Province, which is the earliest human occupation in northeast China at the present time. The study shows that stone artifacts including choppers, cleavers, spheroids, picks, scrapers, notches, and bipolar artifacts are similar in technology and typology to the industry at the Zhoukoudian Homo erectus site. The “Miaohoushan fauna” consists of the essential elements of the Zhoukoudian fauna dating to the Middle Pleistocene. New uranium-series dating indicates the age of the Miaohoushan to be at least 500 ka BP.

Key words: Miaohoushan site; Stone artifacts; Mammalian fossils; Middle Pleistocene
