A rare, well-preserved ancient human skull found in central China could be a million-year-old Homo erectus. As excavation of the fossil continues, archaeologists and palaeoanthropologists anticipate that the skull could give a fuller and a detailed picture of the diverse family tree of archaic humans living throughout Eurasia in prehistoric times. It lies 35 metres from where two significant finds — dubbed the Yunxian Man skulls — were unearthed in 1989 and 1990.
