The research team at the Atapuerca archaeological sites in Burgos, Spain, has just broken its own record by discovering, for the third time, the oldest human in Western Europe.

The prehistoric facial bones were found buried in 50 feet of mud and silt, and are believed to be 1.1 to 1.4 million years old, researchers said.

Researchers in Spain have discovered pieces of a fossilized face belonging to an ancient human ancestor. The fragments cannot be conclusively identified as any particular species.
