Gran Dolina site at Atapuerca reveals almost exclusive use of local chert 400,000 years ago

A paper published in the journal Quaternary International reveals a distinctive technological behavior at level TD10.2-BB of Gran Dolina (Atapuerca, Burgos), characterized by the almost exclusive use of local chert and linked to one of the earliest pieces of evidence of communal hunting in the human evolutionary record, dated to around 400,000 years ago.
