Greek Skull Rewritten: A 300,000-Year-Old Relic Belongs to Homo Heidelbergensis

A 300,000-year-old skull found cemented in a Greek cave (the Petralona cranium) has been dated to at least 286,000 years old via uranium-series dating of the surrounding calcite, placing it with Homo heidelbergensis rather than Homo sapiens or Neanderthals. This suggests a widespread Middle Pleistocene population in Europe that coexisted with Neanderthals for over 100,000 years. No DNA can be recovered due to the long warm history of the fossil, and the find adds complexity to how scientists categorize early human relatives.
