Fragments of the left side of the skull of a human relative have been discovered in Spain, revealing the face of the oldest human ancestor ever discovered in Western Europe.

The fragmentary facial bones belong to Homo affinis erectus, an esoteric offshoot of our family tree that inhabited Spain more than one million years ago.

A fossil of a partial face from a human ancestor is the oldest in western Europe, archaeologists reported Wednesday. The incomplete skull — a section of the left cheek bone and upper jaw – was found in northern Spain in 2022. The fossil is between 1.1 million and 1.4 million years old, according to research published in the journal Nature.
