A new species of ancient human has been unearthed in the Afar region of Ethiopia, scientists report.
Researchers discovered jaw bones and teeth, which date to between 3.3m and 3.5m years old.The teeth showed signs of violent clenching and grinding suggesting the individual was an aggressive and confrontational character.
It means this new hominin was alive at the same time as several other early human species, suggesting our family tree is more complicated than was thought.
The new species has been called Australopithecus deyiremeda, which means "close relative".
The ancient remains are thought to belong to an individual, who would have had both ape and human-like features as shown in the recreation pictured above
