A newfound horned crocodile may have been the largest predator encountered by our ancestors in Africa, researchers now suggest.

Scientists have even found bones from members of the human lineage bearing tooth marks from this reptile, whose scientific name, Crocodylus anthropophagus, means "man-eating crocodile."

This predator, which lived some 1.84 million years ago, possessed a deep snout that would have made it look more robust than modern crocodiles. It also had prominent triangular horns.
