The just of it:
In African, bones of human lineage have been found, that have tooth marks from Crocodylus anthropophagus, meaning "man-eating crocodile."
It may have been the largest predator encountered by in Africa and it lived some 1.84 million years ago. It had a deep snout and prominent triangular horns.
"It was probably as large as a modern Nile crocodile, one of the largest living crocodilians at between 18 to 20 feet," Brochu said. "One thing to bear in mind was that while these crocodiles are not necessarily bigger than the ones today, hominids back then were smaller than we are today, so the crocodiles would have been relatively quite a bit larger."
