The teeth of "Leviathan Melvillei" were so large it was initially assumed they were elephant tusks.
"There were no elephants in South America before 3 million years ago, and the specimens found have an age of 12 to 15 million years, so that was impossible," said Professor Jelle Reumer, one of the team of scientists who found the fossil in the Pisco-Ica desert in coastal Peru.
