How Livyatan And Megalodon Clashed In Ancient Prehistoric Ocean Battles

Nine million years ago, off the coast of what is now Peru, the biggest shark that ever lived and the whale with the biggest biting teeth of any animal hunted the same sea. In this video, you are a small whale caught between them. We look at how Megalodon and Livyatan were built, how each one would have hunted you, what the fossils actually say about fights between them, who would win in a one-on-one battle (speculation, clearly labelled), and why both giants disappeared.

WHAT WE KNOW Megalodon lived about 23 to 3.6 million years ago; big adults reached around 15 m, the largest perhaps much more Livyatan lived about 9 to 10 million years ago in Peru; about 13 to 17 m long, with teeth up to 36 cm, the largest biting teeth of any known animal Fossils of both come from the same rocks in the Pisco Formation, Peru No fossil records a battle between them; known bite marks include a shark bite on a sperm whale tooth root (North Carolina) and scavenging marks on a Livyatan skull (Peru) Both disappeared as the oceans cooled; the great white is not a descendant of megalodon SOURCES AND FURTHER READING Lambert, O. et al.
