Size comparison: Livyatan vs Megalodon

Size comparison between the Livyatan and the Megalodon.

These two marine animals lived during the same period. The Livyatan did not prosper as long as the Megalodon. Their respective dimensions remain uncertain. Since most of the time we only find teeth; those of the Megalodon are recovered in large quantities in the Pacific, it is often enough to scrape the seabed with a trawler.
