Of all the predators ever to prowl our planet's oceans, few can hold a candle to Otodus megalodon and Livyatan melvillei in terms of pure size and power. And not only did these titans exist; they existed at the same time! How their inevitable interactions would have played out is a topic many have discussed, and it's not uncommon to see people suggesting that Livyatan outright preyed on O. megalodon. But could this be a step too far? What evidence is there to support this, if any? Let's find out!
