In size comparison with Otodus megalodon, how did Livyatan compare ecologically?

Answer

It occupied a similar ecological space, possibly leading to competition over medium-sized whales.

Livyatan melvillei coexisted with the contemporary apex predator, the Otodus megalodon shark, during the Miocene. In terms of sheer estimated size, Livyatan was a peer to the massive shark. Although the Megalodon likely possessed a more powerful bite force optimized for crushing bone, Livyatan’s weaponry—its massive, interlocking teeth capable of shearing—allowed it to engage in similar high-stakes predation. This overlap in size and capability strongly suggests that the two mega-predators occupied a similar ecological niche, which would have inevitably led to direct competition for shared food resources, such as medium-sized whales.
