Could Mosasaurus Survive in the Modern Ocean?

What if our prehistoric Mosasaurus, was placed across the seven seas of the modern day? Well today we explore a scenario where this marine reptile of the prehistoric past attempts to survive within our real world. Will it be able to dominate this harsh ecosystem, or will it struggle against its new contemporaries? There is only one way to find out!
