Round Four: The Dominion Of Sea Predators

As we explore the underwater realm, we encounter Shastasaurus, the largest marine predator known to have lived 235 million years ago. Its colossal size and weight make it an intimidating force, but it falls short in comparison to the modern sperm whale, which outweighs it and rivals its length. The modern sea creature claims victory in this round.
