這隻不是恐龍，但牠是史前時代最有名的動物之一，所以在 Dino Wiki 也有一席之地。

酷東西

趣味知識

Livyatan had teeth up to 36 centimeters (over 14 inches) long, bigger than any other sperm whale.1

Its skull was about 3 meters (10 feet) long, making it the largest fossil sperm whale skull known.1

Livyatan lived at the same time as the giant shark Carcharocles megalodon, and both were top predators.1

Scientists think Livyatan could bite harder than any other four-legged animal ever found.1

Unlike modern sperm whales that suck in food, Livyatan used its teeth to hunt and tear large prey.1

The name Livyatan comes from a Hebrew word for a sea monster, and the species name melvillei honors the author of Moby-Dick.1
