Strangest Prehistoric Creatures To Rule The Earth
Purussaurus was a gigantic caiman (a relative to alligators) that lived in what is today known as the Amazonian rainforest. Back in Purussaurus days, 8 million years ago, that region was actually a vast inland sea teaming with crocodiles, gharials, fresh water whales, giant rodents and enormous turtles. Purussaurus was the top predator in that sea, and with good reason; at 1215 meters long, maybe more, it was one of the largest crocodilians ever to have existed. The remains of other animals missing limbs or bitten in half are a macabre proof of this giant caimans appetite.
