The sea monsters terrorized the oceans from about 16 million to 2 million years ago. Scientists understand this came as a result of a period of global cooling, when the temperature of our oceans dropped by several degrees. While there would have been early human ancestors around at the time, modern humans did not evolve until much later. Leviathan Weighed as Much as 50 Tons.
