Zeuglodon

Zeuglodon

The Zeuglodon, or Basilosaurus, "King of the Reptiles", lived during the Eocene about 40 to 50 million years ago. It was an early, 44 toothed, 55 to 75 foot long whale species with small hind legs.  Zeuglodon remains have been found in North America and Africa and it's Alabama's State Fossil.

The Zeuglodon has been extinct for about 37 million years.  Although you might want to keep your eyes open when swimming.  Some believe the large serpent sightings of Loch Ness Monster in Scotland, Lake Okanagan in Canada and other lakes around the world may be descendants of the Zeuglocon or a related species.
