Extinct Animals 8
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.
The Tylosaurus was a large marine lizard, 20 to 45 feet long, which lived during
the Cretaceous about 88 to 78 million years ago. It had lots of teeth and
ate other marine creatures. Fossils have been found in North America
and New Zealand.
Ichthyosaurs were reptiles (not fish) that lived during the
Triassic (208 to 248 million years ago) and became extinct during the
Cretaceous (65 to 146 million years ago) about 95 million years ago.
They measured up to 40 feet long, had strong jaws, sharp teeth and big eyes
to see their prey.
