Extinct Dinosaur Animals

Monday, February 21, 2011


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.

Dunkleosteus "terrible fish"

Dunkleosteus, a voracious carnivorous fish, lived about 400 million years ago. It measured up to 11.5 ft long and had huge jaws with scissor-like cutting serrated, razor-sharp bones instead of teeth. Its skull was was over 2 feet long. They were not sharks. They ate sharks!


Dinichthys lived about 400 million years ago. It was about 30 feet long and weighed over 2 tons. It probably was not agile and waited in the plants of the sea floor to ambush its prey.
