Nothosaurus Facts

The Nothosaurus was a dinosaur that lived in the water during the Triassic Period. Nothosaurus means “false lizard.” It was approximately 10 feet in length and on averaged weighted between 150 and 200 pounds. The Nothosaurus had a long tapered body and at the send was a narrow head that contained sharp teeth.  The fossils were found all over the world.  The Nothosaurus also are known to be the earliest sea-living reptilian hunters of the waters. There have been many full fossil structures found; one rare species can be seen in the National History Museum in Berlin.

The Nothosaurs was able to defend itself with its sharp teeth and the ability to swim away from land predators. As this dinosaur evolved, it became even larger and more dangerous.

The fossil records of the Nothosaurus are vital to scientists. They were able to study this marine reptile and learn that there were over a dozen species of this dinosaur. The fossils have been discovered all over the world. They were found in Europe, Africa, and Asia.

What did they eat?

It is said that the Nothosaurus lived in shallow warm rivers and seas, so scientist believes they would eat fish, crabs, other crustaceans, and possibly eggs.


This dinosaur was one of the first that was able to live in the sea and still come out on land.
