Mosasaur Fossils

Mosasaur fossils on display at the Muséum national d'histoire naturelle in Paris, France. Learn more at the mosasaur entry at Wikipedia.

UPDATE: Mosasaur fossils on display at the Smithsonian National Museum of Natural History in 2010. The skull fossil is a Clidastes liodontus and the full fossil is Tylosaurus proriger both from Kansas of the Late Cretaceous (80-70 mya).

Cryptoclidus oxoniensis

Pictures taken at the Muséum national d'Histoire naturelle in Paris, France.  Doing some research on the new movie that is now showing at the Louisville Science Center IMAX called Sea Rex: Journey to a Prehistoric World, I found these marine reptile images I took last year.  The natural history museum building is shown in the film in a re-creation of a historical paleontological event.  I need to see this film again and might have some future comments about some of the historical scenes shown in this movie.

The fossil of the marine reptile shown in these pictures are of the Cryptoclidus oxoniensis found in England.  It is a type of plesiosaur from the Middle Jurassic Period.  See this link on Wikipedia for more information.
