Ichthyosaurs and other marine reptiles are sometimes mistakenly called dinosaurs. This rare example shows the skin as a thin organic layer preserving the ouline of the body in a specimen at the Hunterian Museum.

Lots of information about the various groups of marine reptiles.

Having trouble pronouncing those long names? Want to know what they mean or who named them? Ben Creisler has compiled an excellent listing of the names and their origins.

During the late Cretaceous, half of Arkansas was submerged under a shallow ocean called the Western Interior Seaway. Mosasaurs and other strange creatures lived in this ocean. When they died, sometimes their bones were preserved as fossils.

Information about prehistoric marine reptiles of New Zealand, where, whom, when and what was found. Paleogeographic information, where in New Zealand to see fossil material displayed, suggested reading material and links to other related websites.

Late Cretaceous marine fossils from the Western Interior Seaway. More than 50 pages of information on mosasaurs, plesiosaurs and other fossils found in Kansas and the Midwest.

Introduction to the group including taxonomy, reconstructions, and original artwork.

From the Museum of UnNatural History

While dinosaurs ruled the land, the ichthyosaurs shared the seas of the world with the other great groups of large marine reptiles, the plesiosaurs and mosasaurs.

This site is intended to give serious and detailed information on the Order Plesiosauria, to provide a forum for discussion and for the presentation of ideas no matter how wild and fanciful on the palaeontology, taxonomy, biomechanics, biology and ecological role of members of the order.
