Platypterygius australis, an ichthyosaur (marine reptile), lived 105 to 100 million years ago and swam the Eromanga Sea, a large inland seaway that covered much of Eastern Australia during the Cretaceous period. Platypterygius australis weighed 3,500kg and possessed an elongated jaw with over 200 teeth that it swept through the water to catch its prey of fish and squid.

Discovery: In 1990, Mary Waded studied a wide range of ichthyosaur material from Australia and concluded that the fossils represented a new species.
