    Long in the tooth, but still a precious gem

    Known as the T.rex of the ocean, the only identified opalised tooth of the enormous marine reptile Kronosaurus (pliosaur), will go on display at the South Australian Museum today. 

    The Kronosaurus swam beneath the waves during the Early Cretaceous period when South Australia was covered by the Eromanga Sea and dinosaurs roamed the land. The sediments laid down on this ancient seabed now form the rocks of the Great Artesian Basin.
