It is hard to imagine that the now arid and desolate land of Nevada was once an ocean 250 million years ago, and that the ichthyosaurs appeared in the seas long before the dinosaurs emerged. They were the first reptiles on Earth to leave the land and evolve into marine creatures. Over thousands of years of evolution, the ichthyosaurs underwent significant changes in their shape, completely losing their ability to live on land, yet dominated the oceans for tens of millions of years with their massive size. Today, a fossilized skeleton of an ichthyosaur has led scientists to an astonishing discovery. The "sharp-toothed ichthyosaur," at the top of the food chain, has completely changed scientists' understanding of this early marine reptile. Research on it will fill in the missing link in the evolution of ichthyosaurs.
