Icthyosaurs lived in the ocean from 245 to 90 million years ago. Too many dinosaurs existed during that period to name them all. The first dinosaurs, such as Eoraptor, evolved around 225 million years ago. During the Jurassic, around 145 million years ago, there were dinosaurs such as Apatosaurus, Diplodocus, Camarasaurus, Stegosaurus, Allosaurus, Torvosaurus, and Ceratosaurus.
