This exciting volume follows the life of an ichthyosaurus, a marine reptile resembling a dolphin. The ichthyosaurus must navigate the dangerous waters of the Jurassic Period, evading much larger marine dinosaurs and hunting for food. Detailed illustrations and engaging text guide readers through the journey of this dinosaur. Dinosaur facts and photographs of fossils show young readers that the world of the ichthyosaurus was not a fantasy, but a reality 200 million years ago.
