Come with me to travel with Professor Ampere Volt's Time Machine! We will reach distant eras, meet great figures, encounter wild beasts, explore interesting places, and solve the strangest mysteries of History. We will have a great time! I guarantee it, I, Geronimo Stilton. Have you ever been chased by a Tyrannosaurus Rex? Eaten an omelet made from prehistoric eggs? Had a Quetzalcoatlus, the largest flying creature of all time, fly over your head? Well, it has happened to me! I started a journey through time with the Rodentonautilus, Professor Volt's amazing machine, and suddenly found myself in Prehistory trying to discover why the dinosaurs disappeared... By the thousand de-feathered pterosaurs, I experienced one of the most exciting adventures of my life!
