Encyclopaedia

326 dinosaurs

When they lived, where they have been found, how big they grew, what they ate, and who named them. Every figure is from the Natural History Museum's records, and every one is drawn to scale beside a person.

Every dinosaur in the encyclopaedia as a thin line across the time it lived, from 235 to 66 million years ago, oldest at the top. The lines crowd into the Late Cretaceous, where nearly half of them come from, and all stop at 66 million years ago.TriassicJurassicCretaceousEoraptor: 228–228 million years agoHerrerasaurus: 228–228
