You've never seen a dinosaur book like this before! The Ultimate Dinosaur Encyclopedia is a whole new type of encyclopedia, developed in conjunction with cutting-edge 3D-art and science. Using groundbreaking recent research, palaeontologist Chris Barker recreates the world of prehistoric giants with photorealistic images more lifelike than any you've seen before.

Use the free AR app to view the pages, and you'll see dinosaurs spring into life with stunning 3D. As well as learning about their appearance and behaviours, the app lets you see them as breathtaking life-size models. Selected pages even have video clips that seem to play right on the page. Short of hopping in a time machine, it's the best way to get close to these amazing animals.

The book explores every era of prehistoric life, beginning with the origins of life in the world's oceans, moving to the first land-based vertebrates, and on to the reign of the dinosaurs and beyond. Based on only the most modern and authentic science, some familiar dinosaurs take on a whole new appearance. See these majestic creatures in their natural habitat, understand their parallels with modern animals, and learn everything about how they moved, ate, fought and hunted.
