Extreme Dinosaurs takes the hugely popular subject of dinosaurs and presents it in an entirely new and dynamic format. Using colourful, newly commissioned illustrations, only the very extreme dinosaurs feature here, from the huge and lumbering Brontosaurs to the terrifyingly ferocious Spinosaur and the tiny Microraptor. Imaginative text offers a vivid description and detailed information about these extraordinary creatures; including unusual facts (what do you call a fossilized dinosaur poo?) and fascinating statistics.This approach covers all the information that any self-respecting dinosaur fanatic would expect to see ? What were they? How do we know so much about them? Where do they fit into the evolution of modern-day animals? How did they live, feed, move and breed? Why did they become extinct? What really sets this book apart, however, are the special items. Intended to create a truly interactive experience, these range from a dinosaur mask and a dinosaur speed calculator for calculating the speeds of the fastest dinosaurs on earth to -peelable- dinosaur eggs, showingthe development of a dinosaur embryo, and a mocked-up CT scan of a very stupid dinosaur, showing it?s tiny brain.
