"Imagine, if you will, a world filled with billions of dinosaurs. A world where they can be found in thousands of shapes, sizes, colours and classes in every habitable pocket of the planet. Imagine them from the desert dunes of the Sahara to the frozen rim of the Antarctic Circle - and from the balmy islands of the South Pacific to the high flanks of the Himalayas. The thing is, you don't have to imagine very hard. In fact, wherever you live, you can probably step outside and look up into the trees and skies to find them. For the dinosaurs are the birds and they are all around you. Dinosaurs didn't die out when an asteroid hit the earth 66 million years ago. Everything you were told as a child was wrong."
