FROM THE EDITOR

There’s never been a better time to be a dino hunter. As new dig sites open up around the world, scientists are virtually tripping over near-pristine fossils, identifying totally new species every week. And with each discovery, the past vision of scaly beasts lumbering across vast plains has started to come into sharper focus, revealing a vibrant world populated by the kind of rich biodiversity we see in the wildest places on Earth today.

In particular, we’re really starting to understand what these creatures looked like. It’s a crucial part of the picture, since we know that an animal’s appearance is usually a response to the world around it: some species find success in camouflage, while others find flamboyance more useful. So as we start to resolve the finer details of the colours and patterns of dinosaurs, we also start to see the world in which they lived. And as it turns out, that world may have been an even more ferocious place than we once thought. Head to p48 to find out how scientists are looking back in time at our prehistoric planet.
