If you're into dinosaurs, Brian Switek's writings are way to go. He writes for National Geographic and tweets about his expeditions.

Even though this book is technically for children, it is very enjoyable. The pictures are exquisite, and Switek never talks down to the reader. I think some of the dinosaurs and predators needed a little more information (instead of the science bites given), but it was still enjoyable and informative. And I always enjoy a dinosaur book that gives us pronunciation guides.
