What's a dinosaur watcher to do? Where do you go to find creatures that have been dead for 65 million years, and how do you know them when you see them? If you're a bird watcher, you get a field guide to the birds. Now dinosaur watchers can get their own field guide, a just-bigger-than-pocket-size encyclopedia of dinosaur science. The text is clear, objective, up-to-date, and dense with information, containing sections on every aspect of dinosaur discovery and biology. The heart of Dinosaurs is the guide. Each page in this section has an artist's portrait of an interesting dinosaur, tells how its name is pronounced and what it means, tells where and when it lived, and describes the animal's discovery and lifestyle. Most helpfully, it also lists museums where the fossils can be seen, and it does not confine itself to North America: London, Paris, Cape Town, Beijing, Melbourne, and Ulan Bator get noticed, too. The book also has descriptions of some of the world's major dinosaur museums and field sites. Even if you can't make it to the Flaming Cliffs of Mongolia this year, you can learn why it might be worth the trip. --Mary Ellen Curtin
