Very well illustrated, with drawing's of environmental scenes that include dinosaurs, maps that displayed the location's of dinosaur bones, and diagrams that demonstrate particular charateristics of their feathers and bones. A section discusses the work of Paleotontologist's in nice detail and other sections define various known biological features of dinosaurs, including diet and size. There are many fold out pages that demonstrate bigger and colorful diagrams that are eye appealing. I would recommend this book to anyone who wanted to know the very basics of dinosaurs in an easy to understand way. I would include a book such as this one in a lesson on evolution. The author demostrates accurate information, such as with the time frames of dinosaurs existance and their various physical features. It was organized beautifully, with a contents page, glossary, index, bibliography, and other suggested informational resources.
