We have read quite a few dinosaur books by now, and this one stands out as a good beginner's book: It is short (20 pages) and can thus be read in one sitting, it has simple vocabulary so it can probably be easily read by a six year old. It is not encyclopedic in form, such as for instance the [b:Pocket Genius: Dinosaurs|16062296|Pocket Genius Dinosaurs Facts at Your Fingertips|DK Publishing|http://d.gr-assets.com/books/1365480487s/16062296.jpg|21850549] or [b:Dinosaur Detectives|17792091|Dinosaur Detectives|Belinda Gallagher|http://d.gr-assets.com/books/1365709660s/17792091.jpg|24885642], rather focuses on a handful of dinosaurs and important aspects of their features, illustrated by little diagrams, also including a few interesting general facts. My kid was enchanted by the format of this book and asked to get the rest of the books from this Eye Openers series. ( )
