Description:Our 5 year old is dinosaur crazy right now and this was the perfect gift for him. We love the fact that the illustrations place the dinosaurs in various habitats. Our family finds it facinating to see all kinds of dinosarus in action in the forest, the desert, or my personal favorite, threading their way through a traffic jam in NYC! It gives great perspective on size and behavior. The language is a little advanced but that doesn't seem to dissuade our son from loving this book and it's a great way to expand vocabulary. Plus, it's nice to have something that grows with your child a bit. This book will be around in our house for a good while I'm guessing. Note: it's big and not the easiest bedtime read given it's size. It's more of a sit at a table or on the sofa and read kind of book.
