Query: Less a play book than an educational one

My five-year-old son thoroughly enjoys this book -- not for the mazes, but for the information it provides. And the title is a bit of a misnomer -- the book also features pages on prehistoric animals such as sabre-tooth tigers and wooly mammoths.One negative: the book is often difficult to open and flatten because of its original packaging in a plastic decanter shaped like a bone. My son's already crying about pages falling out. Also, one editorial nit (from my son): Deinonychus was 7 feet tall, not 7 inches.
