This is a good book but it really wasn't for us. Julia loves learning about dinosaurs but this isn't really set up the way she likes. There are some lesser known dinosaurs included, the Albertosaurus and the Yangchuanosaurus being two examples. Both are seldom covered in childrens books and Julia likes hearing about dinosaurs she knows but doesn't get to learn more about often. I'd say this is more for kids who can read for themselves because it's difficult to "read" facts that aren't in sentences. We have another book in this series that we're also going to read that's about Velociraptor's.
