My 11 month old son loves this book, and Farmyard Hullabaloo and Commotion on the Ocean. He seems to enjoy the rhymes and obviously loves the colourful, fun illustrations that are so mucha trademark of this series. This book has prompted many 'discussions' with my son about dinosaurs and I've spent many evenings checking things that have come out of our 'chats' on the internet. It certainly seems to be factually correct in most repects as well as having fun, silly rhymes that are easy to read and remember.
