If you enjoyed the incredible television series of the same name, then you simply have to add this book to your library. Just for good measure, after watching the series and buying the book, I then bought the TV series on video! Of course a great deal of guesswork has gone into all this, because we can never know for sure what colour these creatures were or exactly what sounds they made, but the producers have done a great job working within the limits of the info available to them such an unimaginably long time after the event. The book is a feast of fascinating photo's and must make anybody wonder about these animals who ruled the world long before man. If this book doesn't make a dinofan out of you, nothing will!
