This is not meant to be a textbook, nor should it be. This is a general overview of concepts and creatures the general public have no idea exist. And this is its purpose.
Our gift shop sold this book for a year, and we use it almost daily in our discussions with patrons. The facial reconstructions, the fossil imagery, the creature stats, all of it comes together beautifully and clearly to teach the layman and casual scientist alike.
Excellent book. I hope to see future editions as we discover more.
