Query: The best book on the subject yet!

You may think me biased, since some of my reconstructions where used in the book, but I did not write any of it (and I don't recieve royalties based on sales). While there are a few nit-picky details I would change, this is easily the best book on how to draw dinosaurs ever made. It is the only one where the reader is given a short anatomy lesson, and shown skeletal reconstructions so artists can learn how to reconstruct extinct animals themselves. It also shows off the remarkable diversity of dinosaurs to good advantage. Highly recomended.
