I came across this great post today at Love in the Time of Chasmosaurs. If you have not discovered it yet, I suggest you check it out. And if you can, join and submit some Vintage Dinosaur Art to the Flickr Group!

This is from page 403 of Prothero & Dott Jr.'s Evolution of the Earth Textbook. If I could scan the cover, featuring one of the most amazing Amarghasaurus art of all time, I'd get that in there, too.
