Edward Drinker Cope's reconstruction of Laelaps, from PAPER DINOSAURS
The Linda Hall Library of Kansas City, MO hosts a very cool on-line exhibit called Paper Dinosaurs. It is well-worth a few minutes of your time. It's chronologically organized, and all of the images have nice, long descriptions.
From the site:
In 1996, the Linda Hall Library mounted an exhibition of original printed materials related to the history of dinosaur discovery. On view were most of the classic papers of dinosaur lore, including original publications by Gideon Mantell, Richard Owen, Othniel Marsh, Roy Chapman Andrews, and a host of others; there were forty-nine items in all. The original exhibition ran from October 17, 1996 through April 30, 1997.There is a lot of great stuff featured here, from the iconic, such as Robert Bakker's Deinonychus, to the obscure. It's also a good primer on the colorful history of dinosaur paleontology (a subject I fully intend to write more on in the future). If you'd like to order a copy of the catalog from the original exhibition, it is available from the library for the reasonable sum of twelve US dollars.
