The Ultimate Dinosaur Book by David Lambert, John H. Ostrom
Synopsis:
In-depth profiles of 55 species from every dinosaur group, illustrated with pictures of models and anatomy, offer the paleontological insights into dinosaur posture and gait, musculature and internal organs, behavior, and the reasons for extinction. The very best in graphics visualization. John Ostrom was the first scientist to posit convincingly that some later dinosaurs had temperature regulation. Astounding? Well homeotherms started somewhere, didn't they?
