A couple dozen new dinosaurs have been found in western North America. Moreover, paleontologists in South Dakota discovered the most complete Tyrannosaurus rex skeleton ever. The story of "Sue" captivated dinosaur buffs around the globe. Dinosaur discoveries in Patagonia included the vertebrae of one of the largest plant-eaters that ever lived, Argentinosaurus, which may have been over 100 feet long.
