Dinosaur Hall is filled with examples of these magnificent creatures from
throughout their history. Today dinosaurs are often seen as symbols of
evolutionary failureâ€”after all, arenâ€™t they extinct? Yet dinosaurs of
marvelous variety, size and complexity roamed the earth for 150 million
years, in reality one of natureâ€™s great success stories. Today, the
descendants of the dinosaurs still surround usâ€”we know them as birds.
