A 6-foot-long mechanical T. rex model that walks in place, illustrating how biomechanical studies have helped paleontologists learn more about the typical speed and gait of a rampaging tyrannosaur.

Spectacular displays of dinosaur casts, from the threehorned Triceratops to the dome-headed Pachycelphalosaurus, accompanied by details from the latest theories about how peculiar features including horns, frills, crests, and domes were used in life.
