The Allosaurus and Barosaurus dinosaur mounts in a dramatic staged face-off in the Theodore Roosevelt Rotunda. In a dramatic representation of an imagined prehistoric encounter between predator and prey, a Barosaurus rears up to protect its young from an attacking Allosaurus. The enormous Barosaurus is the world’s tallest freestanding dinosaur mount, and composed of casts of real bone, since fossils are too heavy to support in this way.
