The website of the American Museum of Natural History describes the scene in the Theodore Roosevelt Rotunda.

At its center, the Theodore Roosevelt Rotunda features an iconic dinosaur exhibit: a dramatic representation of an imagined prehistoric encounter: a Barosaurus rearing up to protect its young from an attacking Allosaurus. The Barosaurus skeleton, which is the tallest freestanding dinosaur mount in the world, is composed of replica bones cast from actual fossils, which would be too heavy to support in this fashion. As part of the restoration of the Theodore Roosevelt Memorial, this display mount was divided in two, allowing visitors to walk between the famous combatants for the first time.
