Brontosaurus is an invalid name for Apatosaurus excelsus. Apatosaurus didn't live in swamps; they lived in semi-arid plains. The reason that they are frequently associated with swamps is because when they were first discovered, it was believed that sauropods would be unable to support themselves on dry land, and that they must have spent their lives at least partially submerged in the water of swamps. This is now known to be completely false.
