Dinofact #119
For a long time the type species of Brontosaurus, B. excelsus, was considered a synonym of Apatosaurus, thus making Brontosaurus invalid as a genus. It is still disputed today, with some people saying that B. excelsus is not distinct enough from A. ajax, while others argue that the two are distinct enough to justify Brontosaurus' ''ressurection'' as a genus.
