Since we now have complete specimens, and since every dinosaur worker
(except for Bakker) agrees that Brontosaurus = Apatosaurus, then it has
ended.  The analogous elements between Apatosaurus and Atlantosaurus are
known, and sauropod experts like Jack McIntosh agree that there is not
sufficient agreement to synonymize the two.

And if it all ended, what would taxonomists do for a living? :-)
