The article appears to be somewhat mistaken, judging by http://ehis.ebscohost.com/ehost/detail?sid=5fc8615c-3e1a-48ac-b123-ae43a468174a%40sessionmgr4&vid=1&hid=2&bdata=JnNpdGU9ZWhvc3QtbGl2ZQ%3d%3d# http://ehis.ebscohost.com/ehost/detail?sid=5fc8615c-3e1a-48a..., http://www.unmuseum.org/dinobront.htm http://www.unmuseum.org/dinobront.htm and http://en.wikipedia.org/wiki/Apatosaurus#History http://en.wikipedia.org/wiki/Apatosaurus#History (the latter two which are barely more reputable). The artificial head wasn't put on the body of the Apatosaurus (the first skeleton), which apparently was never put on display as a full skeleton at all. It was the second skeleton, which he named Brontosaurus and mounted in the Yale Peabody Museum with the wrong head. This story is also more consistent with saying the Brontosaurus "never existed", since it was the Brontosaurus that got given the wrong head. (Though one could well argue that Brontosaurus was just another name for Apatosaurus with the whole head thing just being an error in the visual representation of the dinosaur referred to by Brontosaurus.)
