To do this really briefly:
_Apatosaurus_ is the older term by two years (1877 vs. 1879).
The synonymy of these two genera was recognized as early as 1903.  The
popularity of _Brontosaurus_ grew in large part through politics within the
paleo-community (the great authority and PR machine of the AMNH and H.F.
Osborn, who loved the name "_Brontosaurus_" and (a separate issue) the short
stumpy head for the beast vs. Riggs and others).
It actually WOULD still be possible to resurrect "_Brontosaurus_" (the name,
not the taxon!) if it could be shown that _B. excelsus_ (the type species of
_Brontosaurus_) and _A. ajax_ (the type of _Apatosaurus_) were generically
distinct taxa.

Actually, the main candidate would be _Manospondylsus gigas_, an isolated
centrum from the Hell Creek Fm. almost certainly form _T. rex_.  However,
this is not like the case of _Apatosaurus_ and _Brontosaurus_ (where the
type material of the former is at least represented by multiple elements,
including vertebrae, which have been shown to demonstrate some diagnostic

Nevertheless, if _Tyrannosaurus rex_ were so assailed, you are free to join
me on the barricade in the defense of the King! :-)
