_Brontosaurus_ is a valid name -- it's just widely (almost universally)
considered a junior subjective synonym of _Apatosaurus_.
A _nomen oblitum_ is, as I understand it, is a name that has become invalidated
1) utter lack of use for a certain time period (I think 50 years, and I think
_Manospondylus_ is an example)
2) official ruling (e.g., _Rioarribasaurus_)
Although maybe it only applies to the first case....
