I'll say.  The *current* rules say that a name proposed in
synonymy is *not* validly published.  Of course, there is the
issue that the current rules were not in effect at the time,
and so it may well have been properly published then. Still the
Commission is hardly going to sink a well-established genus
like the dinosaur Centrosaurus for such a weakly established name.

So, there seems no reason not to continue using the name Centrosaurus
pending a more final resolution.
