Surprisingly, this is not necessarily true.  Turns out (as I
discovered when preparing the Cetiosaurus petition) that there is no
such thing as page priority under the ICZN.  It used to exist in
earlier versions of the code, but not any more.  First reviser gets to
decide which name wins in cases like this.  (Page priority does live
on as a non-mandatory convention that first revisers often follow; I
wonder how often that's because the reviser thinks that it's a rule!)
