Take a look at Jack Horner's paper on the new species of Prosaurolophus
(1992), wherein he notes that he cannot be certain whether Hadrosaurus is a
hadrosaurid(!). Of course Hadrosaurus is a hadrosaurid by definition; the
problem we have is to decide whether all those other duckbills are
hadrosaurids!
