This is fine.  Except that Prieto-Marquez also throws in clade Saurolophidae, 
inside Hadrosauridae.  I don't quite see the point of Saurolophidae - 
especially when Saurolophidae is a clade inside Hadrosauridae.  I agree with 
Daniel that this might cause a nomenclatural mess, for the exact reasons he 
gives.
