Saurolophidae was also used as a clade inside Hadrosauridae in a previous paper
(Prieto-Marquez & Wagner, 2009). I thought it was odd here too.
As Tom says, Euhadrosauria is available for the more inclusive clade (called
Hadrosauridae by Prieto-Marquez). However, there is no reason why a clade that
is defined to include _Hadrosaurus_ could not simply be called 'Hadrosauria'.
In other words, Hadrosauridae would be re-named Hadrosauria, which would
Interestingly, Prieto-Marquez (2010) recovers _Lambeosaurus laticaudus_ as the
sister taxon to _Hypacrosaurus_; so the new combination _Hypacrosaurus
laticaudus_ may be in order for the Mexican hadrosaur.
