Hadrosauromorpha
Extinct clade of ornithopod dinosaurs
Hadrosauromorpha is a clade of iguanodontian ornithopods, defined in 2014 by David B. Norman to divide Hadrosauroidea into the basal taxa with compressed manual bones and a pollex, and the derived taxa that lack them. The clade is formally defined in the PhyloCode as "the largest clade containing Hadrosaurus foulkii, but not Probactrosaurus gobiensis".

Hadrosauromorpha is a clade of iguanodontian ornithopods, defined in 2014 by David B. Norman to divide Hadrosauroidea into the basal taxa with compressed manual bones and a pollex, and the derived taxa that lack them. The clade is formally defined in the PhyloCode as "the largest clade containing Hadrosaurus foulkii, but not Probactrosaurus gobiensis". This results in different taxon inclusion depending on the analysis.
