Hadrosauroidea

Skeletal mount of Probactrosaurus gobiensis, copyright Greg Goebel.

Belongs within: Iguanodontia.
Contains: Hadrosauridae.

The name Hadrosauroidea has been used for a clade uniting the Hadrosauridae and Ouranosaurus; it is here used for the smallest clade uniting these two taxa as found in the phylogenetic analysis by Norman (2004). Supporting characters for this clade were not explicitly listed. Ouranosaurus nigeriensis was a relatively large ornithopod from the early Cretaceous of Niger, most noted from the relatively long neural spines arising from its vertebrae.
