Skeletal mount of Edmontosaurus annectens, copyright Andytang20.


Belongs within: Hadrosauridae.

The Hadrosaurinae are a lineage of hadrosaurid dinosaurs that are mostly crestless, or possess a solid crest formed from an extension of the nasal bones. The clade as given below is supported by the presence of a caudal margin on the circumnarial fossa (Horner et al. 2004).
