[edit] Monophyly of Hypsilophodontidae
The page http://www.taxonsearch.org/dev/taxon_edit.php?Action=View&tax_id=172 labels Hypsilophodontidae as active, based on the definition by Sereno (1998), which defines this family to include "all euornithopods closer to Hypsilophodon than to Parasaurolophus".

[edit] Hexinlusaurus, a non-ornithopod ornithischian
Barrett et. al. (2005) showed Hexinlusaurus to be outside of Ornithopoda and placed it as Neornithischia incertae sedis. For this reason, remove Hexinlusaurus from this page.
