With no disrespect at all meant to Dr. Norman, we don't really need new
ornithischians to figure this out... as he points out with
Heterodontosaurus, reexamination of the old ones is sufficient to rock the
boat. It is productive, in this context, to ask: how many actual analyses of
Ornithischia ARE there? One of the many reasons to adopt a more circumspect
approach to the phylogenetic nomenclature of ornithischians...
