RE: Stormbergia dangershoeki, new Early Jurassic ornithischian from South Africa

[Jay <sappororaptor@yahoo.com>]

 Was Genasauria an apomorphy based taxon (all ornithischians possessing a 
cheeck) or a defined as
(Thyreophora + Cerapoda)?  If it was the first definition, doesn't that disolve 
Genasauria?.  

I also noticed in the Butler's cladogram, Sceildosaurus is nested with 
Ankylosauria, supporting
Carpenter's Ankylosauromorpha.
