It is below the Ankylosaur crown group of Nodos and Ankylosaurs, thus it
probably should be used to define a new clade aboce Scelidosaurus. It is
included in my cladogram from the Gastonia paper. Both Ken C. and I have
trouble with the Shamosaurines being less derived than Polacanthines, as
they share some significant cranial characters with the ankylosaurines.
But this is the cladogram we get at the moment.
