Excellent! One question, though -- doesn't _Ankylosauria_ have precendence
for Clade(_Ankylosaurus_ <- _Stegosaurus_). I.e., is the name
_Ankylosauromorpha_ really necessary?

Also, which is more correct?:

+--Polacanthidae
`--Ankylosauridae
   |--Ankylosaurinae
   `--Shamosaurinae

Ankylosauridae
|--Polacanthinae
`--+--Ankylosaurinae
   `--Shamosaurinae

Thanks--
