Re: sub-orders

Ranks like orders and suborders aren't thought to be useful by many
paleontologists anymore (plenty of people here will go into depth about that
if given the chance), but a modern classification going down to traditional
"suborder" level might be something like-

Saurischia
------Eoraptor
------Herrerasauridae
------Theropoda
-------------Guaibasaurus
-------------Coelophysoidea
-------------Dilophosaurus
-------------Ceratosauria
-------------Megalosauroidea (=Spinosauroidea)
-------------Carnosauria
-------------Coelurosauria (including Aves)
------Sauropodomorpha
-------------Saturnalia
-------------Thecodontosaurus
-------------Efraasia
-------------Prosauropoda
-------------Sauropoda
Ornithischia
------Pisanosaurus
------Lesothosaurus
------Thyreophora
-------------Scutellosaurus
-------------Scelidosaurus
-------------Stegosauria
-------------Ankylosauria
------Ornithopoda
------Heterodontosauridae
------Marginocephalia
-------------Pachycephalosauria
-------------Ceratopsia

Of course, the reality is a lot more complex-
