Greg Paul gave it up much earlier than I did. But Phytodinosauria is still
the best way to organize the herbivorous dinosaurs; ornithischians are most
closely related to and probably descended from very basal sauropodomorphs, as
shown by tooth shape, digital formulae, and various other cranial and
postcranial features. Big problem is that we don't have enough remains of
early ornithischians to make the link more solid. Segnosaurs could have
helped join the groups; they had many of the right anatomical features, but
these must now be considered homoplasies.
