A couple of questions



OK, here's a few short questions for those in the know to answer:

1) Pterosaurs: Ornithodira (& thus the sister group to Dinosauria), or Prolacertiformes? If they are prolacertiformes, would that exclude them from the Archosauria?
2) Scleromochlus: What is it? Prolacertiform or a basal ornithodiran? (Or a likely pterosaur ancestor)
3) Protarchaeopteryx robusta: primitive oviraptorosaur like Caudipteryx, or still "incertae sedis"?
