Re: Greg Paul is right (again); or "Archie's not a birdy"

There was no way that small armed Epidexipteryx flew. But its actual 
phylogenetic placement is tenuous and it may have descended from Jurassic 
I doubt we will ever be able to sort a lot of this out. In any case my basic 
notion was that Archaeopteryx was less derived than some "dinosaurs," and 
that some of the latter were secondarily flightless, which seems to be 
holding up pretty well.

That doesn't fit your theory, correct? >>
