Re: Where are the basal ornithischians...
Quoting David Peters <davidrpeters@earthlink.net>:
Where are the basal ornithischians with a predentary and without a
retroverted pubis?
Maybe there weren't any. Maybe the pubis went first. But I think
_Pisanosaurus_ has been reconstructed in the way you describe (for what it's
worth).
