Yes! Excellant site , was sent to that site myself by...(B.Cunningham??) in
a quest for possible early Ptero-bird ancestor. Thought Cosesaurus might
make a good canditate,
once thought to be avian, now thought to be pterosaur ancestor. Got
Ellenberger`s original description (thanks Tracy Ford),...don`t read french,
but it looks promising!

I`ll go along with it. So,...now I`m really thinking that Archosaurs
themselves evolved out of the direct line  from Prolacertiform to
ptero-bird. Why not?
