Re: Doh!
Synapsids aren't reptiles, because Reptilia has been redefined to fit into cladistics.
It looks like the following.
-Amniota
 |_
   |-Synapsida
   |-Sauropsida
    |-Something or another
    |-Reptilia
     |-modern reptiles

Re: Archaeopteryx- most likely fraud, if not, still not transitional
The preserved skin portions are on the legs and the underside of the tail, which are not exactly places where feathers need to be. Now, if skin impressions were found on the arms or back, then it would be a reasonable assumption that Juravenator was featherless.

Re: Doh!
I know Sauropsida is the larger grouping. The last I checked, Reptilia had been redefined as a daughter group of Sauropsida.
