Dimetrodon had a sail, but other spenacodonts did not.  The lack of a sail
does not exclude members from this group.

Read the paper that was just released on Baryonyx.  The authors are
certainly the authorities on the subject and they see a relationship.  By
the way, Spinosaurus might only be barely late Cretaceous.  It is listed as
late Albian-early Cenomanian.  It could also be an early Cretaceous animal.
 Baryonyx is Barremian, so it is certainly older, but a contemporary of
Becklespinax (not Altispinax, whom you refered to earlier.  Altispinax is
known only from three teeth).
