 Baryonyx?? >>

You're absoluteley right.  I think the relationship between Spinosaurus and
Baryonyx cannot be substantiated at this point.  In fact, I never even though
of the two being together before.  The spines on Spinosaurus's back must be
in common with other "Spinosaurs", right?  And Baryonyx has the heavy hand
claw that is absent in Spinosaurus.  They do have similar jaw structures, but
that's about it.
