Itemirus may be a primitive ancestor to the tyrannosaurids.  Aublysodontids
are the primitive tyrannosaurids.  Dryptosaurus is a basal coelurosaur.
Baryonychidae is a junior synonym of Spinosauridae, and spinosaurids are
probably megalosauroids (primitive tetanurines).  Archaeornithoides is
almost certainly a maniraptoran.
