Correct me if I'm wrong, but I think Lufengosaurus and Dilophosaurus were
found together (according to the book _Fossil Animals of China_) sort of like
Velociraptor and Protoceratops.  Also, wasn't Afrovenator found associated
with the "camarasaur" and Utahraptor with Pleurocoelus?  Of course,
Tyrannosaurus/Edmontosaurus is supported by the Edmontosaurus tail that was
bitten by a Tyrannosaurus and healed.  

Allosaurus/Stegosaurus is supported by an Allosaurus pubis that has a hole
(and signs of an infection) large enough for a thagomizer spike to fit in.  

There are tons of potential "natural enemies" in the dinosaur world.  Only a
few of them are supported in the fossil record, though.
