I believe that the domestic bull *will* run from ordinary predators,
it is just too used to hmans to think of them that way.

Still, your point is well taken, there are exceptions.

In this regard, the film I saw of the wolves taking down a muskox
is again relevent.  The muskox has substantial, even if relatively
small, horn, and can be quite dangerous in a fight.  This is why
the wolves were doing a harrying attack, rather than an outright
charge.  As it was, one of the wolves was injured anyway.  [I suspect
that it was only due to the nearly complete lack of other prey that
far north during the winter that made the wolves desperate enough
to take this risk].

I would say that a T. rex would tend to avoid attacking a healthy
adult Triceratops unless it was desperate.  Besides, Edmontosaurus
and Anatotitan were both almost as common as Triceratops, and far
less dangerous!
