           No, I don't.  With modern prey/predator relationships (when the
prey animal is many X's larger than the predator)
        it is the very young, the very old, the sick, trapped, or injured
who are selected.  It's simply not in the best interest
        of a predator to risk serious injury attempting to take down an
enormous prey animal.  Now, I'm NOT saying that predators never act out of
desperation, but these don't represent their normal hunting patterns.  A
species survives as a successful predator in large part because they are
good at exploiting their niche in the environment.

           Yes, I'd say I agree with that - in the main.  Now, IF we find
substantial evidence of cooperative hunting techniques among carnivores
dinosaurs, I would find the "preying on VERY large animals" idea more


        P.S.: Thanks for all of the other folks for the corrections of
"predated", I needed a good chuckle last night;
        it's "performance appraisal" time here!  Grrrrr... :-)
