Re: late night thoughts: not all T. rexes were adults

If it were picking on animals it's own size, it would be as fast or
faster than them - they couldn't gallop out of sight.
And where's this mega-tall, long-tailed monster supposed to be hiding?
They'd need a lot of large and thick bushes! Also, duckbills and
ceratopsians probably had better acceleration than /rex/, because of
their shorter limbs and lower CG -- rexy would have to make sure they
came _damn_ close before trying to bite 'em.
So, I ask, what does it look like /T. rex/ could do better than it's
prey? Long-distance, efficient walking is my guess. I don't know the
energetics of the situation, but shouldn't think a walk of a few miles
would be a huge problem for a healthy /rex/, and it would only need a
small margin on its prey to catch up on them.
