Exactly how does a tyrannosaur "turn on a shoulder"? Besides, it
wouldn't make it any lighter. Most predators don't weigh five or six
tonnes. Dropping a large elephant from six feet or so feet in the air
would probably not do wonders for its health, particularly if you toss in
about fifteen to twenty mph of forward momentum.
