What is risky about reaching up and grabbing a sauropod by the neck, if you
match the physical description of a tyrannosaur? If your hold is 2m behind the
head, you are 8m away from the front feet. Even that assumes no injury to the
spine of the prey item, which would result in instant incapacitation of the
It 'looks like' to me like you are characterizing prey/predator interactions on
the basis of sheer intuition, and are overly impressed by simple size

(While we're mentioning "late-night thoughts"... I was asked if I'd mind
explaining, and I answered "sure". That's not what I meant, obviously.)

Their teeth and their skull biomechanics. Tyrannosaurs look more like they
took time to place a bite in a convenient position and then thoroughly
crunched their prey. This should kill or at least immobilize most animals up
to the tyrannosaur's own size pretty quickly and with a high success rate,
but looks like an unnecessary risk when the prey is twice as long and tall
as the predator.
