1) Can a cat such as a felis domesticus or a felis leo gallop
by this same measurement?
2) Do we have a good estimate of the actual mass of a rex - i.e.
have we included the weight-saving features that rex's avian
characteristics would imply was present?
3) Does the rex bone structure imply it is of the same strength
level as hadrosaur or ceratopsian bone?
