Speedy tyrannosaurs



>A - hadrosaurs were not THAT much slower than tyrannosaurs

This is certainly lucky for the hadrosaurs, otherwise they might not have
gotten around much. Various folks who study these animals, such as Jim Farlow
and Jack Horner have suggested that the large, heavy tyrannosaurs were slow
moving and not galloping across the landscape like possessed chickens (or 
40-foot roadrunners for that matter). The anatomy of the beasts suggests a
modest top speed. Anatomy, biomechanics, gravity, the inertia of a top-heavy
biped all would seem to suggest that tyrannosaurs were incapable of either a
short-burst or a sustained bout of swift movement.
