A 6 -10 tonne adult tyrannosaur likely wasn't agile enough to avoid a well-placed kick, tail slap or neck
bump from an adult sauropod either.
The sauropod would not only have the advantage of mass, but also of stability (four legs verses two). A
non-fatal glancing blow from a tyrannosaur would be unlikely to knock a large sauropod over (or even faze
it much), whereas a glancing blow from a large adult sauropod could completely topple a multi-tonne
biped, resulting in an incapacitating injury that might ultimately prove fatal to the predator.
Even if tyrannosaurs attacked as a group, with younger and more agile members harrying the adult
sauropod to exhaustion until the adult tyrannosaurs dared to approach to finish the prey off, there would
still have been the problem of separating the sauropod from its herd members first. Otherwise the
tyrannosaur group would lose their numerical advantage. A sauropod that was already sick or injured in
some way might lag behind the herd and become vulnerable to such a coordinated attack, however a
health adult sauropod accompanied by other healthy adult individuals would likely have been all but
immune to predation.
