Re: [dinosaur] Agressive behavior of the T. rex

Few extant predators will pass up the chance of an easy meal, and they don't 
come much easier than a 
relatively small, slow and non-armoured primate. Although it could be argued 
that a human with the 
technological ability to travel through time might have other technological 
tricks up its sleave.

A more interesting question might be how far a large adult tyrannosaur would 
bother chasing a human-
sized prey item before deciding it wasn't worth the energy expenditure. I 
suspect the answer would be 
bad news for anyone other than a marathon runner.
