Re: T.rex predation

[Mark Sumner <range@inlink.com>]

That's actually not a bad way of looking at it.  If T. rex was not a
predator, then what was the primary predator of Triceratops and large late
K hadrosaurs?  Is there another handy candidate?
 
Saying that T. rex was a scavenger and the other tyranosaurs were
predators seems like something of a stretch.  T. rex doesn't seem to be
diverging from the path that the tyranosaurs followed from their
inception -- ever bigger bodies to hold up ever bigger heads armed with ever
larger teeth.
