Re: Roadrunners/dinos/and so forth

The reason for asking about relative size of prey is that previous threads had 
"mammalised" predatory dinosaur behaviour.  So it
seemed logical to look at extant dinosaur behaviour.  The problem is that most 
extant carnivorous dinosaurs fly off with their prey,
something that T rex could not do, and this limits the size of the prey.

This also affects feeding stragey, i.e.swallow whole rather than dismember.
