New here, General Qs

["Bradley Fischer" <fischb22@hotmail.com>]

Greetings all,

My name is Brad, a pilot by profession and like everyone else here, 
fascinated by dinosaurs. So some general questions regarding, yes, T-rex.

I've read the archives, and I've noticed the question of Tyrannosauridae 
predation has been debated many times and I have found the counter arguments 
to Horner's theory of scavenging to make sense to my limited understanding 
of zoology. I am curious about the reason for the very large Olfactory lobe 
on T-Rex's brain. So my questions revolve around this area:

1. How does this area of the brain compare with other Tyrannosaurids and the 
evolutionary forebears?

2. How does T-Rex brain structure compare with Dromeosaurs and other small 
theropods?

3. Do modern predators have large olfactory lobes? I note that Dr. Holtz's 
pursuit and bite theory and he compares T-rex to wolves. Canids 
traditionally have a very keen sense of smell and I am hoping that someone 
here can discuss the size the olfactory lobe on canids as well.


On a different topic: In a fairly recent issue of Scientific American, there 
is an article about the evolution of feathers and their beginnings on 
theropods. The article suggests that even T-rex probably was feathered.  
Only problem I have with this theory is that the subject sample is all from 
china and they found no large theropods with feathers. Anyone care to 
comment on this? Am I off on my thinking?

Regards,
Brad
