Olfactory Lobes & Large Yixian Theropods (was Re: New here, General Qs)

2. How does T-Rex brain structure compare with Dromeosaurs and other small
I recall a post awhile back on the Dinosaur Mailing List that mentions an
SVP abstract that discusses how avialans supposedly have reduced olfactory
lobes. _Tyrannosaurus bataar_ is described as having large olfactory lobes
(Maleev, 1965). _Giganotosaurus carolinii_ appears to have moderately sized
olfactory lobes (Coria & Currie, 2002).
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?
Sadly, there are not yet any large theropods recovered from the Yixian
Formation. Come to think of it, off hand, I can't think of any large
vertebrates from the Yixian. If there are, could someone please list them
with length and mass estimates?
