RE: Feathering in coelurosaurs
First, I wrote:

To which martinh replied:
Given that we are looking at an animal several metres tall, I would think
that the skin surface would offer plenty of "canvas" for display, without
the need for feathers as well.
Note that large dinos such as _Torosaurus_ also had plenty of "canvas"
surface area, but instead it developed a huge frill as a means of display.
Also, today's modern elephants have plenty of surface area that could be
used as a sexual "billboard" but they make no use of it. Simply because a
certain animal has a lot of skin doesn't mean it will use it as a means of
display. So, despite having a large flank, tyrannosaurs could have still
sported a least _some_ type of feathery integument (perhaps around the head
But, as an aside, note that there has been tyrannosaur skin impressions
found in Alberta that may have a completely neutralizing effect on what I
just said (see: http://www.dinosauria.com/jdp/trex/skin.htm).
Man, I hope that made sense. It's hard to word things right when you're in
a rush to get your homework done.
