Question: What would fossilized feathers be expected to look like?

["Erik 12345" <erik_12345@hotmail.com>]

[I've posted this once before, but I don't think it got through, so here's 
my second try -- my apologies if it turns up twice.]

I've read the Nature articles on Sinornithosaurus millenii [1] and the new 
dromaeosaurid [2] informally named "Dave", and I would like to make make my 
own judgement about whether their putative (proto)feathers are indeed 
(proto)feathers. I am not a paleontologist, however, and don't know what 
_fossilized_ feathers would be expected to look like and how this look would 
be expected to differ from, say, fossilized fur, etc. Where can I learn 
about such things? References to non-obscure (to non-paleontologists) 
journals, books and web pages would be greatly appreciated, as well as 
direct self-contained answers.

Erik
