By the way, the feathers in that article date to the late cretaceous period, when birds already existed. I would be interested in knowing how they determined the feathers were not from birds.
That's a good question. There was a temporary exhibit at our science center featuring feathered dinosaurs that I worked at, and it was theorized that the feathers belonging to dinosaurs were more hair-like rather than like the feathers we know of today, and moreso for warmth, that therefore they couldn't belong to birds since they weren't built for flight.
I have an Uncle who's a paleontologist who's actually been to Liaoning in China where it was first discovered, so I'll try to ask him to get more of a definite answer.
