Favourite dinosaur?

On topic, how do they know it had feathers?
Did they fossilize? Could the feathers have come from prey?
Bones aren't the only type of fossils. You can get trace fossils as well, including imprints - I think they found some imprints around velociraptor skeletons that indicated they were feathered. Also, last year in Mongolia they found a velociraptor skeleton with quill knobs along its arms, which are basically the bumps that the feathers come out of.
There is a line of thought that velociraptors used their feathers much the same way that ostriches do today, to help them change directions while running without losing as much speed. It is doubtful that they could actually fly, however, when you consider their body size and weight compared to their forearms.
Incidentally, my favourite dinosaur would probably be a triceratops. I think this stems from when I used to play dinosaurs with my cousin Eoin as a child, and he was always an allosaurus or some other carnivore while I was the herbivore he was hunting. I think a triceratops comes across as well able to stick up for itself!
How nice is it to be able to discuss your favourite dinosaur without other people calling you a dork?!

Some have even theorized that dromaeosaurs ('raptors') evolved from primitive birds.Bones aren't the only type of fossils.
