"All existing evidence indicates that dromaeosaurids were covered in thick feathers. This holds for all dromaeosaurids, from Graciliraptor to Utahraptor, including those whose fossils bear no traces of intigument due to unfavourable fossilization processes. I'd like to point out that the alternative to the feathered model, that is, the hypothesis that big dromaeosaurids lacked feathers or were even scaley like crocodiles, is blatantly anti-scientific, seeing as unlike the feathered model it is not based on either any anatomical evidence or on known zoological phenomena (there is no proof whatsoever of feathered animals evolving into scaley ones). Dromaeosaurids belong to Maniraptora, and no maniraptoran fossil discovered so far has ever shown traces of scales. On the contrary, all feather impressions found so far belong to maniraptoran skeletons, including some dromaeosaurids. Overall, the data supports with undeniable proof the feathered model."
