Utahraptor, Velociraptor and Microraptor were feathered raptors. Dinosaur researchers found quills on the arms of a Velociraptor, even flight feathers on Microraptor. They believe that Utahraptor had feathers too. However, none of the three was actually able to fly.
Microraptor weighed at most one kilogram, Utahraptor around 500 kilograms.
