Editing Velociraptor (section)

===Feathers===
In 2007 Alan H. Turner and colleagues reported the presence of six [[quill knobs]] in the ulna of a referred ''Velociraptor'' specimen (IGM 100/981) from the Ukhaa Tolgod locality of the [[Djadochta Formation]]. Turner and colleagues interpreted the presence of feathers on ''Velociraptor'' as evidence against the idea that the larger, flightless [[maniraptora]]ns lost their feathers secondarily due to larger body size. Furthermore, they noted that quill knobs are almost never found in flightless bird species today, and that their presence in ''Velociraptor'' (presumed to have been flightless due to its relatively large size and short forelimbs) is evidence that the ancestors of dromaeosaurids could fly, making ''Velociraptor'' and other large members of this family secondarily flightless, though it is possible the large wing feathers inferred in the ancestors of ''Velociraptor'' had a purpose other than flight. The feathers of the flightless ''Velociraptor'' may have been used for display, for covering their nests while brooding, or for added speed and thrust when running up inclined slopes.<ref name=Turneer2007/>

Because of the presence of another dromaeosaurid in Ukhaa Tolgod, ''[[Tsaagan]]'', Napoli and team have noted that the referral of this specimen to ''Velociraptor'' is currently subject to reexamination.<ref name=Napoli2021/>
