Feather Anchors

Feather Anchors
From top, a view of the right ulna of a Velociraptor is shown. Next, a detail from the bone cast is shown with arrows pointing to six evenly spaced feather quill knobs. Next, a view of a right ulna of a turkey vulture (Cathartes) and, at bottom, the same view of a turkey vulture but with soft tissue dissected to reveal placement of the secondary feathers relative to the quill knobs.
