The fourth illustration in the series of feathered dinosaurs for the book. This is the famous Velociraptor depicted in its native Cretaceous environment of desert Mongolia.
Velociraptor was a small dromaeosaur, or raptor dinosaur, and contrary to its most famous depictions was almost certainly feathered from head to tail. This is no longer based merely on phylogenic evidence, either - as of 2007, reanalysis of the fossil has shown that its posterior forearm contains quite obvious quill knobs.
