Feathered dinosaur

Feathered dinosaur
When his Chinese colleague Ji Qiang first showed Mark Norell this fossil in 1999, Norell thought it was the greatest dinosaur specimen he had ever seen. The feathers on this small dinosaur, which Norell affectionately calls "Dave," are much more pronounced than those on the "first feathered dinosaur," Sinosauropteryx prima. Dave's feathers also come in three types: simple hair-like fibers (primarily on the head and tail), sprays of fibers (apparent on the hind limbs and shoulders), and asymmetrical feathers like those of a modern bird (on the trailing edge of the arm).
