The Four-Winged Dinosaur

NOVA: Palaeontologist Mark Norell travels to China to explore sensational fossils from Liaoning Province in this NOVA presentation. One dinosaur has the remains of a recently eaten mammal in its gut, and there is also a mammal with the remains of a dinosaur in its gut. There is a small dinosaur curled up for a nap, perhaps caught sleeping by a volcanic ash fall. Most intriguing of all, there are numerous dinosaurs with feathers, including what appears to be a feathered ancestor of Tyrannosaurus rex.
