NOVA | The Four-Winged Dinosaur | PBS

Duration: 53:19 (Full Program)
Program: NOVA #3502
Broadcast Date: Feb. 26, 2008

Long ago in the age of dinosaurs, a volcano in eastern China erupted and buried a host of strange creatures in ash, creating exquisite fossils that preserved a big surprise--many dinosaurs were covered in feathers. In The Four-Winged Dinosaur, NOVA investigates the most bizarre of these feathered dinosaurs, which has rekindled a fierce, decades-long debate over the origin of bird flight.
