In 2002, the discovery of a beautiful and bizarre fossil astonished scientists. With four wings and superbly preserved feathers, the creature was like nothing paleontologists had ever seen before. In "The Four-Winged Dinosaur," NOVA travels to the Chinese stone quarry where the fossil was discovered and teams up with the world's leading figures in paleontology, biomechanics, aerodynamics, and scientific reconstruction to perform an unorthodox experiment: a wind tunnel flight test of a scientific replica of the ancient oddity.

There is more research information on this crow sized dinosaur at the APT site. Some portions of the show will be available online.
