For the first time in 65 million years, innovative imaging technology enables viewers to see deep inside the body of a dinosaur to reveal the secrets of these ultimate prehistoric survival machines. Combining cinematic photo-real 3D graphics and leading-edge anatomy and paleontology, "CLASH OF THE DINOSAURS" peels back the skin, muscles and bones to show how they survived in such a violent world. The four-part special premieres on Discovery Channel Sunday, December 13 at 9PM E/P with double-stacked episodes. (Source: Discovery)
