This video is part of a series that examines the world of dinosaurs. Hosted by actor Jeff Goldblum, the series looks at the giant creatures who roamed all areas of the earth, and whose sudden disappearance remains a topic of scientific debate. Was Immanuel Velikovsky right in his theory about the disappearance of the dinosaur? Where is the real Jurassic Park? These and other questions are presented in the video, with computer graphics and 3-D animation that re-create the world in which the dinosaurs lived.
