He's been mythologized and merchandised like no other dinosaur. Does anyone know the real Tyrannosaurus rex- or is he just another misunderstood celebrity? Until recently, everything we knew about this dinosaur king was based on a scanty collection of bones. Thanks to some astonishing new finds, the mighty carnivore's image is changing. Join a museum crew on a suspenseful dig to uncover one of the most complete T. rex specimens ever found- a remarkably preserved skeleton some 40 feet long. Then hear what the scientists have to say about how this mysterious beast moved, killed, and lived- and what kind of cosmic zap it would have taken to make it die. "Understanding dinosaurs takes both science and imagination," one expert concludes. NOVA has its eye on both ends of the spectrum- from the CAT-scan view of a small skull that could identify a new "pygmy" genre of dinosaur to some campy clips of King Kong and other mega-monsters that keep generations of dinosaur lovers entertained.
