The southern regions of Argentina and Chile were home to some of the largest dinosaurs to ever roam the planet. This IMAX documentary introduces you to such South American behemoths as the plant-eating Argentinosaurus and its enemy, the predatory Giganotosaurus (which was bigger than a T. rex!), through computer-animated sequences. Paleontologist Rodolfo Coria, the animals' co-discoverer, discusses how they lived and why they died out. Donald Sutherland narrates. 40 min. Widescreen; Soundtracks: English Dolby Digital 5.1, French Dolby Digital 5.1.
