Season 36

Most people picture dinosaurs roaming warm climates—swamps and jungles—feasting on vegetation and sometimes on each other. Yet Arctic Dinosaurs reveals that numerous species also thrived in the brutal polar environments of the north and south. NOVA follows two high-stakes expeditions and the paleontologists who push the boundaries of science to unearth 70-million-year-old fossils buried beneath the vast Alaskan tundra.
