Synopsis

The common image of dinosaurs often depicts them in lush, warm landscapes – swamps and jungles teeming with plant life and predator-prey interactions. However, "Arctic Dinosaurs" reveals a different reality: many species also flourished in the challenging environments of the polar north and south. NOVA chronicles two ambitious expeditions, following paleontologists as they venture to the Alaskan tundra to unearth 70-million-year-old fossils, pushing the boundaries of scientific understanding.
