How Dinosaurs Survived the Polar Night

Some dinosaurs never saw the sun for months at a time. These are the polar dinosaurs, and this is how they survived. In this documentary we travel to three lost polar worlds: Jurassic Antarctica, where the crested predator Cryolophosaurus hunted beneath the twilight; the rift valley of Early Cretaceous polar Australia, home of big-eyed Leaellynasaura, the sprinter Timimus and the giant amphibian Koolasuchus; and Arctic Alaska, hunting ground of Nanuqsaurus and Pachyrhinosaurus, where a 2021 discovery of tiny hatchling fossils proved that dinosaurs nested at the top of the world — and suggests they stayed through 120 days of winter darkness. Along the way: fossil feathers from Koonwarra, the hibernation debate, possible dinosaur burrows, and what polar life reveals about warm-blooded dinosaurs. Every episode of Deepmost is built on published science and brought to life with AI-crafted visuals, because no camera can film these worlds. If you made it to the end, tell me in the comments where you're watching from — and whether it's day or night.
