"Intrepid paleontologists discover dinosaurs that thrived in the Arctic’s cold and dark.
A team of intrepid paleontologists discovers dinosaurs that thrived in the unlikeliest of places—the cold and dark of winter in the Arctic Circle. How did they survive year-round and raise their young in frigid and dark winter conditions? A dinosaur expedition explores a remote, treacherous, and stormy terrain where the team knows that every bone they find there will likely be a first, adding up to a unique picture of a lost northern world."
