Dinosaurs In Arctic

Dinosaur species large and small didn't just pass through the Arctic -- they made it their year-round home and probably developed wintering strategies like hibernation or growing insulating feathers, according to a new study.

A pint-sized tyrannosaur braved the frigid Arctic and feasted on fellow dinosaurs 70 million years ago, according to a report Wednesday on a new species identified from fossilized skull bones in Alaska.
