Dinosaurs Went Underground to Wait Out Extreme Weather

Sure, the dinosaurs went extinct. But to hang around for 165 million years, they must have known a thing or two about survival.

The recent discovery of the oldest known dinosaur burrow reveals one way polar dinosaurs adapted to extreme conditions—by going underground.

"That's one of the fascinating aspects of polar dinosaurs, we have to put them in settings where there might be snow, ice, and darkness for long periods of the year," said Emory University paleontologist Anthony Martin.

Martin discovered the 110-million-year-old burrow on Australia's southeastern coast, an area once adjacent to Antarctica (map of Earth a hundred million years ago) and rich with polar dinosaur bones.
