Dinos Burrowed Underground In Cold Weather

The world's oldest known dinosaur burrow, recently discovered on the southeast coast of Australia, suggests that some dinos went underground to escape extreme weather.

110 million years ago, when this burrow was dug, the southeastern coast of Australia was adjacent to Antarctica.

The burrow is strikingly similar to another one found in Montana in  2005, which held the remains of a 96-million-year-old dinosaur family.

"Right now burrowing dinosaurs might look like an exception to the rule," he said. "But I wouldn't be surprised if more species [dug burrows]. Ten years from now it might be considered commonplace."
