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.
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."
Now I'm not saying I just dug a hole to China trying to find a hibernating dinosaur, but I am riding in a rickshaw and we did just hit a flying cat.

Thanks to Matt, who is training one of those truffle-sniffing pigs to find dinosaur burrows.
