Dinosaurs kept warm — and accidentally survived a mass-extinction event
Paleontologists still debate a number of fundamental questions about dinosaurs. What did they look like? Did they survive freezing winters? How did some survive so many mass-extinction events that sent other large creatures into extinction?
We reported last week on a new study in the peer-reviewed journal Science Advances that offers evidence that Earth's poles froze during the age of dinosaurs — and that dinosaurs lived through the freezing winters. Now, we're sharing more details about the study and how fresh data are helping scientists answer 220 million-year-old questions about how dinosaurs survived some of the most violent cataclysms life on Earth has ever experienced.
