A few years ago, fossilized eggshells were found in southern Patagonia, near the southern tip of South America. Eggshells from these giant reptiles have never been discovered so close to the South Pole. 

Paleontologists had questions about the find.  

It looked like these eggs belonged to titanosaurs. But how did they hatch in such a cool climate?

Titanosaurs were the biggest dinosaurs that ever roamed the world. They lived on every continent.
