The surprising place where giant dinosaurs incubated their eggs

Finding a fossilized dinosaur egg is exceptionally rare, but finding a stash of more than 250 shell fragments in the chilly southern reaches of the planet is even more surprising. The discoveries come from southernmost Patagonia in Argentina, where giant, long-necked titanosaurs roamed toward the end of the dinosaur era. Previous egg discoveries suggested that these massive beasts usually nested much farther north.
