Scientists Unearth Baby Dinosaur Fossils in a Remote Corner of the Frozen Arctic

Key Points:
- Fossils of baby dinosaurs, some as small as a fingernail, found in northern Alaska suggest certain species lived and nested year-round in the Arctic about 70 million years ago, enduring freezing temperatures and months of darkness.
- These fossils, from at least seven dinosaur species including Hadrosauridae and Tyrannosauridae, were discovered at the Prince Creek Formation and represent very young individuals, indicating local hatching and rearing rather than seasonal migration.
- The study challenges the long-held belief that dinosaurs migrated south to avoid harsh Arctic winters, as the long incubation periods and timing of hatching during the onset of winter would have made migration for newborns highly unlikely.
- The Cretaceous Arctic was cooler than today but
