We know dinosaurs reached the Arctic.
But did they stay year-round… or just migrate?
The answer came from something tiny: newborn fossils.

We know what killed the dinosaurs.
We know where it hit.
But here’s the question we almost never ask:
When, within the year, did the asteroid strike?
New evidence suggests it was spring.

The planet cooled, ice sheets grew, sea levels fell, and shallow seas disappeared.
