Dinosaurs in the arctic – plausible. Dinosaurs thriving in the arctic – absolutely crazy…

The notion that dinosaurs were reptilian-esque, scaly, and cold-blooded creatures has probably played a role in shaping the idea that we shouldn’t expect to find dinosaurs at higher (colder) latitudes. But as our picture of dinosaurs has changed (think feathers and possibly endothermic (warm-blooded)) over time, it is probably not that surprising to learn that dinosaurs may have done well in colder (and darker) latitudes.

The discovery of not only adult dinosaurs but their young up in fossil deposits in Alaska tells us exactly that. This means that these dinosaurs were not just migrants moving through these regions but were able to reproduce. The other cool thing? It wasn’t just one, but a large collection of species that had babies represented in the fossil record. This means that a lot of dinosaurs were actually able to reproduce – which suggests that they were well-adapted to polar regions.

Just another lesson in how much we still have to learn about these beasts from the past.
