Editing Arctic (section)

==Paleontology==
During the [[Cretaceous|Cretaceous period]], the Arctic still had seasonal snows, though only a light dusting and not enough to permanently hinder plant growth. Animals such as the ''[[Chasmosaurus]]'', ''[[Hypacrosaurus]]'', ''[[Troodon]]'', and ''[[Edmontosaurus]]'' may have all migrated north to take advantage of the summer growing season, and migrated south to warmer climes when winter came. A similar situation may also have been found amongst [[dinosaur]]s that lived in [[Antarctic]] regions, such as the ''[[Muttaburrasaurus]]'' of Australia.

However, others claim that dinosaurs lived year-round at very high latitudes, such as near the [[Colville River (Alaska)|Colville River]], which is now at about 70°&nbsp; N but at the time (70 million years ago) was 10° further north.<ref>{{cite journal |title=A paleontologists Alaskan adventure |journal=[[New Scientist]] |date=9 June 2012 |url=https://www.newscientist.com/article/mg21428686-800-a-palaeontologists-alaskan-adventure/ |access-date=30 March 2022 |archive-date=12 April 2022 |archive-url=https://web.archive.org/web/20220412005721/https://www.newscientist.com/article/mg21428686-800-a-palaeontologists-alaskan-adventure/ |url-status=live}}</ref>
