The species uncovered include duck-billed dinosaurs called hadrosaurs, horned dinosaurs such as ceratopsians, and carnivores like tyrannosaurus Dinosaur species large and small made the Arctic their year-round home and probably developed wintering strategies like hibernation or growing insulating feathers, according to a new study.
The paper, published Thursday in the journal
Current Biology, is the result of more than a decade s worth of painstaking fossil excavations, and puts to rest the notion that the ancient reptiles lived only in hotter climes.
A new study suggests dinosaurs might not have been as cold-blooded as we thought

Dinosaurs are often depicted as large beasts roaming through tropical forests or across hot deserts and the humid jungle of
Jurassic Park may have gone a long way to solidify those images.
Current Biology contradicts those ideas. It suggests that these creatures also lived year-round in what’s now northern Alaska, where they endured freezing winters, snow, and months of darkness.

Paléontologie: Les dinosaures ont également prospéré en Arctique
Certaines espèces de dinosaures s’étaient adaptées aux conditions extrêmes de vie de l’Arctique, montre une nouvelle étude.

Des espèces de dinosaures avaient fait de l’Arctique leur lieu de vie permanent, et probablement développé des techniques comme l’hibernation ou des plumes pour survivre au froid, selon une nouvelle étude. Ces travaux, publiés cette semaine dans la revue Current Biology, sont le résultat de plus d’une décennie de fouilles pour extraire des fossiles, et battent en brèche l’idée que ces reptiles ne vivaient que sous des latitudes plus clémentes.
