Ugrunaaluk was a duck-billed dinosaur that lived in the ancient Arctic, where it was cold and dark for part of the year. It had a long, flat beak and hundreds of teeth for chewing tough plants. This dinosaur is special because it shows that some dinosaurs could survive in polar regions.51

1

Ugrunaaluk lived in the Arctic about 69 million years ago, when the climate was much cooler than today, with average temperatures around 5 to 6°C.1

2

Most of the Ugrunaaluk fossils found are from young animals, not fully grown adults. Scientists think a whole herd of juveniles may have died together in a flood.1

3

Its name comes from the Iñupiaq language of Alaska. Ugruŋnaq means a grazing animal with grinding teeth, and -aluk means old, so Ugrunaaluk is 'ancient grazer'.1

4

Ugrunaaluk was a close relative of Edmontosaurus, but scientists found enough differences in its skull bones to give it its own name.1

5

The Liscomb bonebed where Ugrunaaluk was found has thousands of bones, mostly from this dinosaur, along with a few teeth from tyrannosaurs and other small dinosaurs.1

6

During the time of Ugrunaaluk, the Arctic had polar woodlands with flowering plants in the understory, and the days were dark for months in winter.1

?Was Ugrunaaluk a duck-billed dinosaur?

Yes, Ugrunaaluk belonged to the hadrosaur group of duck-billed dinosaurs. It had a long, flat beak and hundreds of teeth for chewing plants.4

?Why is Ugrunaaluk special?

Ugrunaaluk is special because it shows that some dinosaurs could survive in polar regions. It lived above the Arctic Circle, enduring months of darkness and cold.4

ጽውጽዋይ ዘፍርስ

ጽውጽዋይ: Ugrunaaluk is just a young Edmontosaurus and not a real separate dinosaur.

ሓቂ: Scientists showed that Ugrunaaluk has unique skull features that make it a distinct species, even when accounting for age differences.1
