Ugrunaaluk kuukpikensis, such is his (unpronounceable) name. The term means “old grazer of Colville River” in the dialect of the Inupiat Eskimos in northern Alaska. It is in this US state that lived Ugrunaaluk kuukpikensis – pronounced (oo-nah-luk-GROO’ KOOK’-pik-en-sis) from The Daily Beast – a dinosaur whose discovery was made public by researchers in Alaska and Florida, September 22.
A “duck-billed dinosaur”
This is a hadrosaur or “duck-billed dinosaur”, a “type very herbivores present in North America, Asia and Europe in the Late Cretaceous (from – to 100 million years – 66 million years ago). “says Le Monde It is in a layer of 69 million years of the Prince Creek Formation that some 6,000 bones were found.
The skull and the rest of the skeleton of the dinosaur were then recomposed through 3D printing, as seen above. The fossils found probably belonged to a herd of Ugrunaaluk kuukpikensis juveniles from 1 to 3m. But adult, this cousin of the dinosaur Edmontosaurus could measure up to 9m.
“Alaska is our last frontier”
According to scientists, the herbivore walked on its hind legs and ate mostly thorns This coniferous forest region, then located more to the north. “Even if the earth’s climate then was warmer, winters would be cool (6 ° C on average) and sometimes snowy night and almost permanent,” said Sciences et Avenir.
Advanced size for experts because until now it was thought the dinosaurs unable to survive the cold. And Ugrunaaluk kuukpikensis might not be the last dinosaur called in this region where paleontologists have discovered a dwarf Tyrannosaurus. For one of the team of scientists, “Alaska is our last frontier.”
