Nanuqsaurus Roamed Late Cretaceous Arctic

In 2014, scientists announced the discovery of Nanuqsaurus hoglundi, a small tyrannosaur that lived in Arctic Alaska about 70 million years ago during the Late Cretaceous Period. Researchers identified it from skull and jaw fragments and estimated that it measured around 7 meters long, about half the size of Tyrannosaurus rex. They determined that the fossils belonged to a mature animal from a new species, not a juvenile from a known species. Its name comes from the Inupiat word "nanuq," meaning polar bear.
