'Lost world of dinosaurs' uncovered in Alaska

The skeletal remains of a new species of duck-billed dinosaur or hadrosaur, that could endure much colder temperatures than previously thought has been found in a remote part of Alaska, the northernmost dinosaurs are known to have ever lived. 'Ugrunaaluk kuukpikensis', which means ancient grazer of the Colville River was a 9 metre long herbivore that endured months of winter darkness and probably experienced snow.

A collaborative team between Florida State University and the University of Alaska Fairbanks has spent the last five years digging in a remote bone-bed of dinosaur remains in the Prince Creek Formation in Alaska.

Kathryn Ryan spoke to Gregory Erickson of Florida State University, who says the discovery 'challenges everything they thought about a dinosaur's physiology'.
