A plant-eating dinosaur uncovered in northern Alaska has been found to be a distinct species from dinosaurs elsewhere.
The dinosaurs grew up to nine metres long and had hundreds of teeth to help them chew coarse vegetation.
Alaska and Florida university researchers say the find – the fourth dinosaur unique to the Arctic regions of Alaska – could change how we view dinosaurs ability to live in colder regions.
The Arctic-adapted dinosaurs that lived 69 million years ago appear to have endured conditions far colder than we usually associate with dinosaurs.
