Palaeontologists say they have found dinosaur footprints in the far north of Canada.
The finds prove that dinosaurs were living close to the Arctic, and could be evidence that they were warm-blooded. A team of Canadian and US researchers say they have found three tracks in the Faro-Ross River area of the Yukon. These are the first fossil tracks to be found in the Yukon and only the second record of dinosaurs in Canada's Northern Territories. The discovery was originally made in spring by palaeontologists from the University of Alaska Museum , in Fairbanks. They returned to the area in August to gather more data.
