Researchers have found a perfectly preserved 57,000-year-old 'wolf mummy' in Canada's Yukon.
- The female pup is "the most complete wolf specimen ever found from the Ice Age", according to one scientist.
- So complete, in fact, that even the contents of her stomach were still intact - fish, which researchers say means ancient wolves subsisted on aquatic life rather than bison or other land-based prey.
- Scientists believe the 7-week-old was killed and "freeze-dried" when her den collapsed.
