Blue Babe is the 36,000-year-old mummy of a male steppe bison which was discovered north of Fairbanks, Alaska, in July 1979. The mummy was noticed by a gold miner who named the mummy Blue Babe – "Babe" for Paul Bunyan's mythical giant ox, permanently turned blue when he was buried to the horns in a blizzard (Blue Babe's own bluish cast was caused by a coating of vivianite, a blue iron phosphate covering much of the specimen). Claw marks on the rear of the mummy and tooth punctures in the skin indicate that Blue Babe was killed by a cave lion. Blue Babe appears to have died during the fall or winter, when it was relatively cold. The carcass probably cooled rapidly and soon froze, which made it difficult for scavengers to eat. Blue Babe is also frequently referenced when talking about scientists eating their own specimens: the research team that was preparing it for permanent display in the University of Alaska Museum removed a portion of the mummy's neck, stewed it, and dined on it to celebrate the accomplishment.
