This fossil addition was found in a Yukon gold mine. Not gold, but the skull and horns of an extinct Ice Age bison, Bison antiquus. It is one of two skulls found in the mine.
From horn tip to horn tip is 8' 4". It probably stood seven feet tall at the shoulder when it lived about 13,000 years ago in Alaska. They were larger than today's plains bison and may have evolved into today's bison as the climate changed out of the Ice Age. Males were larger than females and we believe this skull is male.
It was donated to the Museum by Stanley Davis of Vacaville.
