The Ancient Bison, Bison antiquus, was the most common large herbivore of the North American continent and is a direct ancestor of the living North American bison.

During the Pleistocene Ice Age, Steppe Wisent (Bison priscus), migrated from Siberia into Alaska. They descended to Long-horned Bison (Bison latifrons) and lived in North America for 3 million years. About 22,000 years ago, Long-horned Bison died out and gave way to the Ancient Bison. Ancient Bison were abundant 10,000 to 18,000 years ago then became extinct about 10,000 years ago and is the most commonly recovered herbivore from the La Brea tar pits.

The Ancient Bison was taller, and had larger bones and horns and generally 15-25% larger than modern day bison. From tip to tip, the horns of the Bison antiquus measured approximately 3 feet.
