The Ancient Bison (Bison antiquus), also known as the antique or ancient bison, is an extinct species of bison that lived in Late Pleistocene North America until around 10,000 years ago.
Thought to have been extinct for 10,000 years, large herds still roam on Primeval Island. In fact, they are among the most common ungulates there, alongside Megaloceros, Camelops, and the Aurochs. They are the one of largest ungulates on the island as well.
