During the [[Pleistocene|Pleistocene Ice Age]], [[Steppe Wisent|steppe wisent]] (''Bison priscus''), migrated from [[Siberia]] into [[Alaska]]. This species then developed into the [[Bison latifrons|long-horned bison]] (''Bison latifrons'') which lived in North America for 3 million years. About 22,000 years ago, the long-horned bison gave way{{clarifyme|Date=November 2007}}<!-- Did it evolve into the ancient bison or what? --> to the ''Bison antiquus''. ''B. antiquus'' were abundant from 18,000 years ago until about 10,000 years ago, when they became extinct, along with most of the [[Pleistocene megafauna]]. ''B. antiquus'' is the most commonly recovered herbivore from the [[La Brea tar pits]]. ''B. antiquus'' was taller, had larger bones and horns and was 15-25% larger overall than modern bison. From tip to tip, the horns of ''B. antiquus'' measured approximately 3 feet (nearly one meter).
