Extinct Long-horned Bison & Ancient Bison (Bison latifrons and B. antiquus) Fact Sheet: Diet & Feeding

Extinct Long-horned Bison & Ancient Bison (Bison latifrons and B. antiquus)

How Do We Know This?

Clues to fossil mammals' diets come from not only teeth, but also
skull shape, amount of space indicated by bones for a stomach and guts, from fossil dung and gut
contents, from lab analysis of oxygen isotopes in bone and teeth, and by looking at diets of
similar modern animals.

Diet & Feeding

  • Bison are ruminants that graze and browse
    Bison latifrons: more of a browser than a grazer
    • An eye-level browser, feeding on small trees and shrubs
  • Bison antiquus: more of a grazer; some browsing
    • Feeding on low-growing herbs and shrubs
