American Bison Fossil Leg Bone

This fossilized leg bone comes from an extinct American bison (Bison sp.), a large herbivorous mammal that roamed North America during the late Ice Age. Bison played a critical role in prehistoric ecosystems, shaping grasslands through grazing and migration.

The bone preserves clear anatomical features of the lower limb, reflecting the strength and weight-bearing structure needed to support a massive animal adapted for long-distance movement across open plains.
