Prehistoric horses and bison shared diet

[Still Waters]

University of Cincinnati researchers studied the teeth of prehistoric horses and bison in the Arctic to learn more about their diets compared to modern species.

What they found suggests the Arctic 40,000 years ago maintained a broader diversity of plants that, in turn, supported both more—and more diverse—big animals.

Researchers studied two of the most common big animals living between 12,000 and 40,000 years ago in what is now Alaska: horses and steppe bison, both of which went extinct due to climate change, human hunting or a combination of both.
