1.25" Oreodont Fossil Jaw

This specimen is a single jaw fragment from Merycoidodon culbertsoni, a species of oreodont found in enormous herds across North America for over 30 million years.

Oreodonts were short mammals with heavy bodies, long tails, and hoof-like toes. Their name means “mountain teeth” and the sharp ridges of their molars were ideal for grinding the diverse foliage of grassy prairies as well as roots and shoots in wooded areas.
