Hyracodon nebrascensis was a sheep sized mammal which reached a length of about five feet with long legs for running. Its horse-like appearance gave it the name "running rhino." It was a browser that likely roamed in small herds in the plains and open forests. It lived during the Oligocene (32-30 million years ago).
Because of replacement minerals, many of the fossil mammal teeth from the White River Formation of South Dakota will fluoresce. Be sure to check them out in our fluorescent section under the South Dakota page and then by the appropriate page for the species you are interested in. The item number will be the same as the item number in this section, but will be followed by an "F."
This specimen is a worn enamel portion of a tooth (no root). The specimen is from the White River, Brule Formation.
