This is a horn coral fossil collected from the Mississippian-aged Burlington Formation in Lee County, Iowa. It has been exposed from the matrix it was found in. It comes with an acrylic display stand.
Horn coral, or Rugose coral, first appeared in the geological record 488 million years ago and went extinct during the great Permian extinction 251 million years ago. They get their name from the hornlike structures built by the coral animal. They are very often used as an index fossil to help correlate the geological ages of different formations.
