This 1.25-inch fossilized horn coral from Cave-in-Rock, Illinois is over 340 million years old, dating back to the Mississippian Period. The natural coral cavity is lined with sparkling quartz or calcite crystals, giving it the appearance of a tiny geode fossil — a beautiful blend of geology and paleontology.
Each fossil from this area formed when ancient coral reefs were replaced and filled by minerals, preserving incredible detail and creating a shimmering natural display.
