Mammoth Cave in Kentucky stretches for more than 420 miles (675 kilometers) below the surface of the ground and is often described as the world’s largest cave system. Recent explorations there uncovered two new fossil sharks that once roamed shallow coastal waters more than 325 million years ago.

Ancient shark specialist John-Paul (JP) Hodnett of the Maryland-National Capital Parks and Planning Commission (MNCPPC) worked with the National Park Service Paleontology Program to identify the fossils.
