A previously unknown species of ancient shark has been discovered in Kentucky's Mammoth Cave National Park, home to the world's longest cave system.The system, which is located in the state's south-central region, extends for more than 400 miles and features a series of large underground passages. The system's rocks date to the Mississippian period , around the time that the supercontinent Pangea was forming.

The creature is a kind of petalodont , an extinct group of cartilaginous marine fish found in what is now the United States and Europe.'We are excited to finally announce the discovery of our first new shark species at Mammoth Cave on National Fossil Day,' Barclay Trimble, the park's superintendent, said in a press release.
