337-Million-Year-Old Shark Fossils Found at Mammoth Cave National Park

The ancient waters, which carved the caves, exposed fossils embedded in ancient rock. During work for a paleontological survey, which commenced in 2019, researchers discovered a collection of incredible prehistoric shark fauna sticking out of the cave walls.
