Macadens olsoni had a distinctive curved row of teeth known as a crown denticle.
Scientists have found the remains of this ancient shark deep within the world's longest cave system.
A newly discovered shark, pulled from the walls of Mammoth Cave in Kentucky, lived approximately 340 million years ago and had curved teeth that it used to grind up its food.
According to information posted by the National Park Service (NPS), Macadens olsoni was a small shark, less than 1 foot (30 centimeters) long, and most likely fed on shellfish and worms.
