What's Happening?
A new species of ancient shark, named Macadens olsoni, has been discovered at Mammoth Cave National Park in Kentucky. The fossils, found in the Ste. Genevieve Formation, date back approximately 340 to 335 million years. This discovery was made by a team of scientists from the National Park Service Paleontology Program, Mammoth Cave National Park, and the Smithsonian Paleobiology Department. The shark, which grew to less than a foot in length, likely feasted on mollusks and worms. It is notable for its unique curved row of teeth designed for crushing small sea creatures. The name Macadens olsoni honors Rickard Olson, a retired park scientist who contributed significantly to documenting shark fossils in the park.

Why It's Important?
The discovery of Macadens olsoni enhances the understanding of ancient marine ecosystems and underscores the importance of paleontological research in national parks. Such findings provide invaluable educational opportunities for students and the public, connecting the past with the present. The research highlights the diversity of ancient marine life, with more than 40 different species of fossil sharks and relatives identified from Mammoth Cave specimens in the past 10 months. This contributes to the broader scientific knowledge of marine biodiversity and evolutionary history.
