In a major find, the fossilized remains of a new species of shark were discovered in the Ste. Genevieve Formation in Kentucky, the Mammoth Cave National Park confirmed in July.
Named the Macadens olsoni, the new shark species now joins the list of paleontological discoveries at the site. The species’ name pays tribute to both Mammoth Cave and Rickard Olson, a retired park scientist who played a crucial role in documenting shark fossils in the park as part of a recent Paleontological Resource Inventory.
“This discovery is a remarkable addition to our understanding of ancient marine life and underscores the importance of preserving and studying our natural history,” said Superintendent Barclay Trimble.
Macadens olsoni is notable for its unique tooth whorl, a curved row of teeth designed for crushing small sea creatures.
About the Macadens olsoni
The ancient predator would have grown to less than a foot in length and likely feasted on mollusks and worms. The Ste. Genevieve Formation, which dates back approximately 340 to 335 million years, along with the rest of the park, was once a warm, shallow sea with a vibrant variety of inhabitants.
“This finding not only enhances our knowledge of ancient marine ecosystems but also emphasizes the critical role of paleontological research in our national parks,” Trimble added.
“Every discovery connects the past with the present and offers invaluable educational opportunities for students and the public.”
