KENTUCKY – The fossils of a previously undiscovered ancient shark have been uncovered at Mammoth Cave National Park. The shark, which likely grew to less than a foot in length, is named Macadens olsoni.
Macadens olsoni features a unique tooth whorl, a curved row of teeth meant to crush small sea creatures. It likely feasted on mollusks and worms. The fossils were found in the Ste. Genevieve Formation dating back to approximately 340 to 335 millions years. At that point in time, Mammoth Cave was underneath a warm, shallow sea full of crinoids, corals, and other life.
“This discovery is a remarkable addition to our understanding of ancient marine life and underscores the importance of preserving and studying our natural history.” – Superintendent Barclay Trimble.
The shark was given the name Macadens olsoni to pay tribute to Mammoth Cave and retired scientist Rickard Olson, who played a significant role in the documentation of shark fossils throughout the park. A team of scientists from the National Park Service Paleontology Program, Mammoth Cave National Park, and the Smithsonian Paleobiology Department conducted the research.
“This finding not only enhances our knowledge of ancient marine ecosystems but also emphasizes the critical role of paleontological research in our national parks. Every discovery connects the past with the present and offers invaluable educational opportunities for students and the public.” – Barclay Trimble
