340-Million-Year-Old Shark Tooth Found In World's Largest Cave
A fossilised tooth from a previously unknown ancient shark species, estimated to be around 340 million years old, has been discovered in Kentucky's Mammoth Cave National Park, the world's largest cave system. The species, now named Macadens olsoni, was found in the Ste. Genevieve Formation, which dates back to the late Mississippian period. The tooth, about half an inch long, offers valuable insights into prehistoric marine life. The National Park Service announced the discovery shortly after the start of 'Shark Week,' adding to public interest in ancient sharks. "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 in a news release. Macadens olsoni is notable for its unique tooth whorl, a curved row of teeth designed for crushing small sea creatures. This ancient shark likely grew to less than a foot in length and probably feasted on mollusks and worms. The fossils of Macadens olsoni were found in the Ste. Genevieve Formation, which dates back approximately 340 to 335 million years. During that time, Mammoth Cave was submerged in a warm, shallow sea teeming with life including crinoids and corals. The name Macadens olsoni 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 (PRI). The research was conducted by a team of scientists from the National Park Service Paleontology Program, Mammoth Cave National Park, and the Smithsonian Paleobiology Department. In addition to Macadens olsoni, researchers studied another ancient shark, Helodus coxanus, now renamed Rotuladens, meaning "Wheel Tooth." This species shares similarities with Macadens olsoni and highlights the diversity of ancient marine life. "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."

Ancient new shark species — dating back 340 million years — unearthed in world's largest cave system
A rare bite into the past. The fossilized tooth of a newly discovered ancient shark species – dating back about 340 million years – has been unearthed in the world's largest cave system, officials said. The roughly half-inch tooth from the uncovered species, named the Macadens olsoni, was found in the depths of Ste. Genevieve Formation at Mammoth Cave National Park in Kentucky, the National Park Service announced Thursday, just four days after 'Shark Week' officially kicked off. Advertisement The Ste.

Paleontology researchers, who discovered the marine fossil, said the ancient predator is notable for its distinctive tooth whorl — a curved row of teeth that crushed small sea creatures. The shark likely measured just under a foot long and preyed on mollusks and worms when Mammoth Cave was a shallow sea rich with crinoids, corals and more, officials said.

Ancient shark species — with teeth made for ‘crushing' — found in Kentucky cave
About 340 million years ago, a tiny shark swam in the waters of the world's longest cave system in Kentucky, its unusual mouth curved in a way that will ultimately end up defining its future legacy. Now long gone, a team of scientists have stumbled upon its fossils in Mammoth Cave, Kentucky, a July 24 news release from the National Park Service said. The new species of ancient shark was named Macadens olsoni, which means 'Olson's Mammoth Cave Tooth,' and it has a very distinct feature. 'Macadens olsoni is notable for its unique tooth whorl, a curved row of teeth designed for crushing small sea creatures. This ancient shark likely grew to less than a foot in length and probably feasted on mollusks and worms,' rangers said in the release. The name was chosen to honor the fossil's resting place and Rickard Olson, the scientist whose work was essential to Mammoth Cave. 'This discovery is a remarkable addition to our understanding of ancient marine life and underscores the importance of preserving and studying our natural history,' Mammoth Cave National Park Superintendent Barclay Trimble said in the release. According to the National Park Service, more than 40 different species of ancient sharks have been discovered in the past 10 months in Mammoth Cave. 'Most of the shark fossils have been discovered in areas inaccessible to visitors on cave tours, but photographs, artists' renditions, and three-dimensional models are being prepared for the visitors to view and explore in park exhibits and websites,' NPS said. Other major finds in the cave include the Tolleson's Scraper Tooth (Strigilodus tollesonae,) an ancient shark with 'spoon-like teeth' and the Chipmunk Shark (Clavusodens mcginnisi). '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 said of the newest find . 'Every discovery connects the past with the present and offers invaluable educational opportunities for students and the public.' Mammoth Cave is about a 95-mile drive south from Louisville.

Green River Ferry at Kentucky's Mammoth Cave National Park damaged during historic flooding
MAMMOTH CAVE, Ky. – Parts of Kentucky have recently suffered historic flooding, causing some damage at Mammoth Cave National Park. Among the impacts from the severe storms, the Green River ferry infrastructure at the national park sustained heavy damage to its navigational cables and support towers, according to a press release from the National Park Service. As a result, all ferry operations will be closed for several months until repairs are complete. "Our team is assessing the damage at the Green River Ferry to determine if we can simply make repairs to the existing cables and towers or if a full reconstruction of the system is required," said park Superintendent Barclay Trimble. "The ferry is an important link for our visitors, staff, and local communities to cross the Green River, but, unfortunately, the damage we are seeing from the flood is not easily fixed." Park officials say the Green River ferry operates using cables and four 20-foot tall towers. The navigational cables used to guide the ferry across the river are approximately 15.5-ton concrete anchors placed deep in the riverbank. The Green River Ferry was built in 1934, according to the NPS, and is the last remaining active ferry in the park. It runs 364 days a year and transports vehicles, hikers, and bikers. The water levels at the Green River ferry crossing average between 15 and 22 feet during April, with a flow just below 5,000 cubic feet per second. Renewed Severe Storms Target Midwest, South Threatening Easter Travel For Millions This Weekend During the recent historic flooding, officials say the river reached a crest of 59.54 feet and a water flow of just over 55,000 cubic feet per second. Park officials state that the heavy flooding pulled concrete anchors and moved them 20 feet downhill. The ferry won't be able to operate until the cable system and towers are repaired. Although the vehicle ferry operation and boat ramp are closed, the Green River Ferry day area will remain open for visitors. The Green River Ferry Road North will stay open to passenger vehicles article source: Green River Ferry at Kentucky's Mammoth Cave National Park damaged during historic flooding
