Prehistoric Shark Tooth Discovered in Mammoth Cave National Park Helps Scientists Understand Ancient Marine Ecosystems
A fossilized shark tooth about 340 million years old was found in the largest cave network in the world. The discovery was made in the Ste. Genevieve Formation, within Mammoth Cave National Park in the state of Kentucky, United States.
The fossil measures approximately 1.3 centimeters and belongs to a new species of shark named Macadens olsoni.
The information was released by the National Park Service last Thursday, the 24th, just four days after the start of the traditional “Shark Week.”

The Ste. Genevieve Formation is a geological site dated between 335 and 340 million years. During this period, the area that now houses the park was a shallow marine environment teeming with life such as crinoids, corals, and other organisms.
The park superintendent, Barclay Trimble, commented that the discovery is an important contribution to knowledge about ancient marine life.
According to him, the fossil “highlights the importance of preserving and studying our natural history.” The statement was echoed by the NY Post this weekend.
Trimble also stated that the finding “enriches our understanding of primitive marine ecosystems” and reinforces the essential role of paleontological research in the national parks of the United States.
According to the researchers involved, the shark Macadens olsoni stands out for its dentition with rows of curved teeth.
These teeth were suitable for crushing small living beings, such as mollusks and worms. The estimate is that the animal was about one foot long, approximately 30 centimeters.
The new species was named in honor of Mammoth Cave and retired scientist Rickard Olson.
The recognition is a way to value Olson’s contributions to scientific studies within the park.
“Each new discovery connects the past to the present and provides invaluable educational opportunities for students and the general public,” concluded Trimble.
