Photos: US Scientists Stumble Upon Fossilized Head of 330 Million-Year-Old Shark

Mammoth Cave National Park has quickly become a site of interest for scientists, as an ongoing project has resulted in the discovery of fossilized remains belonging to a 330 million-year-old shark and dozens of other specimens.

Rick Olson and Rick Toomey, two experts of central Kentucky’s Mammoth Cave tasked with mapping the structure, contacted Vitor Santucci, the senior paleontologist for the US National Park Service, after stumbling upon a fossilized figure that jutted out of the wall, according to the Louisville Courier Journal.

Santucci then got in touch with colleague John-Paul Hodnett of Maryland’s Dinosaur Park, who paid a visit to the cave in November 2019 as part of the Mammoth Cave National Park Fossil Shark Research Project.

“One set of photos showed a number of shark teeth associated with large sections of fossilized cartilage, suggesting there might be a shark skeleton preserved in the cave,” he said, recounting the initial photos taken by Olson and Toomey.

“I wasn’t exactly sure what I was going to see in the cave during my trip in November,” the paleontologist confessed. “When we got to our target specimen, my mind was blown.”

According to Hodnett, members of the project determined that they had found what appear to be several teeth belong to the shark, its lower jaw and skull cartilage. The latter finding is most monumental due to the fact that shark skeletons – which are made of cartilage – are rarely preserved in fossils.

“Most significantly, the majority of the shark fossils we discovered come from a layer of rock that extends from Missouri to Virginia but never documented the presence of sharks, until now,” Hodnett said. “It’s like finding a missing puzzle piece to a very big picture.”

Santucci told the Courier Journal that although the park wants the public to benefit from the information obtained from the cave, officials “have a duty to protect these non-renewable resources” and will not disclose the fossils’ exact locations out of fear of vandalism or theft.
