The fossilized tooth of a newly found historical shark species – courting again about 340 million years – has been unearthed on this planet's largest cave system, officers mentioned.

The shark seemingly measured just below a foot lengthy and preyed on mollusks and worms when Mammoth Cave was a shallow sea wealthy with crinoids, corals and extra, officers mentioned.
“Each discovery connects the previous with the current and provides invaluable academic alternatives for college students and the general public,” Trimble added.
Researchers named the species after Mammoth Cave and Rickard Olson, a retired park scientist.
The most recent discovery marks the fifth “new to science” shark species recognized within the cave system.
