330-Million-Year-Old Shark's Head Fossilized In Kentucky Cave Found By Scientist by Macsjebs(m): 12:44pm On Feb 13
Kentucky's Mammoth Cave National Park is a long way from the ocean, but newly discovered fossils suggest the area was once teeming with sharks.

Scientists have identified the remains of 15 to 20 different species of sharks deep in the cave, including part of the head of a great white-sized monster that's partially protruding from a wall, paleontolo

The sharks lived about 330 million years ago in what is known as the Late Mississippian geologic time period, when much of North America was covered by oceans. When they died, their remains were encased in sediment that eventually became the limestone where the cave formed.

"There's hardly ever any any record at all of sharks teeth coming from these rocks. So that was exciting, Hodnett sad. "So this is a brand new record of sharks from a particular layer of time."

Mammoth Cave scientists Rick Olson and Rick Toomey were mapping a remote part of the cave when they started seeing shark fossils, according to Vincent Santucci, senior paleontologist with the National Park Service.

They sent photos of their find to Hodnett, because he's an expert on Paleozoic sharks. He works at Maryland's Dinosaur Park, a fossil site near Washington, DC, and does support research for the National Park Service.

There were quite a few shark teeth in the photos, Hodnett said, but he also saw cartilage that he thought might be a shark's skeleton. That's pretty rare because cartilage is softer than bone, so it's not often preserved.

When the scientist visited the cave in November, he realized he was looking at something much bigger.

"It turns out is actually not a skeleton, it is actually just parts of the head. And the head itself is pretty big," Hodnett said.

You can see the part of the shark's jaw where it would have attached to the skull and the end that would have been its chin, Hodnett said. Some of the middle of the jaw isn't visible, but he estimated that it would have been about 2 1/2 feet long.

By studying its teeth, Hodnett was able to determine that the fossil was part of a species called Saivodus striatus that was about the size of a modern great white shark -- about 16 to 20 feet long.

He said they don't know how much of the shark is still entombed in the rock.

"It's super exciting, but not exactly the most easy thing to study," Hodnett said. "Caves are a very special environment, so it's not ideal to be removing big chunks of rock out of it and damage the the internal environment by doing this."

Getting to this part of the cave is a challenge of its own. Hodnett said they had to crawl on hands and knees for about a quarter mile to reach their prize.

"It's gonna be very hard to bring the appropriate equipment in there to to properly excavate the specimen out of the cave," he said.
Hodnett said he is still studying the fossil specimens he has collected from the cave, but he's already learned a lot. He estimates that he's found the fossils of about 150 different sharks from 15 to 20 different species.

Most of the fossil record from the Late Mississippian period was found in Europe, so this could answer a lot of questions about what was going on then in North America.

"We literally just scratched the surface, and the sharks are just coming out from that scratch," Hodnett said. "So, hopefully, with more field work, we'll get another good batch of specimens to kind of help get at least some more rich diversity."

The researchers plan to present their preliminary findings in October at a meeting of the Society of Vertebrate Paleontology.
Santucci said the fossils were found in a remote part of the park that people can't visit without special permission, but they don't want to reveal the exact location.

Eventually, he said, they'll display the fossils in the park and online. But, he says, the project is just getting started.

"It's amazing how quickly we've already found some interesting stuff," Santucci said.

Ok

Na like this FTC be? Rogers network did well today.

This is dedicated to all honest Nigerians who are doing legitimate jobs to survive. May almighty God bless your hustle. And to all of you whose source of income bring anguish to others, may you meet your waterloo soon.

And to all those Nigerian university professors and researchers using research grants to flex, you will soon be fished out.

God bless Nigeria.

The dude up there is a genius.. He is probably not using glo network like me.
Oyinbo self dey confused. How come they keep coming up with different dates after discovering some fossils buried somewhere? Is there any precise instrument for measuring the age of these discoveries or its just mere estimation?

Naija Wetin concern us with fossil when the whole country is in total confusion? .. Yesterday, slim shaddy was booed in Borno State and boko boys attacked the same area the second time.

Abeg make una help me tell that overhyped Fela wannabe that a drum that sounds louder is about to burst.

Interesting...

Back in the Carboniferous period.

Sharks (especially the Stethacanthids) underwent a major evolutionary radiation during the Carboniferous. It is believed that this evolutionary radiation occurred because the decline of the placoderms at the end of the Devonian period caused many environmental niches to become unoccupied and allowed new organisms to evolve and fill these niches. As a result of the evolutionary radiation Carboniferous sharks assumed a wide variety of bizarre shapes including Stethacanthus which possessed a flat brush-like dorsal fin with a patch of denticles on its top. Stethacanthus's unusual fin may have been used in mating rituals.

If that record is true, that must be the time of the great flood.
But Back in Nigeria they is no such of records above 200 yeres, dose is mean that our ancestors eat everything as we do today?
