Evidence of extinction event could be at the bottom of a South Carolina pond
Researchers say they’ve discovered proof that an asteroid or comet exploded over Kershaw County hundreds of years in the past, inflicting big adjustments to life in that space.
ELGIN, S.C. — Quite a lot of consideration has been generated within the South Carolina city of Elgin following the earthquakes there in current months. However Elgin can be making headlines for a shocking discovery made by a former College of South Carolina archaeologist, Christopher Moore, and his staff of researchers.
Moore and his staff of researchers consider they’ve discovered indicators supporting an extinction concept referred to as the Youthful-Dryas Affect Speculation. They usually’ve discovered proof that seems to reveals an asteroid or comet exploded over Kershaw County hundreds of years in the past, inflicting big adjustments to life in that space..
“I wished to come back to White Pond as a result of I knew the mud and the sediments within the pond had a document of local weather during the last not less than 20 or 30,000 years,” Moore defined.
The Youthful-Dryas Affect Speculation states an asteroid or comet hit the Earth almost 13,000 years in the past, splintering into smaller elements over the skies of a number of continents. The outcome led to a decline in animal and human populations. Proof in help of the proposition, Moore mentioned, was discovered on the backside of White Pond in Elgin in recent times.
“Properly while you dig down in sure areas you’re going again in time,” Moore mentioned. “So that you begin on the floor and you’ve got the newest time durations, and as you go down, it’s like a time capsule, and also you’re going additional again in time.”
Groups excavated in three or 4 toes lengthy block units–individual segments the place the Earth is peeled back–across elements of the White Pond space. Moore mentioned on the deepest a part of the block they’ve discovered artifacts which might be 12,000 years previous.

Moore mentioned proof discovered within the pond’s sediment suggests an asteroid or comet exploded within the skies over South Carolina all these years in the past. If that’s the case, the occasion would have brought on huge wildfires, creating sufficient smoke to dam out the solar for a number of weeks or months. And it might have been sufficient to contribute to the extinction of a number of giant animals that roamed the Earth.
“It’s doable that we had mastodons,” Moore mentioned. “We could have had herds of mastodons coming right here to drink. We might have had herds of bison. That’s actually primarily based on another work that I’ve carried out. It’s recommended that we most likely had herds of bison, elk, different giant animals.”
“The fossil document for that point in South Carolina can be not superb however we all know in the event you go additional again in time there’s all types of proof of mammoth, mastodon, large floor sloth, sabertooth cats, you title it,” he added. “Very giant animals that each one went extinct.”
In 2019, Moore and his colleagues first revealed their findings in Scientific Reviews, a publication of Nature.
Researchers have been additionally in search of proof of the Clovis tradition. The Clovis have been thought of to be the earliest Native Individuals and artifacts of the Clovis individuals have been discovered all through the US.

“These individuals have been right here…and made this very distinctive stone know-how after which they appeared to very quickly change or shift,” he mentioned. “I’m not saying they go away however they transition across the starting of the Youthful-Dryas, about 12,800 years in the past.”
And whereas no proof of the Clovis individuals has been at White Pond, Chris mentioned they are going to broaden their search within the coming months, hoping to seek out extra proof to help their concept.
“it’s a extremely debated matter,” Moore admits. “And I believe the opinions of archeologists and geologists range. It’s just like the dinosaur extinction asteroid occasion when that proof was first offered. It was extremely controversial and it took a whole lot of time and work earlier than it was broadly accepted.”
“This isn’t broadly accepted essentially however there’s loads of proof to help an occasion occurring.”
And because it occurred as soon as, might it occur once more?
“You realize you hear reviews on a regular basis of asteroids that come between us, the Earth, and the moon, and most of these are pretty small and wouldn’t essentially do a whole lot of harm however there are some on the market which might be giant sufficient to do important harm in the event that they have been to hit the earth. And it’s only a matter of time earlier than that occurs.”
