Comet may have exploded over planet, causing fires, die-offs, researchers say
A meteorite colliding with the Earth 65 million years ago is considered to be the most likely reason dinosaurs vanished from the planet. Now a team of scientists says it has found new evidence that an object from space caused a similar extinction event only 13,000 years ago.
In an article to be published Friday in the journal Science, researchers present what one author calls the "smoking bullet"proof that an exploding comet triggered the sudden, thousand-year freeze that killed off mammoths, saber-toothed tigers and other large mammals that used to live in North America.
Working at multiple sites across the continent, researchers found nanodiamondsmicroscopic particles thought to be found on cometsin a 13,000-year-old layer of carbon-rich soil.
The authors, led by University of Oregon anthropologist Douglas Kennett, theorize that the comet exploded above the Earth's surface, raining fragments upon North America and starting fires across the continent. That would have ushered in an abrupt global cooling and caused the "megafauna" extinction.
In the layer with the nanodiamonds, fossils of the large mammals are abundant. After that layer, they disappear, said Allen West, an Arizona geophysicist and one of the paper's authors.
"It's extraordinary that tens of millions of animals disappeared synchronously at exactly the time when the diamonds and carbon layer are laid down across the continent," West said.
West said the event also would have affected human populations of the time. Artifacts from the Clovis culture of humansan early hunter-gatherer societyalso disappear after the 13,000-year layer, suggesting they, too, were killed off by the comet or its aftereffects.
Many archeologists remain skeptical of the comet theory, said Daniel Amick, an associate professor of anthropology at Loyola University Chicago who studies the Clovis culture.
"When most archeologists heard...,"

We can't go that far... It could have been some bad ju-ju ceremonies of your ancestors that attracted the comet in the first place!
It's happened on this planet and it's clearly happened on other planets in the last 20 years - don't know why we don't think it could happen here in the foreseeable future.
Don't count on it. We will see many articles or discussions with sentences like, "..., the problem that 0bama inherited from Bush's administration,..." or, "... the problem is not new. It is the result of the previous administration's policies...". I suspect at least we'll see those the next four or (God forbid) eight years.
According to the Mayan/Olmec/Aztec calendar (the same calendar adopted by the Aztecs), the last great period of destruction occurred 13,000 years ago, when the Earth was rattled by Earthquakes,volcanic eruptions, and terrible floods: events they blamed on a cosmic calamity, and which they, and other ancient peoples, associated with the Great Serpent, which was associated with Venus.

And within the prophecies there is mention of a great “recharging light” to our sun.
All just totally coincidental this evening. I just happened to be delving into some of the Mayan Calender stuff and the turning of the new age. The figure 13,000 years ago stuck out like a sore thumb as it is recorded in the Mayan calender. Lots of things seem to correlate including our crossing the axis of the galaxy, even the last thought pole reversal happens in that timeframe.
I know, the RATS and MSM will be blaming Bush for everything that happens for Obama’s entire term, but after Bush leaves office, it won’t matter, it will just be transparent excuse-making.

There were also linguistic studies in North America that suggested that NorthAm languages were a subset of South American languages, due to greater language diversity in the South American continent.
Yet North America was settled first.
This scenario gives another answer. There were lots of people in North America, but many of the North Americans (and their languages) were wiped out 13000 years ago. The surviving South American populations were thus larger as well as over a greater area, allowing their linguistic diversity to continue to increase.
This may also explain why the oldest mitrochondrial DNA on the continent is the Pacific Northwest. Lots of mountains to protect you from the asteroid strike, and ocean food sources that make the land extinctions less likely to make the people extinct.

I note how this possible event has been linked to the Carolina Bays.
Some of those Bays are lakes. Has anyone ever done any core sample drillings of the lake bottoms?
Should be a simple matter to figure out almost EXACTLY how old they are.
