Did a Giant Comet Kill the Mammoths?

1 Apr 10 — “Some 13,000 years ago the Earth was struck by thousands of Tunguska-sized cometary fragments over the course of an hour, leading to a dramatic cooling,” says this article on Science Daily.


Though the earth had been warming since the end of the last ice age, this sudden cooling – by as much as 8°C – drove the glaciers forward again.

The cooling lasted more than a thousand years, and its onset coincided with the rapid extinction of 35 genera of large North American mammals, as well as the disappearance of the Clovis culture.

The occurrence is marked by a black mat a few centimeters thick found at many sites across the United States.

The article doesn’t mention it, but in some areas the black mat is a foot thick.

The black mat contains high levels of soot as well as microscopic diamonds, called nanodiamonds. Nanodiamonds are produced by shocks and are (supposedly) found only in meteorites or impact craters.

The catastrophe was caused by an extraordinary extraterrestrial event, says astronomer Professor Bill Napier of the Cardiff University Astrobiology Centre.

Professor Napier proposes that the Earth ran into a dense swarm of material from a large disintegrating comet.

According to Napier, the encounter would have lasted about an hour, during which thousands of impacts took place.

Each impact released the energy of a megaton-class nuclear bomb and generated the extensive wildfires, says Napier. The nanodiamonds would have come in on the comet.

I don’t buy it.

If you’ve read “Magnetic Reversals and Evolutionary Leaps,” you know that I talk extensively of this event, including the black mat and the nanodiamonds. I also point out that radioactivity levels in13,000-year-old soil measure 2,000 times higher than normal. (That could trigger a few mutations and evolutionary leaps, don’t you think?)

I also discuss the Carolina bays – more than two million huge holes in the ground ranging from one acre to thousands of acres – that were gouged into our planet at the same time.

But should we blame a comet?

No. I blame the Gothenburg magnetic reversal, which triggered millions of massive explosions in the sky.

Unfortunately, I think another magnetic reversal is due any day.
