well, time to change those science books AGAIN as another theory falls on its face. apparently. maybe. for a while.
How long before it's blamed on President Bush?
I'm waiting. I'm still waiting. Still waiting. Still.....
Author doesn't know what she's talking about.....Michael Moore is still around.
The 6,214 miles-per-second iron-rich grains would have riddled everything like bullets.
Seems the much more likely explanation is the arrival of man at about the same time. The same thing happened to many large mammal species in Australia after mankind arrived on that continent.
Any Astronomers here?
Is there any evidence of a Supernova within say, 500 LY of earth within, say, the last 100K years?
Any evidence at all?
Concerning the presently existing astronomical evidence of supernova blasts that have been recorded, how old are they? ( regardless of distance )
How old is the presently seen evidence of those explosions?
Is it fairly easy to recognize the post-supernova evidence?
I don't recall hearing/reading of any nearby (relatively) evidence of large clouds of ionized particles, x-ray emmissions from massively accelerated solar mass, etc....
Seems to me if you're going to claim "supernova killed the mammoths", pitted craters in mammoth tusks is not primary evidence to validate your claim..
The primary evidence is the remains of a supernova..
Where is it???
My previous posts were written before reading the article.
Bad habit.
But seriously, folks, this is a truly idiotic article. To believe it, you must believe that a supernova 250 light years from Earth affected North America, and only NA, in at least two separate events tens of thousands of years apart.
It seems to me that mammoth tusks riddled with iron-rich particles would be more likely to be related to a localized event, perhaps a volcanic eruption, than to an astronomical event that mysteriously affects all of NA but not the rest of the planet.
You must also believe that saber-toothed cats were less able to take shelter in a cave or elsewhere than elk or moose or (regular-size) bison!
It is possible that the actual science makes more sense than this idiot article.
That was interesting, Thanks.
Easily testable...
If the tusks are riddled with craters, there should be some of the causative material embedded in them, one would think.
The inlay is made from Mastadon tusk. I did a search for mammoth tusk and found that there is a lot on the market via Ebay, primarily from Siberian origin and sells as carved figurines.
I think fad dieting killed them.
React to that FEMA!

This sounds a lot like Velikovsy's "Worlds In Collision". There was a freeze 13,000ya that probably had great bearing on the extinction but pairing it with a 40,000ya event is a pretty tough case to make.
This image provided by NASA's Hubble Heritage team Tuesday Oct. 4, 2005 shows a supernova remnant, the ejected material from the explosion of a massive star, that occurred some 3,000 years ago. This titanic explosion took place in the Large Magellanic Cloud, a nearby neighbor galaxy some 160,000 light-years away. This composite image of N132D comprises visible-light data taken in January 2004 with Hubble's Advanced Camera for Surveys, and X-ray images obtained in July 2000 by Chandra's Advanced CCD Imaging Spectrometer. The complex structure of N132D is due to the expanding supersonic shock wave from the explosion impacting the interstellar gas of the LMC. A supernova remnant like N132D provides information on stellar evolution and the creation of chemical elements such as oxygen through nuclear reactions in their cores. (AP Photo/NASA)
