A supernova blast 41,000 years ago started a deadly chain of events that led to the extinction of mammoths and other animals in North America, according to two scientists.
If their supernova theory gains acceptance, it could explain why dozens of species on the continent became extinct 13,000 years ago.

Geez, how did they ever find out his name???
Easily testable...
If the tusks are riddled with craters, there should be some of the causative material embedded in them, one would think.
A Neandertal mitochondrial DNA sequence has been constructed and compared with homo sapien mitochondrial DNA. The comparison supported the idea that they didn't interbreed.
Seems to me that if there were a Supernova blast within 250 LY of earth, even 40K years ago, there would be ample astronomical evidence of such.
I'd like to know if that is the case also. If anyone in the know could weigh in...
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.
I wonder whether the Northern European troll myths are a folk memory of the last Neaderthals. Presumably places like Norway would have been their last holdouts.
Driver's license I would imagine. Mastodons and mammoths are very law-abiding creatures.

Thanks. Just when you think that you've had an original thought it turns out that you haven't...
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)
Looks like Fred Gaystone and Barney "Frank" Rubble. No wonder they're extinct. Sorry - I'm being "intolerant" again.
tusk craters....ooooo-kay
If this theory can be so "easily tested" why does he have to present compelling arguments? I think I know the answer.
