[Rockhounds] Another extinction impact-13 KYA

[Dora Smith]

The article itself is available at 
http://www.sciencemag.org/cgi/content/abstract/sci;323/5910/94 - for a fee. 
I'm not paying it.

Teh abstract is there, adn also the locations of the study's authors.   It 
looks as if the geologist is a paid consultant.   The abstract mentions two 
kinds of diamond particles found, and I think the terminology is a little 
more technical than six-sided diamonds.

I never heard of hexagonal diamonds, isn't that graphite's crystal
structure?
