Hi Richard, all -

At least here on the meteorite list the peanut gallery is allowed to squeak.

Amazing - There appear to be no mention of either Chicxulub or Shiva in the wikipedia article on extinctions:

http://en.wikipedia.org/wiki/Extinction

Apparently, they're all due to global warming now.

When one of the larger YD craters is definitively proved, then obviously it will have to be co-incidental to the extinction that occurred then. And/Or it will have to be a Carbonaceous asteroid that hit. And of course the First Peoples detailed memories of those comet fragment impacts are simply fairy tales made up by retarded savages.

My mistake! :p)

Now since the Nemesis Hypothesis has been thoroughly disproved, perhaps you'll send Morrison a note suggesting that he update this piece:

in which he thoroughly endorsed the Nemesis Hypothesis as the standard paradigm, while damning Clube and Napier.

Aside from that, I am thoroughly enjoying the images of the fragments of 73P which are being posted to the MPML. I hope that some IR images of 73P's dust load come along shortly.

good hunting,

PS - I tried to get some YD nanodiamonds from an excavator to sell to list participants, but he thought the commercialism would sully the science, and the preparation costs were too high.
