It looks like there were some unauthourized changes to the original article,

Hi Ron and all,

Thanks for the story.

Two lines make me wonder exactly what meteorites they used in the research:

> System was made up of fine dust and gas.

and

existence

I ran a query for carbonaceous meteorites using the COM database and
came up with 36 witnessed falls, and 561 total. Winonites, a total of
11 listed. Brachinites, 7 entries.

Any more info or guesses?

Cheers,

Martin
