[meteorite-list] Boost to asteroid wipe-out theory & question

[kenoneill at kenoneill.com]

Hi list,


"The idea that an asteroid impact caused Earth's worst ever mass extinction
has been boosted by the discovery of a huge crater that seems to date to the
event. "

If earth rocks were hurled into space by such an event, no doubt they would
end up on other planetary bodies as meteorites. Chances are some of this
material would eventually come back to earth as a meteorite(s). Are there
any meteorites out there where the origin can be shown to have been earth ?



Regards

Ken O'Neill
