Really, can you imagine making an announcement like that and typo such
important dating?

Your question is really a good one, and I have always thought that there
MUST be some terrestrial 'meteorites' misclassified as being of
extraterrestrial origin.
I also would like to hear a good reason why they are missing from the
find records.

CharlyV

 "SNC meteorites are extremely rare - fewer than 20 confirmed
examples have been discovered - and are believed to all come from the
same body of rock. They are distinguished by their relative youth, being
at most 1.3 million years old, compared to 4.5 million for other
meteorites." From "Scientists find Mars meteorite" "From Gerard Sevestre
in Paris" January 04, 2004.
 Hum, 1.3 million, 4.5 million? Not 1.3 billion and 4.5 billion?
"fewer than 20 confirmed examples"???
Regards, Fred Hall
 What was Earth's atmosphere like 1.3 Billion years ago? I'm sure
Earth had hydrated basaltic rocks then, right? Is there any possibility
that some of the SNC's (lava meteorites) are not from Mars, but Earth?
Isn't there an Earth meteor crater that formed around 1.3 billion years
ago? I have yet to hear a good reason as to why we have not found an
"Earth meteorite". Some scientist out there, please set me straight as
to why we have found some 25+ Mars meteorites and not one Earth
meteorite.
Thanks
