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.
