The Mars meteorites have been classified into 4 groups (or 5 groups, depending
who you talk to), and their ages vary, so it is clear that the Mars
meteorites do not come from a single impact.  This is just another piece
to the puzzle that Zagami and Chassigny did not come from the same meteor
stream.
