It should be mentioned that very, very few bacteria sporulate. *Bacillus*, *Clostridium*, and not much else. AFAIK magnetotactic bacteria don't sporulate.
Anyway, I guess the meteorite was settled by bacteria after it had arrived in Antarctica...

The closest known Earth analog to the possible Martian meteorite bacteria is a critter known as bacterial strain MV-1. Magnetite produced by MV-1 resembles magnetite in *some* of those "fossil" blobs found in the Allan Hills Martian meteorite (both in size and shape).
