Wow, Venn diagram snobs.

(Although I agree Indexed was much better before it sold out to Staples.)

SEXYROBOT: Mycobacterium tuberculosis doesn't form endospores, and a coal fire would be pretty hard on even those ridiculously hardy species that do.

Endospores can apparently last indefinitely.
Viable bacterial endospores have been recovered and from pockets in 250 Million year-old salt crystals.

When things got salty, the bacteria dried up their DNA etc. and waited 250 MILLION years until someone plucked them out and woke them up in a nice warm petri dish.
