Probably the best condition for fossil creation/preservation would be aqueous catastrophism(ie... flood), stratum deposited in rapid succession. Quick coverage of plant or life form would/do present terrific fossils.
The answer of 'Quick freezing' is not so likely. I can't think of anywhere there would suddenly be 'flash freezing' upon our planet. Life forms would have a chance to move away from such conditions of cold and plants would die out. Although death within a cold temperature area would lend to good preservation of a life form.
"Quick Freezing"
