Avoiding the 'F word' on Mars

"'Fossils are rare in rocks from the era before multicellular life,'" a NASA scientist explained to me privately, agreeing that microorganisms would be very difficult to ever find. 'But larger fossils are fairly common in more recent strata. If Mars ever had macroscopic life, whether truly multicellular or in the form of large colonies like stromatolytes, fossils would be discoverable with a reasonable search.'"
