"One reason we don't have any rats in our Detroit mine is because the
rats would have nothing to eat except the leavings of our lunch pails.
And by the way, not only are there no rats or cockroaches or other
living creature in our mine, but also no remains of living things from
past ages. The salt vein is, of course, a dried up sea that once
covered this section for hundreds of miles. You'd naturally suppose
that some fish or vegetation would have been pickled or fossilized in
the brine as it hardened. But I've never seen a single fossil or sea
shell or any remains of that kind"
environments inhospitable to all but extremophiles. If you look
carefully you can probably find fossil archaea.
OTOH, I wouldn't be surprised to find subfossil flamingos in the soda
lakes of the African Rift Valley. And stuff can be washed or blown in -
look for fossil pollen grains.
So, on the face of it macrofossils can be expected to be relatively
scarce in salt deposits, but present in small numbers.
