I respond as a logician with interests in biology. The problem here is
the assumption that _all_ deposits will be disrupted, the fallacy of
false generalization. I can immediately think of two kind of deposits
that will not be. First, there are anoxic areas where marine life, except
for some bacteria, cannot live. Second, there are benthic areas where
there is little life, and what there is seems to be on the surface rather
than burrowing. I expect that those knowledgeable in the area of marine
sedimentation can provide additional examples.
