Allen, you are not answering the question. You are speculating. Yes,
it _could_ be a tsunami (given no other information), but UNIFOMITARINAN
processes which also accommodate tsunamis OVER A LONG PERIOD OF TIME, would
be required. Your answer does not address the numbers.

This is rather odd. If they were worms, it would seem like more
nutrients are available in the shale beds. How many worms do we
usually find crawling in the sand?
I am concerned that you have left out some information (that you
personally disagree with) in the fragments you quote as your sources
and are presenting only the part that you do agree with. You are
entitled to disagree with views different from your own, but to
convince other of your views, you still need to present these opposing
views. You are then entitled to express why you disagree with those
views with point by point commentary if necessary. That is definitely
part of maintaining the integrity of science and _especially_ a genuine
search for truth. If it is really true, the truth eventually does become
clear to your readers without your use of selectivity in presentation.
Indeed, the slightest wind of selectivity greatly lower your credibility
in defending your position.
