I haven't looked at your flood scenario for a while, but let's acknowledge
that the event you describe above could indeed have moved molluscs,
brachyopods, gastropods and other relatively immobile species to a location
where survival was possible. What evidence would indicate that such an
event had indeed occurred? If you can't point to evidence that such events
occurred, they remain merely speculation.
