Forams generally live in deep sea levels. I can't imagine them being deposited by the flood. Where were the fossils found? Which layers? Do you have an article that elaborates on this?
Forams live in all depths, surface to bottom. They are used to correlate zones in the oil-producing formations in South Louisiana to at least four miles deep, to my own work-related knowledge.
Bolivina mexicana, for instance, occurs at about 15,000 feet deep at Rayne, Louisiana. Other species occur in other strata up to near-surface.
Foraminifera is an overview - I can't seem to find the Gulf Coast correlation chart that I once had though. I Googled in before, so surely it's out there. Or not.
