Neither of those arguments is good, unsurprisingly.
That does not fit with those strata I cited either, as the faunas in them reflect the following sequence (with transitions between each state), going down:
Land
~2 m depth
Land
~15 m depth
Land
~15 m depth
Land
~50 m depth
Land
~70 m depth
Land
~40 m depth
Land
[repeat last step about 6 times]
~100 m depth
Land
[repeat several times]
~250 m depth
etc.
Those same layers refute that claim as well, given their contents:
shark’s teeth, some sturdy mollusks
mollusks, some marine fish, echinoderms, barnacles, foraminifera, etc.
[repeat last set a bunch of times]
mollusks, mosasaur teeth, dinosaurs
bedrock
How are corals or oysters better at escaping floodwaters than dinosaurs are?
