In my mind, I imagine the initial stages of the Flood (it took at least 40 days, perhaps 150 to completely cover the earth) having many events similar to the recent tsunami but perhaps more violent than the recent one. Did you notice how many of the animals vacated the areas? So only mostly sea life and curious humans would be found in the mud there (also the mud is probably not rich in carbonate--limestone in solution, right?--as the Flood waters are thought to have been--there being limestone everywhere today).
I have no idea what you are trying to say here. The tsunami mechanism of the great flood has been completely discredited. By the way, more violent tsunamis are documented as having killed many terrestrial creatures.
Okay...so most animals and humans (assuming the humans could somehow know the danger) escaped the initial tsunamis. But they came again and further inland and again and further inland and again and further inland. At some point in time, the animals might well find themselves running across carbonate-rich mud left from a previous tsunami, which partially lithified, only to be covered up by more sediments from more tsunamis.
You are reaching here. Why would a tsunami deposit carbonate muds? Why would the muds survive numerous tsunami events? Why would 100% of terrestrial animals survive the first xteen kilometers of sedimentation? Why would flowering plants survive longer than dinosaurs? There is an explanation for all this:
there is no evidence whatsoever of a biblical scale flood.
I'm thinking mud-rich tsunamis again. Perhaps these eggs and nests were on the out skirts of the destruction by some of the initial tsunamis so as to get covered by mud but not crushed. Then after covered by that layer of mud another tsunami comes further inland covering that layer of mud, and so forth.
So the first dinosaur nests were not covered until the Mesozoic? Even though we have dinosaur habitat, footprints, etc. in coastal swamps?
Actually I am curious how conventional geology posits that dinosaur eggs fossilized, given that eggs are popular fare by most critters and they rot quickly if not hatched (and many are found in the process of hatching or with nearly fully formed baby dinos ready to hatch.) Fossilized dino eggs are not exactly rare, but shouldn't they be?
Some are covered by wind-blown sand, just as many organisms are buried today. Considering that any creature might try to select a protected place for a nest, I don't see this as terribly inconsistent with natural processes.
Do creationists propose this? I'm not sure. Why do you think they must?
Well, it is a logical conclusion from the YEC premise. Where do the coral reefs come from? How did they survive the flood? How did they grow such immense colonies in just a couple of thousand years? These are questions you need to ask.
I'll give the unconformities a shot. Tsunamis, landslides, etc. occur during the initial 40 - 150 days. In some cases the, layers are layed down at one angle. The global stress causes plate movement of some sort (CPT or not), which changes the angles of the dryish land. The next tsunami, which due to increased water levels is higher might well remove some of the previous sediments (which are now at a different angle) and redeposit at the new angle.
And how did those rocks manage to lithify in less than a year at the surface of the earth? Never mind the fact that we do not see any tsunami-type sedimentation. You should be getting the idea that tsunamis have been evoked before by YECs and been thoroughly shot down.
I haven't studied eolian sand dunes, but it does intrigue me that there are lithified "sand dunes" in the layers. I should probably try to do a little research on this, too.
I recommend avoiding the YEC literature on this. You will only get part of the picture.
