How does a formation preserve a topography?
It buries the topography, fills in the lows until the area is flat again.
But the odds of their being preserved/fossilized is extremely remote.
Preservation is uncommon, but locally very abundant.
By the way I've been wondering why all that vegetation ended up in the Carboniferous "period" where it turned into coal, while I gather the strata in which the dinosaurs are buried don't have much vegetation though ...
How come?
We have dinosaur tracks in coal seams. The fact that they got preserved in rapidly deposited sand bars is no freak accident.
... of all animals they would have needed a prodigious amount of it.
There are plenty of plant fossils in the Cretaceous and Paleogene rocks that I have drilled.
There's no problem of course on the Flood model since the "Carboniferous" is merely a layer where the vegetation got deposited and not a time period, but it doesn't make a lot of sense on the Geo Time Scale model that so much is found there and not with the dinosaurs.
That is a silly notion. You are saying that entire swamps with dinosaur tracks and all, are somehow picked up by a turbulent fludde, transported on a tempestuous sea, and then gently deposited, en masse, by a receding sea in which waves don't tear up the organic mass?
Not gonna work...
