Many organisms would have been buried very quickly and fossilized.
We have already discussed how different biases can result in different that it must have always occurred slowly.
If so, then the rock layers must have formed over vast ages.
But because of their naturalistic bias, they prefer, of course, to reject the explanation of the Genesis (global) flood.
However, a cataclysmic globe-covering (and fossil-forming) flood would have eroded huge quantities of sediment, and deposited them elsewhere.
It was found that the same layer thicknesses were reproduced, regardless of flow rate.
