Eighteen inch long human footprints have been found in Cretaceous solidified mud in the bed of the Paluxy River in Texas, along with normal footprints and dinosaur prints. This poured out over the land to provide great depths of pure clays, sands etc. There would not have been enough time in the one year of the Flood to erode mountains to provide the vast volumes of clays ans sands etc. Animals often found entombed in an attitude of fear - head back, mouth open, fins, wings extended etc. This indicates they were overwhelmed in a rapid inundation.
Fossilisation requires rapid inundation.
Today, bones just disintegrate. This sequence is a perfectly satisfactory explanation of the order in which the various fossils are found in the strata. It is NOT the order in which they evolved but the order in which they were inundated at the time of Noah's flood. The geological strata are extremely complicated, and trying to interpret the whole sequence in a Biblical framework is extremely difficult. The atmosphere now has clouds and raindrops and the first rainbow is now visible.
