It is relevant how they were formed. Why do you avoid the need for rapid burial and rapid geological processes. Does that need scare you????? Does it call into question your ideas of uniformatarianism and so you find the need to avoid the process? The scablands were also claimed to have taken millions of years, but Harlen Bretz falsified that belief.....
It quite matters how geological processes formed features. Ask Harlen Bretz...
https://en.wikipedia.org/wiki/J_Harlen_Bretz
"Bretz published a paper in 1923, arguing that the channeled scablands in Eastern Washington were caused by massive flooding in the distant past. This was seen as arguing for a catastrophic explanation of the geology, against the prevailing view of uniformitarianism, and Bretz's views were initially discredited. However, as the nature of the Ice Age was better understood, Bretz's original research was vindicated, and by the 1950s his conclusions were also vindicated."
"Bretz encountered resistance to his theories from the geology establishment of the day. The geology establishment was resistant to such a sweeping theory for the origin of a broad landscape for a variety of reasons, including lack of familiarity with the remote areas of the interior Pacific Northwest where the research was based, and the lack of status and reputation of Bretz in the eyes of the largely Ivy League-based geology elites. Furthermore, his theory implied the potential possibilities of a Biblical flood, which the scientific community strongly rejected."

Why would you expect to find more mobile animals trapped in lower sedimentary layers as they struggled upwards to escape the rising waters and the less mobile life was buried? But as I explained.... if you understood how sediments settle.......

Or the less mobile forms unable to escape the rising waters were buried first.........
Polystrate fossils falsify your ideas since those of trees show no root stocks found in the same strata or stigmaria.
Lack of weathering between layers also destroys your beliefs, not that you will ever admit to it...... If the layers actually took hundreds of millions of years, weathering and soil between the differing sedimentary layers would be unavoidable. No such is found......
So perhaps the geological record is trying to tell you something different, but you just refuse to see it... because it might make you question your beliefs about age....
Polystrate fossils showing no affects from the millions of years of weathering they would have been subjected to while the layers formed under your beliefs. No soil layers between the sedimentary layers. No river channels between the layers or any signs of erosion. All the strata is laid down flat, except where later geological processes uplifted them, impossible in reality as we observe the formation of hills and valleys today due to weathering and inconsistent erosion.....
No, it is simply easier to ignore the falsifying evidence....
Not to mention the vast amounts of bones found flattened, which could only occur by rapid burial and pressure before the bones had time to fossilize.... Not sitting around for millions of years as the layers slowly accumulated.....
