Erosion, yes. We recognize erosion in the geological record frequently. I am not sure what you mean by mass erosion. At any rate mass wasting is not usually a problem in constructing a geological column. I don't think radiation has much to do with the position of fossils.

also would it be possible for the bones to sift downward in the ground into another layer?
Probably not, but even if it did happen, we would have a very different fossil record. Extremely mixed up if nothing else.

maybe at one point there was an underground river that shifted a few of the fossils around and changed the order, even though there would be evidence of this the underfround river might have been caved in on by dirt from the surface.
That would have to be on very unusual river to rearrange the entire fossil record in different locations on several continents...

the less advanced lifeforms might have lived underground and found more food where they were eventually fossilized.
I think you are grasping here.
