>>>In other words, can fossils "wash down" from an older formation into a younger one? PMFJI. In a word, Yes. That's the whole issue with Dinosaur remains found above the KT boundary in the Northern Great Plains — it isn't clear whether they are in place and therefore are of Paleocene Age, or are redeposited from Cretaceous beds. I believe that there have been cases of misdating of formations based on redeposited fossils, but none pop to mind.
