On the preservation thing, it depends but it usually comes down tp either skin impressions, soft tissue fossilization, or imprints kinda like fossil footprints. You were basically on point with your guess. But yeah this type of evidence is varried and highly temperamental in how we find it.
I think the only thing that preserves worse are soft bodied organisms like jellyfish. But yeah if ya want to learn more on this shit PBS Eons on youtube is a pretty solid start.

Thanks! I can imagine preserving a feather for 65 millions of years is no easy feat.
