Seeing how ~100 mya Cretaceous amber from Burma shows insects directly associated with feathers, preening makes sense as a behavior then. Here's to hoping both insects & feathers show up in those coprolites! https://www.nature.com/articles/s41467-019-13516-4 … #ichnology

Literally anything poop-related is fantastic, but I'm waiting with bated breath on what could be inside those coprolites, Jim! The deposition relative to skeletal material is also really fascinating.
