I heard a while back that there's some evidence for Crocodilians having fuzz at some point, based on alligator genetics. I have two questions. 1, is this true? and 2, if this is true, could it be that archosaurs evolve and then lose fuzz multiple times independently of each other? So Archosaurs are fuzz, then lose the fuzz, then re-evolve it? And this could explain how, if the Befuckening is true, feathered dinosaurs and pterosaurs could both exist without sharing a fuzzy ancestor?
It’s not true - the only thing the paper in question said was that feathers and croc scales were made of the same kind of keratin. Hardly means crocs had the blueprint for feathers.
More research is needed of course, as no one in development has looked for feather development genes in crocs, so the jury on that is still out.
If they are, however, ancestral to archosaurs, that would just mean pseudosuchians lost them. The common ancestor of pterosaurs and dinosaurs would still be fluffy.
