2 papers regarding pterosaurs with integument and melanosomes (Cascocauda and Tupandacytlus)

[Faelrin]

Cascocauda's paper is paywalled unfortunately, but from what I gleaned from the wikipedia article is that is well preserved juvenile pterosaur complete with integument and melanosomes.

Relevant article that shows an image of the holotype specimen that featured in an earlier article from 2019:

Another paper on Tupandactlyus shows it has some integument on the head, and covers the different types of filaments it has. It also goes into some detail about the melanosomes it has and the implications of those (such as being similar to theropod dinosaurs, etc). This one does not seem to be paywalled.

Normally when I see the word melanosomes I think of coloration, but I don't think the above paper really delved into that as much as the potential evolution of the filaments. That in itself is also interesting, but well of course I can't help but wonder now if we have the slightest idea of what either pterosaur's colors may have been like, if they have melanosomes?

Also pycnofibers are feathers now? Am I understanding the above paper right? I really am not as familiar with pterosaurs so any help here would be appreciated.

Yeah, they seem to be accepting the claim that pycnofibers are essentially feathers, which is by no means certain, but to my mind seems possible. It's based on a couple of Jeholopterus specimens with integument that was (controversially) interpreted as having a branched, featherlike structure.
