Yesterday we noted pterosaur-like pycnofibers (ptero-hairs) on Longsiquama. Here we find them also on Sharovipteryx (Figs. 1, 2), further cementing their relationship to pterosaurs like Sordes, Jeholopterus and others that preserve these extradermal hairs.
If these patterns were wrinkles in neck skin, they would not criss-cross as they do here. They are fiber-like or hair-like and as such may have functioned in thermoregulation, as did the extensive uropatagia behind each hind limb. More likely both were part of their elaborate displays and likely were brightly or contrasted in color and value.
Start making Sharovipteryx hairy, guyz! It joins pterosaurs in being kinda fuzzy, especially around the neck.
As always, I encourage readers to see specimens, make observations and come to your own conclusions. Test. Test. And test again.
