Did pterosaurs have feathers?

Best Answers

The very name of pterosaurs means "wing lizard", but they weren't feathered wings like bird wings -- their wing surfaces were skin like bats' wings. Another relevant question: Paleontology: Are pterosaur pycnofibers homologous to the feathers of birds? read more

Pterosaurs didn’t necessarily have feathers like what you would find on theropod dinosaurs and birds, but fossils prove they were covered in hair like filaments we call pterosaur pycnofibers. These pycnofibers were made up of protein keratin, just like feathers, scales, and hair. read more

Dinosaurs did not have feathers, they had bristles. Dinosaur to bird proponents misclassify dinosaur bristles as (proto)feathers. There is no connection between the bristles in Coelurosaur dinosaurs and the pennaceous feathers in Pennaraptora/Paraves. read more

Some (Czerkas and Ji, 2002) have speculated that pycnofibers were an antecedent of proto-feathers, but the available impressions of pterosaur integuments are not like the "quills" found on many of the bird-like maniraptoran specimens in the fossil record. read more
