Pterosaur melanosomes support signalling functions for early feathers
TLDR
The presence of diverse melanosome geometries in the skin and simple and branched feathers of a tapejarid pterosaur from the Early Cretaceous found in Brazil indicate that manipulation of feather colour—and thus functions of feathers in visual communication—has deep evolutionary origins.
Reply to: No protofeathers on pterosaurs.
TLDR
The morphology, ultrastructure and chemistry of the dermal structures of pterosaurs from China showed that they probably had a common evolutionary origin with the integumentary structures seen widely in dinosaurs (including birds), their close relatives, and was to shift the origin of feathers back 100 Myr before Archaeopteryx, one of the first birds.

Pterosaurs
TLDR
150 million years ago, an animal no bigger than a herring gull soared above shallow lagoons in what is now Bavaria and crashed into the water and sank to its anoxic depths, where it was eventually buried by layers of lime.
On the Ancestry of Feathers in Mesozoic Dinosaurs
TLDR
The results provide the first empirical support for the evolution of feathers in an ordered fashion, but reveal that these evolutionary trends were not always towards ‘more complex’ conditions.
Chemical characterization of pterosaur melanin challenges color inferences in extinct animals
TLDR
Chemically characterize the melanin content of the soft tissue headcrest of the pterosaur Tupandactylus imperator by alkaline hydrogen peroxide oxidation followed by high-performance liquid chromatography and demonstrate the unequivocal presence of eumelanin in T. imperatorHeadcrest.

New interpretation of the wings of the pterosaur Rhamphorhynchus muensteri based on the Zittel and Marsh specimens
Abstract. The Zittel wing of Rhamphorhynchus muensteri is reinterpreted as preserving negative impressions of closely spaced broad flat actinofibrils that were replaced by calcite but were prepared
Middle- and bottom-decker Cretaceous pterosaurs: unique designs in active flying vertebrates
Abstract Among Pterosauria there are three types of scapulocoracoid construction. In the ornithocheirid scapulocoracoid the scapula is oriented almost horizontally; it is shorter than the coracoid
