Pterosaur melanosomes support signalling functions for early feathers
- Biology, Environmental ScienceNature
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.
- Environmental ScienceNature ecology & evolution
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.

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

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

New interpretation of the wings of the pterosaur Rhamphorhynchus muensteri based on the Zittel and Marsh specimens
- BiologyJournal of Paleontology
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…

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…
