For much of the history of paleontology, scientists thought all dinosaurs were covered in scales, like the lizards of today.
"This is strong evidence that the fossil branched structures are feathers comprising a rachis and barbs."According to the researchers' analysis, it's most likely that feathers were inherited from an
common to both dinosaurs and pterosaurs, although it's also possible that these features evolved independently in different groups or species of animals.s ancient plumage appear to have preserved a colorful secret kept hidden for many millions of years. Examining the fossil with high-resolution electron microscopy, the researchers discovered the existence of abundant micro-bodies measuring approximately 0.5–1 μm in length in the animal's soft tissue, and interpreted to be– organelles that hold melanin pigments responsible for different colors in animals' bodies.
The melanosomes had different kinds of shapes , suggesting the pterosaur might have showed a range of colors across its plumage. "In modern birds and mammals, many of the dominant colors of feathers and hair come from a limited range of chemically distinct forms of melanin," explains paleontologist Michael Benton from the University of Bristol in the UK, the author of an
