Dinosaur coloration is generally one of the unknowns in the field of paleontology, as skin pigmentation is nearly always lost during the fossilization process. However, recent studies of feathered dinosaurs and skin impressions have shown the colour of some species can be inferred through the use of melanosomes, the colour-determining pigments ...
Sinosauropteryx (meaning "Chinese reptilian wing") is a compsognathid dinosaur.Described in 1996, it was the first dinosaur taxon outside of Avialae (birds and their immediate relatives) to be found with evidence of feathers.
Fossil of Sinornithosaurus millenii, the first evidence of feathers in dromaeosaurids Cast of a Caudipteryx fossil with feather impressions and stomach content Fossil cast of a Sinornithosaurus millenii Jinfengopteryx elegans fossil. Many non-avian dinosaurs were feathered. Direct evidence of feathers exists for the following species, listed in ...
The first rudimentary feathers are thought to have evolved from reptilian scales nearly 250 million years ago in animals ancestral to dinosaurs and the flying reptiles called pterosaurs.
A feathered dinosaur is any species of dinosaur possessing feathers. That includes all species of birds, and in recent decades evidence has accumulated that many non-avian dinosaur species also possessed feathers in some shape or form. The extent to which feathers or feather-like structures were present in dinosaurs as a whole is a subject of ...
The fossilized feathers of Caihong possessed nanostructures which were analyzed and interpreted as melanosomes, showing similarity to organelles that produce a black iridescent color in extant birds. Other feathers found on the head, chest, and the base of the tail preserve flattened sheets of platelet-like melanosomes very similar in shape to ...
The feathers were possibly dark in color to help the dinosaurs with camouflage, visual communication or to absorb more heat in the frigid polar temperatures, the news release said.
