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 ...
In all examples, the evidence described consists of feather impressions, except those genera inferred to have had feathers based on skeletal or chemical evidence, such as the presence of quill knobs (the anchor points for wing feathers on the forelimb) or a pygostyle (the fused vertebrae at the tail tip which often supports large feathers).

Sinosauropteryx (meaning "Chinese reptilian wing") is an extinct genus of coelurosaurian theropod dinosaurs.Described in 1996, it was the first dinosaur taxon outside of Avialae (birds and their immediate relatives) to be found with evidence of feathers.
A new study shows that fluffy dinosaurs actually existed and roamed the South Pole. ... The fossils show that the dinosaurs had a diversity of tufted hair-like "proto-feathers," which would have ...
Psittacosaurus had simple, bristle-like feathers atop its tail. The rest of its body was covered by scaly skin. The fossil did not have skin from the dinosaur's feathered regions, but the ...
Most feathered dinosaurs discovered so far have been coelurosaurs. Philip J. Currie had considered it likely and probable that all coelurosaurs were feathered. [6] However, several skin impressions found for some members of this group show pebbly, scaly skin, indicating that feathers did not completely replace scales in all taxa.
A few years ago, Maria McNamara was invited to Brussels by fellow paleontologist Pascal Godefroit and presented with an intriguing opportunity.
The description of feathered dinosaurs has not been without controversy in general; perhaps the most vocal critics have been Alan Feduccia and Theagarten Lingham-Soliar, who have proposed that some purported feather-like fossils are the result of the decomposition of collagenous fiber that underlaid the dinosaurs' skin, [257] [258] [259] and ...
