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 fossils show that the dinosaurs had a diversity of tufted hair-like "proto-feathers," which would have been used for insulation. The fossils also showed body and wing feathers that would have ...
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).

With the holotype they were present on the pelvis and near the foot. Specimen ZCDM V5000 had feathers on the tail pointing backwards under an angle of 30 degrees with the tail axis. The smallest specimen showed 20-centimetre-long (7.9 in) filaments on the neck and 16-centimetre-long (6.3 in) feathers at the upper arm. [1]
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 ...
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.
"Regarding discoveries about dinosaurs in recent decades, the most important one to my mind is the discovery that at least meat-eating dinosaurs, theropods, had feathers rather than scales and ...
Coelurosauria is a subgroup of theropod dinosaurs that includes compsognathids, tyrannosaurs, ornithomimosaurs, and maniraptorans; Maniraptora includes birds, the only known dinosaur group alive today. [5] Most feathered dinosaurs discovered so far have been coelurosaurs.
