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 ...
While Sinosauropteryx had feather-like structures, it was not very closely related to the previous "first bird" Archaeopteryx. [2] There are many dinosaur clades that were more closely related to Archaeopteryx than Sinosauropteryx was, including the deinonychosaurians, the oviraptorosaurians, and the therizinosauroids. [8]

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).

The fossil did not have skin from the dinosaur's feathered regions, but the researchers think these areas had bird-like skin. "This discovery adds nuance to our understanding of feather evolution.
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]
“Feathers aren’t just a bird thing, or even just a dinosaur thing, but evolved deeper in time.” The 113-million-year-old fossil is preserved within four limestone slabs. The partial skull ...
