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.
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).

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 ...
Caudipteryx (meaning "tail feather") is a genus of small oviraptorosaur dinosaurs that lived in Asia during the Early Cretaceous, around 124.6 million years ago.They were feathered and extremely birdlike in their overall appearance, to the point that some paleontologists suggested it was a bird.
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.
Beipiaosaurus was a small therizinosaur, measuring 2.2 m (7.2 ft) in length, and before the discovery of Yutyrannus they were the largest dinosaurs known from direct evidence to be feathered. [1] It is estimated to have weighed about 27 kg (60 lb) based on femur length. [ 7 ]
The pterosaur suggests feathers emerged around 250 million years ago through the common ancestor of dinosaurs, birds and pterosaurs -- and shifts the origin of feathers to 100 million years ...
