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 phylogeny of Compsognathidae organizes this family near the development of feathers in dinosaurs. In 1998, evidence of filamentous protofeathers was presented in a study on Sinosauropteryx , marking the first time that any sort of feather structure was found outside of birds and their related species.

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.
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.
The group (along with all maniraptoran dinosaurs) is close to the ancestry of birds. Some researchers such as Maryanska et al (2002) and Osmólska et al. (2004) have proposed that they may represent primitive flightless birds. [3] [4] The most complete oviraptorosaur specimens have been found in Asia. [5]
Oviraptorids were probably feathered, since some close relatives were found with feathers preserved (including species of Caudipteryx, Protarchaeopteryx and Similicaudipteryx). [ 17 ] [ 18 ] Another finding pointing to this is the discovery in Nomingia of a pygostyle , a bone that results from the fusion of the last tail vertebrae and is ...
What was 21-feet tall, looked like a T-rex and was covered in feathers? It was the Cryolophosaurus, of course! This eccentric beast roamed the Earth during the early Jurassic Period, around 188 to ...
