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 ...
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.
Fossil of Sinornithosaurus millenii, the first evidence of feathers in dromaeosaurids Cast of a Caudipteryx fossil with feather impressions and stomach content Fossil cast of a Sinornithosaurus millenii Jinfengopteryx elegans fossil. Many non-avian dinosaurs were feathered. Direct evidence of feathers exists for the following species, listed in ...
"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 ...
In addition, the two adult specimens had distinctive, "wavy" crests on their snouts, on both sides of a high central crest, which were probably used for display. The presence of feathers on a large basal tyrannosauroid suggests the possibility that later tyrannosaurids were also feathered, even when adult, despite their size. [ 1 ]
The fossil points to "zoned development" in the skin of these dinosaurs, researchers said, with Psittacosaurus and probably other feathered dinosaurs possessing scaly, reptile-like skin on body ...
Since T. rex and other theropods (a group of land-dwelling, carnivorous dinosaurs) spent most of their time on land, they probably had lips too. So, nope — probably not the toothy, terrifying ...
