The extent to which feathers or feather-like structures were present in dinosaurs as a whole is a subject of ongoing debate and research. It has been suggested that feathers had originally functioned as thermal insulation , as it remains their function in the down feathers of infant birds prior to their eventual modification in birds into ...
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 ...
The description of feathered dinosaurs has not been without controversy in general; perhaps the most vocal critics have been Alan Feduccia and Theagarten Lingham-Soliar, who have proposed that some purported feather-like fossils are the result of the decomposition of collagenous fiber that underlaid the dinosaurs' skin, [257] [258] [259] and ...
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 ...
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 ...
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.
This category contains non-avialian dinosaur genera that have been shown by fossil evidence to have been feathered. Primitive birds belong in Category:Prehistoric birds, though transitional fossils may belong in both. See the article on Fossil birds for a list of early avian taxa.
While it has been known since 2004, upon the description of Dilong, that at least some tyrannosauroids possessed filamentous "stage 1" feathers, [5] according to the feather typology of Richard Prum, Y. huali is currently the largest-known species of dinosaur with direct evidence of feathers, forty times heavier than the previous record holder ...
