In , the discovery of a feathered oviraptorosaurian, Caudipteryx zoui , challenged the notion of feathers as a structure exclusive to Avialae.

Present on the forelimbs and tails, their integumentary structure has been accepted [ by whom? In the clade Deinonychosauria, the continued divergence of feathers is also apparent in the families Troodontidae and Dromaeosauridae.

Branched feathers with rachis, barbs, and barbules were discovered in many members including Sinornithosaurus millenii , a dromaeosaurid found in the Yixian formation Previously, a temporal paradox existed in the evolution of feathers—theropods with highly derived bird-like characteristics occurred at a later time than Archaeopteryx —suggesting that the descendants of birds arose before the ancestor.

By predating Archaeopteryx , Anchiornis proves the existence of a modernly feathered theropod ancestor, providing insight into the dinosaur-bird transition.

The specimen shows distribution of large pennaceous feathers on the forelimbs and tail, implying that pennaceous feathers spread to the rest of the body at an earlier stage in theropod evolution.

Filamentous feathers are preserved alongside modern-looking flight feathers — including some with modifications found in the feathers of extant diving birds — in 80 million year old amber from Alberta.

Two small wings trapped in amber dating to mya show plumage existed in some bird predecessors. The wings most probably belonged to enantiornithes , a diverse group of avian dinosaurs.

A large phylogenetic analysis of early dinosaurs by Matthew Baron, David B. Norman and Paul Barrett found that Theropoda is actually more closely related to Ornithischia , to which it formed the sister group within the clade Ornithoscelida.

The study also suggested that if the feather-like structures of theropods and ornithischians are of common evolutionary origin then it would be possible that feathers were restricted to Ornithoscelida.

If so, then the origin of feathers would have likely occurred as early as the Middle Triassic. Several studies of feather development in the embryos of modern birds, coupled with the distribution of feather types among various prehistoric bird precursors, have allowed scientists to attempt a reconstruction of the sequence in which feathers first evolved and developed into the types found on modern birds.

Feather evolution was broken down into the following stages by Xu and Guo in [84]. However, Foth showed that some of these purported stages stages 2 and 5 in particular are likely simply artifacts of preservation caused by the way fossil feathers are crushed and the feather remains or imprints are preserved.

Foth re-interpreted stage 2 feathers as crushed or misidentified feathers of at least stage 3, and stage 5 feathers as crushed stage 6 feathers.

The following simplified diagram of dinosaur relationships follows these results, and shows the likely distribution of plumaceous downy and pennaceous vaned feathers among dinosaurs and prehistoric birds.

The diagram follows one presented by Xu and Guo [84] modified with the findings of Foth Note that 's' indicates the known presence of scales on the body.

Psittacosauridae s, 1. Dilong 3? Pterosaurs were long known to have filamentous fur-like structures covering their body known as pycnofibres , which were generally considered distinct from the "true feathers" of birds and their dinosaur kin.

However, a study of two small, well-preserved pterosaur fossils from the Jurassic of Inner Mongolia , China indicated that pterosaurs were covered in an array of differently-structured pycnofibres rather than just filamentous ones , with several of these structures displaying diagnostic features of feathers, such as non-veined grouped filaments and bilaterally branched filaments, both of which were originally thought to be exclusive to birds and other maniraptoran dinosaurs.

Given these findings, it is possible that feathers have deep evolutionary origins in ancestral archosaurs , though there is also a possibility that these structures independently evolved to resemble bird feathers via convergent evolution.

Therefore, because they are the same, they must share an evolutionary origin, and that was about million years ago, long before the origin of birds. From Wikipedia, the free encyclopedia.
