The developmental stages of feathers are of major importance in the evolution of body covering and the origin of avian flight. Until now, there were significant gaps in knowledge of early morphologies in theoretical stages of feathers as well as in palaeontological material. Here we report fossil evidence of an intermediate and critical stage in the incremental evolution of feathers which has been predicted by developmental theories but hitherto undocumented by evidence from both the recent and… 

Figures from this paper

New evidence of feathers in the Crato Formation supporting a reappraisal on the presence of Aves.

TLDR
The preservation of delicate structures such as feathers is very rare in the paleontological record, due to the fragility of their components, and the presence of an asymmetrical feather without barbules and hooks hints at the previous existence of a flightless animal within this deposit.

Feathered Non-Avian Dinosaurs from North America Provide Insight into Wing Origins

TLDR
The Ornithomimus specimens, recovered from Upper Cretaceous deposits of Alberta, Canada, provide new insights into dinosaur plumage and the origin of the avian wing, and show that primordial wings originated earlier than previously thought, among non-maniraptoran theropods.

New occurrences of fossilized feathers: systematics and taphonomy of the Santana Formation of the Araripe Basin (Cretaceous), NE, Brazil

TLDR
Feathered non-avian dinosaurs have not yet been described from the Crato Member, even though there are suggestions of their presence in nearby basins, and it is revealed that, despite the small sample size, they can be referred to coelurosaurian theropods.

Ornamental feathers in Cretaceous Burmese amber: resolving the enigma of rachis-dominated feather structure

Over the last 20 years, compression fossils of feathers surrounding dinosaurs have greatly expanded our understanding of the origin and evolution of feathers. One of the most peculiar feather

Filamentous Integuments in Nonavialan Theropods and Their Kin: Advances and Future Perspectives for Understanding the Evolution of Feathers

TLDR
F fossil specimens will continue to provide key data for the reconstruction and documentation of the evolutionary history of feathers, including evolutionary experiments and forms that no longer occur in nature.

Mummified precocial bird wings in mid-Cretaceous Burmese amber

TLDR
These specimens demonstrate that the plumage types associated with modern birds were present within single individuals of Enantiornithes by the Cenomanian, providing insights into plumage arrangement and microstructure alongside immature skeletal remains.

Silicification of feathers in a modern hot spring in New Zealand

Fossil feathers have greatly improved our understanding of the evolutionary transition from non-avian dinosaurs to birds and the evolution of feathers, and may be the only evidence for their source

A Diverse Assemblage of Late Cretaceous Dinosaur and Bird Feathers from Canadian Amber

TLDR
Late Cretaceous coal-rich strata from western Canada provide the richest and most diverse Mesozoic feather assemblage yet reported from amber, offering new insights into their structure and function.

Feathered dinosaurs from China and the evolution of major avian characters.

TLDR
An evolutionary model is proposed here to describe the major stages of feather evolution, a process characterized by a combination of both transformational and innovative modifications.

Explanatory History of the Origin of Feathers1

TLDR
It is argued that test of historical-narrative evolutionary explanations, including classifications and phylogenies, is generally difficult to impossible because of the lack of the necessary objective empirical observations.

The Evolutionary Origin And Diversification Of Feathers

TLDR
The developmental theory proposes that feathers evolved through a series of evolutionary novelties in developmental mechanisms of the follicle and feather germ, and the discovery of primitive feather fossils on nonavian theropod dinosaurs documents that feathers evolve and diversified in nonavIAN theropods before the origin of birds and before theorigin of flight.

TLDR
A functionally neutral model of the origin and evolutionary diversification of bird feathers based on the hierarchical details of feather development is proposed, predicting that feathers originated with the evolution of the first feather follicle-a cylindrical epidermal invagination around the base of a dermal papilla.

Unusual Early Cretaceous birds from Spain

TLDR
A new Spanish fossil bird that lacks the skull is reported, which presents a combination of derived (strut-like coracoids, pygostyle) and primitive (pelvic girdle, sacrum, hind limb) character states.

Branched integumental structures in Sinornithosaurus and the origin of feathers

TLDR
Observations of the filamentous integumental appendages of the basal dromaeosaurid dinosaur Sinornithosaurus millenii indicate that they are compound structures composed of multiple filaments that are unique to avian feathers, which strongly corroborate the hypothesis that the integumentals of SinORNithosaurus are homologous with avan feathers.

A new maniraptoran dinosaur from China with long feathers on the metatarsus

TLDR
A new eumaniraptoran theropod from China, with avian affinities, is reported, which also has long pennaceous feathers on its feet, suggesting that such morphology might represent a primitive adaptation close to the theropOD–bird transition.

Basal tyrannosauroids from China and evidence for protofeathers in tyrannosauroids

TLDR
A new basal tyrannosauroid from the Early Cretaceous Yixian Formation of western Liaoning, China, which is small and gracile and has relatively long arms with three-fingered hands and provides the first direct fossil evidence that Tyrannosauroids had protofeathers.

Two feathered dinosaurs from northeastern China

TLDR
Two theropods from the Upper Jurassic/Lower Cretaceous Chaomidianzi Formation of Liaoning province, China are described, which represent stages in the evolution of birds from feathered, ground-living, bipedal dinosaurs.
