The discovery of Sinosauropteryx in 1996 marks the beginning of a new era in the research on the origin and early evolution of feathers. Subsequent discoveries of dinosaur fossils preserving feathers and feather-like integumentary appendages from both the Jurassic and Cretaceous deposits of China and other countries demonstrate a longer and more complex evolutionary history of feathers before the origin of birds than was previously thought. Currently, there are still many issues that continue… 

Variations of Mesozoic feathers: Insights from the morphogenesis of extant feather rachises

Rachises of RDFs are developmentally equivalent to a variety of immature stages of cylindrical rachises, suggesting they are not unique to Mesozoic theropods, although they are likely to have evolved independently in extant penguins.

Epidermal complexity in the theropod dinosaur Juravenator from the Upper Jurassic of Germany

Epidermal scales among modern reptiles are morphologically diverse and serve a variety of functions ranging from moisture balance to chemoreception. Despite being predominantly squamous‐skinned

Morphology and distribution of scales, dermal ossifications, and other non‐feather integumentary structures in non‐avialan theropod dinosaurs

The morphology and distribution of non-feathered integumentary structures in non-avialan theropods, covering squamous skin and naked skin as well as dermal ossifications are reviewed.

The Origin of Birds: Current Consensus, Controversy, and the Occurrence of Feathers

Research in the late 1900s has established that birds are theropod dinosaurs, with the discovery of feather preservation in non-avian theropods being the last decisive evidence for the dinosaur

Caenagnathids of the Dinosaur Park Formation (Campanian) of Alberta, Canada: anatomy, osteohistology, taxonomy, and evolution

Our understanding of caenagnathid anatomy, diversity, and ecology has improved considerably in the past twenty years, but numerous issues still remain. Among these, the diversity and taxonomy of

Estimating the distribution of carotenoid coloration in skin and integumentary structures of birds and extinct dinosaurs

Support is found that expression of carotenoid‐consistent color in nonplumage integument structures might evolve in a correlated manner and feathers are rarely the only region of expression.

Chapter 10 Methods of studying early theropod flight

This chapter will survey key methods and approaches, covering their best-practice applications along the timeline of early theropod flight evolution and priorities for future method development.



Branched integumental structures in Sinornithosaurus and the origin of feathers

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.


Five major morphogenesis events are inferred to have occurred sequentially early in feather evolution before the origin of the Aves, and the function of the first feather is inferred to be neither related to flight nor to insulation.

Exceptional dinosaur fossils show ontogenetic development of early feathers

An early-juvenile specimen and a late- juvenile specimen, both referable to the oviraptorosaur Similicaudipteryx, recovered from the Lower Cretaceous Yixian Formation of western Liaoning, China are described, suggesting that early feathers were developmentally more diverse than modern ones and that some developmental features have been lost in feather evolution.

New specimen of Archaeopteryx provides insights into the evolution of pennaceous feathers

An analysis of the phylogenetic distribution of pennaceous feathers on the tail, hindlimb and arms of advanced maniraptorans and basal avialans strongly indicates that these structures evolved in a functional context other than flight, most probably in relation to display, as suggested by some previous studies.

The morphology of neoptile feathers: Ancestral state reconstruction and its phylogenetic implications

The morphology of neoptile feathers is more diverse and even shows a clear phylogenetic signal, and it is necessary to expand the spectrum of “model organisms” to species with bilaterally symmetric ne optile feathers and compare differences in the frequency of feather development from a phylogenetic point of view.

The early evolution of feathers: fossil evidence from Cretaceous amber of France

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 the fossil records is reported.

The Evolutionary Origin And Diversification Of Feathers

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.

A Jurassic ornithischian dinosaur from Siberia with both feathers and scales

A seemingly feathery nontheropod dinosaur from the Jurassic of Siberia shows that feathers were not unique to the ancestors of birds and may even have been quite widespread, and feathers may thus have been present in the earliest dinosaurs.

A series of fossil discoveries representing intermediate forms of feathers or feather-like appendages from dinosaurs and Mesozoic birds from the Jehol Biota of China are reviewed and a set of criteria for true avian feathers is developed.

A pre-Archaeopteryx troodontid theropod from China with long feathers on the metatarsus

The extensive feathering of this specimen, particularly the attachment of long pennaceous feathers to the pes, sheds new light on the early evolution of feathers and demonstrates the complex distribution of skeletal and integumentary features close to the dinosaur–bird transition.
