Fancy Feathers In the past few decades, an increasing number of dinosaurs have been shown to have possessed feathers. While it seems likely that feathers themselves may have evolved for thermoregulation, the original function of wings has been less clear and remained a matter of debate. Based on examination of three Theropod specimens from the genus Ornothomimus, Zelenitsky et al. (p. 510) conclude that the feathered wing may have evolved not for locomotion or prey capture (the animals were…

Additional information on the primitive contour and wing feathering of paravian dinosaurs
TLDR
Comparing a range of dinosaur taxa with preserved integumentary appendages using high-resolution photographs to better understand fossil feather morphology and gain insight into their function and evolution suggests that differentiated barbicels are relatively derived compared to pennaceous feathers and the appearance of wings.
Feather Evolution in Pennaraptora
TLDR
The origin and early evolution of complex feathers and flight abilities in paravian theropods were not linear processes, but more complex than previously thought.
Feathered dinosaurs reconsidered: New insights from baraminology and ethnotaxonomy
Birds could not have evolved from land animal ancestors because Genesis clearly states that birds and land animals were created on separate days. As a result, young-earth creationists have…
On the Ancestry of Feathers in Mesozoic Dinosaurs
TLDR
The results provide the first empirical support for the evolution of feathers in an ordered fashion, but reveal that these evolutionary trends were not always towards ‘more complex’ conditions.
Dinosaurs and The Origin of Birds
TLDR
Fossils of feathered dinosaurs with feathers from China provide convincing evidence that birds are coelurosaurs, and that during the course of evolution feathers arose before flight.
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.
Sustained miniaturization and anatomical innovation in the dinosaurian ancestors of birds
TLDR
Bayesian approaches are applied to infer size changes and rates of anatomical innovation in fossils to identify two drivers underlying the dinosaur-bird transition, including the theropod lineage directly ancestral to birds undergoes sustained miniaturization across 50 million years and at least 12 consecutive branches (internodes).

Paravian Phylogeny and the Dinosaur-Bird Transition: An Overview
TLDR
It is concluded that troodontid affinities of anchiornithines, and dromaeosaurids affinITIES of microraptorians and unenlagiids are dismissed in favor of sister group relationships with Avialae, and main phylogenetic hypotheses that compete some topics about the non-avian dinosaur-bird transition are analyzed.

The early evolution of feathers: fossil evidence from Cretaceous amber of France
TLDR
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.
Exceptional dinosaur fossils show ontogenetic development of early feathers
TLDR
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.
A pre-Archaeopteryx troodontid theropod from China with long feathers on the metatarsus
TLDR
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.
A gigantic feathered dinosaur from the Lower Cretaceous of China
TLDR
Morphometric analysis suggests that Y. huali differed from tyrannosaurids in its growth strategy, thus providing direct evidence for the presence of extensively feathered gigantic dinosaurs and offering new insights into early feather evolution.
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.
A new carnivorous dinosaur from the Late Jurassic Solnhofen archipelago
TLDR
A cladistic analysis indicates that the new theropod dinosaur described from the Late Jurassic period of Schamhaupten in southern Germany is closer to maniraptorans than to tyrannosauroids, grouping it with taxa often considered to be compsognathids.
Archaeopteryx and the Origin of Flight
TLDR
The primordial insulative function of contour feathers and the predatory hypothesis for the enlargement of the remiges seem to account for the otherwise paradoxical presence in Archaeopteryx on essentially modern "flight" feathers.
The Predatory Ecology of Deinonychus and the Origin of Flapping in Birds
TLDR
“stability flapping” is described, a novel behaviour executed for positioning and stability during the initial stages of prey immobilisation, which may have been pivotal to the evolution of the flapping stroke.

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.
