Feathers have long been regarded as the innovation that drove the success of birds. However, feathers have been reported from close dinosaurian relatives of birds, and now from ornithischian dinosaurs and pterosaurs, the cousins of dinosaurs. Incomplete preservation makes these reports controversial. If true, these findings shift the origin of feathers back 80 million years before the origin of birds. Gene regulatory networks show the deep homology of scales, feathers, and hairs. Hair and… Expand

Figures and Topics from this paper

Down feather morphology reflects adaptation to habitat and thermal conditions across the avian phylogeny
TLDR
It is shown that habitat has a very strong and clearly defined effect on down feather morphology, and characters of convergent evolution in the avian plumage and mammalian fur are revealed, that match the varying needs of insulation in terrestrial and aquatic modes of life. Expand
The origin of endothermy in synapsids and archosaurs and arms races in the Triassic
Abstract Birds and mammals are key elements of modern ecosystems, and many biologists explain their great success by their endothermy, or warm-bloodedness. New palaeontological discoveries point toExpand
Cretaceous amniote integuments recorded through a taphonomic process unique to resins
TLDR
Two Spanish Cretaceous amber pieces that are of taphonomic importance are described, one bearing avian dinosaur feather remains and the other, mammalian hair, which were recorded through a rare biostratinomic process called “pull off vestiture” different from the typical resin entrapment and embedding of organisms and biological remains, and unique to resins. Expand
The Making of a Flight Feather: Bio-architectural Principles and Adaptation
TLDR
Quantitative bio-physical analyses of feathers from birds with different flight characteristics and feathers in Burmese amber reveal how multi-dimensional functionality can be achieved and may inspire future composite material designs. Expand
Three-dimensionally preserved ‘Stage IIIb’ fossil down feather supports developmental modularity in feather evolution
TLDR
The topology of this down feather, consistent with specific patterns of modular protein-protein signalling already observed, provides the first definitive evidence that such signalling was responsible for the evolution of a diverse inventory of feather morphologies in non-avialan dinosaurs and early birds since the middle Jurassic. Expand
Volant Fossil Vertebrates: Potential for Bioinspired Flight Technology.
TLDR
The latest knowledge and literature regarding flight performance in fossil vertebrates is reviewed and key elements are synthesised to provide an overview of those cases where fossil flyers might provide new insights for applied sciences. Expand
Making region-specific integumentary organs in birds: evolution and modifications.
TLDR
It is shown that this complexity is built upon multi-level regional specifications that includes the evolution of beaks and feathers as new integumentary organs that are formed with regional specificity. Expand
Reply to: No protofeathers on pterosaurs.
TLDR
The morphology, ultrastructure and chemistry of the dermal structures of pterosaurs from China showed that they probably had a common evolutionary origin with the integumentary structures seen widely in dinosaurs (including birds), their close relatives, and was to shift the origin of feathers back 100 Myr before Archaeopteryx, one of the first birds.

Abstract Much of the focus of palaeobiological studies in the last century can be summarized as seeking to understand how evolutionary lineages occupy new regions of morphological, ecological, andExpand
Evaluation of the effectiveness of cryptic coloration of the Carolina anole’s skin
TLDR
The relativity of visual hiding of the skin that is effective only in the habitat conditions in which the camouflage abilities of theSkin camouflage index is confirmed, which indicates a greater vulnerability of the animal to external threats. Expand

The molecular evolution of feathers with direct evidence from fossils
TLDR
It is confirmed here that feathers were modified at both molecular and morphological levels to obtain the biomechanical properties for flight during the dinosaur–bird transition, and it is shown that the patterns and timing of adaptive change at the molecular level can be directly addressed in exceptionally preserved fossils in deep time. Expand
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. Expand
A Jurassic ornithischian dinosaur from Siberia with both feathers and scales
TLDR
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. Expand
Melanin Concentration Gradients in Modern and Fossil Feathers
TLDR
It is observed that the contour feather pattern was found most frequently in distantly related groups that share aquatic ecologies (e.g. waterfowl Anseriformes, penguins Sphenisciformes), suggesting a potential adaptive function with ancient origins. Expand
Evolution of dinosaur epidermal structures
TLDR
Using a comprehensive database of dinosaur skin traces, maximum-likelihood methods are applied to reconstruct the phylogenetic distribution of epidermal structures and interpret their evolutionary history. Expand
The colour of fossil feathers
TLDR
It is concluded that most fossil feathers are preserved as melanosomes, and that the distribution of these structures in fossil feathers can preserve the colour pattern in the original feather. Expand
The morphogenesis of feathers
TLDR
The replication-competent avian sarcoma retrovirus is used to deliver exogenous genes to regenerating flight feather follicles of chickens, and it is shown that the antagonistic balance between noggin and bone morphogenetic protein 4 (BMP4) has a critical role in feather branching. Expand
Fossilized skin reveals coevolution with feathers and metabolism in feathered dinosaurs and early birds
TLDR
Examination of fossil skin from feathered dinosaurs and ancient birds from the Cretaceous and show the early acquisition of many skin attributes seen in modern species, confirming that basal birds and non-avian dinosaurs shed small epidermal flakes as in modern mammals and birds, but structural differences imply that these Cretsaceous taxa had lower body heat production than modern birds. Expand
New specimen of Archaeopteryx provides insights into the evolution of pennaceous feathers
TLDR
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. Expand
Fossil Evidence for Evolution of the Shape and Color of Penguin Feathers
TLDR
The fossil reveals that key feathering features, including undifferentiated primary wing feathers and broad body contour feather shafts, evolved early in the penguin lineage, and analyses of fossilized color-imparting melanosomes reveal that their dimensions were similar to those of non-penguin avian taxa and that the feathering may have been predominantly gray-brown.
