Spectacular fossils from the Early Cretaceous Jehol Group of northeastern China have greatly expanded our knowledge of the diversity and palaeobiology of dinosaurs and early birds, and contributed to our understanding of the origin of birds, of flight, and of feathers. Pennaceous (vaned) feathers and integumentary filaments are preserved in birds and non-avian theropod dinosaurs, but little is known of their microstructure. Here we report that melanosomes (colour-bearing organelles) are not… 
Melanosome evolution indicates a key physiological shift within feathered dinosaurs
Inference of colour patterning in extinct dinosaurs has been based on the relationship between the morphology of melanin-containing organelles (melanosomes) and colour in extant bird feathers. When
A polar dinosaur feather assemblage from Australia
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.
Three fossilized feathers, consisted of two downy and one contour feather, extracted from the laminated limestone of the Crato Member of the Santana Formation, were described and identified according to morphological and evolutionary models and used the terminology commonly applied to extant organisms.
Reconstruction of Microraptor and the Evolution of Iridescent Plumage
This finding and estimation of Microraptor feathering consistent with an ornamental function for the tail suggest a centrality for signaling in early evolution of plumage and feather color.
Fossilized Feathers
The evolution of feather color, structure, and organization is gleaned from amber-preserved specimens and provides a glimpse of the color patterning in the feathers of ancient birds.
The evolution of the feather: Sinosauropteryx, life, death and preservation of an alleged feathered dinosaur
The signs point strongly to invertebrate colonization of the carcass of Sinosauropteryx rather than vertebrate predation or scavenging, with moderate decay associated with the purge fluids while major decay was forestalled by burial, at most a few days after death.
New evidence on the colour and nature of the isolated Archaeopteryx feather.
The first evidence of colour from Archaeopteryx is reported based on fossilized colour-imparting melanosomes discovered in this isolated feather specimen, and reexamination of the feather's morphology leads it to interpret it as an upper major primary covert, contrary to previous interpretations.
Melanosome diversity and convergence in the evolution of iridescent avian feathers—Implications for paleocolor reconstruction
It is found that iridescence is a labile trait that has evolved convergently in several lineages extending down to paravian theropods and is the most varied melanosome morphologies of all types of bird coloration sampled to date.
Molecular evidence of keratin and melanosomes in feathers of the Early Cretaceous bird Eoconfuciusornis
This work represents the oldest ultrastructural and immunological recognition of avian beta-keratin from an Early Cretaceous (∼130-Ma) bird and sheds new light on molecular preservation within normally labile tissues preserved in fossils.


The colour of fossil feathers
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.
The dinosaurian origin of feathers: perspectives from dolphin (Cetacea) collagen fibers
The early origin of birds is a hotly disputed debate and may be broadly framed as a conflict between paleontologists and ornithologists. The paleontological emphasis has shifted from Archaeopteryx
Do feathered dinosaurs exist? Testing the hypothesis on neontological and paleontological evidence
It is suggested that Aves plus bird‐like maniraptoran theropods (e.g., microraptors and others) may be a separate clade, distinctive from the main lineage of Theropoda, a remnant of the early avian radiation, exhibiting all stages of flight and flightlessness.
A new Chinese specimen indicates that ‘protofeathers’ in the Early Cretaceous theropod dinosaur Sinosauropteryx are degraded collagen fibres
A new specimen of Sinosauropteryx is reported which shows that the integumental structures proposed as protofeathers are the remains of structural fibres that provide toughness.
A dromaeosaurid dinosaur with a filamentous integument from the Yixian Formation of China
Phylogenetic analysis indicates that, among known theropods with integumentary filaments or feathers, Dromaeosauridae is the most bird-like, and is more closely related to birds than is Troodontidae.
Structural coloration in a fossil feather
Investigation of feathers from the famous Middle Eocene Messel Oil Shale near Darmstadt, Germany shows that they are preserved as arrays of fossilized melanosomes, the surrounding beta-keratin having degraded, the first evidence of preservation of a colour-producing nanostructure in a fossil feather.
Evolution of birds: ichthyosaur integumental fibers conform to dromaeosaur protofeathers
The overall findings of the study are that the thesis of dinosaur "protofeathers" requires more substantial support than exists at present.
An Early Cretaceous heterodontosaurid dinosaur with filamentous integumentary structures
Tianyulong extends the geographical distribution of heterodontosaurids to Asia and confirms the clade’s previously questionable temporal range extension into the Early Cretaceous period, and represents the first confirmed report, to the authors' knowledge, of filamentous integumentary structures in an ornithischian dinosaur.
A new maniraptoran dinosaur from China with long feathers on the metatarsus
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.
