Discoveries of bird-like theropod dinosaurs and basal avialans in recent decades have helped to put the iconic ‘Urvogel’ Archaeopteryx into context and have yielded important new data on the origin and early evolution of feathers. However, the biological context under which pennaceous feathers evolved is still debated. Here we describe a new specimen of Archaeopteryx with extensive feather preservation, not only on the wings and tail, but also on the body and legs. The new specimen shows that… Expand
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. Expand
The Feathers of the Jurassic Urvogel Archaeopteryx
TLDR
Feather morphology and arrangement in Archaeopteryx are consistent with lift-generating function, and the wing loading and aspect ratio are comparable to modern birds, consistent with gliding and perhaps flapping flight. Expand
Evidence corroborates identity of isolated fossil feather as a wing covert of Archaeopteryx
TLDR
It is shown that the isolated fossil feather from the Jurassic Solnhofen is most likely an upper major primary covert from the ancient wing of Archaeopteryx, based on its long calamus and eight other anatomical attributes. Expand
New insects feeding on dinosaur feathers in mid-Cretaceous amber
TLDR
A new family of ectoparasitic insects is described from 10 specimens found associated with feathers in mid-Cretaceous amber, demonstrating that feather-feeding behaviors of insects originated at least in mid the Cretaceous, accompanying the radiation of feathered dinosaurs including early birds. Expand
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. Expand
Mosaic evolution in an asymmetrically feathered troodontid dinosaur with transitional features
TLDR
This report reports a new troodontid from the Lower Cretaceous Jehol Group of China that has anatomical features that are transitional between long-armed basal Troodontids and derived short-armed ones, shedding new light on troodonid character evolution and suggests that feather asymmetry was ancestral to Paraves. Expand
Re-evaluation of the Haarlem Archaeopteryx and the radiation of maniraptoran theropod dinosaurs
TLDR
Results indicate an explosive radiation of maniraptoran coelurosaurs probably in isolation in eastern Asia in the late Middle Jurassic and a rapid, at least Laurasian dispersal of the different subclades in the Late Jurassic. Expand
A bony-crested Jurassic dinosaur with evidence of iridescent plumage highlights complexity in early paravian evolution
TLDR
A distinctive new Yanliao theropod species bearing prominent lacrimal crests, bony ornaments previously known from more basal theropods, and a suite of unusual skeletal and feather characteristics consistent with proposed rapid character evolution and significant diversity in signalling and locomotor strategies near bird origins. Expand
A Morphological Review of the Enigmatic Elongated Tail Feathers of Stem Birds
TLDR
As the rhachis-dominated racket plumes combine different morphologies that are apparent among modern feather types, this extinct morphotype does in fact not show any aberrant morphological novelties, but rather fall into the morphological and developmental spectrum of modern feathers. Expand
A Juvenile Specimen of Archaeorhynchus Sheds New Light on the Ontogeny of Basal Euornithines
The ontogenetic development of extant birds is characterized by rapid growth, bone fusion and an early onset of flight ability. In contrast, little is known about how these ontogenetic traits evolvedExpand

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 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. Expand
THE ORIGIN AND EARLY EVOLUTION OF FEATHERS:INSIGHTS FROM RECENT PALEONTOLOGICAL AND NEONTOLOGICAL DATA
TLDR
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. Expand
Reduced plumage and flight ability of a new Jurassic paravian theropod from China.
TLDR
A basal troodontid from the Tiaojishan Formation that resembles Anchiornis is reported that increases the known diversity of small-bodied dinosaurs in the Jurassic, shows that taxa with similar body plans could occupy different niches in the same ecosystem and suggests a more complex picture for the origin of flight. Expand
Unique caudal plumage of Jeholornis and complex tail evolution in early birds
TLDR
Jeholornis reveals that tail evolution was complex and not a simple progression from frond to fan, and probably evolved as the result of complex interactions between natural and sexual selective pressures and served both aerodynamic and ornamental functions. Expand
A Jurassic avialan dinosaur from China resolves the early phylogenetic history of birds
TLDR
The complete skeleton of a new paravian from the Tiaojishan Formation of Liaoning Province, China is described and including it in a comprehensive phylogenetic analysis for basal Paraves recovers Archaeopteryx as the basal-most avialan and implies that the early diversification of Paraves and Avialae took place in the Middle–Late Jurassic period. Expand
Life history of a basal bird: morphometrics of the Early Cretaceous Confuciusornis
TLDR
A multivariate morphometric study involving measurements of more than 100 skeletons of C. sanctus shows any correlation between size distribution and the presence or absence of blade-like rectrices (tail feathers), thus implying, that if these feathers are sexual characters, they are not correlated with sexual size dimorphism. Expand
Structure and function of hindlimb feathers in Archaeopteryx lithographica
TLDR
The presence of the “four-winged” planform in both Archaeopteryx and basal Dromaeosauridae indicates that their common ancestor used fore- and hindlimbs to generate lift, suggesting that arboreal parachuting and gliding preceded the evolution of avian flight. Expand
First Avialian Bird from China
TLDR
A new well-preserved avialian bird from northern Hebei, China is described and phylogenetic analyses have placed it at the root of the avialia family tree, shedding new light on the phylogenetic relationship between non-avian theropods and avian theroids (birds) and on the definition of birds. Expand
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. Expand
