Some nonavian theropod dinosaurs were at least partially covered in feathers or filamentous protofeathers. However, a complete understanding of feather distribution among theropod dinosaurs is limited because feathers are typically preserved only in lagerst�tten like that of Solnhofen, Germany or Liaoning, China. Such deposits possess clear taphonomic biases toward small-bodied animals, limiting our knowledge regarding feather presence in larger members of feathered clades. We present direct…

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.
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.
CZY TYRANOZAUR MIAŁ SKRZYDŁA? PIÓRA U NIEPTASICH DINOZAURÓW
TLDR
Structures potentialy homologous to feathers could also have developed in ornithischian dinosaurs, and even in pterosaurs, and in order to confirm or exclude it, one should still wait for further discoveries and research.
The Extent of the Preserved Feathers on the Four-Winged Dinosaur Microraptor gui under Ultraviolet Light
TLDR
Examination of the Microraptor gui specimen under ultraviolet light reveals that these feathers actually reach the body of the animal and were not disassociated from the bones, and that their arrangement and orientation is likely correct.
NEW OCCURRENCES OF FOSSILIZED FEATHERS: SYSTEMATICS, TAPHONOMY, AND PALEOECOLOGY OF THE SANTANA FORMATION OF THE ARARIPE BASIN (CRETACEOUS), NE, BRAZIL
TLDR
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.
New occurrences of fossilized feathers: systematics and taphonomy of the Santana Formation of the Araripe Basin (Cretaceous), NE, Brazil
TLDR
Feathered non-avian dinosaurs have not yet been described from the Crato Member, even though there are suggestions of their presence in nearby basins, and it is revealed that, despite the small sample size, they can be referred to coelurosaurian theropods.
A densely feathered ornithomimid (Dinosauria: Theropoda) from the Upper Cretaceous Dinosaur Park Formation, Alberta, Canada
From baby birds to feathered dinosaurs: incipient wings and the evolution of flight
TLDR
These findings provide a quantitative, biologically relevant bracket for theropod performance and suggest that protowings could have provided useful aerodynamic function early in maniraptoran history, with improvements in aerodynamic performance attending the evolution of larger wings, more effective feathers, and faster angular velocities.
Osteology of Khaan mckennai (Oviraptorosauria: Theropoda)
TLDR
The primary goal of this paper is to provide a relatively comprehensive descriptive morphology and illustrations for one member of Oviraptoridae, namely Khaan mckennai, with an emphasis on characters that can be used to establish a phylogenetic hypothesis for the taxon and group as a whole.
A bizarre, humped Carcharodontosauria (Theropoda) from the Lower Cretaceous of Spain
TLDR
An almost complete and exquisitely preserved skeleton of a medium-sized theropod from the Lower Cretaceous series (Barremian stage) Konservat-Lagerstätte of Las Hoyas in Cuenca, Spain is described and it is proposed that Concavenator has integumentary follicular structures inserted on the ulna, as in modern birds.

Basal tyrannosauroids from China and evidence for protofeathers in tyrannosauroids
TLDR
A new basal tyrannosauroid from the Early Cretaceous Yixian Formation of western Liaoning, China, which is small and gracile and has relatively long arms with three-fingered hands and provides the first direct fossil evidence that Tyrannosauroids had protofeathers.
The theropod ancestry of birds: new evidence from the late cretaceous of madagascar
TLDR
Rahona has a robust, hyperextendible second digit on the hind foot that terminates in a sicklelike claw, a unique characteristic of the theropod groups Troodontidae and Dromaeosauridae.
Four-winged dinosaurs from China
TLDR
New evidence is provided suggesting that basal dromaeosaurid dinosaurs were four-winged animals and probably could glide, representing an intermediate stage towards the active, flapping-flight stage of proavians.

TLDR
WAIR provides insight from behaviors observable in living birds into the possible role of incipient wings in feathered theropod dinosaurs and offers a previously unstudied explanation for the evolution of avian flight.
