The unusual presence of long pennaceous feathers on the feet of basal dromaeosaurid dinosaurs has recently been presented as strong evidence in support of the arboreal–gliding hypothesis for the origin of bird flight, but it could be a unique feature of dromaeosaurids and thus irrelevant to the theropod–bird transition. Here, we report a new eumaniraptoran theropod from China, with avian affinities, which also has long pennaceous feathers on its feet. This suggests that such morphology might… 
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 new Jurassic theropod from China documents a transitional step in the macrostructure of feathers
TLDR
The phylogenetic analysis places Serikornis, together with other Late Jurassic paravian from China, as a basal paravians, outside the Eumaniraptora clade, suggesting that hindlimb remiges evolved in ground-dwelling maniraptorans before being co-opted to an arboreal lifestyle or flight.
A new long‐tailed basal bird from the Lower Cretaceous of north‐eastern China
TLDR
A revision of long-tailed birds from China and a phylogenetic analysis of basal Avialae suggest that Jeholornithiformes were paraphyletic, with Jixiangornis orientalis being the sister-taxon of pygostylia.
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.
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.
PISCIVORY IN THE FEATHERED DINOSAUR MICRORAPTOR

  • Environmental Science, Geography
    Evolution; international journal of organic evolution
  • 2013
TLDR
The largest specimen of the four‐winged dromaeosaurid dinosaur Microraptor gui includes preserved gut contents, which offer unique insights into the ecology of nonavian dinosaurs early in the evolution of flight.
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.
A new raptorial dinosaur with exceptionally long feathering provides insights into dromaeosaurid flight performance.
TLDR
It is demonstrated how the low-aspect-ratio tail of the new fossil would have acted as a pitch control structure reducing descent speed and thus playing a key role in landing and insight into the flight performance of microraptorines is provided.

A preliminary account of a new tyrannosauroid theropod from the Wessex Formation (Early Cretaceous) of southern England
TLDR
It is concluded that the new genus and species of coelurosaurian theropod dinosaur from the Wessex Formation of the Isle of Wight is one of the earliest and (with the exception of some teeth and an isolated ilium from Portugal) the first from Europe.
A juvenile coelurosaurian theropod from China indicates arboreal habits
TLDR
It is suggested that the initial appearance of tree-adaptation in theropods was probably not directly related to flight but to other functions, such as seeking food or escaping from predators.
The smallest known non-avian theropod dinosaur
TLDR
This is the first mature non-avian dinosaur to be found that is smaller than Archaeopteryx, and it eliminates the size disparity between the earliest birds and their closest non-Avian theropod relatives.
A NEW SALAMANDER (AMPHIBIA: CAUDATA) FROM THE EARLY CRETACEOUS JEHOL BIOTA
TLDR
The discovery of Jeholotriton documents the third Mesozoic salamander from China and differs from other early caudates in having an anteromedially directed ramus of pterygoid that connects to the skull table rather than the maxilla.
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.
Small pterosaurs and dinosaurs from the Uncompahgre fauna (Brushy Basin Member, Morrison Formation: ?Tithonian), Late Jurassic, western Colorado
Small vertebrates were recovered from the matrix encasing specimens of giant sauropod dinosaurs (Supersaurus, Ultrasaurus, Dystylosaurus) collected from the “Dry Mesa” Quarry (Brushy Basin Member,
Deinonychosaurian Fossils from the Jehol Group and the Coelurosaurian Evolution
TLDR
An evolutionary model for feather evolution is proposed and the evolutionary trend within the Coelurosauria is discussed and particularly those features related to the origin of avian flight.
A nearly completely articulated rhamphorhynchoid pterosaur with exceptionally well-preserved wing membranes and “hairs” from Inner Mongolia, northeast China
TLDR
The “hair” of Jeholopterus bears some resemblance to the hair-like integumental structures of the feathered dinosaur Sinosauropteryx although there is yet no direct evidence to argue for or against their homology.
Earliest known crown-group salamanders
TLDR
The discovery of well-preserved Middle Jurassic salamander from China constitutes the earliest known record of crown-group urodeles (living salamanders and their closest relatives) and provides evidence to support the hypothesis that the divergence of the Cryptobranchidae from the Hynobiidae had taken place in Asia before the Middle Jurassic period.
