Recent fossil discoveries have substantially reduced the morphological gap between non-avian and avian dinosaurs, yet avians including Archaeopteryx differ from non-avian theropods in their limb proportions. In particular, avians have proportionally longer and more robust forelimbs that are capable of supporting a large aerodynamic surface. Here we report on a new maniraptoran dinosaur, Anchiornis huxleyi gen. et sp. nov., based on a specimen collected from lacustrine deposits of uncertain age… 

Figures and Tables from this paper

A new Jurassic scansoriopterygid and the loss of membranous wings in theropod dinosaurs
TLDR
Support is provided for the widespread existence of membranous wings and the styliform element in the Scansoriopterygidae, as well as evidence for the diet of this enigmatic theropod clade.
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.
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.
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.
Description and ontogenetic assessment of a new Jehol microraptorine
TLDR
It is confirmed that this microraptorine theropod was around a single year in age and still growing at death, but that the growth had slowed, which indicates that presence of a variety of feather types, including filamentous feathers, pennaceous primaries, and long rectrices, likely used for ornamentation, preceded skeletal maturity and full adult size.
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.
The first specimen of Archaeopteryx from the Upper Jurassic Mörnsheim Formation of Germany
TLDR
It is shown, using the first synchrotron microtomographic examination of the genus, that the eighth or Daiting specimen of Archaeopteryx possesses a character suite that robustly constrains it as a basal avialan (primitive bird), which is distinctive enough to merit designation as a new species.
Paravian Phylogeny and the Dinosaur-Bird Transition: An Overview
TLDR
It is concluded that troodontid affinities of anchiornithines, and dromaeosaurids affinITIES of microraptorians and unenlagiids are dismissed in favor of sister group relationships with Avialae, and main phylogenetic hypotheses that compete some topics about the non-avian dinosaur-bird transition are analyzed.
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.

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.
Limb proportions and avian terrestrial locomotion
TLDR
It is concluded that birds (Archaeopteryx + crownclade Aves) are a subgroup of the theropod dinosaurs and feathers cannot be used to define birds, as is traditionally advocated.
Anatomy of the primitive bird Sapeornis chaoyangensis from the Early Cretaceous of Liaoning, China
Two new, nearly completely articulated skeletons of Sapeornis chaoyangensis provide much new information about the anatomy of this basal avian, particularly in the skull, pectoral girdle, forelimb,
The earliest dromaeosaurid theropod from South America
TLDR
A near-complete, small dromaeosaurid is described that is both the most complete and the earliest member of the Maniraptora from South America and which provides new evidence for a unique Gondwanan lineage of DromaeOSauridae with an origin predating the separation between northern and southern landmasses.
A Basal Dromaeosaurid and Size Evolution Preceding Avian Flight
TLDR
Change in theropod body size leading to flight's origin was not unidirectional, and the two dinosaurian lineages most closely related to birds, dromaeosaurids and troodontids, underwent four independent events of gigantism, and in some lineages size increased by nearly three orders of magnitude.
