The smallest known non-avian theropod dinosaur
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.
Four-winged dinosaurs from China
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.
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.
A basal troodontid from the Early Cretaceous of China
The discovery of Sinovenator and the examination of character distributions along the maniraptoran lineage indicate that principal structural modifications toward avians were acquired in the early stages of manIRaptoran evolution.
The AME2016 atomic mass evaluation (II). Tables, graphs and references
This paper is the second part of the new evaluation of atomic masses, AME2016. Using least-squares adjustments to all evaluated and accepted experimental data, described in Part I, we derive tables
A basal ceratopsian with transitional features from the Late Jurassic of northwestern China
Character distributions along the marginocephalian lineage reveal that, compared to the bipedal Pachycephalosauria, the dominantly quadrupedal ceratopsians lost many marginocesphalian features and evolved their own characters early in their evolution.
Basal tyrannosauroids from China and evidence for protofeathers in tyrannosauroids
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.
A Jurassic ceratosaur from China helps clarify avian digital homologies
A new basal Ceratosaur from the Oxfordian stage of the Jurassic period of China is reported, representing the first known Asian ceratosaur and the only known beaked, herbivorous Jurassic theropod, and possesses a strongly reduced manual digit I, documenting a complex pattern of digital reduction within the Theropoda.
An unusual oviraptorosaurian dinosaur from China
Oviraptorosaurians are an unusual group of theropod dinosaurs, with highly specialized skulls. Here we report a new oviraptorosaurian, Incisivosaurus gauthieri, gen. et sp. nov., from the lowest part
