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.
A new feathered maniraptoran dinosaur fossil that fills a morphological gap in avian origin
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…

It is concluded that dinosaurs did not experience a progressive decline at the end of the Cretaceous, nor was their evolution driven directly by the KTR, and major diversification shifts occurred largely in the first one-third of the group's history.

The Daohugou Biota and the Jehol Biota are two successive Lagerstätte assemblages that collectively offer a taphonomically consistent window into the Mesozoic life of northeast Asia over a significant span of geologic time.

Zhanghenglong is probably a relatively derived non-hadrosaurid hadrosauroid, based on the inferences made from the morphological comparisons, quantitative evaluation of measurements, and cladistic analysis.

Although the understanding of the mechanical properties of the wing membrane is hampered by the lack of knowledge regarding the composition of the actinofibrils, the configuration observed in Jeholopterus might have allowed subtle changes in the membrane tension during flight, resulting in more control of flight movements and the organization of the wings when the animal was at rest.
Pedal Claw Curvature in Birds, Lizards and Mesozoic Dinosaurs – Complicated Categories and Compensating for Mass-Specific and Phylogenetic Control

It is concluded that there is no strong mass-specific effect on claw curvature; furthermore, correlations between claw geometry and behaviour are consistent across disparate clades.
A new dromaeosaurid (Dinosauria: Theropoda) from the Upper Cretaceous Wulansuhai Formation of Inner Mongolia, China

A number of cranial and dental features seen in L. exquisitus and T. mangas suggest that these two taxa are probably intermediate in systematic position between known basal and derived dromaeosaurids, and the discovery of Linheraptor exquis Titus is thus important for understanding the evolution of some salient feature seen in the derived dronaeosaurusids.

The Extent of the Preserved Feathers on the Four-Winged Dinosaur Microraptor gui under Ultraviolet Light
- D. Hone, H. Tischlinger, Xing（徐星） Xu, Fucheng Zhang
- BiologyPLoS ONE
- 15 February 2010
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.
