A new enantiornithine birdLongipteryx chaoyangensis gen. et sp. nov. is described from the Early Cretaceous Jiufotang Formation in Chaoyang, western Liaoning Province. This new bird is distinguishable from other known enantiornithines in having uncinate processes in ribs, elongate jaws, relatively long wings and short hindlimbs, and metatarsal IV longer than metatarsals II and III. This new bird had probably possessed (i) modern bird-like thorax which provides firm attachment for muscles and… 
A new enantiornithine (Aves: Ornithothoraces) with completely fused premaxillae from the Early Cretaceous of China
We report a new small enantiornithine, Shangyang graciles gen. et sp. nov., based on a nearly complete and articulated skeleton from the Lower Cretaceous Jiufotang Formation of Liaoning Province,
The evolutionary and functional implications of the unusual quadrate of Longipteryx chaoyangensis (Avialae: Enantiornithes) from the Cretaceous Jehol Biota of China
TLDR
Describing the morphology of the quadrate in the unusually elongate skull of the Cretaceous enantiornithine bird Longipteryx chaoyangensis could greatly impact the study of several different aspects of bird biology including assessment of phylogenetic relationships, interpretation of the function and kinematics of the skull, reconstruction of foraging paleoecology, and evolution of skull morphological diversity among Mesozoic birds.
A New Enantiornitine Bird with Four Long Rectrices from the Early Cretaceous of Northern Hebei, China
TLDR
This is the first record of Mesozoic birds in having four long rectrices, which may represent morphologically a secondary sexual character, an intermediate stage from elongated scale to branched feather, and possess functional advantage in supplementing the lifting surface to compensate the unskilled flight.
A NEW SPECIES OF THE BASAL BIRD SAPEORNIS FROM THE EARLY CRETACEOUS OF LIAONING, CHINA
TLDR
The discovery of a new species of Sapeornis provides more tomical information about this basal avian, and documents the trend of size increase and some morpho- logical specializations in its evolutionary history, and adds to the understanding of the differentiation and diversity of birds in the Early Cretaceous terrestrial ecosystem.
A new Lower Cretaceous bird from China and tooth reduction in early avian evolution
TLDR
Phylogenetic analysis indicates that Zhongjianornis is phylogenetically basal to Confuciusornis and the dominant Mesozoic avian groups, Enantiornithes and Ornithurae, and therefore provides significant new information regarding the diversification of birds in the Early Cretaceous.
A New Enantiornithine Bird from the Lower Cretaceous of Western Liaoning, China, and Its Implications for Early Avian Evolution
TLDR
A new enantiornithine bird from the Lower Cretaceous Jiufotang Formation of western Liaoning, China is described, indicating that a carpometacarpal morphology similar to that seen in modern birds probably evolved independently in enantiornsithines and appeared earlier than in Ornithuromorpha, and demonstrates that character evolution in early birds was more complex than previously believed.
Largest bird from the Early Cretaceous and its implications for the earliest avian ecological diversification
TLDR
A new bird from the Early Cretaceous feathered-dinosaur-bearing continental deposits of Liaoning, northeast China is reported, which is not only larger than Archaeopteryx but is nearly twice as large as the basal dromaeosaur Microraptor.
The First Enantiornithine Bird from the Upper Cretaceous of China
TLDR
Histological study shows that the bones of Parvavis were composed of parallelfibered bone tissue without lines of arrested growth, and indicated that growth rate had slowed but had not stopped at any stage prior to death, and the new bird was probably close to adult body size at the time of death.
A New Specimen of Large-Bodied Basal Enantiornithine Bohaiornis from the Early Cretaceous of China and the Inference of Feeding Ecology in Mesozoic Birds
TLDR
It is hypothesized that cranial morphology as well as the number and shape of the preserved stones in Bohaiornis may be most consistent with a raptorial ecology previously unknown for Enantiornithes and considered rare for Avialae.

TLDR
Modern avian flight function and perching capability must have evolved in small-bodied birds in inland habitats not long after Archaeopteryx.

Cursoriality in bipedal archosaurs
TLDR
Surprisingly, Caudipteryx, described as a theropod dinosaur, possessed an anterior centre of mass and hindlimb proportions resembling those of cursorial birds, which may have implications for interpreting the locomotory status of its ancestors.
