: We describe a new species of Early Cretaceous bird from the Yixian Formation of Liaoning Province. Xinghaiornis lini gen. et sp. nov. is relatively large and characterized by a long, toothless rostrum and an elevated pedal digit I. The design of the skull and feet suggests that this bird was likely a mud-prober. This discovery provides strong support indicating that this avian trophic specialization originated at least 125 million years ago.

: On the basis of the taphonomy, osteological anatomy and ontogenetic variation, Zhuchengosaurus maximus Zhao et al., 2007 is considered to be synonymic with Shantungosaurus giganteus Hu, 1973 herein. This paper also deals with the life behavior of S. giganteus and the environment in which S. giganteus lived. S. giganteus is considered to be a terrestrial and gregarious herbivorous dinosaur and lived in hills and intervales in warm weather with plentiful rain and flourishing vegetation.

The pterosaur from the Yixian Formation in Beipiao, Liaoning Province, is characterized by the medium–sized individual, short tail, presence of the gastralia, strong forelimbs, radius and ulna longer than wing–metacarpal, extremely narrow and elongate metatarsals, degenerated and small phalanx V of hindlimb and so on. It must be a new genus and species, Eosipterus yangi gen. et sp. nov., in the early groups of the Suborder Pterodactyloidea. This is the first record of pterosaurs found in Liaonin...

Abstract A new hadrosauroid dinosaur, Shuangmiaosaurus gilmorei gen. et sp. nov., is described based on a complete left maxilla with articulated premaxilla and lacrimal fragments, and a complete left dentary from the mid-Cretaceous Sunjiawan Formation of Beipiao, Liaoning, northeastern China. Cladistic analysis shows that Shuangmiaosaurus is a basal hadrosauroid, and comprises the sister taxon to Hadrosauridae. In both Shuangmiaosaurus and Hadrosauridae, the maxilla-jugal suture is butt-jointed,...

Abstract Mesozoic remains of embryonic and early juvenile birds are rare. To date, a handful of in ovo embryos and early juveniles of enantiornithines from the Early Cretaceous of China and Spain and the Late Cretaceous of Mongolia and Argentina have comprised the entire published record of perinatal ontogenetic stages of Mesozoic birds. We report on the skeletal morphology of three nearly complete early juvenile avians from the renowned Early Cretaceous Yixian Formation of Liaoning Province in ...

Gansus yumenensis is the first Mesozoic bird found in China. It was collected from the Xiagou Formation in northwestern Gansu, which is considered to be equivalent to the Early Cretaceous strata yielding the Jehol biota in western Liaoning. Based on some characters such as elongated phalanges and short claws with pointed flexor tubercles, Gansus yumenensis is regarded as the bird adapted to life in the aquatic environment. Gansus yumenensis was originally erected only based on a unique specimen ...

We report on the discovery of an Early Cretaceous bird from northwestern Gansu Province, in northwestern China. Represented by a nearly complete left wing and shoulder girdle the size of a rock dove, the new bird was quarried from laminated yellowish mudstones of the Xiagou Formation (Xinminpu Group) near Changma, in the Jiuquan area. These deposits have previously yielded the only known specimen of Gansus yumenensis, a basal ornithuromorph represented by the distal half of a hind limb with long...

Abstract New specimens of the diminutive theropod dinosaur Microraptor zhaoianus are described. These specimens preserve significant morphological details that are not present or are poorly preserved in the holotype specimen, including aspects of the manus, pectoral girdle, dorsal vertebrae, ilium, and sacrum. These specimens were coded into a current matrix of theropod morphological characters. Microraptor is found to be the sister taxon to other dromaeosaurs. Dromaeosaurids are monophyletic an...

The lacustrine deposits of the Yixian Formation, western Liaoning, China, are renowned for producing remarkable vertebrate fossils, including primitive birds (e.g., Hou et al., 1995) and feathered dinosaurs (e.g., Ji et al., 1998). However, the first tetrapod described from these beds was a small reptile, Monjurosuchus Endo, 1940, whose relationships have remained problematic because key features of its morphology have been poorly understood. The discovery of five finely-preserved Monjurosuchus ...
