An oviraptorid dinosaur Huanansaurus ganzhouensis, belonging to the derived oviraptorid dinosaur, was discovered from the Late Cretaceous deposits in Ganzhou, Jiangxi Province. Its unique skull characteristics provide a new insight into the craniofacial evolution of oviraptorosaurid dinosaurs, paleogeographical distribution and paleoecological environments. Zhenyuanlong suni from the Early Cretaceous Yixian Formation of western part of Liaoning Province is a large, short-armed, winged dromaeosaurid dinosaur. It provides the evidence of feather morphologies and distribution in a short-armed dromaeosaurid dinosaur. The discovery of Zhenyuanlong also provides important evidence for the study of the diversity, the origin of feathers and the flight of Liaoning dromaeosaurid dinosaurs. Orientognathus chaoyngensis is the first Late Jurassic pterosaur discovered in western Liaoning and it is the largest rhamphorhynchinae pterosaur. The discovery of Orientognathus not only fills the temporal gap between the Middle Jurassic and Early Cretaceous pterosaur faunas of China but also plays an important role in the understanding of radiation evolution of rhamphorhynchids from the Late Jurassic. The above-mentioned important discoveries play a key role in our understanding of the hot and difficult issues such as the evolution of oviraptorid dinosaurs, the feather evolution in dromaeosaurid dinosaurs and the origin of bird feathers. In particular, the Ganzhou Dinosaurian Fauna is named based on the discovery of Huanansaurus.

A Late Cretaceous mammalian dentary from the Ashizawa Formation (Futaba Group), Fukushima, northeastern Japan.
Island Arc (advance online publication)
A mammalian dentary discovered in the Coniacian Ashizawa Formation (Fukushima, northeastern Japan) is described. The specimen is a fragment of the horizontal ramus of a left edentulous dentary with five alveoli, the distal four of which are plugged with broken roots. Based on the morphologies of the dentary and the roots, it is considered to be of a therian mammal. This constitutes the first discovery of a Mesozoic mammal in northeastern Japan and highlights the potential for future mammal discoveries in the Cretaceous System in northeastern Japan, which will be significant for disclosure of the mammalian faunal evolution in East Asia during the Late Cretaceous.

A possible Pararcus diepenbroeki vertebra from the Vossenveld Formation (Triassic, Anisian), Winterswijk, the Netherlands.
Netherlands Journal of Geosciences (advance online publication)
An isolated, completely ossified vertebra tentatively ascribed to the non-cyamodontid placodont Pararcus diepenbroeki is described from the Anisian Vossenveld Formation in Winterswijk, the Netherlands, and compared to other material from the same locality. This fossil is the first completely ossified vertebra of the taxon and most likely originates from an adult specimen. It was recovered c. 16 m deeper in the stratigraphy than previously described material of the species, which is thus far known only from Winterswijk. Based on the slanting angle of the transverse process, the vertebra is interpreted to originate from the dorsal region. Besides the overall agreements in morphology that warrant a tentative identification as Pararcus diepenbroeki, the newly described vertebra deviates from other known Pararcus vertebrae in the presence of a longer, well-ossified neural spine and a strongly constricted, less pachyostotic and ovaloid vertebral centrum. General agreement in morphology with previously described vertebrae suggests this novel condition indicates a different anatomical position and perhaps a varied ossification pattern.
