Lu et al., 2009. A preliminary report on the new dinosaurian fauna from the Cretaceous of the Ruyang Basin, Henan province of Central China. J. of the Pal. Soc. of Korea 25: 43-56

Abstract:
A new dinosaur fauna, the Ruyang Gigantic Sauropod Dinosaurian Fauna from the early Late Cretaceous of the Ruyang Basin is named. The new dinosaurian fauna is dominated by large-sized sauropod dinosaurs, companying with theropod dinosaurs, such as ornithomimid, oviraptorid, spinosaurid and carcharodontosaurid dinosaurs. Two new taxa are erected, they are a oviraptorid dinosaur Luoyanggia liudianensis gen. et sp. nov., and a sauropod Xianshanosaurus shijiagouensis gen et sp. nov. The dinosaur assemblage from the Ruyang Basin indicates that the dinosaur-bearing deposits are Cenomanian in age.

Etant donné que l'article a été publié en 2009, je vais retirer ces noms de la liste des dinosaures décrits en 2010.

Xu e Han, 2010. A new oviraptorid dinosaur (Theropoda: Oviraptorosauria) from the Upper Cretaceous of China. Vertebrata PalAsiatica 48: 11-18.

Abstract:
Here we report a new oviraptorid taxon based on a specimen possibly collected from the Upper Cretaceous Nanxiong Formation of Ganzhou, Jiangxi, China. This new taxon is distinguishable from other species based on the following features: a crest formed by the premaxillae and nasals having a step-wise posterior end and bearing two longitudinal grooves and numerous oblique striations on each of its lateral surfaces, an extremely elongate external naris that is posteriorly situated and close to the orbit, a deep fossa on the dorsal surface of the palatal ramus of the pterygoid, several longitudinal grooves along the posterior part of the dorsal margin of the dentary, and several tubercles along the lateral shelf at the dorsal margin of the surangular. This new taxon possesses some palatal and mandibular features not seen in other oviraptorids but similar to those in more basal oviraptorosaurs, suggesting a relatively basal position for this taxon within the Oviraptoridae. This systematic hypothesis is supported by a numerical cladistic analysis. This discovery not only adds to the known diversity of Late Cretaceous oviraptorids, but provides significant new information on the evolution of some oviraptorid features.
