中文摘要：

在江西赣州地区晚白垩世地层中发现的窃蛋龙类化石——赣州华南龙，属于进步窃蛋龙类，其独特的头部特征为研究窃蛋龙类恐龙的颅面演化、古地理分布及古生态环境提供重要信息；在辽西早白垩世义县组地层中发现的大型、前肢短的驰龙类恐龙——孙氏振元龙，为大型、短前肢类型的驰龙类提供羽毛形态学方面的重要信息，为研究驰龙类的多样性、鸟类羽毛以及飞行起源提供了重要依据；在辽西发现的喙嘴龙类翼龙——朝阳东方颌翼龙，是该地区晚侏罗世地层中发现的第一件翼龙标本，不仅填补了时代上的空白，同时对于印证晚侏罗世喙嘴龙类的辐射演化具有重要作用。这些重要发现对于研究窃蛋龙类的演化、驰龙类羽毛演化及鸟类羽毛起源等热点与难点问题提供了重要的参考依据，尤其在发现华南龙的基础上，命名了赣州恐龙动物群。

英文摘要：

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.
