本文详细描述了中国辽西热河群部分恐爪龙类化石的骨骼与皮肤衍生物形态。本研究：1) 提供了有关辽宁恐爪龙类最详细的骨骼学信息；2）提出了羽毛演化的一个新模型；3）综合地分析了虚骨龙类的系统关系；4）分析身体不同部位的信息对复原系统发育的影响及虚骨龙类各个演化阶段身体不同部位的相对演化程度；5）讨论了虚骨龙类的演化趋向，尤其是和飞行起源相关特征的变化。

The osteology and integument of deinonychosaurs from the Jehol Group of western Liaoning are studied and a parsimonious phylogenetic analysis of the interrelationships of coelurosaurian dinosaurs is performed. This study: (1) provides the most detailed osteological and integumentary descriptions on Liaoning deinonychosaurs; (2) proposes an evolutionary model for feather evolution; (3) analyzes the interrelationships of the Coelurosauria; (4) evaluates the affect of combining information from different parts of the body in reconstructing coelurosaurian evolution, and (5) discusses the evolutionary trend within the Coelurosauria and particularly those features related to the origin of avian flight.
