我们立刻看出?是一种奇异的素食动物，既不是哺乳类，也不是爬行类，叫作横齿龙（属于犬齿龙类） 。 |
| 3. | Brachiosaurus very obvious characteristics of the ordinary dinosaur foreleg mostly short , the type of dinosaur brachiosaurus foreleg on longer ; particularly their long neck
腕龙类的特徵极为明显，普通恐龙的前脚大多较短，腕龙类的恐龙前脚就较长； ?们的颈部尤其长。 |
| 4. | 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
摘要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。 |
| 5. | Experts are still unsure about the ancestry of pterosaurs . they are currently classified as belonging to a group of reptiles known as archosaurs , which include crocodiles , dinosaurs and birds
专家学者对于翼龙究竟如何演进而来仍然没有定论。 ?们目前被分类归在祖龙类，这一种爬虫类包括鳄鱼、恐龙和鸟类。 |
| 6. | Dromaeosaruid theropods can be restricted in the unique family dromaeosauridae ; furthermore , this family may also be subdivided into two subfamilies dromaeosauridae and velociraptorinae
奔龙类自成一科，即奔龙科( dromaeosauridae ) ，它又可进一步分为奔龙亚科( dromaeosaurinae )与疾走龙亚科( velociraptorinae ) 。 |
| 7. | This new specimen ( ngmc 00 - 12 - a ) is preserved not only by almost complete skeleton but also by many feathers . it is a quite small dromaeosaurid with the total length nearly 1 meter from the snout to the tip of the tail
这件奔龙类标本( ngmc00 - 12 - a )保存极为完整，全长(头骨吻端至尾巴末端)约1m ，是一个体较小的奔龙类。 |
| 8. | But the interrelationships among these genera remain uncertain until now . a great quantity of features recognized in dromaeosaurids supports the view that dromaeosauridae is the sister group of avialae
目前关于奔龙类在手盗龙类中的系统位置有几种不同的观点，本文支持奔龙类与avialae的关系最为密切的观点，即奔龙类是与avialae最为亲近的类群，两者构成姐妹群关系。 |
| 9. | The cladogram proposed in the present paper also suggests that the maniraptoran troodontidae and ovkaptoridae should have the branched feathers , and that feathers evolve and initially diversify in terrestrial theropod dinosaurs before the origin of birds and their flight

| 10. | 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 effects 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
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。 |
