| 中文摘要:传统上讲，翼龙类分为两大类群，构成复系的基干类群和构成单系的进步类群。本文记述的一新达尔文翼龙，它与正型标本模块达尔文翼龙发现于同一地点，二者均产自中侏罗世的髫髻山组。但是与模块达尔文翼龙存在区别，可能代表达尔文翼龙一新种。新的标本完整，可为研究达尔文骨骼学提供更多信息。 在理解翼龙的演化，分布及生态学起着非常重要的作用。 |

| Abstract:Traditionally, pterosaurs are classified in two groups: a paraphyletic grade of basal forms (‘rhamphorhynchoids’) and the monophyletic, derived pterodactyloids (Wellnhofer 1991). Members of the basal group are characterized by a short skull, short neck with cervical ribs, short metacarpals and long tail while the derived group is characterized by a long skull, a long neck lacking cervical ribs, long metacarpals and short tails (with the exception of anurognathids – a clade of non-pterodactyloids with a pterodactyloid-like short tail). Pterodactyloids are thought to have evolved from rhamphorhynchoid pterosaurs (Wellenhofer 1991), but there was no fossil evidence to confirm the transition in skull and tail morphology between these two groups until the recent discovery of Darwinopterus modularis from the Middle Jurassic Tiaojishan Formation of Jianchang, western Liaoning in northeastern China (Lü et al. 2010). |
