| 摘 要： | 根据发现于辽西朝阳九佛堂组一具有部分头骨的不完整骨架,命名一新的帆翼龙--赵氏龙城翼龙(新属新种).头骨和牙齿形态显示龙城翼龙与宽齿帆翼龙的关系要比与其他翼龙的关系密切,龙城翼龙是目前辽西九佛堂组中发现的唯一的帆翼龙类.帆翼龙科原仅一属种,发现于英国早白垩世地层中,辽西早白垩世新帆翼龙的发现,不但扩大了其地理分布,也证明辽西是晚侏罗世至早白垩世翼龙辐射、分异的重要地区.这对研究翼龙的起源和演化有重要意义.

| Abstract: | A new isfiodactyhd pterosaur, Longchengpterus zhaoi gen. et sp. nov., is erected, based on an incomplete skeleton with a part of skull from the Jiufotang Formation at Chaoyang, western Liaoning. The skull and tooth morphologies indicate that Longchengpterus zhaoi is more closely related to lstiodactylus latidens than to other pterosaurs. Longchengpterus zhaoi is the only istiodactyhd pterosaur from the Jiufotang Formation of western Liaoning. The family Isfiodactyhd originally had only a genus and species, which was found in the Early Cretaceous strata of Britain. The discovery of the new Early Cretaceous istiodactyhd from western Liaoning not only expands its geographical distribution but also proves that western Liaoning is an important region for the istiodactylid radiation and diversity during the Late Jurassic to Early Cretaceous. It has great implications for the study of the origin and evolution of pterosaurs. |
