摘要

摘要在热河生物群中，滤食性栉龙翼龙的生物多样性非常丰富。本文报道了辽西建昌早白垩世九佛塘组中发现的一具新的翼骨。该标本表现出唯一的自异形，第一翼指骨比第二翼短，比第三翼长。有趣的是，它显示出骨骼成熟与共骨化的元素，但它只有大约75%的未成熟的完整型。这种差异揭示了Forfexopterus的发育变异，但其与性别异形的关系需要更多可用的材料来确定。

A new wing skeleton of Forfexopterus (Pterosauria: Ctenochasmatidae) from the Early Cretaceous Jehol Biota reveals a developmental variation

Abstract. In the Jehol Biota, the filter-feeding ctenochasmatid pterosaurs flourished with a high biodiversity. Here, we report a new wing skeleton of the ctenochasmatid Forfexopterus from the Early Cretaceous Jiufotang Formation in Jianchang, western Liaoning, China. The specimen exhibits the sole autapomorphy, the first wing phalanx shorter than the second and longer than the third. Interestingly, it exhibits a skeletal maturity with co-ossified elements, but it is only about 75 % the size of the immature holotype. This discrepancy reveals developmental variation of Forfexopterus, but its relationship with sexual dimorphism needs to be certain by more available material.

期刊介绍： Fossil Record (FR) is the palaeontological journal of the Museum für Naturkunde Berlin. This journal was founded in 1998 under the name Mitteilungen aus dem Museum für Naturkunde Berlin, Geowissenschaftliche Reihe and appears with two issues each year. Fossil Record publishes original papers in all areas of palaeontology including the taxonomy and systematics of fossil organisms, biostratigraphy, palaeoecology, and evolution. All taxonomic groups are treated, including invertebrates, microfossils, plants, and vertebrates.
