Abstract
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.
