基金项目:We thank Dr. Dale Winkler (Southern Methodist University, Dallas, TX, USA) for providing careful comments on the earlier version of the MS. Mr. Zhang Yuqing (Institute of Geology, Chinese Academy of Geological Sciences) prepared the specimen. This study was supported by the National Natural Science Foundation of China (No. 41272022) and the Central Public-interest Scientific Institution Basal Research Fund for the Chinese Academy of Geological Sciences (No. JB1504) to Junchang Lü.
中文摘要:Pangupterus liui gen. et sp. nov. from the Jiufotang Formation of Sihedang, Lingyuan City, Liaoning Province is erected based on a nearly complete lower jaw. It is characterized by having a total of 36 slender curved teeth with sharp tips, forming a distinct fish-grabbing mechanism; the teeth are well-spaced and are circular in section; the length ratio of the mandibular symphysis to the whole jaw is 20%; and the ratio of the tooth root width to tooth length is 12%. Toothed pterosaurs make up about 56.3% of the pterosaur assemblage from the Jiufotang Formation, which indicates that toothed forms played a key role in the ecosystem.
