摘要
A new pterosaur ichnotaxon,Pteraichnus dongyangensis inchnosp.nov.,is proposed for the discovery of four pterosaur tracks from the Jinhua Formation of Dongyang City,Zhejiang Province of China.It is characterized by manus imprints with 29 ° of divarication of digits Ⅱ and Ⅲ and that of the digits Ⅰ and Ⅱ is 52°.Ratio of width to length of the pes imprint is 0.17.With pterosaur,sauropod,theropod and ornithopod footprints,webbed and non-webbed bird footprints are also found from the same quarry.These footprints will provide important evidence for the study of the paleoenvironments and the discovery of the bone ele ments of these footprint-makers,especially the pterosaur skeletons in the near future.
