摘要
根据中国浙江东阳上白垩统金华组发现的4个翼龙足迹,建立翼龙一新的遗迹种:东阳翼龙足迹。它具有以下特征:手迹的第Ⅱ和第Ⅲ指夹角为29°,第Ⅰ指和第Ⅱ指的夹角为52°;足迹的长与宽的比率为0.17,除了翼龙足迹外,在同一层位中还发现有蜥脚类、鸟脚类、兽脚类、帯蹼和不具蹼的鸟类足迹。这些足迹化石的发现,为研究该地区的古生态环境及以后动物的骨骼化石,尤其是翼龙骨骼化石提供了重要依据。
A new pterosaur ichnotaxon, Pteraichnus dongyangensis inchnosp, nov., is proposed for the discovery of four pterosaur tracl^s from the Jinhua Formation of Dongyang City, Zhejiang Province of China. It is characterized by manus imprints with 29~ of divarication of digits 11 and 111 and that of the digits I and I1 is 52~. Ratio of width to length of the pes imprint is 0.17. With pterosaur, sauropod, theropod and omithopod 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.
