| 中文摘要:本文报道了浙江东阳发现的中国第2个翼龙足迹化石点, 也是亚洲发现的第8个翼龙足迹化石点。化石足迹产于晚白垩世早期方岩组的紫红色泥质粉砂岩中。发现有3个手的印迹和1个右足印。手的印迹的长宽分别为6.5 cm 和4cm. 非对称具有3个指的印迹。足迹9 cm长和1.5 cm宽。该足迹不同于以前发现的, 可能代表一新的类型。除了翼龙足迹外, 还发现鸟类、小型兽脚类、鸟脚类及蜥脚类脚印, 形成一个丰富的动物群, 它的发现为研究该地区的古生态环境及古地理具有重要意义。同时为以后在该地区发现这些造迹动物的骨骼化石提供了重要依据。 |

| New Pterosaur Tracks from the Early Late Cretaceous of Dongyang City, Zhejiang Province, China |

| Abstract:Compared with the osteological record, pterosaur footprints (tracks) are relatively rare. Herein we report on a new pterosaur footprint site from the Fangyan Formation of Dongyang City, Zhejiang Province, China. The sediments are composed of brown-red pelitic siltstones (Fig. 1) and the footprint bed is nearly horizontal. Initially, the Fangyan Formation was assigned to the late Lower Cretaceous (Bureau of Geology and Mineral Resources of Zhejiang Province, 1989), but more recently it has been redated as early Upper Cretaceous (Yu and Xu, 1999; Cai and Yu, 2001). This is the second pterosaur footprint side found in China so far, and it is also the eighth pterosaur footprint site from Asia. Among them, four are from Korea (Lockley et al., 1997; Hwang et al., 2002; Kim et al., 2006; Lee et al., 2008), two from Japan (Fujita, 2008; Lee et al., 2010) and one from China (Li et al., 2006; Zhang et al., 2006). |
