    山东蒙阴盆地侏罗纪恐龙和翼龙足迹的新发现

    New discovery of dinosaur and pterosaur tracks in Jurassic strata on the Mengyin Basin, Shandong Province

    • 摘要: 山东的恐龙骨骼与足迹记录主要集中在白垩纪,侏罗纪恐龙则较为稀少。在中国东部山东省新泰市杨庄附近中晚侏罗世三台组保存有三趾型兽脚类足迹和翼龙足迹,此次发现的翼龙足迹为山东省境内侏罗纪地层的首次记录。三趾型兽脚类恐龙足迹经鉴定后被归入Grallator isp.,翼龙足迹被归入Pteraichnus isp.,足迹整体保存状态有限,难以确定种。在三台组发现的三趾型兽脚类恐龙足迹和翼龙足迹,丰富了研究区的生物种类,对该地区古生态、物种的古地理分布等方面研究具有较为重要的意义。

       

      Abstract: Dinosaur skeletons and tracks recorded in Shandong province are mainly Cretaceous, while those from Jurassic are relatively rare.This article describes the tracks of tridactyl theropods and pterosaur tracks preserved in the Middle-Upper Jurassic Santai Formation near Yangzhuang, Xintai City, Shandong Province, East China.The discoveries of pterosaur tracks are the first records of Jurassic strata in Shandong Province, among which the tridactyl theropod dinosaur tracks are assigned to Grallator isp.; and the Pterosaur tracks are assigned to Pteraichnus isp..However, the tracks are poorly preserved, so it is difficult to make any particular ichno-taxonomic analysis.The tridactyl theropod dinosaur and pterosaur tracks found in Santai Formation enrich the biological species in the research area and are of great significance to the paleoecology, paleogeography and paleoenvironment of this area.
