对山东蒙阴盆地三台组以前及新发现的三趾型恐龙足迹化石开展了综合研究,认为应归入翘脚龙足迹属Grallator,其造迹者是小型兽脚类恐龙而非此前认为的鸟脚类恐龙,是目前山东省时代最老的恐龙足迹化石,也是中晚侏罗世恐龙活动的唯一证据。
對山東矇陰盆地三檯組以前及新髮現的三趾型恐龍足跡化石開展瞭綜閤研究,認為應歸入翹腳龍足跡屬Grallator,其造跡者是小型獸腳類恐龍而非此前認為的鳥腳類恐龍,是目前山東省時代最老的恐龍足跡化石,也是中晚侏囉世恐龍活動的唯一證據。

New revealed and previously reported dinosaur tracks,which are all from Middle-Upper Juras-sic Santai Formation of the Mengyin basin in Yangzhuang,Xintai City,Shandong Province,are syntheti-cally studied herein.These tracks are all tridactyl,longer than wide (ranges 12.0~17.5 cm in length and 9.5~12.4 cm in width),and the track length/width ratios range between 1.3 and 1.4.One of the track (LR-XT10.1)even shows clear sharp claw traces.All these features demonstrate that these traces are of theropod,instead of ornithopod as previously interpreted,dinosaur affinity,and they are herein tentatively labeled as Grallator isp.The tracks from the Santai Formation are the earliest dinosaur record ever repor-ted in Shandong Province,it also indicate that small-scale theropod dinosaurs once existed in the Megnyin basin during Middle-Late Jurassic time.
