中国新沂马陵山白垩纪恐龙足迹——从虎到肉食龙及由传说至古生物学

    Cretaceous dinosaur tracks from Maling Mountain of Xinyi City, Jiangsu Province:From tiger to carnivorous dinosaur and from folklore to paleontology

    • 摘要: 江苏省新沂市马陵山地区的4个神秘的印记,传统上被解释为“李存孝打虎处”的“虎爪印”和“人足迹”,重新将其解释为大盛群田家楼组恐龙足迹。这些足迹中只有一个最深的“虎爪印”保存了可识别的趾印,表明它是一个有着后内侧拇趾印的兽脚类恐龙左足迹,是一道单步约50cm的直线行迹的一部分;另一种解释是该足迹为小型蜥脚类恐龙的右后足迹,形成行迹的右侧部分,其左侧部分没有保存。马陵山足迹点提供了恐龙足迹如何影响中国民间传说的另一个案例。

       

      Abstract: Four enigmatic depressions, traditionally referred to as "tiger's paw traces" and "human footprints" from "Li Cunxiao Fighting Tiger" site of the Maling Mountain area in Xinyi City of Jiangsu Province are here interpreted as dinosaur tracks belonging to the Early Cretaceous Tianjialou Formation of the Dasheng Group. Only one of the "tiger's paw traces" at the largest depth preserves recognizable digit tracks, suggesting it is a left theropod track, with posterior medial hallux trace, forming part of a linear trackway with steps of~50cm. Alternatively, the track may be a small sauropod right pes track forming part of a trackway in which the left side footprints were not registered. Malingshan tracksite demonstrates another case of how dinosaur tracks influenced Chinese folklore.
