    The First Discovery of the Early Cretaceous Pterosaur Track and Its Significance in Yanguoxia, Yongjing County, Gansu Province

    • 摘要: 甘肃永靖盐锅峡恐龙足迹1号化石点中保存有翼龙足迹, 该足迹是我国翼龙足迹的首次发现.翼龙足迹为四足行走, 行迹宽.前脚为不对称三趾型, 趾行式, 其中Ⅱ趾最短, Ⅳ趾最长, 足迹外偏, 偏角大, Ⅳ趾与行迹交角为160°~ 180°.后脚外形为近长方形, 四趾型, Ⅱ、Ⅲ趾较Ⅰ、Ⅳ趾长, 行式, 脚长为宽的3倍, 足迹外偏, 偏角30°.足迹特征表明该翼龙足迹属于一新种.沉积特征表明翼龙足迹产于湖岸环境.
