摘要
通过系统地梳理以往研究成果,归纳总结了陕西省恐龙足迹化石的分布特征和科学价值。陕西省目前发现的恐龙足迹化石分布在11处地点,地层分布主要为中侏罗世延安组和早白垩世洛河组,已命名的恐龙足迹共有5属9种,造迹恐龙以兽脚类占绝对优势,个体普遍较小。陕西省恐龙足迹化石的发现和研究弥补了恐龙骨骼化石的匮乏,丰富了中国恐龙足迹化石种类,为不同地区相同沉积环境下地层对比提供了证据,表明造迹恐龙生活在季节性干旱-湿润气候交替的环境中。
The distribution characteristics and scientific values of dinosaur tracks in Shaanxi Province are summarized by systematically compling the previous research achievements.Altogether 11 dinosaur tracksites are discovered in Shaanxi Province,and the dinosaur-track-bearing formations mainly belong to the Middle Jurassic Yan an Formation and Early Cretaceous Luohe Formation.According to the dinosaur tracks in Shaanxi Province,5 ichnogenus and 9 ichnospecies are nominated,and the dinosaur trackmakers are mostly theropod with small size.Based on the study of dinosaur tracks,the lack of dinosaur skeleton fossils in Shaanxi Province are compensated,the ichnotaxa in China are enriched,the stratigraphic correlation in the same sedimentary environment between different regions are realized,and the dinosaurs trackmakers lived in an alternate climate of seasonal drought-humid environment are indicated.
