| 摘 要： | 在鄂尔多斯盆地东北缘神木市中鸡一带下白垩统洛河组上部紫红色薄层砂岩层面中,发现丰富的恐龙与其他四足类的足迹化石。这些足迹可分为3类,分别为三趾型兽脚类足迹(实雷龙足迹类),两趾型兽脚类足迹(恐爪龙类足迹)和小型四足类足迹(哺乳形类/兽孔类足迹)。此种组合在中国尚属首次发现,对古气候、古环境、古地理和地层对比都具有重要的意义。

| Abstract: | In September 2017, the authors found abundant dinosaur and other tetrapod tracks on thin-layer purple red sandstone of Lower Cretaceous Luohe Formation at the northeast border of Ordos Basin in Zhongji Town, Shenmu City. They can be divided into tridactyl theropod tracks (Eubrontidae), didactyl theropod tracks (deinonychosaurian tracks), and small tetrapod tracks (Mammaliamorpha/Therapsida tracks). Such assemblage has never been found in China before and is of great significance to researches on paleoclimate, palaeoenvironment, paleogeography and stratigraphic correlation. Their detailed classification will be further studied. |
