尽管新疆地域辽阔,但其四足动物足迹在不久前仍是寥寥。近几年,这种情况得以改变,来自侏罗纪和白垩纪的四足动物足迹陆续被报道和描述,其形态可归入鸟类、非鸟恐龙和翼龙足迹。这里报道了中国科学院南京地质古生物研究所保存的新疆下侏罗统地层发现的第一个恐龙足迹。该足迹是一个小型兽脚类足迹,也是中国西北目前已知的最古老的恐龙足迹。标本暂时归入似张北足迹未定种(cf.Changpeipus isp.),它类似于常见的跷脚龙-实雷龙足迹丛(Grallator-Eubrontes plexus),该种类的足迹主宰着早、中侏罗世的中国,乃至全球之四足动物足迹群。
Despite the vast territory of Xinjiang, but its four-footed animal footprint in recent years is still very small. In recent years, this has changed. Footprints of quadrupedal animals from the Jurassic and Cretaceous have been reported and described one after another, and their morphology can be classified as birds, non-bird dinosaurs and pterosaurs. Here is the first dinosaur footprint discovered in the Lower Jurassic strata preserved by the Institute of Geology and Palaeontology, Chinese Academy of Sciences. The footprint is a small footprint footsteps and is also the oldest known dinosaur footprint in Northwest China. Specimens are temporarily classified as cf. Zhangpeipus isp., Which is similar to the common Grallator-Eubrontes plexus, whose footprints dominate early and Middle Jurassic World of China, and even the world’s four footprinting group.
