Abstract:  Although Xinjiang Uyghur Autonomous Region is a vast territory, its fossil tetropod track record is scant. In recent years, this situation has begun to change and a variety of Jurassic and Cretaceous tetrapod tracks have been reported and described from Xinjiang, including tracks attributable to birds, non-avian dinosaurs, and pterosaurs. Here we report on the first dinosaur track discovered from Lower Jurassic deposits in Xinjiang. The tracks are those of a small theropod and are oldest known dinosaur tracks in Northwest China. The tracks are provisionally assigned to cf. Changpeipus isp., which resembles well-known tracks in the Grallator-Eubrontes plexus, which dominate tetrapod ichnofaunas in the Early and Middle Jurassic both within China and globally.

摘要: 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。
