Dinosaur tracks from the Lower Cretaceous Xiguayuan Formation in the Luanping Basin, Hebei Province, China

The Qiaomaigoumen dinosaur tracksite was previously described briefly in 1995 and 2006 based on examination of a single surface (∼200 m2) with five trackways representing two quadrupedal ornithopods (Caririchnium isp.) and three bipedal theropods. While confirming this general description, this stud...

Description
Summary:The Qiaomaigoumen dinosaur tracksite was previously described briefly in 1995 and 2006 based on examination of a single surface (∼200 m2) with five trackways representing two quadrupedal ornithopods (Caririchnium isp.) and three bipedal theropods. While confirming this general description, this study also revealed that two additional sites (Sangyuan I and II) had been found, and that tracks from all three sites had been collected for local institutions. This created the opportunity to describe the ichnofauna more completely, including a variety of theropod morphotypes (cf. Jialingpus isp. and cf. Eubrontes isp.) not previously identified in this area. It is also inferred that the tracksites occur in the Xiguayuan Formation, not in the Jiufotang Formation as previously suggested. This indicates an equivalency with the Jehol Biota and some track elements corresponding generally to Jehol body fossils.
