记述中国河北省赤城县倪家沟化石点一组恐龙行迹,并命名一新属新种---中国猛龙足迹(Menglon-gipus sinensisichnogen.et ichnosp.nov.)。足迹来自土城子组,位于侏罗-白垩纪界线。相邻的义县组曾发现最古老的恐爪龙类骨骼化石,而中国猛龙足迹的发现表明恐爪龙类早在义县组之前便出现在该地区。中国猛龙足迹的造迹者体长约65cm,非常接近于基干的近鸟类。此外,为四川伶盗龙足迹(Velociraptorichnus sichuanensis)的模式标本提供更多细节,并讨论驰龙类足迹型与其他兽脚类足迹之间的联系。
Describe a group of dinosaur tracks at the Nijiagou fossil site in Chicheng County, Hebei Province, China and name a new genus Menglon-gipus sinensisichnogen.et ichnosp.nov. Footprints from Tuchengzi group, located in the Jurassic - Cretaceous line. The neighboring Yixian Formation discovered the oldest claw-type fossil skeletons, while the discovery of the Chinese Raptor footprint showed that the claw-claw species appeared in the area as early as the Yixian Formation. The creator of the Chinese Raptors footprint is about 65cm in length, very close to the baskets of near birds. In addition, more detail is provided for the model specimens of the Velociraptorichnus sichuanensis and the linkages between the Chiron species and other orphan footprints are discussed.
