| 摘 要： | 记叙了中国陕西省商洛市邵涧村下白垩统东河群2个大型兽脚类恐龙足迹，并将其归于Megalosauripus isp.。
东河群的时代与热河生物群同期，邵涧Megalosauripus isp. 可能可与热河生物群的大型兽脚类恐龙之足部形态做简
单对比。此外，邵涧Megalosauripus isp.造迹者的体长约为7.4m，这意味着早白垩世的陕西中南部亦存在着大型的
兽脚类恐龙。邵涧Megalosauripus isp.的发现，不仅为中国早白垩世恐龙足迹增加了新的成员，而且为将来在该地
区下白垩统中发现大型兽脚类恐龙的骨骼化石提供了确凿的依据。

| Abstract: | Described herein are two large theropod tracks from the Lower Cretaceous Donghe Group in
Shaojian Village, Shangluo City, Shaanxi Province. The tracks are attributed to Megalosauripus isp.
The Donghe Group is contemporaneous with the Jehol Biota. Megalosauripus isp. at the Shaojian track
site can be compared with the foot structure of large theropods of the Jehol Biota. Furthermore, the
length of the track maker of Megalosauripus isp. is approximately 7.4 m, which suggests that large
theropods occurred in central-southern Shaanxi Province in the Lower Cretaceous. The discovery of
Megalosauripus isp. adds a new member to Lower Cretaceous dinosaur footprints in China, and also
indicates the very probable discovery of large-sized theropod dinosaur skeletons from the Lower
Cretaceous sediments of this area in the near future. |
