Abstract: In October 2020, five dinosaur tracks were discovered on the bedding plane of the siltstone of the Lower Cretaceous Cangxi Formation in Tongjiang County, the northern margin of Sichuan Basin.Their morphology is similar to the classic theropods tracks of Eubrontes(such as bipedal, a broad pes, functionally tridactyl with a relatively short digit Ⅲ).These tracks reveal that the medium to large-sized Eubrontes were widely distributed in the Lower Cretaceous of Sichuan Basin.This new discovery is of important significance to the paleoclimate, paleogeography and stratigraphic contrast of the northern margin of the Sichuan Basin.
