New discovery of the Jurassic dinosaur tracks from Bijie, Guizhou Province

From 2019 to 2020, the author found two dinosaur tracksites in Yuanbaoqing and Yejia Tian, Qixingguan District, Dafang County, Bijie City, Guizhou Province.The tracks of Yuanbaoqing were found at the bottom of Maanshan member of Ziliujing Formation, and they were reassigned to the basal ornithischian Anomoepus and medium sauropod, among which the Anomoepus were recorded for the first time in the Lower Jurassic of Sichuan Basin.The tracks of Yejiatian were found in the Upper Shaximiao Formation.They are assigned to large sauropod tracks which may have a potential relationship with large sauropods such as Mamenchisaurus that flourished in the area.This discovery is helpful for us to better understand the composition of the early and middle Jurassic vertebrate fauna in the south margin of the Sichuan Basin.
