Abstract：Guizhou Province is rich in records of Mesozoic vertebrate fossils,mostly Triassic marine reptile fossils,while Jurassic and Cretaceous vertebrate fossils are scarce. There are nine Mesozoic tetrapod track sites discovered in Guizhou Province,which are Niuchang and Longchang sites from Zhenfeng,Yaopu site from Anshun,Fuchu site from Hezhang,Xiangshui sites I and II from Bijie,Maotai site from Renhuai,Baoyuan site from Chishui and Tongmin site from Xishui. This paper described more tracks of Longchang site from Zenfeng,and try to summarize the discovery and research history,track types and their characteristics,and the palaeoecological information reflected in all nine track sites. All these records consist of 69 trackways and 420 isolated tracks for a total of 991 tracks of tetrapod remains indicative of at least 477 trackmakers,including marine reptiles,chirotheriids,non-avian theropods,birds,sauropods,and ornithischian dinosaurs. Among them,the Triassic track records are dominated by marine reptiles,while the Jurassic and Cretaceous records show the dominance of saurischian. This dataset is an important supplement to the scarce bone fossils of the Late Mesozoic that contributed to the diversity of Mesozoic paleontological taxa in Guizhou Province,and provides more evidence for understanding the palaeoecology and palaeoenvironment of the Mesozoic vertebrate fauna of Guizhou Province.
