The Hualongdong Site in Dongzhi County, Anhui Province, is a well-known Middle Pleistocene archaeological site in East Asia associated with late archaic hominin activities. Here we initially report several postcranial snake fossils that discovered from Loc.1. In this study, we conducted a preliminary identification of these specimens based on integrative osteological comparison between fossils and extant snakes. Three families, five genera, and six extant species were identified, which can be attributed to extant taxa. Diagnosis for each identified genus was summarized. The zoogeographic composition of the snake assemblage is primarily characterized by South China, Oriental, and Monsoonal elements. Among them, the Oriental tropical type Ptyas cf. carinata is most frequently recorded. The snake fauna might reveal a warmer and more humid climate in Hualongdong Site during the late Middle Pleistocene compared to the present.
