Mesozoic fossil amphibians are very rare in China, to name a few, Late Jurassic Laccotriton subsolanus, and Sinerpeton fengshanensis from the Fengshan area, Fengning County, Hebei Province, Early Cretaceous Liaoxitriton zhongjiani from Shuikouzi, Huludao, Liaoning Province, Middle Jurassic Chunerpeton tianyiensis and Jeholotriton paradoxus (Caudata) from the Daohugou area, Ningcheng, Inner Mongolia, and Early Cretaceous Liaobatrachus grahaui, Callobatrachus sanyanensis (Salientia) and Mesophryne beipiaoensis from the Jehol Biota in western Liaoning. This paper reports for the first time a fossil tadpole (Salientia) from the Middle Jurassic in the Daohugou area, Ningcheng, Inner Mongolia. It not only fills in the gap of the distribution of the Anura Amphibians in the Middle Jurassic in China, but also enriches the content of the Yanliao Biota. Therefore, it is of great value for studying the geographic distribution, the morphogeny and the living conditions of early frogs.
