Callobatrachus is an extinct genus of discoglossid anuran amphibian from the Early Cretaceous-age Yixian Formation of Liaoning, China.[1] It was described in 1999 by K. Gao of the American Museum of Natural History and Y. Wang of the Chinese Academy of Sciences.[2] The discovery is notable for documenting the earliest and sole definite discoglossid fossil from the Mesozoic. Callobatrachus is considered to be the most basal member of Discoglossidae based on phylogenetic analysis.[1]
