Abstract: This paper describes a new genus of Early Cretaceous batrachian fossil discovered in Longjiang Group in Daur Autonomous Banner of Morin Dawa, east Inner Mongolia. The new type mainly has the following characteristics:The width is longer than the length of its head. There are lots of teeth on the maxillary and the premaxillary. Two nasals are connected in the middle line. The parasphenoid is like a stripe. The pterygoid is big. The squamosal and the surpascapula are all preserved well. The near-end place of the coracoid is obviously intumescentia. The new specimen has 8 opisthocoelous presacrals with developed transverse processes, and its second to the fourth presacrals have free ribs. Only the near-end places of the ribs are intumescentia. The sacral has hatchetshaped transverse processes. The urostyle has transverse processes at the near-end place. The tibiale and the fibulare cicatrize only at the near-end and the far-end places. This specimen is another new discovery of Mesozoic anuran fossils in China, in addition to Liaobatrachus.
