"Paralligator" sungaricus, described from the Early CretaceousNenjiang Formation of Jilin Province, China, is based on postcranial remains consisting of a few presacral vertebrae, dorsal osteoderms, a partial left femur, and the proximal part of a left tibia and fibula.[6][7] However, the type material is too fragmentary to be considered diagnostic, and the species is a nomen dubium.[3] Turner (2015) also referred P. ancestralis a junior subjective synonym of P. gradilifrons.[3]
