| 英文摘要 | The crocodyliform reptile Chimaerasuchus paradoxus Wu, Sues, and Sun, 1995 from the Lower Cretaceous Wulong Formation of Hubei (China) is characterized by its singular, extremely heterodont dentition. It also possesses a number of unusual cranial features including a shelf-like anterolateral expansion of the jugal, a distinct lateral process on the angular, a very small splenial, and an entirely open Meckelian canal. As in Notosuchus terrestris from the Upper Cretaceous of Argentina, the confluent external nares are large, vertically oriented, and face directly forward. Mandibular motion was apparently proal. Phylogenetic analysis indicates a sister-group relationship between Chimaerasuchus and Notosuchus, and between that clade and an as yet unnamed notosuchid from the Lower Cretaceous of Malawi. This casts further doubts on previous claims concerning the endemic distribution of the Notosuchidae and other ''Gondwanan'' tetrapod taxa during the Cretaceous.; The crocodyliform reptile Chimaerasuchus paradoxus Wu, Sues, and Sun, 1995 from the Lower Cretaceous Wulong Formation of Hubei (China) is characterized by its singular, extremely heterodont dentition.
