Ikechosaurus is an extinct genus of choristodere reptile which existed in China and Mongolia during the Early Cretaceous.[2] It contains the species Ikechosaurus sunailinae and Ikechosaurus gaoi. It belongs to the crocodilian-like clade Neochoristodera and was initially assigned to the Champsosauridae by Sigogneau-Russell (1981).[1] Compared to other neochoristoderes, Ikechosaurus has a rather simple dentition, lacking the speciations seen in latter species. It also has parasphenoid palatal teeth, a feature not seen in any other choristodere.[3][4]
