It belongs to the crocodilian-like clade Neochoristodera and was initially assigned to the Champsosauridae by Sigogneau-Russell (1981). 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.
