       There is a lot of mystery surrounding Iliosuchus as the genus is only based upon the description of three ilia.‭ ‬These parts are not diagnostic enough to clearly identify what kind of theropod dinosaur Iliosuchus was,‭ ‬though in England during the Mid Jurassic the dominant theropod dinosaurs were the megalosaurs.‭ ‬A similarity to some tyrannosaurs has‭ ‬been noted however,‭ ‬a link that might not be that farfetched given that tyrannosauroid genera such as Juratyrant are known to have been present in England later in the Jurassic,‭ ‬and evolution tells us that these would have needed ancestors earlier in the Jurassic,‭ ‬perhaps about the time of Iliosuchus.
