. Such incomplete material is inadequate for accurate classification, nonetheless,
Iliosuchus has been tentatively considered a tyrannosaurid ancestor. This is unlikely to be correct as the bones cannot be distinguished from small individuals of
Megalosaurus, a megalosaurid. Whatever the case,
Iliosuchus is not diagnostic and is therefore a
nomen dubium.
