. ''I. spinosus'' had a triple, forward-pointing horn-like spine between its eyes, very similar to the single spine of '' Trewavasia'', and a massive, multipointed spine emanating from the back of its head. It was originally placed in the family Coccodontidae, but then was transferred to "Trewavasiidae" with ''Trewavasia''. Recently, it has been placed in Gladiopycnodontidae due to recent anatomical similarities with the various genera within that family, including '' Gladiopycnodus''.
