       Rolfosteus is a genus of arthrodire placoderm fish that lived in Australia during the Devonian.‭ ‬Though small for an arthrodire placoderm,‭ ‬the stand out feature of Rolfosteus is the enlarged snout.‭ ‬The specific purpose of this snout is still unknown,‭ ‬but fish that develop such a feature usually do so as a form of sensor suite,‭ ‬having a heightened ability to detect things such as smells to even electrical impulses from prey that otherwise might be hidden.
