Huronia (cephalopod)
Huronia is an actinocerid genus included in the Huroniidae along with Discoactinoceras and Huroniella,(Teichert 1964). Huronia is characterized by long siphuncle segments with the free part of the connecting rings only slightly inflated and by a narrow central canal and strongly curved radial canals located in the anterior part of each siphuncle segment == Ancestry == Teichert, (1964) indicated Huronia as being derived from the upper Middle Ordovician Discoactinoceras, whose ancestry lay in the direction of Polydesmia, once considered the prototypical actinocerid.
