Extinct genus of molluscs
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. Flower, (1968) on the other hand, showed that "Huronia" is derived from "Actinoceras" and split off from "Lambeoceras" during Red River time, near the start of the Late Ordovician, precluding the inclusion of "Discoactinoceras"
Distribution.
"Huronia" is known from the Upper Ordovician and Silurian of North America and Greenland. "H. arctica" and "H occidentalis"(?) are associated with the Cape Calhoun fauna in Greenland.(Flower 1957) "H paulodolata" and "H munuens" come from the Middle Silurian of Michigan (Teichert 1964) "H sepata" is found in the Shamattawa limestone of Hudson Bay (Flower 1957)
