Arkelloceras is an early Middle Jurassic (Bajocian stage) Stephanoceratoid (Ammonitina) genus from arctic Canada, Alaska, and Siberia belonging to the family Otoitidae (Imlay 1984, Westermann 1965) Arkelloceras seems to be a direct descendant of Abbasites and is thought to have given rise to Ermoceras and possibly to Thamboceras.
