The Echinoderm fauna of the Brassfield Formation (Lower Silurian, Early to Middle Llandoverian) contains more than 30 species and is locally common in southern Ohio making it one of the most important Early Silurian faunas known (Foerste, 1919, 1936; Ausich, 1984a, 1984b, 1985, 1986a, 1986b, 1986c, 1987; Ausich and Schumacher, 1984; Ausich and Dravage, 1988). At present, the Brassfield Formation has produced two callocystitid rhombiferans including Brockocystis nodosariusFoerste (1919) and Anartiocystis foersteiAusich and Schumacker (1984). Neither of these taxa is well-known, being described from a...
