| Abstract/Notes | Cyclocystoids (range: Ordovician–Devonian), particularly of Devonian age, are extremely rare fossils and stratigraphic ranges of most taxa are little known. For this reason, the discovery of a single fragmentary specimen referable to Sievertsia (Smith and Paul, 1982) from the Traverse Formation (Middle Devonian) in Cass County, northern Indiana, deserves mention. Furthermore, the precise stratigraphic position of the cyclocystoid occurrence is documented by a combination of significant conodont and brachiopod faunas. The specimen was collected in situ on a weathered surface from a position approximately 1.2 m above the base of the type section of the Miami Bend Lithofacies (Cooper and Phelan, 1966, p. 6, U.S. National Museum Locality 391a; Orr, 1969, p. 338, Locality 5) exposed at the top of the west wall of the old France Stone Company quarry (inactive) on the north side of U.S. Highway 24, 3.2 km east of Logansport, SW¼, NE¼, sec. 27, T27N, R2E, Cass County, Indiana (Logansport 7½′ quadrangle). |
