The Position and Age of the Sciotoville Bar Locality, Southern Ohio
The Sciotoville Bar was a rock ledge exposed along the northeast bank of the Ohio River between the Little Scioto River and Wolfred Run (NEJ4, sec. 8, T2N, R20W, Scioto County, Ohio). This well-known fossil locality yielded an abundant fauna from concretions in a shale which formed a portion of the ledge. Since 1920, however, the locality has been flooded by the pool created first from construction of Lock and Dam 31, and later by the Captain Anthony Meldahl Locks and Dam. Information assembled from various sources indicates that the main concretionary horizon represents the upper portion of the Portsmouth Member of the Cuyahoga Formation. In addition, a previously unpublished measured section of this locality by Hyde is now available which describes the location of the concretionary fossil-bearing horizon. The combined ammonoid fauna from the upper Cuyahoga and the overlying lower Logan Formation suggests a Kinderhookian rather than Osagean age for the concretionary horizon.
The Mississippian ammonoids Karagandoceras and Kazakhstania from Ohio
The poorly known ammonoid genera Karagandoceras and Kazakhstania are sparsely represented in the upper Cuyahoga and lower Logan Formations of Ohio. Karagandoceras bradfordi, n. sp. from the Byer Member of the Logan Formation, is the first North American record of this genus. Voehringerites, n. gen. (type species: Karagandoceras peracutum Vihringer) is erected for specimens from the H6nnetal, Sauerland, West Germany, previously included in Karagandoceras. Collectively, ammonoids from the upper Cuyahoga and lower Logan Formations suggest a Kinderhookian age assignment for this stratigraphic interval.
The faunas of the Tournaisian Tulcumba Sandstone and its members in the Werrie and Belvue synclines, New South Wales
Abstract The faunas of the Tulcumba Sandstone and its member, the Rangari Limestone, from the western edge of the Werrie and Belvue synclines of western New England are described. The stratigraphical and palaeontological data are considered to indicate a Tournaisian (Kinderhookian) age. The gastropods and lamellibranchs include several Devonian holdovers, and the affinities of the brachiopods are as much with late Devonian as with Carboniferous forms. The trilobite genus Australosutura is shown to be much longer ranging than was previously thought to be the case. Most of the species described are new and are not known from units higher in the Carboniferous in New South Wales. One new chonetoid brachiopod genus, Tulcumbella with type species T. microstriata n.sp., and one new trilobite genus Weania, with type species W. goldringi n.sp., are described. Other new brachiopods are Acanthatia rangariensis, Spirifer lirellus sol, Tylothyris minima, Brachythyris solida and Cranaena concava. New polyzoans are Evac...
