| Description |
Fossiliferous sandstone from the Mississippian of Ohio, USA. (4.4 cm across at its widest) The Vinton Member is the uppermost of four stratigraphic units in the Mississippian-aged, siliciclastics-dominated Logan Formation of eastern Ohio. Ascending from the base, they are the Berne Conglomerate Member, the Byer Sandstone Member, the Allensville Member, and the Vinton Member. The Vinton is dominated by siltstones but sandstones and shales are also present. The fossil molds in this sample (top & underside) include brachiopods (Rhipidomella, Chonetes, various shell fragments), a partial bryozoan colony, and a crinoid stem columnal. Chonetes = brachiopod just below center. Stratigraphy: upper Vinton Member, upper Logan Formation, upper Waverly Group, Osagean Stage, upper Lower Mississippian Locality: Toboso East Outcrop - cut on the northern side of railroad, ~0.25 miles west of Pleasant Valley Road, immediately west of small tributary creek flowing north into the Licking River, east of the town of Toboso (SW1/4 NE1/4 NE1/4, section 4, T2N, R10W), far-eastern Hanover Township, far-eastern Licking County, central Ohio, USA (40º 03' 19.80" North latitude, 82º 11' 49.37" West longitude) (= locality of Jacko (1988) - Depositional Environment & Provenance of a Sharon Conglomerate Outcrop Near Toboso, Licking County, Ohio.
