| 説明 | Fossiliferous sandstone from the Mississippian of Ohio, USA.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. In general, the Vinton is sparsely fossiliferous at best. At the Mohawk Dam emergency spillway in Coshocton County, Ohio, fossiliferous horizons are not uncommon. Shown above is the typical appearance of Vinton Member fossils - limonite-stained molds of invertebrate shells and skeletons. The bedding plane is dominated by brachiopods.Stratigraphy: Vinton Member, upper Logan Formation, Osagean Stage, upper Lower MississippianLocality: Mohawk Dam emergency spillway, northwest of the town of Nellie, western Coshocton County, eastern Ohio, USA (vicinity of 40º 21' 26.42" North latitude, 82º 04' 57.97" West longitude) |
