Summary
[edit]DescriptionSmall mud nodules (Vinton Member, Logan Formation, Lower Mississippian; Rt. 16 roadcut, northeast of Frazeysburg, Ohio, USA) 5 (12799889815).jpg |
The small, rounded structures are nodules in Mississippian siliciclastic sedimentary rocks. The overhanging rocks at top are sandstone. The gray rocks below are mudshales. At this site, the nodules often contain one or two fossils - usually lingulid brachiopods (Lingula sp.). Other observed fossils include orbiculoid brachiopods and a new species of ammonoid cephalopod, Polaricyclus n.sp. Stratigraphy: Vinton Member, upper Logan Formation, Osagean Series, upper Lower Mississippian Locality: Trinway West 6 Outcrop - roadcut on the northwestern side of Rt. 16, 1.0 miles northeast of the Rt. 16-Old Riley Road intersection, northeast of the town of Frazeysburg & west of the town of Trinway, northwestern Muskingum County, Ohio, USA (40° 08' 41.54" North latitude, 82° 05' 06.18" West longitude) |
