Trace and Body Fossils from the Cuyahoga Formation (Mississippian), Reynoldsburg,OhioA ThesisPresented in Partial fulfillment of the requirementsfor the degree Bachelor of Sciencein Geological SciencesbyAddison O.

Associated body fossils found are Platycrinities sp.,Gilbertsocrinus? sp., Dictyoclostus sp., Fenestrellina sp., and unidentifiable blastoidfragments. At the Reynoldsburg locality, deposition is interpreted to have taken place in ashallow water setting near an ancient deltaic environment.IntroductionThe purpose of this paper is to describe and interpret trace and body fossils fromthe former William M. Forrester Quarry in Reynoldsburg, Ohio (Figures 1, 2). Thisformer quarry is now called Pine Quarry Park. The former quarry exposes sanstones ofthe Lower Mississippian Cuyahoga Formation. The fossils are interpreted to be from theBuena Vista Member of the Cuyahoga Formation (Figure 3). The rocks are rich in tracefossils but body fossils are uncommon. Bryozoans, crinoids, blastoids, and brachiopods1are present, as are various trace fossils. Some layers of rock have numerous trace fossilson the undersides of beds.Stratigraphic SettingThe Buena Vista Member of the Cuyahoga Formation lies just above the Henley Shaleand below the Rarden Member in southern Ohio. The unit grades into the VanceburgMember toward the north (Coogan et. aI., 1981). In Pine Quarry Park, 6.2 meters oftheBuena Vista Member are exposed (Figures 2,3). The rocks in the Buena Vista member ofthe Cuyahoga Formation are interbedded [me-grained sandstone and/or siltstone with thingray shale layers. The fine-grained sandstone layers are tan-brown to blue-gray. Thesandstone layers are of varying thickness and have flute marks along the bottoms of somebeds. Tracks and trails that seem to resemble Gordia can be seen along the bottom ofsome beds, too. One of the sandstone layers shows convolute bedding. The siltstonelayers are tan-gray and are thinly bedded. The shale layers are thin, commonly about 10centimeters. One shale layer has a dark gray color and has small organic bits in it.Siderite layers, iron concretions, and iron staining are common throughout the quarry.Low in the section the beds, particularly in the stream, show soft sediment deformationstructures.The Buena Vista Member extends from southeastern Ohio to northern Kentucky,where it is contained in the Borden Formation (Coogan et. al., 1981).The environmental setting of the Buena Vista is interpreted to be a nearshoresetting that grades eastward into a barrier bar-deltaic environment (Bork, 1979). This issupported by the fine-grained sandstone/siltstone interbedded with gray shale. Theselithologies grade upward into coarser sandstone deposits (Bork, 1979). The trace fossils2found in the quarry represent the Cruziana in this locality since the traces Gordia,Scalartuba, and Planolites were found in Pine Quarry Park along with Zoophycos traces.These traces, other than Zoophycos normally represent areas that are shallow shelves, notbelow wave base (Rhoads, 1975). Zoophycos cannot always be used as a depth indicatorfor rocks (Miller, 1991). The body fossils of crinoids, brachiopods, and bryozoans suggestthat this environment was a shallow marine setting.The stratigraphic placement of the Buena Vista Member has been somewhatcontroversial. Previous work done on the Lower Mississippian rocks was done by Hydein 1915 and 1921, Stockdale in 1939, Holden in 1942, Fagadau in 1952, and morerecently by Coogan et. al. In 1981.Systematic PaleontologyTrace FossilsGordia Emmons, 1844Figure 4Remarks.- Gordia includes long slender trails, straight to gently curved having uniformthickness and smooth sides. The trails are found on the underside of the bed ashypichnia. Most specimens from Reynoldsburg are 4 to 5 em long and are about 2 to 3mm in diameter. Sediment in the trails seems to be of the same composition as thesediment in the rock. Some trails have an iron staining that is present along the marginsof the trails. The trails cross over and through one another but none of the trails seem to3branch. Gordia has been interpreted as a grazing trail of a worm or worm-like creature(Hantzschel 1975).Helminthopsis Herr, 1877Figure 5Remarks- Simple meandering trails that have a fairly smooth texture are assigned toHelminthopsis. Meanders are widely spaced run in a more-or-less straight direction. Themeandering trails have diameters ranging from 8 to 11 millimeters for the trails inhyporelief and 5 to 6 millimeters for trails that are in epirelief. Some of the hyporelieftrails have smalileminscate ridges that run perpendicular along the trails. The hyporelieftrails also show sediment "piled" up around the trails. The sediment in the matrix seemsto match the sediment that comprises the trails. Both types of trails run parallel along thebedding plane. The hyporelief and the epirelief trails are considered part of the sameichnogenus because they only differ in the mode of preservation. This dosen't mean theyare part of the same ichnospecies.Laevicyclus Quenstedt, 1879Figure 6Remarks- Vertical tubes that run perpendicular to the bedding are assigned toLaevicyclus. The tubes are marked by concentric lamination around the walls of the tubes.The diameter of the tubes range from 4 millimeters to 13 millimeters. These vertical tubeswere probably living or feeding structures of a worm-like animal. These tubes obviously4mark an area of higher energy than the other traces since most of the other traces are onthe bedding plane and not down inside the sediment.Phycosiphon- von Fischer-Goster, 1858Figure 7Remarks- Small V-shaped loops that are usually branched and found parallel or obliqueto bedding are assigned to Phycosiphon. They represent hypichnia and endichinia feedingtraces that have diameters of 1 mm. The branching antler-shaped characteristic is noteasily recognized. The V-shaped loops seem to be disconnected and there are traces thatare several centimeters in length. There is a distinct color difference between the tracesand the rock. These traces are thought to be feeding burrows of worm-like animals(Hantzschel 1975).Planolites Hall, 1847Figure 8Remarks- Burrows that are basically straight, smooth walled, and sinuous to obliquelyoriented to the surface are assigned to Planolites. Commonly the burrows are unbranchedbut they can be found intersecting one another. The diameter of the burrows ranges from2 to 4 mm. Many specimens branch from a single point and run oblique to the bedding.They stand out because the burrows are a black gray color against a brown-gray rock.Some samples just show single straight burrows but have the same characteristics of theother burrows. These are thought to be trace of infaunal worm-like animals (Hantzschel1975).5Scalartuba Weller, 1899Figure 9Remarks- Burrows that are subcylindrical and either parallel or oblique to bedding areassigned to Scalarituba. Most have prominent scalariform or meniscus ridges. Burrowsseem to be 3 to 4 mm in diameter. Length of the trails is variable. The trails do not crossthrough each other but the trails can be on different planes. Some of the trails seem tobranch but none of the specimens show this very well. There is a color contrast betweenthe burrow and the surrounding rock The burrows are a darker black-gray color against agreenish-gray rock. They are possible internal trail made by a worm of worm-likeorganism that lived in a shallow marine setting (HantzscheI1975).Zoophycos Massalongo, 1855Figure 10, 11Remarks-Flat planar spherical markings on tops of bedding planes with a cylindrical tubethat is perpendicular to the bedding plane are assigned to Zoophycos. The tube isconnected to the flat planar spherical marking almost radial design, on the top of thebedding plane. There is a small ridge or point that protrudes from around the center of thestructure. Underneath this ridge is a vertical tube that goes down into the rock. Thesetubes seem to be made of concentric lamination of a dark gray to black very fine grainmaterial that is different from the fine grained, tan-brown sandstone matrix. The radiatingstructure on the top of the rock is also made of this dark gray to black very fine grained6material. The radiating structure can range in size from 3 to 7 cm. The vertical tubes canextend vertically at least 7 cm. The tube has a diameter of about 1 cm. This structure istentatively interpreted as a feeding structure made by a soft-bodied worm-like animals.Body FossilsPhylum BrachiopodaClass ArticulataOrder StrophomenidaDictyoclostus sp. Muir-wood, 1930Figure 12Remarks- One convex valve of a productid brachiopod was found. The valve hascontinuous radiating ridges that are not interrupted as in Buxtonia. Dictyoclostus iscommonly found elsewhere in the Cuyahoga Formation (Rocque and Marple, 1985).Phylum BryozoaClass CryptestomataFenestrellina sp. D'Orbigny, 1849Figure 13Remarks- Bryozoan colonies having branching and net-like forms are interpreted torepresent Fenestrellina. Fenestrellina sp. and related genera are in the CuyahogaFormation (Rocque and Marple, 1985).7Phylum EchinodermataClass CrinoideaGilbertsocrinus? sp. Phillips, 1836Figure 14Remarks- Single circular columnal with crenularium, narrow areola, narrow perilumen,and a circular lumen is assigned to Gilbertsocrinus. The identification is questionablebecause only one columnal was found.Platycrinites sp.- Miller, 1821Figure 15Remarks-Basal and radial plates of the calyx have been found. They are identified asPlatycrinites because they a fused basal plate instead of three separate unequal basalsradials. Oval columnal plates which are characteristic of Platycrinites, have not beenfound.Class BlastoideaUndetermined BlastoidRemarks- A single undetermined radial plate of a blastoid was found.ConclusionsPine Quarry Park in Reynodsburg Ohio contains fine-grained sandstone/siltstoneinterbedded with thin gray shale layers. The traces fossils found represent the Cruziana8ichnofacies. The environmental setting is interpreted to be a shallow water near shorearea. Marine body fossils include brachiopods and echinoderms.9ReferencesBork, K.M., 1979, Paleoenvironments ofthe Cuyahoga and Logan Formations(Mississippian) of Central Ohio.
