I Approved by ~ (advisor) ~lo/ ii ABSTRACT The Maquoketa Formation (Upper Ordovician-Cincinnatian Series) has been extensively studied for over one hundred years, but a petrographic study of its cyclic lithologies has been neglected. The following six distinct Maquoketa lithologies have been recognized in this study in Pike County, Missouri& 1) phosphatic biosparite, 2) phos phorite, 3) micrite-microsparite, 4) dolomitic shale, 5) dolomitic marlstone, and 6) dolomitic quartz siltstone. Three cycle types are present in the Maquoketa. They are expressed as thin beds (1-20 inches) of alternating micrite-shale, micrite-marlstone, and shale-siltstone. -
Paleozoic Stratigraphic Nomenclature for Wisconsin (Wisconsin

Ostrom"'" INTRODUCTION The Paleozoic stratigraphic nomenclature shown in the Oronto a Precambrian age and selected the basal contact column is a part of a broad program of the Wisconsin at the top of the uppermost volcanic bed. It is now known Geological and Natural History Survey to re-examine the that the Oronto is unconformable with older rocks in some Paleozoic rocks of Wisconsin and is a response to the needs areas as for example at Fond du Lac, Minnesota, where of geologists, hydrologists and the mineral industry. The the Outer Conglomerate and Nonesuch Shale are missing column was preceded by studies of pre-Cincinnatian cyclical and the younger Freda Sandstone rests on the Thompson sedimentation in the upper Mississippi valley area (Ostrom, Slate (Raasch, 1950; Goldich et ai, 1961). An unconformity 1964), Cambro-Ordovician stratigraphy of southwestern at the upper contact in the Upper Peninsula of Michigan Wisconsin (Ostrom, 1965) and Cambrian stratigraphy in has been postulated by Hamblin (1961) and in northwestern western Wisconsin (Ostrom, 1966).

Sivon Department of Geology University of Illinois Urbana, Illinois Abstract: The Maquoketa Group (Upper Ordovician) is poorly exposed in eastern Wisconsin. The most extensive exposure is found along Wequiock Creek, about 10 kilometers north of Green Bay. There the selection includes a small part of the upper Scales Shale and good exposures of the Fort Atkinson Limestone and Brainard Shale. The exposed Scales Shale is 2.4 m of clay, uniform in appearance and containing no apparent fossils. Limestone and dolomite dominate the 3.9 m thick Fort Atkinson Limestone. The carbonate beds alternate with layers of dolomitic shale that contain little to no fauna. The shales represent times of peak terrigenous clastic deposition in a quiet water environment. The car- bonates are predominantly biogenic dolomite and biomicrite. Biotic succession within single carbonate beds includes replacement of a strophomenid-Lepidocyclus dominated bottom community by a trep- ostome bryozoan-Plaesiomys-Lepidocyclus dominated community. Transported echinoderm and cryptostome bryozoan biocalcarenites are common. -
An Inventory of Trilobites from National Park Service Areas
Sullivan, R.M. and Lucas, S.G., eds., 2016, Fossil Record 5. New Mexico Museum of Natural History and Science Bulletin 74. 179 AN INVENTORY OF TRILOBITES FROM NATIONAL PARK SERVICE AREAS MEGAN R. NORR¹, VINCENT L. SANTUCCI1 and JUSTIN S. TWEET2 1National Park Service. 1201 Eye Street NW, Washington, D.C. 20005; -email: [email protected]; 2Tweet Paleo-Consulting. 9149 79th St. S. Cottage Grove. MN 55016; Abstract—Trilobites represent an extinct group of Paleozoic marine invertebrate fossils that have great scientific interest and public appeal. Trilobites exhibit wide taxonomic diversity and are contained within nine orders of the Class Trilobita. A wealth of scientific literature exists regarding trilobites, their morphology, biostratigraphy, indicators of paleoenvironments, behavior, and other research themes. An inventory of National Park Service areas reveals that fossilized remains of trilobites are documented from within at least 33 NPS units, including Death Valley National Park, Grand Canyon National Park, Yellowstone National Park, and Yukon-Charley Rivers National Preserve. More than 120 trilobite hototype specimens are known from National Park Service areas. INTRODUCTION Of the 262 National Park Service areas identified with paleontological resources, 33 of those units have documented trilobite fossils (Fig. 1). More than 120 holotype specimens of trilobites have been found within National Park Service (NPS) units. Once thriving during the Paleozoic Era (between ~520 and 250 million years ago) and becoming extinct at the end of the Permian Period, trilobites were prone to fossilization due to their hard exoskeletons and the sedimentary marine environments they inhabited. While parks such as Death Valley National Park and Yukon-Charley Rivers National Preserve have reported a great abundance of fossilized trilobites, many other national parks also contain a diverse trilobite fauna. -
