  • 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.

  • Bulletin 19 of the Department of Geology, Mines and Water Resources
    COMMISSION OF MARYLAND GEOLOGICAL SURVEY S. JAMES CAMPBELL Towson RICHARD W. COOPER Salisbury JOHN C. GEYER Baltimore ROBERT C. HARVEY Frostburg M. GORDON WOLMAN Baltimore PREFACE In 1906 the Maryland Geological Survey published a report on "The Physical Features of Maryland", which was mainly an account of the geology and min- eral resources of the State. It included a brief outline of the geography, a more extended description of the physiography, and chapters on the soils, climate, hydrography, terrestrial magnetism and forestry. In 1918 the Survey published a report on "The Geography of Maryland", which covered the same fields as the earlier report, but gave only a brief outline of the geology and added chap- ters on the economic geography of the State. Both of these reports are now out of print. Because of the close relationship of geography and geology and the overlap in subject matter, the two reports were revised and combined into a single volume and published in 1957 as Bulletin 19 of the Department of Geology, Mines and Water Resources. The Bulletin has been subsequently reprinted in 1961 and 1966. Some revisions in statistical data were made in the 1961 and 1968 reprints. Certain sections of the Bulletin were extensively revised by Dr. Jona- than Edwards in this 1974 reprint. The Introduction, Mineral Resources, Soils and Agriculture, Seafood Industries, Commerce and Transportation and Manu- facturing chapters of the book have received the most revision and updating. The chapter on Geology and Physiography was not revised. This report has been used extensively in the schools of the State, and the combination of Geology and Geography in one volume allows greater latitude in adapting it to use as a reference or textbook at various school levels.
