Course Objectives: Historical Geology provides the student with a comprehensive survey of the history of life, and major events in the physical development of Earth. Most importantly, this class addresses how processes like plate tectonics and climate interact with life, forming an integrated system. The first half of the class focuses on concepts, and the second on a chronologic overview of major biological and physical events in different geologic periods.

  • Mammalia, Felidae, Canidae, and Mustelidae) from the Earliest Hemphillian Screw Bean Local Fauna, Big Bend National Park, Brewster County, Texas
    Chapter 9 Carnivora (Mammalia, Felidae, Canidae, and Mustelidae) From the Earliest Hemphillian Screw Bean Local Fauna, Big Bend National Park, Brewster County, Texas MARGARET SKEELS STEVENS1 AND JAMES BOWIE STEVENS2 ABSTRACT The Screw Bean Local Fauna is the earliest Hemphillian fauna of the southwestern United States. The fossil remains occur in all parts of the informal Banta Shut-in formation, nowhere very fossiliferous. The formation is informally subdivided on the basis of stepwise ®ning and slowing deposition into Lower (least fossiliferous), Middle, and Red clay members, succeeded by the valley-®lling, Bench member (most fossiliferous). Identi®ed Carnivora include: cf. Pseudaelurus sp. and cf. Nimravides catocopis, medium and large extinct cats; Epicyon haydeni, large borophagine dog; Vulpes sp., small fox; cf. Eucyon sp., extinct primitive canine; Buisnictis chisoensis, n. sp., extinct skunk; and Martes sp., marten. B. chisoensis may be allied with Spilogale on the basis of mastoid specialization. Some of the Screw Bean taxa are late survivors of the Clarendonian Chronofauna, which extended through most or all of the early Hemphillian. The early early Hemphillian, late Miocene age attributed to the fauna is based on the Screw Bean assemblage postdating or- eodont and predating North American edentate occurrences, on lack of de®ning Hemphillian taxa, and on stage of evolution.

  • Geologic Timeline
    SCIENCE IN THE PARK: GEOLOGY GEOLOGIC TIME SCALE ANALOGY PURPOSE: To show students the order of events and time periods in geologic time and the order of events and ages of the physiographic provinces in Virginia. BACKGROUND: Exact dates for events change as scientists explore geologic time. Dates vary from resource to resource and may not be the same as the dates that appear in your text book. Analogies for geologic time: a 24 hour clock or a yearly calendar. Have students or groups of students come up with their own original analogy. Before you assign this activity, you may want to try it, depending on the age of the student, level of the class, or time constraints, you may want to leave out the events that have a date of less than 1 million years. ! Review conversions in the metric system before you begin this activity ! References L.S.

Abstract: The tribe Microtoscoptini, comprising the genera Microtoscoptes from Eurasia and Paramicrotoscoptes and Goniodontomys from North America, is an enigmatic group of microtoid cricetids, which was widespread during the Late Miocene. Although fossil remains have been reported from 33 localities, their evolutionary and dispersal history is still poorly understood. Here we give an overview of sites and records and discuss temporal ranges and some aspects of the dispersal history.

Both series were founded by Dr. Bryant Walker, Mr. Bradshaw H. Swales, and Dr. W. W. Newcomb. Occasionally the Museum publishes contributions outside of these series. Beginning in 1990 these are titled Special Publications and Circulars and each is sequentially numbered. All submitted manuscripts to any of the Museum’s publications receive external peer review. The Occasional Papers, begun in 1913, serve as a medium for original studies based principally upon the collections in the Museum. They are issued separately. When a sufficient number of pages has been printed to make a volume, a title page, table of contents, and an index are supplied to libraries and individuals on the mailing list for the series. The Miscellaneous Publications, initiated in 1916, include monographic studies, papers on field and museum techniques, and other contributions not within the scope of the Occasional Papers, and are published separately. Each number has a title page and, when necessary, a table of contents. A complete list of publications on Mammals, Birds, Reptiles and Amphibians, Fishes, I nsects, Mollusks, and other topics is available.

  • GEOLOGY THEME STUDY Page 1
    NATIONAL HISTORIC LANDMARKS Dr. Harry A. Butowsky GEOLOGY THEME STUDY Page 1 Geology National Historic Landmark Theme Study (Draft 1990) Introduction by Dr. Harry A. Butowsky Historian, History Division National Park Service, Washington, DC The Geology National Historic Landmark Theme Study represents the second phase of the National Park Service's thematic study of the history of American science. Phase one of this study, Astronomy and Astrophysics: A National Historic Landmark Theme Study was completed in l989. Subsequent phases of the science theme study will include the disciplines of biology, chemistry, mathematics, physics and other related sciences. The Science Theme Study is being completed by the National Historic Landmarks Survey of the National Park Service in compliance with the requirements of the Historic Sites Act of l935. The Historic Sites Act established "a national policy to preserve for public use historic sites, buildings and objects of national significance for the inspiration and benefit of the American people." Under the terms of the Act, the service is required to survey, study, protect, preserve, maintain, or operate nationally significant historic buildings, sites & objects. The National Historic Landmarks Survey of the National Park Service is charged with the responsibility of identifying America's nationally significant historic property. The survey meets this obligation through a comprehensive process involving thematic study of the facets of American History. In recent years, the survey has completed National Historic Landmark theme studies on topics as diverse as the American space program, World War II in the Pacific, the US Constitution, recreation in the United States and architecture in the National Parks.

  • Environmental Geology Chapter 2 -‐ Plate Tectonics and Earth's Internal
    Environmental Geology Chapter 2 - Plate Tectonics and Earth’s Internal Structure • Earth’s internal structure - Earth’s layers are defined in two ways. 1. Layers defined By composition and density o Crust-Less dense rocks, similar to granite o Mantle-More dense rocks, similar to peridotite o Core-Very dense-mostly iron & nickel 2. Layers defined By physical properties (solid or liquid / weak or strong) o Lithosphere – (solid crust & upper rigid mantle) o Asthenosphere – “gooey”&hot - upper mantle o Mesosphere-solid & hotter-flows slowly over millions of years o Outer Core – a hot liquid-circulating o Inner Core – a solid-hottest of all-under great pressure • There are 2 types of crust ü Continental – typically thicker and less dense (aBout 2.8 g/cm3) ü Oceanic – typically thinner and denser (aBout 2.9 g/cm3) The Moho is a discontinuity that separates lighter crustal rocks from denser mantle below • How do we know the Earth is layered? That knowledge comes primarily through the study of seismology: Study of earthquakes and seismic waves. We look at the paths and speeds of seismic waves. Earth’s interior boundaries are defined by sudden changes in the speed of seismic waves. And, certain types of waves will not go through liquids (e.g. outer core). • The face of Earth - What we see (Observations) Earth’s surface consists of continents and oceans, including mountain belts and “stable” interiors of continents. Beneath the ocean, there are continental shelfs & slopes, deep sea basins, seamounts, deep trenches and high mountain ridges. We also know that Earth is dynamic and earthquakes and volcanoes are concentrated in certain zones.
