  • A Succession of Depositional Environments in the Mid-Ordovician Section at Crown Point, New York
    A SUCCESSION OF DEPOSITIONAL ENVIRONMENTS IN THE MID-ORDOVICIAN SECTION AT CROWN POINT, NEW YORK Brewster Baldwin 1 and Lucy E. Harding Department of Geology Middlebury College, Middlebury, Vermont 05753 Introduction The Crown Point section, exposed at the Crown Point State Historic Site, is a wonderful place for using fossils, sedimentary textures and structures, and lithologies to interpret changing environments of deposition. Formations exposed in the 120 meter (400 feet) thick section include the Crown Point, Valcour, Orwell, and Glens Falls limestones, deposited between about 458-444 million years ago on the eastern margin of North America. The rocks record the onset of the continent-arc collision known as the Taconic Orogeny. The lower half of the section records deposition on a slowly subsiding, passive continental margin. The upper half records a swift transition to deeper water environments as the continental margin entered the subduction zone. At Crown Point these rocks comprise a homoclinal section dipping about 8 degrees to the west-northwest. The Middlebury College geology department uses the Crown Point section as a field exercise for both first- and second-year geology students. Their field trip as well as yours consists of a walking tour beginning about 500 meters southeast of Fort Crown Point, heading towards and through the Fort, and then continuing west for about 200 meters along the Lake Champlain shoreline. We will visit most of the lettered stations shown on the index and air photo maps (Figs. 1 and 2). The lettered stations are also shown on the detailed columnar section (Fig. 3) and the student columnar section (Fig.

  • Species Were Accidentally Lost,But Future Shipments Will Probably
    59.9(728) Article XXXIV.- MAMMALS FROM NICARAGUA. BY J. A. ALLEN. During the last two years the Museum has received several collections of birds and mammals from Nicaragua, made by Mr. William B. Richardson, who for many years was in the employ of Messrs. Salvin and Godman as an ornithological collector in Mexico and Central America. The mammals thus far received comprise about 400 specimens, representing nearly 60 species, of which about one-fourth appear to be undescribed. This is perhaps not surprising, in view of the fact that very few mammals have been previously received from Nicaragua. The most important of Mr. Richardson's discoveries are a new and very distinct species of Bassaricyon, and a new species of spiney rat, allied to the Ecuadorian Echimys gymnurus Thomas, and representing a hitherto unrecognized genus. The collection contains also several other species which are quite differentt from any previously known. Mr. Richardson's collecting trips have covered a wide extent of country. From his home at Matagalpa, in the central part of Nicaragua, he visited the highlands to the northward and northwestward, and also the Pacific coast; eastward his explorations extended from Lake Nicaragua to the vicinity of the Atlantic coast. The principal points at which collections were made are as follows: Matagalpa, altitude about 3000 feet. San Rafael del Norte, altitude about 5000 feet. Ocotal, altitude about 4500 feet. Chinandega, on the Pacific slope, about 700 feet. Chontales, lowlands east of Lake Nicaragua, altitude about 500 to 1000 feet. Tuma and Lavala, east of Matagalpa, on the Atlantic slope, below 1000 feet.

  • The Middle Ordovician Strata
    "MIDDLE ORDOVICIAN STRATIGRAPHY AND SEDIMENTOLOGY - S01.J'l'HERN LAKE CHAMPLAIN V.ALLEY" Bruce W. Selleck Colgate University David MacLean Con-Test, Inc. Introduction: The Middle Ordovician strata (Chazy, Black River and Trenton Groups) of the Champ lain Valley record the l atter stages of passive margin deposition on the early Paleozoic continental margin of eastern North American. The onset of foredeep deve lopment, in response to loading of this portion of the continental margin during the late Medial Ordovician Taconic orogeny, in also recorded in the this section by development of generally deepening - upward facies patterns in the Black River and Trenton Gr oups . The goals of this trip a r e to examine these units in the Southern Champlain Valley, interpret the depositional environments represented, and to assess the importance of tectonic controls upon regional facies patterns. Regional Stratigraphic Framework: The bedrock geology of the Lake Champlain Valley is dominated by Cambrian and Ordovician platform strata. The abundance of exposure in the area, the relative ease of access and ear ly settl ement account for the long history of geological study in the region. Early worke rs recognized that the Pa leozoic rock units in northern and eastern New York consisted of basal sandstones (Potsdam Sandstone of Emmons, 1842) overlying h ighly deformed metamorphic basement (Grenvillian metamorphic terrain) . Basal sandstones are succeeded by mixed quartz sandstones and dolostones (Calciferous Sandrock of Emmons, 1842 and Ma ther , 1843; later included in the Beekmantown Group by Clarke and Schuchert, 1899). The Beekmantown Group is overlain by younger calcite limestones (Chazy of Emmons, 1842; Black River of Vanuxem , 1842 and Trenton Group of Conrad, 1837).

Species range in size from ,5kgto.200 kg. Among the largest amphicyonids are Old and New World species of the genus Amphicyon: A. giganteus in Europe (18±;15? Ma) and Africa, A. ingens in North America (15.9±;14.2 Ma). Amphicyon ®rst appears in the Oligocene of western Europe, surviving there until the late Miocene.
