Martin Sander Institute of Palaeontology, University of Bonn, Nussallee 8, 53115 Bonn, Germany The palaeoecology of basal turtles from the Late Triassic was classically viewed as being semi-aquatic, similar to the lifestyle of modern snapping turtles. Lately, this view was questioned based on limb bone proportions, and a terrestrial palaeoecology was suggested for the turtle stem. Here, we present independent shell bone microstructural evidence for a terrestrial habitat of the oldest and basal most well- known turtles, i.e. -

Marcos Jannello 2018 Resumen Las inusuales estructuras óseas observadas entre los vertebrados, como el cuello largo de la jirafa o el cráneo en forma de T del tiburón martillo, han interesado a los científicos desde hace mucho tiempo. Uno de estos casos es el clado Testudinata el cual representa uno de los grupos más fascinantes y enigmáticos conocidos entre de los amniotas. Su inconfundible plan corporal, que ha persistido desde el Triásico tardío hasta la actualidad, se caracteriza por la presencia del caparazón, el cual encierra a las cinturas, tanto pectoral como pélvica, dentro de la caja torácica desarrollada. Esta estructura les ha permitido a las tortugas adaptarse con éxito a diversos ambientes (por ejemplo, terrestres, acuáticos continentales, marinos costeros e incluso marinos pelágicos). Su capacidad para habitar diferentes nichos ecológicos, su importante diversidad taxonómica y su plan corporal particular hacen de los Testudinata un modelo de estudio muy atrayente dentro de los vertebrados. Una disciplina que ha demostrado ser una herramienta muy importante para abordar varios temas relacionados al caparazón de las tortugas, es la paleohistología. Esta disciplina se ha involucrado en temas diversos tales como el origen del caparazón, el origen del desarrollo y mantenimiento de la ornamentación, la paleoecología y la sistemática. -

Large Igneous Provinces and Mass Extinctions: an Update
Downloaded from specialpapers.gsapubs.org on April 29, 2015 OLD G The Geological Society of America Special Paper 505 2014 OPEN ACCESS Large igneous provinces and mass extinctions: An update David P.G. Bond* Department of Geography, Environment and Earth Science, University of Hull, Hull HU6 7RX, UK, and Norwegian Polar Institute, Fram Centre, 9296 Tromsø, Norway Paul B. Wignall School of Earth and Environment, University of Leeds, Leeds LS2 9JT, UK ABSTRACT The temporal link between mass extinctions and large igneous provinces is well known. Here, we examine this link by focusing on the potential climatic effects of large igneous province eruptions during several extinction crises that show the best correlation with mass volcanism: the Frasnian-Famennian (Late Devonian), Capi- tanian (Middle Permian), end-Permian, end-Triassic, and Toarcian (Early Jurassic) extinctions. It is clear that there is no direct correlation between total volume of lava and extinction magnitude because there is always suffi cient recovery time between individual eruptions to negate any cumulative effect of successive fl ood basalt erup- tions. Instead, the environmental and climatic damage must be attributed to single- pulse gas effusions. It is notable that the best-constrained examples of death-by- volcanism record the main extinction pulse at the onset of (often explosive) volcanism (e.g., the Capitanian, end-Permian, and end-Triassic examples), suggesting that the rapid injection of vast quantities of volcanic gas (CO2 and SO2) is the trigger for a truly major biotic catastrophe. Warming and marine anoxia feature in many extinc- tion scenarios, indicating that the ability of a large igneous province to induce these proximal killers (from CO2 emissions and thermogenic greenhouse gases) is the single most important factor governing its lethality. -

What is power? What does it mean to possess power, and to exercise it over or against others? What are the resources and conditions that make people and groups powerful or powerless, and how do power relations condition interactions between persons? How can we study So wrote L.L.

Eureka Valley Groundwater Basin Bulletin 118
South Lahontan Hydrologic Region California’s Groundwater Eureka Valley Groundwater Basin Bulletin 118 Eureka Valley Groundwater Basin • Groundwater Basin Number: 6-16 • County: Inyo • Surface Area: 129,900 acres (203 square miles) Basin Boundaries and Hydrology This groundwater basin underlies Eureka Valley in northeastern Inyo County. This basin is bounded by nonwater-bearing rocks of the White Mountains on the north, of the Inyo Mountains on the west, of the Saline Range on the south, of the Last Chance Range on the east, and of the Sylvania Mountains on the northeast (Jennings 1958, DWR 1964, Strand 1967). Willow creek and unnamed washes carry runoff to Eureka (dry) Lake at the southeastern end of the valley. Average annual precipitation ranges from about 5 inches on the valley floor to 10 inches on the surrounding mountains (DWR 1964). Hydrogeologic Information Water Bearing Formations The primary water-bearing material consists of younger, unconsolidated alluvial fan material and underlying, semi-consolidated older alluvial deposits. The alluvium reaches at least 640 feet thick and groundwater in it is generally unconfined (Bader 1969, DWR 1964). Like most internally drained basins, the alluvium likely becomes interbedded with lacustrine silt and clay layers near Eureka Lake. Restrictive Structures. Some small faults are mapped as cutting Quaternary alluvial deposits in this basin (Strand 1967); however, it is not known whether or not these faults impede groundwater movement in the basin. Recharge Areas Replenishment of the basin is from percolation of runoff from the surrounding mountains through alluvial fans (Bader 1969). Groundwater likely flows southward toward Eureka Lake and perhaps southeastward into Saline Valley (Bader 1969, DWR 1964).
