Conodonts and Biostratigraphy of Upper Ordovician Strata along a Shelf to Basin Transect in Central Nevada
Conodonts representing 38 species of 26 genera have been identified in samples from Upper Ordovician rocks at three central Nevada localities. Ranges of these species and associated graptolites are used graphically to determine correlation of the strata considered with an evolving composite standard that includes information from Ordovician strata at more than 100 localities in North America. R...
متن کاملTriassic Lithostratigraphy and Biostratigraphy North of Currie, Elko County, Nevada
The Triassic section north of Currie in southern Elko County, Nevada, is almost 500 m thick and is assigned to the Thaynes Group and overlying Shinarump Formation of the Chinle Group. The Thaynes Group disconformably overlies the Permian Gerster Formation and is mostly calcareous shale with interbedded wackestones that yield marine invertebrate fossils, especially ammonoids. The Shinarump Forma...
متن کاملMultiyear accumulation and temperature history near the North Greenland Ice Core Project site, north central Greenland
This paper presents a comparison of two independent methods of estimating subseasonal accumulation across the interior of Greenland. These methods, highresolution snow pit studies and atmospheric modeling, have differing spatial and temporal resolution, but both can estimate net accumulation for subseasonal and shorter periods. The snow pit approach is based on a documented relationship between...
متن کاملMagnetostratigraphic calibration of Eocene^Oligocene dino£agellate cyst biostratigraphy from the Norwegian^Greenland Sea1
The presence of abundant age-diagnostic dinoflagellate cysts in Ocean Drilling Program (ODP) Hole 913B (Leg 151), Deep Sea Drilling Project Hole 338 (Leg 38) and ODP Hole 643A (Leg 104) has enabled the development of a new biostratigraphy for the Eocene^Oligocene interval in the Norwegian^Greenland Sea. This development is important because the calcareous microfossils usually used for biostrati...
متن کاملPopulation structure of graptolite assemblages
Graptolite rhabdosomes display a diverse suite of morphologies. The range of morphotypes present within most moderate to high diversity assemblages from the Ordovician and Silurian is similar, despite the different taxonomic composition of the faunas at different times. Survivorship analyses of graptolite faunas from the Ordovician and Silurian demonstrate strong similarities in the mortality r...
