The results of the assessment predicted that The Southwestern Wyoming Province conforms to the the number of undiscovered oil accumulations of minimum Greater Green River Basin and covers an area of about 23,000 size or larger in the assessment unit ranges from a minimum square miles. Because the Permian Phosphoria Formation is of 2 to a maximum of 8 (median set at 4), with a range in size relatively high in total organic carbon, is regionally extensive, from a minimum of 0.5 to a maximum of 90 million barrels of and petroleum contained in some sub-Cretaceous stratigraphic oil (median set at 2). The predictions for the number of undis- units in the province can be genetically linked geochemically covered gas accumulations of minimum size or larger range to the Phosphoria, the Phosphoria Total Petroleum System, from a minimum of 5 to a maximum of 45 (median set at 17), covering the whole area of the province plus a 12-mile-wide with a range in size from a minimum of 3 to a maximum of strip along the western border, was established for the pur- 3,600 billion cubic feet of gas (median set at 20).

During the Early Triassic, argillaceous sediments were deposited on top of the Phosphoria, and the resulting Lower Triassic Dinwoody Formation formed a seal on the Phosphoria until disrupted by Introduction Laramide tectonism in the Late Cretaceous. Source rocks in the Phosphoria began generating oil in southeastern Idaho at The Southwestern Wyoming Province, as defined in the beginning of the Early Cretaceous, but in the Southwestern this assessment report, conforms to the so-called Greater Wyoming Province, oil generation did not commence until Green River Basin (fig. 1). The Greater Green River Basin is Late Cretaceous.

  • A Preliminary Assessment of Paleontological Resources at Bighorn Canyon National Recreation Area, Montana and Wyoming
    A PRELIMINARY ASSESSMENT OF PALEONTOLOGICAL RESOURCES AT BIGHORN CANYON NATIONAL RECREATION AREA, MONTANA AND WYOMING Vincent L. Santucci1, David Hays2, James Staebler2 And Michael Milstein3 1National Park Service, P.O. Box 592, Kemmerer, WY 83101 2Bighorn Canyon National Recreation Area, P.O. Box 7458, Fort Smith, MT 59035 3P.O. Box 821, Cody, WY 82414 ____________________ ABSTRACT - Paleontological resources occur throughout the Paleozoic and Mesozoic formations exposed in Bighorn Canyon National Recreation Area. Isolated research on specific geologic units within Bighorn Canyon has yielded data on a wide diversity of fossil forms. A comprehensive paleonotological survey has not been previously undertaken at Bighorn Canyon. Preliminary paleontologic resource data is presented in this report as an effort to establish baseline data. ____________________ INTRODUCTION ighorn Canyon National Recreation Area (BICA) consists of approximately 120,000 acres within the Bighorn Mountains of north-central Wyoming and south-central Montana B (Figure 1). The northwestern trending Bighorn Mountains consist of over 9,000 feet of sedimentary rock. The predominantly marine and near shore sedimentary units range from the Cambrian through the Lower Cretaceous. Many of these formations are extremely fossiliferous. The Bighorn Mountains were uplifted during the Laramide Orogeny beginning approximately 70 million years ago. Large volumes of sediments, rich in early Tertiary paleontological resources, were deposited in the adjoining basins. This report provides a preliminary assessment of paleontological resources identified at Bighorn Canyon National Recreation Area. STRATIGRAPHY The stratigraphic record at Bighorn Canyon National Recreation Area extends from the Cambrian through the Cretaceous (Figure 2). The only time period during this interval that is not represented is the Silurian.

U.S. Geological Survey ABSTRACT The conclusion drawn by Professor E. B. Branson in a recent paper on the "Red Beds" of the Rocky Mountain region that parts of these beds are marine is considered likely. The conclusion that there exists no basis for subdivision of the beds is not accepted, and a division of the Mesozoic part into Lower Triassic, Upper Triassic, and Jurassic units is advocated. The conclusion that no eolian deposits are present likewise is not accepted, and the interpretation of important parts of the Jurassic unit as eolian is advocated. Disagreement is expressed with much of Professor Branson's correlation table, and a substitute is offered.
