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.

  • Physical Stratigraphy of the Phosphoria Formation in Northwestern Wyoming
    Physical Stratigraphy of the Phosphoria Formation in Northwestern Wyoming GEOLOGICAL SURVEY BULLETIN 1042-E CONTRIBUTIONS TO ECONOMIC GEOLOGY PHYSICAL STRATIGRAPHY OF THE PHOSPHORIA FORMATION IN NORTHWESTERN WYOMING By Richard P. Sheldon ABSTRACT The rocks of the Ph'osphoria formation in northwestern Wyoming fall into five stratigraphic units, which, from oldest to youngest, are provisionally called the A, B, C, D, and E units. Units A, C, and E are composed dominantly of chert, carbonate rock, and sandstone, whereas units B and D are composed dominantly of mudstone, phosphorite, and dark carbonate rock. Units C and D are con­ tinuous over all of northwestern Wyoming, whereas unit A grades into unit B and unit -E grades into unit D to the southwest. Both units A and B pinch out to the north. With the possible exception of unit A, these units can be recognized in southwestern Montana. Units B, C, and D are. equivalent to the phosphatic phale, Rex, and upper shale .members of the Phosphoria formation in southeastern Idaho. The formation as a whole exhibits a facies change from dominantly chert, mudstone, and phosphorite in the southwestern part of northwestern Wyoming, to dominantly Carbonate rock and sandstone in the northeastern part. The facies change with thinning and pinching out of units and the intergradation of units, " .. - . The rocks of the formation in the area of the report are cyclically deposited. The rock record of a single ideal cycle consists, from base to top, of carbonate rock, chert, phosphorite, chert, and carbonate rock. Sandstone and glauconite in general are found in the carbonate phase of the cycle, whereas mudstone, pyrite,.and organic matter are found in the chert and phosphorite phases of the cycle.
