Microfossils From The Upper Severy Shale (Pennsylvanian) Near Dubois, Nebraska, Robert F. Diffendal Jr.
Microfossils From The Upper Severy Shale (Pennsylvanian) Near Dubois, Nebraska, Robert F. Diffendal Jr.
School of Natural Resources: Faculty Publications
Organic rich limestone nodules within the Severy Shale Formation collected directly above the Nodaway Coal Member near DuBois, Nebraska, have yielded a rich microflora and microfauna. The microflora includes Triletes megaspores, seeds, cuticle, and pieces of wood with well preserved structures. The microfaunal skeletal material is either partially or completely replaced by pyrite, marcasite, or, in rare cases, by sphalerite. The following major invertebrate groups and genera within these groups have been identified to date: Bryozoa (one undetermined genus); Brachiopoda (Juresania) ; Gastropoda (four undetermined genera); Ammonoidea (one undetermined genus); Ostracoda (Amphissites, Coryellites, Hollinella, Macrocypris); Echinoidea (five spine types); and …

The Pierre-Niobrara Unconformity In Western Nebraska, Harold M. Degraw
The Pierre-Niobrara Unconformity In Western Nebraska, Harold M. Degraw
Conservation and Survey Division: Faculty and Staff Publications
The Pierre-Niobrara unconformity, one of several significant unconformities in the Cretaceous System of the Western Interior region, has not generally been recognized. Detailed correlation of electric logs of a large number of wells in western Nebraska provides evidence of its existence. Isopach maps of the beds occupying three identifiable stratigraphic intervals - a redefined Niobrara Formation, an unnamed uppermost Niobrara unit, and an unnamed basal Pierre unit, which includes the Ardmore Bentonite - provide recognizable geologic patterns that permit reconstruction of the stages of development of the unconformity. The upper part of the Niobrara Formation has been truncated in several …

Epeirogenic And Climatic Controls Of Early Pleistocene Fluvial Sediment Dispersal In Nebraska, K. O. Stanley, William J. Wayne
Epeirogenic And Climatic Controls Of Early Pleistocene Fluvial Sediment Dispersal In Nebraska, K. O. Stanley, William J. Wayne
Department of Earth and Atmospheric Sciences: Faculty Publications
The change from Pliocene to Pleistocene fluvial sedimentation in Nebraska is denoted by gravel with relative enrichment of mechanically weak rock species and a two-fold increase in largest clast size. These changes in fluvial sediments suggest modification in degradational energy affecting detritus apparently related to deterioration of climate in the early Pleistocene. Cooler Pleistocene climates with increased moisture resulted in greater discharge and carrying capacity for streams headed in the Rocky Mountains and flowing across Nebraska. These streams carried granitic detritus eastward toward the continental glacier margin in easternmost Nebraska. There, streams flowing off ice sheets carrying sedimentary and metamorphic …
