Paleoecology Of Pseudozaphentoides Verticillatus (Barbour) In The Plattsmouth Limestone (Pennsylvanian), Robert Francis Diffendal Jr.

Open Access Master's Theses (through 2010)

The purpose of this paper is to (1) delineate precisely the exact areal distribution and stratigraphic position within the Plattsmouth limestone member of any occurrence of Pseudozaphrentoides verticillatus (Barbour) and (2) to study the abiotic and biotic aspects of the Plattsmouth limestone in order to offer some inferences as to the paleoecological significance of these occurrences.

The Plattsmouth limestone in Nebraska is exposed in numerous quarries along the sides of the Weeping Water valley and along the Missouri River bluffs from Plattsmouth, Nebraska south to the Queen Hill quarry. Within the Plattsmouth, corals rapidly diminish in number away from the …

Sulfur Fertilizers For Alfalfa Production In Nebraska, R. L. Fox, A. D. Flowerday, F. W. Hosterman, H. F. Rhoades, R. A. Olson

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In order to elaborate all aspects of the sulfur problem in alfalfa production, a series of field, greenhouse and laboratory experiments was initiated to determine: 1. The influence of sulfur fertilization on the yield of alfalfa in Nebraska. 2. The influence of sulfur fertilization on the protein, vitamin A, and sulfur contents of alfalfa. 3. The sulfur supplying capacities of various soils under field and greenhouse conditions. 4. The sulfur content of precipitation at widely scattered points in Nebraska. 5. Soil properties associated with sulfur deficiency. 6. Optimum methods for estimating the sulfur status of soils by soil testing. The …

Lithostratigraphy And Correlation Of The Mississippian System In Nebraska, Marvin P. Carlson

Conservation and Survey Division: Faculty and Staff Publications

The purpose of this study is to describe and correlate rocks of Mississippian age within the state of Nebraska. Shales, generally classified as "Chattanooga" and commonly referred to as Devonian or Mississippian in the northern Mid-Continent, have been included in this study, although these shales are more generally believed to be Devonian and not Mississippian by most stratigraphers and paleontologists at the present time. Since rocks of Mississippian age are present only in the subsurface of Nebraska, the basic information for this report is derived from the microscopic study of cuttings and cores from test wells drilled within the state.

Paleontologic Investigations At Big Bone Lick State Park, Kentucky: A Preliminary Report, C. Bertrand Schultz, Lloyd G. Tanner, Frank C. Whitmore Jr., Louis L. Ray, Ellis C. Crawford

United States Geological Survey: Staff Publications

The Big Bone Lick area in Ketttucky, the first widely known collecting locality for vertebrate fossils in North America is being investigated for further faunal and geologic evidence. Mammal bones, ranging in age from Wisconsin (Tazewell?) to Recent were recovered in 1962 from four different faunal zones in two terrace fills.

The Bdellidae (Acarina) Of The Australian Realm, Warren T. Atyeo

Bulletin of the University of Nebraska State Museum (1924–2023)

Although primarily a systematic study, variations in the integumental striae and chaetotaxy of the legs are discussed. The genus Octobdellodes Atyeo, 1960 is synonymized with Bdellodes Oudemans, 1937 and the sugenus Cytobdella Mihelcic, 1958 is synonymized with Cyta von Heyden, 1826. The genus Bdellodes is divided into the subgenera Bdellodes and Hoploscirus Thor, 1937 (=Thoribdella Grandjean, 1938, new synonymy). Twenty-two species are now known to occur in New Zealand and the outlying islands. These include four known species: Bdella iconica, Bdellodes (Roploscirus) lapidaria, B. (R.) reticulata, and Cyta latirostris, and eighteen new species: Bdellodes (Bdellodes) harpax, B. (B.) oraria, …

Pleistocene Formations In Indiana, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

The system of stratigraphic classification used in North America for all sedimentary rock units except nonmarine deposits of the Pleistocene Series established groups, formations, and smaller units based on objectively determined characteristics of the rocks and not on geomorphology or subjective features, such as geologic time. Not all students of the nonmarine Pleistocene have kept these two kinds of units distinct from each other. The Pleistocene sediments of Indiana and the surrounding States are continental in origin rather than marine, and thus they show far less lithologic homogeneity than sediments and rocks of marine origin. Nevertheless, these Pleistocene sediments can …

Development Of Water Quality Criteria For Aquatic Life, Clarence M. Tarzwell

United States Environmental Protection Agency: Publications

It is now recognized that water pollution is an important problem, that it becomes more widespread and serious as population and industry expand, and that something must be done if aquatic life resource are to be saved and their productivity maintained. In the past there has been a great deal of uncertainty in approaching this situation and a general lack of understanding of the details and ramification of the overall problem. In the efforts for the abatement of pollution, only a few clearcut objectives have been established. Knowledge is lacking as to what the objectives should be. There is still …

A Soil And Vegetation Inventory And Analysis Of Three Nebraska Sandhills Range Sites, Donald F. Burzlaff

Nebraska Agricultural Experiment Station: Historical Research Bulletins

This study was undertaken to inventory the soils and vegetation of certain areas of the Sandhills and to seek edaphic characteristics that may be the limiting factor in the distribution of various plant species. Information of this nature will permit formulation of more accurate management practices because of a refinement in delineation of range sites.

A Middle Miocene Rhinoceros Quarry In Morrill County, Nebraska (With Notes On Hip Disease In Diceratherium), Robert M. Stecher, C. Bertrand Schultz, Lloyd G. Tanner

Bulletin of the University of Nebraska State Museum (1924–2023)

Extensive deposits of fossil rhinoceros bones have been excavated from University of Nebraska State Museum collecting localities Mo-113, -114, -115, -116, and -118 some 8 1/2 to 9 1/2 miles north of Bridgeport, Morrill County, Nebraska. The fossils were associated with other faunal elements in the lower portion of the Marsland formation (middle Miocene) of the Hemingford group. The rhinoceros is considered to be Diceratherium niobrarensis Peterson, geologic variety. A pathologic right femur of D. niobrarensis provides evidence of hip disease in the medial Miocene rhinoceroses.

Early Records Of Some Mammals From Nebraska, J. Knox Jones Jr.

Bulletin of the University of Nebraska State Museum (1924–2023)

Ten species of Recent mammals that formerly occurred in Nebraska have been extirpated there by European man. Surprisingly few specimens of the species concerned are preserved in museum collections. Perusal of a representative segment of the historical literature pertaining to Nebraska has revealed records of occurrence of most of the extirpated species that provide a basis for estimating the former distribution of each in the State.
