A Preliminary Investigation Of The Taxonomy And The Geographical Distribution Of The Chrysopidae (Neuroptera) Of Utah, Wayne A. Melander

Theses and Dissertations

The writer undertook a preliminary investigation of the taxonomy and geographic distribution of a group of neuropterous insects, the Chrysopidae, in Utah. The main purposes of the investigation were to find what species and forms of these beneficial insects occur in Utah, to provide means for their identification, and to report upon their geographical distribution. Two main methods of investigation were employed. The first, a bibliographic method, was to carefully review the literature concerning the Chrysopidae of the United States for all references pertaining to their distribution and their taxonomy. The second method of investigation was to study insect specimens …

A Study Of Utah Phoridae Diptera, A. Lavell King

Theses and Dissertations

This study was undertaken to determine the present status in Utah of the Dipterous family Phoridae, and to report which genera and species are found there. The work was done with the thought in mind of furthering the knowledae of this little-known family in Utah. In order to secure information about the family the writer studied entomological literature and specimens obtained from the entomological collections of the Brigham Young University and Utah State Agricultural College. Personal collecting in various areas of Utah was also done. During the study it was found that there were six genera and twenty-one species correctly …

Arretotherium Fricki, A New Miocene Anthracothere From Nebraska, J. R. Macdonald, C. Bertrand Schultz

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

A new species of middle Miocene (early Hemingfordian) anthraco-there, Arretotherium fricki Macdonald and Schultz is described based on a cranium from the upper Marsland deposits of Nebraska. The holotype suggests that this genus was derived from the Oligocene genus Elomeryx Marsh.

Classification Of Oligocene Sediments In Nebraska: A Guide For The Stratigraphic Collecting Of Fossil Mammals, C. Bertrand Schultz, Thompson M. Stout

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

The Chadron and Brule formations constitute the White River Group in Nebraska and adjacent states. The Brule is divided into the Orella and Whitney members. The latter members are referred to the Medial and Late Oligocene (equivalents of the European Stampian and Aquitanian), while-the Chadron is equated with the Early Oligocene (Sannoisian). Each unit in Nebraska is subdivided into three parts (Lower, Middle, and Upper; or A, B, and C for the Chadron and Whitney, and A-B, C, and D for the Orella). Key beds such as fossil soils (paleosols), Purplish White beds, and volcanic ash layers, when considered with …

A Study Of The Families Of Utah Hemiptera, Gerald L. Nielsen

Theses and Dissertations

This study determines the number of families of Hemiptera found in the state and has a key for their classification. The characteristics and general distributions of each family are given, along with specific examples of the most common and economically important bugs. Important references are given for each family of work done to date. It was found that there have been twenty-eight families of Hemiptera collected in Utah, some of which are well represented in numbers of genera, species, and individuals, while others are represented by a single species and collected in only one or two places in the state.

Paleosols Of The Oligocene Of Nebraska, C. Bertrand Schultz, Lloyd G. Tanner, Cyril Harvey

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

Prominent paleosol ("buried" or "fossil" soil) complexes occur at the top of the middle Orella, upper Orella, lower Whitney, and upper Whitney in the Brule formation of Nebraska; and at the top of the "Lower Oreodon," "Middle Oreodon," "Upper Oreodon," and "Leptauchenia" beds in the Brule deposits of South Dakota. These paleosols have regional distribution and appear to be of value in stratigraphic correlations. Major faunal breaks seem to coincide with important buried soil zones, thus indicating that certain paleosols actually represent unconformities. Some of the soils were developed on old land surfaces where deposition was practically at a standstill …
