Arretotherium Fricki, A New Miocene Anthracothere From Nebraska, J. R. Macdonald, C. Bertrand Schultz Jan 1956

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 Jun 1955

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 …


Paleosols Of The Oligocene Of Nebraska, C. Bertrand Schultz, Lloyd G. Tanner, Cyril Harvey Mar 1955

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 …

Pleistocene Evolution Of The Ohio And Wabash Valleys, William J. Wayne Nov 1952

Pleistocene Evolution Of The Ohio And Wabash Valleys, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

Studies of drift thickness and character currently in progress in Indiana indicate changes in drainage that have occurred in Indiana and some adjoining states since the beginning of the Pleistocene epoch. After late Tertiary (Lexington) peneplanation the master-drainage line, the Mahomet-Teays Valley system, became entrenched about 200 feet below its former level before it was ponded by Nebraskan ice and diverted into a new course. During the Parker cycle, which was interrupted by glaciation, the present physiographic features of southern Indiana and their now buried extensions to the north became recognizable. Static rejuvenation then was a major factor in erosion …


A Report On Drosophila Collections In Nebraska, David D. Williams, Dwight D. Miller Jan 1952

A Report On Drosophila Collections In Nebraska, David D. Williams, Dwight D. Miller

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

Until rather recently little has been known of the Drosophila species of Nebraska. Sturtevant (1921) lists Nebraska as one of seven states from which no Drosophila had been reported. Patterson and Wagner (1943) show that collections of Drosophila pseudoobscura had been made in the vicinities of Scottsbluff and Kearney, but no other Drosophila species are reported from Nebraska in their publication.


Insect Types In The Collections Of The University Of Nebraska State Museum, Martin H. Muma Jan 1952

Insect Types In The Collections Of The University Of Nebraska State Museum, Martin H. Muma

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

In 1948 the insect collections at the University of Nebraska State Museum were placed in the care of the author. Prior to that date curatorial duties were assumed or assigned to full time teaching or research staff members. As would be expected under the latter circumstances, the organization of study material and types was neglected in many families and genera. Since 1948 type material, because of its intrinsic value, has received considerable attention. All primary and representative secondary types have been assembled in three museum cases and one slide cabinet for curatorial and study convenience.

The Red Cloud Sand And Gravel, A New Pleistocene Formation In Nebraska, C. Bertrand Schultz, Eugene C. Reed, A. L. Lugn

Conservation and Survey Division: Faculty and Staff Publications

Recent studies of the stratigraphy and paleontology of the Pleistocene of Nebraska have resulted in additional data that require further clarification and partial revision of the Grand Island sand and gravel formation (1,2) in order that there may be no condusion as the results of varying usage of the term.

A Graphic Résumé Of The Pleistocene Of Nebraska (With Notes On The Fossil Mammalian Remains), C. Bertrand Schultz, Gilbert C. Lueninghoener, W. D. Frankforter

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

I T SEEMS desirable at this time to present a graphic resume of the Nebraska Pleistocene, together with a summary of the stratigraphic sequences of the fossil vertebrates. This report is based on data taken from various publications' in addition to information gathered by the present writers during the past fifteen or more field seasons. Intensive work has been done in the past five years in connection with recovery of paleontological material in the areas where government dams are under construction (Schultz, Lueninghoener, and Frankforter, 1948; Schultz and Frankforter, 1948; Holder and Wike, 1949). The information in the present paper …


Progress Report: Chemical Quality Of The Surface Waters In The Loup River Basin, Nebraska, John G. Connor Jun 1951

Progress Report: Chemical Quality Of The Surface Waters In The Loup River Basin, Nebraska, John G. Connor

United States Geological Survey: Publications

The Loup River and its tributaries transport moderate amounts of siliceous minerals from the sand hills region of north-central Nebraska to the Platte River near Columbus, Nebr. Predominant chemical characteristics of these waters are a high percentage of silica, moderate hardness, and a low percentage of sodium. The composition of the Loup River water is influenced by the geologic formations through which ground water, a major contributor to the flows of the Loup River branches, has percolated. Investigation of water quality at or near proposed dam sites in the Loup River basin indicates that if soil and drainage conditions are …

An Annotated List Of The Orthoptera Of Nebraska Part I The Blattidae, Mantidae And Phasmidae, Harold A. Hauke Jan 1949

An Annotated List Of The Orthoptera Of Nebraska Part I The Blattidae, Mantidae And Phasmidae, Harold A. Hauke

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

This paper is the first of a series on the Orthoptera of Nebraska. In 1932, while a graduate student at the University of Nebraska, the author began a taxonomic study of the Orthoptera, the result of which was an unpublished List of the Othoptera of Nebraska. The list has been studied and revised.


Preliminary Geomorphological Studies Of The Lime Creek Area & Preliminary Report On The Lime Creek Sites: New Evidence Of Early Man In Southwestern Nebraska, C. Bertrand Schultz, Gilbert C. Lueninghuener, W. D. Frankforter Nov 1948

Preliminary Geomorphological Studies Of The Lime Creek Area & Preliminary Report On The Lime Creek Sites: New Evidence Of Early Man In Southwestern Nebraska, C. Bertrand Schultz, Gilbert C. Lueninghuener, W. D. Frankforter

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

PALEONTOLOGICAL and archaeological discoveries were made near Cambridge, Nebraska, by the University of Nebraska State Museum field party in the spring of 1947 (Schultz and Frankforter, 1948, pp. 279-280) . Fossils and artifacts were found in situ at the base of a fifty-foot terrace on Lime Creek (University of Nebraska State Museum Localities Ft-41 and Ft-42) and on Medicine Creek just below the mouth of Lime Creek (Ft-50). Lime Creek is located (Fig. 1) in southwestern Nebraska in the southeastern part of Frontier County. It is a tributary of Medicine Creek which in turn is a tributary to the Republican …
